500M+ downloads. 80M+ monthly users. A decade of building – and we’re still accelerating.
Flo is the world’s #1 health & fitness app worldwide on a mission to build a better future for female health. Backed by a $200M investment led by General Atlantic, we became the first product of our kind to reach a $1B valuation in 2024 – and we’re not slowing down.
With 7M paid subscribers and the highest-rated experience in the App Store’s health category, we’ve spent 10 years earning trust at scale. Now, we’re building the next generation of digital health – AI-powered, privacy-first, clinically backed – to help our users know their body better.
The job
Build systems that power the #1 Health App for Women
We’re not a startup guessing what might work anymore, we’re operating at serious scale. Flo is used by 1 in 4 women aged 18–44 in the US. And we just hit our biggest month ever with 8.6M installs and a 2.8M MAU jump. The engineering behind that? Complex, distributed, secure and yours to help shape.
At Flo, backend engineering is core product work.
We build:
Data-driven health insights that genuinely change lives
Distributed systems that stay fast, available and scalable under massive real-time demand
Privacy-first features like Anonymous Mode - recognised in TIME’s Best Inventions
Tooling and platforms that help Flo’s teams move faster, with fewer bottlenecks
We’re tech-agnostic when hiring for backend. If you’ve built and run distributed systems and want to work in Scala (or already do), great. We’ll support your ramp-up. What matters most: you can solve problems, own outcomes, and keep learning.
Your Experience
You’ll thrive here if you:
Have 7+ years’ experience building distributed backend systems
Know what it takes to make systems fast, reliable and secure and when to prioritise each
Are fluent in Java, Scala, Python or similar (and curious enough to learn Scala with us)
Get DevOps, databases (SQL and NoSQL) and love designing APIs that just work
Have a strong handle on writing clean, documented, version-controlled code
Take ownership, show initiative and don’t wait to be told
Are product-minded and always thinking about the end-user impact
Bonus if you’ve worked with:
Stream processing
Public cloud infrastructure (AWS, GCP etc.)
What’s in it for you?
You’ll join a senior engineering team that moves fast, thinks big and builds tech used by millions daily. You’ll work on meaningful problems with real impact - in health, privacy and scale. This isn’t just code for the sake of code. This is building the future of personalised health.

You’ll be working with people who take their work seriously, not themselves. It takes commitment, resilience, and the drive to keep going when things get tough. Because better health outcomes are worth it.

We support impact with meaningful reward. Here’s what that looks like:

Staff Backend Engineer - L6
The Company
Toters is an on-demand e-commerce and delivery platform that enables customers to get anything in their city with the highest level of convenience.
At Toters, technology drives everything we do. Our product teams build features that simplify customers' lives, while our engineers create scalable solutions and optimize internal processes to deliver faster and more cost-effectively. If you thrive in a high-growth startup environment and want to help reshape how people shop across the Middle East, join us.
Description
As a Staff Backend Engineer, you will be responsible for shaping and delivering large-scale, cross-team systems and initiatives that significantly impact product reliability, performance, developer productivity, and business outcomes. You will mentor and grow multiple engineers, drive technical strategy within and across teams, resolve organization-level ambiguity, and proactively raise the bar for engineering excellence.
You combine deep hands-on expertise with strong strategic thinking, owning complex domains end-to-end while influencing roadmaps, architecture standards, and team processes at a broader scale.
Key Responsibilities
Lead the design, architecture, and delivery of large, cross-system features, platforms, or infrastructure components that span multiple teams and quarters-long timelines.
Drive technical and architectural decisions for entire domains or product areas, defining long-term strategy, surfacing major trade-offs, and aligning stakeholders across engineering, product, and operations.
Own end-to-end system health: Establish observability, reliability practices, performance baselines, and incident response patterns that prevent recurring issues across services.
Mentor and coach engineers, provide career guidance, technical pairing, code/design reviews.
Identify and eliminate systemic bottlenecks in development velocity, testing, deployment, or onboarding; build shared tools, frameworks, patterns, or automation adopted team-wide or org-wide.
Champion and evolve engineering standards, best practices, and conventions; influence adoption across multiple teams through clear reasoning, documentation, and leading by example.
Increase engineering leverage by enabling other teams to move faster and more safely through better architecture, shared abstractions, technical guidance, and reusable patterns."
Collaborate deeply with product, design, legal, and operations to challenge requirements, refine scopes, assess technical feasibility/risk, and ensure compliance (e.g., privacy, KYC).
Lead architecture and design discussions at the team-of-teams level; write detailed specs, RFCs, and decision records that enable async alignment and reduce future rework.
Act as a technical escalation point during major incidents, guiding resolution across domains and preventing recurrence through post-mortems and systemic fixes.

About Anthropic
Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.
About the Role:
Anthropic's ML Performance and Scaling team trains our production pretrained models, work that directly shapes the company's future and our mission to build safe, beneficial AI systems. As a Research Engineer on this team, you'll ensure our frontier models train reliably, efficiently, and at scale. This is demanding, high-impact work that requires both deep technical expertise and a genuine passion for the craft of large-scale ML systems.
This role lives at the boundary between research and engineering. You'll work across our entire production training stack: performance optimization, hardware debugging, experimental design, and launch coordination. During launches, the team works in tight lockstep, responding to production issues that can't wait for tomorrow.
Responsibilities:
Own critical aspects of our production pretraining pipeline, including model operations, performance optimization, observability, and reliability
Debug and resolve complex issues across the full stack—from hardware errors and networking to training dynamics and evaluation infrastructure
Design and run experiments to improve training efficiency, reduce step time, increase uptime, and enhance model performance
Respond to on-call incidents during model launches, diagnosing problems quickly and coordinating solutions across teams
Build and maintain production logging, monitoring dashboards, and evaluation infrastructure
Add new capabilities to the training codebase, such as long context support or novel architectures
Collaborate closely with teammates across SF and London, as well as with Tokens, Architectures, and Systems teams
Contribute to the team's institutional knowledge by documenting systems, debugging approaches, and lessons learned
You May Be a Good Fit If You:
Have hands-on experience training large language models, or deep expertise with JAX, TPU, PyTorch, or large-scale distributed systems
Genuinely enjoy both research and engineering work—you'd describe your ideal split as roughly 50/50 rather than heavily weighted toward one or the other
Are excited about being on-call for production systems, working long days during launches, and solving hard problems under pressure
Thrive when working on whatever is most impactful, even if that changes day-to-day based on what the production model needs
Excel at debugging complex, ambiguous problems across multiple layers of the stack
Communicate clearly and collaborate effectively, especially when coordinating across time zones or during high-stress incidents
Are passionate about the work itself and want to refine your craft as a research engineer
Care about the societal impacts of AI and responsible scaling
Strong Candidates May Also Have:
Previous experience training LLM’s or working extensively with JAX/TPU, PyTorch, or other ML frameworks at scale
Contributed to open-source LLM frameworks (e.g., open_lm, llm-foundry, mesh-transformer-jax)
Published research on model training, scaling laws, or ML systems
Experience with production ML systems, observability tools, or evaluation infrastructure
Background as a systems engineer, quant, or in other roles requiring both technical depth and operational excellence
What Makes This Role Unique:
This is not a typical research engineering role. The work is highly operational—you'll be deeply involved in keeping our production models training smoothly, which means being responsive to incidents, flexible about priorities, and comfortable with uncertainty. During launches, the team often works extended hours and may need to respond to issues on evenings and weekends.
However, this operational intensity comes with extraordinary learning opportunities. You'll gain hands-on experience with some of the largest, most sophisticated training runs in the industry. You'll work alongside world-class researchers and engineers, and the institutional knowledge you build will compound in ways that can't be easily transferred. For people who thrive on this type of work, it's uniquely rewarding.
We're building a close-knit team of people who genuinely care about doing excellent work together. If you're someone who wants to be part of training the models that will define the future of AI—and you're excited about the full reality of what that entails—we'd love to hear from you.
Location:
This role requires working in-office 5 days per week in London.
Deadline to apply:

How we're different
We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills.
The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences.
Come work with us!
Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.

Location: Lightning Labs
Workplace: Remote
Lightning Labs builds the infrastructure that makes Bitcoin work as a global payment network. Our protocols: the Lightning Network, Taproot Assets, and L402, are used by developers all around the world and are increasingly the rails that AI agents use to pay for services, stream value, and transact autonomously. We are looking for a full-stack engineer to help us build Terminal Web, the primary application node operators use to manage liquidity, channels, balances, swaps, and the rest of their Lightning operations.
Location: Fully remote, with a preference for US time zones.
THE ROLE
This is a product engineering role centered on Terminal Web. You will take features from idea to production: understanding what node operators need, designing the user flow, integrating with Lightning services, building the frontend, shaping the API layer, writing tests, and sweating the details until the feature is ready to ship. You are the person we point at a product problem and trust to come back with something that works.
Terminal Web is a TypeScript application built with Next.js, React, MobX, and Emotion. It uses server-side rendering, browser persistence, LNC-based RPCs to self-hosted litd nodes, and REST APIs to Lightning Labs services. The work spans UI, state management, API integration, data modeling, performance, reliability, and testing. The ideal candidate is comfortable moving across that stack without waiting for a narrow handoff.
We use AI-native development tools heavily. Experience using Claude Code, Codex, Cursor, or similar tools as part of your daily engineering workflow is something we are looking for directly, not a nice-to-have.
WHAT YOU'LL DO
Ship end-to-end features in Terminal Web that help users operate Lightning nodes, manage liquidity, monitor activity, and interact with Lightning Labs products through a polished browser-based application.
Build across the full stack of a modern TypeScript product: Next.js SSR, React components, MobX stores and view models, Emotion styling, IndexedDB-backed data services, LNC integrations, REST APIs, and the glue code that makes complex node operations feel simple.
Own integrations with Lightning infrastructure by working with LND, litd, Lightning Node Connect, Loop, Pool, Taproot Assets, and related services. You will translate protocol and API capabilities into clear product experiences.
Write production-quality tests with Jest and Playwright, and use those tests to move quickly without breaking the workflows node operators depend on.
Work autonomously with minimal direction. Understand company priorities, identify where you can have the most impact, collaborate with product and engineering when needed, and execute from rough problem statements through launch.
Use AI development tools as leverage for exploration, implementation, testing, refactoring, and documentation while maintaining the engineering judgment needed to ship secure, reliable software.
WHAT WE'RE LOOKING FOR
- You build and ship production-quality software. You have a portfolio, work history, or set of projects that demonstrate this, we'd love to see them.
- You have strong TypeScript and React experience, and you are comfortable with modern full-stack web application architecture.
- You have experience with server-side rendering, API clients, browser storage, state management, and the practical tradeoffs of building complex web apps for real users.
- You use AI-native development tools such as Claude Code, Codex, Cursor, or similar as part of your normal workflow, not as a novelty.
- You can take ambiguous product requirements and turn them into working software independently, while communicating clearly along the way.
- You have strong engineering practices: automated testing, code review, documentation, debugging, and a bias toward simple, maintainable designs.
- You care about product quality. You do not just wire up APIs, you think about the user, the edge cases, the loading states, and the failure modes.
- You are excited about Bitcoin, Lightning, and the mission of making Bitcoin cheap, fast, and simple for everyone.
NICE TO HAVE
- Experience building wallet, payments, fintech, infrastructure, or developer tooling products.
- Familiarity with Bitcoin, the Lightning Network, LND, litd, LNC, Taproot Assets, Loop, Pool, or related protocols.
- Experience working with WebAssembly-backed browser integrations.
- Experience with MobX, Emotion, Dexie, Bootstrap, visx, Jest, or Playwright.
- Go experience or comfort reading backend services and protobuf-defined APIs.
- Experience at a small, high-growth company where wearing many hats was the norm.

HOW TO APPLY

Over 2 million users across 130+ countries already buy, hold, and spend crypto through our app. On the B2B side, the same rails power 2,100+ platforms, with $2.4B+ moved to date.
Fully MiCA-authorized across the EEA. PCI DSS Level 2 certified. Backed by Dragonfly, TA Ventures, and Hypra.
We are an international team of young and ambitious professionals united by a passion for innovation and a belief in the decentralized world. And now, we are looking for a
Head of Crypto Vertical
who will strengthen our team and contribute to the success of our products and the bright future of Web3.
Mission:
Build and scale the crypto business line (crypto card, non-custodial wallet, trading) into an autonomous, high-growth vertical.
Own the P&L
and drive revenue, profitability, and sustainable, regulation-aware growth.
What you will do:
P&L ownership
for the crypto vertical: budgeting, forecasting, pricing, margin management.
Partnerships & BD:
identify, negotiate, and close strategic deals (issuers/processors, liquidity, payroll/HR SaaS, neobanks, exchanges, aggregators, merchants).
Market & regulation:
track competitors, user behavior, and rules (
KYC/AML/MiCA, card schemes, on/off-ramps
) and turn insights into action.
Team:
own the hiring plan and
build a lean business team from zero
(growth/performance, BD/partnerships, ops/support). Set clear responsibilities and KPIs, coach for performance, and make tough calls when someone doesn’t deliver.
Cross-functional leadership:
align Product, Legal/Compliance, Ops, Data, and Marketing around clear commercial targets and SLAs.
Reporting:
present plans, numbers, and decisions to founders/execs.
First 3–6 months (hands-on):
You’ll run ops yourself,
set up the initial processes
(pipelines, SLAs, weekly KPIs, monthly P&L), and
hire the core business team
(growth, BD, ops).
You’ll
launch acquisition channels
(target
LTV/CAC ≥ 3
in one priority segment) along with the CMO and
close the first 2–3 strategic B2B/B2B2C deals
.
Once ops are stable, you shift even more time to scaling and strategy.
Requirements:
5+ years
in fintech/crypto/payments/banking with GM / Head of BizDev / Head of Business-type ownership.
Proven
P&L
delivery on revenue, profit, margin, and volume targets.
Hands-on launching/scaling
crypto payments/wallets/cards/trading
(B2C and B2B/B2B2C).
Strong command of
unit economics
(CAC, LTV, ARPU, margin, payback), pricing, and portfolio prioritization.
Deep
partnerships/BD
track record: sourcing, negotiating, contracting, integrating, and making deals perform.
Solid grasp of
KYC/AML/MiCA
, card-scheme, and on/off-ramp constraints; productive work with Legal/Compliance.
Strong analytical skills (SQL/BI a plus) and clear executive communication in English.
What this role is not:
This is
not
a classic product manager or chief product officer role.
What we offer:
Established yet dynamic environment
: We’re a well-rooted fintech company with several profitable products and structured business units. Historically strong in B2B2C across Europe, we’re now doubling down on building and scaling a consumer-facing crypto vertical
Real traction, not just vision
: Our non-custodial wallet and crypto card are already live with confirmed product-market fit in multiple segments (with strong revenue and 6-month retention metrics). Crypto IBAN is in development, and trading is at the concept stage. There's still untapped potential in segments we haven’t entered yet.
Ownership and autonomy
: This role is essentially a mini-CEO position. You’ll have full P&L ownership, a direct line to the founders, and the mandate to build a standalone business unit with a 2+ year strategic horizon. You'll shape product offerings, growth strategy, and go-to-market channels.
Hands-on early stage, high leverage long-term
: In the first 3–6 months, you’ll build the business team (growth/BD/ops), establish processes (pipeline, SLA, KPI, P&L), and drive predictable growth via performance marketing, brand, sales, and strategic partnerships. From there, it’s all about scale and long-term impact.
Resources and support where it matters
: You’ll get the budget and resources aligned with your roadmap, autonomy in decision-making, and influence over a broader fintech product portfolio (wallet, card, IBAN, trading) in one of the most promising markets: crypto in the EU.

ABOUT US:
AI NEEDS A NEW INFRASTRUCTURE LAYER. WE'RE BUILDING IT AT MODAL.
Every era of computing brought new workloads that previous infrastructure couldn't support: mainframes, databases, and the cloud. Each time, the company that rebuilt the layer underneath defined the decade. AI is no different, except it touches everything instead of one slice, and the window to build the layer underneath it is open right now.
Our customers include category-defining companies like Ramp https://modal.com/blog/how-ramp-built-a-full-context-background-coding-agent-on-modal, Cognition, DoorDash, and Suno. They rely on Modal for instant GPU access, sub-second container starts, and native storage, so it's simple to serve low-latency inference, fine-tune models, and access production-ready sandboxes at scale.
We've passed $1B in annualized run rate, up 15x from a year ago. In October 2026 we raised a $750M Series D led by Accel at a $15.75B valuation.

We’re hiring an Enterprise Account Executive to accelerate Modal’s growth with the world’s most innovative AI companies. This is a high-impact role where you’ll own the full sales cycle—from building pipeline to closing large, strategic enterprise deals. You’ll partner directly with our founders, engineering, and product teams to help customers harness Modal’s infrastructure to train, deploy, and scale AI applications.
You’ll be expected to operate as a builder: developing new relationships, shaping our GTM motion, and serving as the voice of the customer inside Modal. The ideal candidate is both technically curious and commercially driven—equally comfortable in a room with C-level executives and with machine learning engineers. In this role, you will:
- Drive new business by generating pipeline, negotiating, and closing complex enterprise deals
- Build deep, trusted relationships with technical and executive stakeholders at leading AI companies
- Run proof-of-concepts and pilots in close collaboration with our solutions and engineering teams
- Expand existing accounts by identifying growth opportunities and helping customers scale their workloads
- Bring structured customer feedback to influence Modal’s product roadmap and GTM strategy
- Contribute to the foundation of Modal’s sales process, culture, and playbooks as we scale the team
REQUIREMENTS:
- 7–10+ years of enterprise software sales experience, ideally in infrastructure, ML/AI, or developer-focused platforms
- Track record of consistently exceeding $1M+ annual quotas and closing six- and seven-figure enterprise deals
- Strong technical acumen—able to communicate infrastructure and AI concepts with both engineers and executives
- Experience leading proof-of-concepts and managing complex procurement processes
- Excellent communication, negotiation, and relationship-building skills
- Comfortable in an early-stage, fast-moving environment; excited to help shape systems and processes from the ground up
- Ability to work in-person from our office 5 days a week
