Why Join Us?
Keet is a fully peer-to-peer messaging and video calling app built on Holepunch's P2P stack. There are no servers, no middlemen, and no data harvesting. People talk directly to each other, with end-to-end encryption by design.
We're taking Keet to a billion users, competing head-on with WhatsApp and Telegram. Product sets the direction. We're looking for a Product Engineering Lead to turn that direction into features people love, built to a standard that holds up at global scale.
You lead the teams that build Keet's features: the API team, which adds feature-focused APIs to Keet's core, and the frontend team, which builds the React app on top, each with its own lead. You report directly to the CTO and take direction from product. Product owns the what and the why. You own the how and the engineering bar. The split is roughly 70% engineering leadership and 30% product.
You're a combination of three things. You're an engineering leader who has helped teams ship consumer products at speed. You have real product sense and can partner with PMs as an equal, shaping what gets built, not just executing it. And you have an intuition for distributed, local-first systems, so you can work fluently on top of a P2P engine without needing to build it yourself.
Responsabilities
Engineering
Run the API and frontend teams day to day: unblocking, reviewing, and keeping them shipping.
Set and hold a high engineering bar for performance, reliability, and clean APIs.
Own the technical design of features and the API surface between Keet's core and the app.
Make sure the API team works closely with our deep tech teams on code reviews, design, and anything that touches the engine.
Product Partnership
Work alongside Keet's product managers to turn vision and roadmap into scoped, buildable work.
Push back when scope and reality don't match, and propose better paths when they exist.
Bring an engineering perspective to product decisions, especially where P2P opens doors that centralized apps can't.
Help the team move fast, using AI tools and quick prototypes to validate ideas before committing to them.
Leadership
Create clarity around team goals and make sure everyone knows what success looks like.
Mentor team leads to build strong team operating systems, improve how their teams work with others, and grow as leaders.
Lead by example: roll up your sleeves when the team needs it, and step back when they're ready to own it.
Experience managing engineers or engineering leads who ship consumer product, ideally in chat, calling, or social apps.
Strong product sense: you can tell a good feature from a busy one.
Intuition for distributed and local-first systems. Offline-first and eventual consistency should feel natural. You don't need P2P protocol expertise, because our core abstracts it away.
Deep JavaScript and React.
Initiative, curiosity, resilience, and the ability to give and receive direct critique.
Bonus: experience with local-first apps, CRDTs or sync engines, offline-capable mobile or desktop apps, or open source.

Role
As Director of Product you own Orcrist’s entire product portfolio - Orcrist’s OIP and Civitas’ Sentinel, and lead the product organisation. You decide what Orcrist builds and in which order: what becomes platform and what stays customer-specific, which customer problem is solved next, and how we measure that it has been solved. Our promise is demonstrable the effectiveness of our software, and making that promise deliverable is the core of this role. You work directly with Engineers, our Government Development-Team and our customers and report to the COO of Orcrist.
What you’ll do
Own product strategy
and the portfolio roadmap across all product lines – including the decision about what becomes shared platform and what remains customer-specific engineering.
Build and lead the product organisation
: hire and develop Product Managers for the product lines and align them on common standards for discovery, prioritisation and delivery.
Make
product effectiveness
and
customer activity & usage
a measurable product goal: define metrics, measurement logic and the subsequent tasks that are triggered by that.
Own discovery
with our Government Development team and our customers, and
translate their requirements into product decisions
rather than collecting feature requests.
Decide prioritisation
across competing customer, tender and platform demands, and defend those decisions to customers, the team and the management.
Plan deliverable releases
together with Engineering and QA, holding the balance between speed, quality and platform capability.
Assess market
, competitive and technology developments in the defence and simulation space and feed them into product strategy.
About you

Experience in defence, GovTech or data fusion (own military or law enforcement background is an advantage).
Experience with data analytics platforms.
Proven track record of delivering products from discovery through to customer rollout – with nameable outcomes, not just roadmaps.
Experience with B2B or B2G products in long, formal procurement cycles and with demanding enterprise or public sector customers.
Experience holding platform decisions against customer-specific exceptions – and explaining the commercial consequence of both paths.
Ability to decide with incomplete information, take ownership, and work in an environment without mature processes.
Excellent communication skills in German and English across various hierarchy levels.
Authorization to work in Germany and willingness to travel to customers (approx. 10-20%).
Nice-to-haves
Experience with on-premise, offline or air-gapped products and their consequences for product decisions is an advantage.

A little bit about us:
We are Belvo, an open finance API platform with the bold vision of democratizing access to financial services in Latin America. We enable any financial innovator to access and interpret financial data, as well as initiate payments from their end-users accounts. We’re turning the messy complexities of the Latin American financial ecosystem into a modern set of tools to access and interpret data and move money in a seamless and secure way.
We’re a highly-technical, passionate, and driven team. We are more than 90 people and our team currently represents 20 nationalities. We have offices in São Paulo and Mexico City – while a large portion of us work remotely.
We are tackling a very stimulating problem: connecting fintech innovators with legacy financial infrastructure. We strive to go beyond the limits of what is possible today and to do so in an elegant and developer-first way.
Since starting our adventure in May 2019, we have raised $71m from the leading VC investors globally.
You can read more about our company here https://belvo.com/about/ and about our team and culture here https://belvo.com/careers/. Also, head to our blog https://belvo.com/blog/ for more news about what we’re building and how we work https://belvo.com/blog/category/working-belvo/.
About the team:
- We work in cross-functional, autonomous teams. We follow continuous delivery best practices executed on top of a modern technology stack.
- Our products are built for developers, by developers. Technological excellence is at the heart of what we do.
- We are pragmatic and customer-focused. We strive to find the right set of trade-offs in order to validate our hypothesis as early as possible, iterating on our products based on customer feedback.
- We communicate transparently. We do weekly all-hands where we get together to discuss company performance and goals.
- While we are global and remote-friendly, we also operate from our vibrant offices in CDMX and Sao Paulo. To accommodate the various time zones in which we are based, we ensure we’re always synced up for at least 3 hours per day.
- Also, we are backed by some of the leading investors in Silicon Valley and Latin America, including Founders Fund, Kaszek Ventures, and YCombinator.
The challenge
The Intelligence Squad is Belvo's AI enabler team. One part of the squad builds the platforms and patterns that let every team at Belvo ship AI. This role sits in the other part: turning the financial data and payments we aggregate across Latin America into models that make real decisions, who looks creditworthy, which transaction is fraudulent, what category a payment belongs to, whether an income statement checks out. That data drives real financial outcomes for the people and businesses on the other end, so the bar for rigor is high.
You'll be the data science reference in the squad. We're not hiring someone to execute a modeling backlog someone else wrote. We want someone who decides which problems are worth modeling, defines how we know a model is good enough, and raises the data science bar for everyone they work with. You'll be deep enough in statistics and ML to defend a modeling choice to anyone, whether this is a set of rules to simplify a problem or a complex model that you build. You'll be close enough to the business to turn a commercial problem into a modeling roadmap and a business case. And you'll be a strong enough engineer to take your models from notebook to production and own them there.
Responsibilities
- Model development and selection: Lead the design of statistical and ML models (classification, regression, ranking, NLP or LLM-based) for problems like risk scoring, fraud detection and transaction categorization. Choose approaches on their merits and defend those choices with data, not habit.
- AI-leveraged delivery: Use agentic coding and research tooling as a core part of how you work: exploring data, generating and testing feature hypotheses, scaffolding pipelines, writing the service around the model. We care about the decisions you ship, not hours at the keyboard, and we expect you to keep compressing the gap between the two.
- Feature engineering with business context: Work with Product and the business teams to figure out which signals in Belvo's financial data actually explain the outcome you're modeling, and translate an ambiguous business question into a well-scoped modeling problem.
- Productionization and ownership: Take models past the notebook. Build or shape the pipelines, APIs and services that run them reliably in production, and own them once they're live: monitoring, drift, retraining, and retirement when the evidence says so.
- Experimentation: Design and run experiments (A/B tests and offline evaluation) to confirm that a model change actually moves the metric it's meant to move.
- Cross-functional partnership: Work closely with Engineering, Data Research, Product, and the rest of the Intelligence Squad to ship end to end, and with stakeholders across the business to keep your models grounded in what actually matters to them.
- Business and customer partnership: Work directly with stakeholders and, when needed, customers. Translate ambiguous business questions into well-scoped problems, and explain trade-offs and impact clearly to non-technical audiences, executives included.
- Staying current: GenAI moves weekly. We expect you to be genuinely plugged in: model releases, papers, and tooling, to hold an opinion on what's real versus hype, and to bring the useful parts back to the squad as a demo, a doc, or a session for our company-wide AI Chapter.
- Framing the problem: Decide what's worth modeling. Push back when a rule, a heuristic, or a better data pipeline solves the problem without a model, and be willing to kill or retire your own model when the evidence says so.
This position may be for you if
- 5+ years of experience as a Data Scientist, Applied Scientist, or in a similar hands-on modeling role.
- You've owned models end to end in production, from framing the problem to monitoring it live, and you can point to the measurable business impact they had.
- You have a solid grounding in statistics and can explain how your models work at that level, not just how to call them.
- You've built and compared more than one type of model (for example tree-based methods, regression, deep learning) for the same problem and can justify why you picked the one you shipped.
- You're comfortable in Python for data science (pandas, scikit-learn, and at least one of TensorFlow or PyTorch) and in SQL for pulling and shaping your own data.
- You've taken several models you built into production yourself, not just handed it off to someone else to deploy.You http://deploy.You understand engineering fundamentals: testing, version control, CI/CD, and how to write code someone other than you can maintain.
- You've built with LLMs past the API-call level: tool use or agents, retrieval, structured outputs, and shipped at least one to production. You can explain how you knew it was good enough, which means you've built some form of evaluation, not just eyeballed outputs.
- Agentic coding tools are part of your daily workflow, not a novelty. You can walk us through a specific task that used to take you days and now takes hours: how you set it up, what you delegated, and where you still don't trust the output.
- You're proficient in written and spoken English.
Amazing if
- You've worked in fintech, financial risk, or another regulated data environment before.
- You have a business or strategy background alongside data science (an MBA, consulting, or a product/strategy role).
- You've worked in a customer-facing data science role, such as a forward-deployed engineer or a solutions/applied team at a data platform company.
- You've worked with MLOps tooling for model versioning, monitoring, and automated retraining.
- You've deployed models on AWS (for example SageMaker or an equivalent managed ML service).
- You've written evals or an LLM-as-judge harness for a non-deterministic system, and have opinions about where that approach breaks.
- You've used LLMs inside the data pipeline itself: labeling, extraction, categorization, and can say where they beat a classical model and where they quietly don't.
Tech stack
- Python is our primary language for data science and modeling (pandas, scikit-learn, and deep learning frameworks as needed).
- SQL against a cloud data warehouse for data access and feature work.Claude deployed company-wide and Claude Code for every engineer. Agentic tooling is part of how we work daily, not a side experiment.
- Cloud infrastructure on AWS, favoring managed services so you can focus on the modeling problem rather than infrastructure plumbing.
- An experimentation platform for A/B testing and offline evaluation.
- We use Datadog for service observability across the company.
- We follow Continuous Integration and Continuous Delivery best practices.
Our tech stack:
- We’re building our platform using modern technologies, putting the focus on reliability and long-term maintainability
- We primarily use Python on the backend. We use battle-tested technologies such as Django, and we are heavy users of Python’s asyncio for some parts of our stack
- We use Javascript, Vue.js and Sass on the frontend. We are developing and leveraging our own design system and component library
- We run our infrastructure on top of Amazon Web Services, leveraging managed services. We tend to favor the use of managed services wherever possible, in order to focus on our business problems
- We observe and monitor our services using Datadog
- We follow Continuous Integration and Continuous Delivery best practices
Our process steps:
At Belvo every hire is so important to us, that we share the decision to hire as a team.
- People team chat
- Take-home challenge

SENIOR DATA ENGINEER
ABOUT KEYROCK
Since our beginnings in 2017, we've grown to be a leading change-maker in the digital asset space, renowned for our partnerships and innovation.
Today, we partner with over 250 team members around the world. Our diverse team hails from 42 nationalities, with backgrounds ranging from self-taught DeFi natives to PhDs. Predominantly remote, we have hubs in London, Brussels, and Singapore, and host regular online and offline hangouts to keep the crew tight.
We are trading on more than 80 trading venues, and working with a wide array of asset issuers. As a well-established market maker, our distinctive expertise led us to expand rapidly. Today, our services span market making, options trading, high-frequency trading, OTC, and DeFi trading desks.
But we’re more than a service provider. We’re an initiator. We're pioneers in adopting the Rust Development language for our algorithmic trading, and champions of its use in the industry. We support the growth of Web3 startups through our Accelerator Program. We upgrade ecosystems by injecting liquidity into promising DeFi, RWA, and NFT protocols. And we push the industry's progress with our research and governance initiatives.
At Keyrock, we're not just envisioning the future of digital assets. We're actively building it.
ABOUT THE TEAM AND WHY THE ROLE EXISTS
The Central Data Team (CDT) is only a few months old, but data has been Keyrock's lifeblood since day one. We're now building the Keyrock Data Platform to give Keyrockers, and the AI agents working alongside them, the data and context they need to act fast and autonomously within agreed boundaries and aligned with our shared goals. Doing that means taking data from across the company and making sense of it in real time for all the functions that depend on it: trading desks, wealth and asset management, product, risk, finance, compliance, and research to name a few.
You'd be one of the early hires in CDT and we expect you to contribute to most of the bigger decisions and build work. The standards we settle on and the way the team ends up working are still open.
WHAT YOU’LL DO
- Build streaming and batch pipelines that ingest, normalise, and distribute market, trading, and portfolio data, resilient to feed and exchange failures.
- Build the self-serve tooling (SDKs, patterns, templates, AI agents) so other teams publish, consume, and build on data products without waiting on us.
- Own data contracts and schema evolution. Keep schema changes from turning into multi-team coordination events.
- Design the lakehouse and time-series layer around consumer query patterns.
- Build and evolve the Data Governance and Data Quality Framework: stale-feed detection, schema validation, range checks, idempotent writes, lineage, ownership, self-healing.
- Build the derived analytics the business runs on: cross-exchange spreads, VWAP at depth, order book microstructure for the desks; portfolio views, exposure, performance for wealth and asset management.
- Make observability, cost, and performance first-class from day one.
- Treat infrastructure as code (Docker, Terraform, CI/CD) alongside our Central Infrastructure Team.
- Work in the open: write things down, partner closely with Architecture, Infrastructure, Platform, and the rest of the teams.
WHAT WE’RE LOOKING FOR
Tools matter less to us than how you think about problems. That said, here's the shape of the person we have in mind.
Engineering Craft
- 8+ years of building production data systems that other people rely on.
- Strong proficiency in Python and SQL: not just being able to write a query, but being able to reason about what the engine is doing with it.
- Code that's easy for someone else to read, test, and delete later.
- Strong understanding of data modelling for both streaming and analytical workloads.
- Efficiency, quality, idempotency, and observability are taken seriously by default.
Systems Design
- You've designed and operated streaming systems on Kafka, Redpanda, MSK, or Kinesis, and you have opinions about partitioning, consumer groups, offsets, and schema registries.
- You've used a time-series store in production (ClickHouse ideally; TimescaleDB, QuestDB, or similar are fine too) and can talk about table design as a function of query patterns.
- You've worked with a lakehouse architecture and reason about table layout, partitioning, and compaction as design choices that shape query performance and storage cost.
- You build for self-healing and idempotency. Reprocessing is safe, retries don't double-write, and the system recovers without a human in the loop.
Operational Readiness
- Docker, Terraform, and CI/CD are how you work, not a separate "DevOps" thing.
- You think about cost and performance early.
- You instrument as you build: logs, metrics, and traces are part of the system from day one.
- You design for data quality and governance up front covering contracts, validation, lineage, and ownership
How You Think and Work
- You reason from first principles when a problem is new, stay pragmatic when it isn't, and update your view when you learn more.
- You treat the trading desks, wealth and asset management, product, risk, finance, compliance, and research as customers of what you build, and communicate with them that way.
- You optimise for outcomes over output. A smaller, simpler thing that ships and works beats a bigger thing that doesn't.
- You take ownership end-to-end: design, ship, operate, improve.
- You say what you think including when it's an unpopular take. You change your mind when the argument is better.
- You make the people around you better. Reviews are real, juniors grow from working with you, and peers want to work with you again.
- You're curious about how markets work. Data engineering on its own won't keep you interested here.
- You're honest about what you know and what you don't, and quick to close the gap.
- You understand financial market data: order books, trades, reference data, portfolios, exposures. Crypto, TradFi, or both are a strong plus.
NICE TO HAVE
- Lakehouse experience with Apache Iceberg or Delta Lake.
- Familiarity with DataHub or similar metadata/lineage platforms.
- Rust. Some of our performance-critical services are written in it. Interest is welcome; fluency isn't required.
WHAT YOU’LL GET
- A from-scratch mandate. You'll be among the first hires in CDT, and the platform, the standards, and the team culture are yours to shape with us.
- Strong partners. Close working relationships with Architecture, Infrastructure, Platform, and the desks themselves. You won't be building data in a vacuum.
- Autonomy on how you work. Flexible hours, remote-first, business-hours on-call shared across the team.
- A competitive salary package, with various benefits.
- A team that likes each other. Regular online get-togethers and a yearly onsite where everyone's in the same room.
OUR RECRUITMENT PROCESS
We’re after those with the right skills and a conscious choice to join our field. The perfect fit? Someone who’s driven, collaborative, acts with ownership and delivers solid, scalable outcomes. As an employer we are committed to building a positive and collaborative work environment. We welcome employees of all backgrounds, and hire, reward and promote entirely based on merit and performance. Due to the nature of our business and external requirements, we perform background checks on all potential employees, passing which is a prerequisite to join Keyrock

- Drive our campaign strategy: Build an integrated, full-funnel campaign portfolio spanning paid media, organic search, web, email, content, social, OOH, print, and account-based programs. Give every program a clear audience, message, channel role, and business objective.
- Turn business priorities into pipeline: Translate company priorities by account, vertical, buyer, and region into programs that support acquisition, deal acceleration, and customer expansion. Balance always-on programs with launches and high-impact market moments.
- Build Sierra’s named-account motion: Orchestrate always-on account-based marketing for Sierra’s highest-priority accounts.
- Own investment and performance: Set pipeline targets, manage budgets, and determine the right channel and program mix. Partner with our operations team on attribution, forecasting, reporting, and lead flow. Use performance data to scale what works, stop what does not, and reallocate investment quickly.
- Set the standard for execution: Establish clear campaign planning, briefing, quality assurance, launch, and optimization rhythms. Inspect high-impact work personally and ensure Sales has the messaging, assets, and follow-up needed to convert engagement into opportunities.
- Build and lead the team: Hire, coach, and develop a high-performing team of digital marketing and campaigns professionals. Establish clear ownership, strong operating rhythms, and a culture of accountability, experimentation, and continuous improvement.
- Use AI to multiply impact: Embed AI and automation across research, audience development, content adaptation, experimentation, and reporting. Increase the team’s speed and reach while maintaining human judgment, accuracy, and brand quality.

- Strong data fluency, including attribution, forecasting, experimentation, funnel analysis, and translating performance into clear investment recommendations.
- The ability to move between executive-level strategy and detailed campaign decisions without losing speed or quality.
- Strong cross-functional leadership and executive communication skills, especially across Sales, Operations, Finance, and Marketing.
- Practical fluency with AI-powered marketing tools and sound judgment about where automation improves performance and where human expertise remains essential.
EVEN BETTER...

- A track record of creating industry specific campaigns that engage senior executives and drive measurable pipeline within priority accounts.
- Experience expanding marketing programs internationally, with a strong understanding of how buyer needs, messaging, and channels vary across markets.
