What You'll Own
Lead, coach, and grow a team of 10 full-stack developers across Node.js services and Salesforce customizations.
Drive measurable improvements in developer velocity using DORA metrics: lead time, deployment frequency, change failure rate, and MTTR.
Compress delivery schedules by breaking epics into small, independently shippable slices and challenging inflated estimates with data.
Architect end-to-end solutions spanning Node.js microservices, APIs, event-driven patterns, and Salesforce (Apex, Lightning, integrations).
Own solution performance: latency, throughput, scalability, and cost—set SLOs and hold the team accountable to them.
Establish estimation, sprint, and release discipline; remove blockers; enforce accountability without burning the team out.
Partner with Product, QA, and Infrastructure to align roadmap, capacity, and dependencies.
Recruit, onboard, and performance-manage engineers; build a culture of ownership and speed.
Requirements
10+ years in software engineering with 5+ years leading development teams of 8–20 engineers.
Deep, current hands-on experience with
Node.js
(Express/Nest, async patterns, performance tuning, microservices).
Working knowledge of the
Salesforce
platform—Apex, Lightning Web Components, Flows, REST/Platform Events, and Node.js↔Salesforce integration patterns.
Proven
technical architect
background: designed distributed systems, API contracts, data models, and performance-critical solutions in production.
Track record of
schedule compression
—case studies where you measurably reduced cycle time or pulled in release dates without sacrificing quality.
Strong estimation and planning discipline in Agile/Scrum or Kanban environments.
Experience driving
solution performance
: profiling, caching, query optimization, horizontal scaling, and observability (APM, logs, traces).
Cloud-native delivery experience (AWS preferred) with CI/CD, IaC, and modern DevOps practices.
Excellent stakeholder communication—can negotiate scope vs. time vs. quality with executives.
Success Metrics (First 6–12 Months)
Reduce average lead time for changes and increase deployment frequency to meet DORA "high" or "elite" benchmarks.
Ship the current roadmap on a compressed timeline agreed with leadership.
Improve estimate accuracy (commit vs. deliver) to within an agreed tolerance.
Meet or exceed performance SLOs for the Node.js + Salesforce solution stack.
Retain and level-up the existing team while filling any skill gaps.
Why Flosum
At Flosum, we believe great software is built by great teams—and great teams are built by leaders who care deeply about both the craft and the people. You will have the autonomy, the talent, and the mandate to build something exceptional.

HEALTH CAN’T WAIT.
Not for symptoms to get worse. Not for a six‑month appointment. Not for a system to catch up. But that’s exactly how healthcare works today. You wait, until you can’t.
Alan exists to end the wait.
Health is a universal right, and we believe this right can only become real when it’s coupled with prevention. We need to stop treating health as something we repair and start treating it as something we build, every day. It’s not solely a question of willpower. It’s the healthcare system itself that needs to work for everyone, in a sustainable way.
So we are building the new standard in prevention insurance. Alan is the first company that integrates insurance, prevention, and care into a single, acclaimed user experience.
We are on an incredible journey to build a global leading company, with a unique culture https://alan.com/en/careers. We already partner with 40K+ companies of all sizes, serving more than 1M+ members, and have reached €800M+ in ARR.
Prevention as the new norm. That's what we're building with our team of 1000+ people. If it speaks to you: we're hiring across France, Spain, Belgium, and Canada. And beyond.
⭐ BUILD THE AI-NATIVE COMPANY, FOR REAL
Alan has spent 10 years developing a distinctive way of working: radical transparency, written culture, distributed decision-making, no managers, no meetings by default. This wasn't just philosophy. It was a deliberate architectural choice, and it made Alan one of the most productive companies in European tech.
Now, agentic AI empowers us to make it much more personalized. The principles that made Alan productive become the foundation for a much more ambitious journey: a company where AI agents handle organizational complexity, surface the right context instantly, and let every person focus on the work that matters.
As a Software Engineer on this team, you will:
- Build the AI-powered internal platform that every Alaner uses daily to navigate the company, find context, and take action.
- Design and ship intelligent agents that automate real organizational workflows: onboarding, knowledge retrieval, performance alignment, decision support.
- Push LLMs into production for structured reasoning, agentic task execution, and deep integration with internal tools.
- Define the primitives and abstractions of AI-native work, the patterns that scale across every team and every country Alan operates in.
- Replace generic tools (HRIS, performance reviews, IAM) with opinionated, Alan-native software that compounds with our culture.
- Build and scale our Identity & Access Management (IAM), Privileged Access Management (PAM), and user lifecycle across 25+ systems.
- Collaborate with product, design, security and leadership to turn Alan's cultural principles into software that amplifies them.
WHY THIS ROLE IS SPECIAL
- Alan's written, transparent, async culture generates an extraordinary volume of structured organizational knowledge. Most companies can't feed AI agents with high-quality internal data. Alan already can.
- The team is building a full AI-native operational layer from scratch, not adding copilots to legacy tools.
- Every Alaner uses what you ship, every day. The feedback loop between building and impact is immediate.
- The work sits at the frontier of applied AI: agents, retrieval-augmented generation, structured outputs, tool use, human-in-the-loop design.
- The ambition goes beyond Alan. The patterns you build here could define how high-performance companies operate in the AI era.
🛠 YOUR PLAYGROUND
- Stack: Python/Flask, React, PostgreSQL, plus deep integration with LLM APIs and internal AI infrastructure.
- What you'll do: design and ship AI-native tools that power how Alan works. automated workflows, organizational navigation, agentic assistants.
- Impact: your work shapes the daily experience of every Alaner and builds the playbook for the AI-native company.
👥 WHO WE'RE LOOKING FOR
- Software engineers with +5 years of experience, ideally with backend or full-stack experience.
- Genuinely excited about AI and eager to explore what LLMs, agents, and retrieval systems can do inside a real product.
- Comfortable building in fast-moving territory where the right abstractions don't exist yet.
- Well-versed in OOP languages (Python, Java, C#) and modern web technologies.
- Fluent in English (French is a plus but not required).
- Curious, self-starting, humble, collaborative, and eager to grow.
🙌 PERKS & BENEFITS
- Fair rewards & equity packages.
- Flexible office & remote options.
- Top-tier equipment: MacBook Pro, monitor, noise-canceling headphones.
- Flexible vacation & hours.
- Comprehensive healthcare for you, children, and partners.
- Transport support and coaching for personal growth.
- Training budget for conferences, courses, books.
- Extended parental leave for all parents.
🔄 RECRUITMENT NOTE
🌟 We hire people, not roles. Don't worry if you don't check every box. High potential and curiosity matter most. We may even suggest another team if we see a better fit.

In 2026, we launched Computer, the defining product for the new era of agentic AI. Millions of people now use Perplexity to transform knowledge into action, and every action an agent takes is metered, budgeted, and settled through the billing platform this role owns.
As a monetization engineer at Perplexity, you'll own the abstractions that let product teams ship new SKUs, run pricing experiments, and convert users into paying customers, without needing to understand billing internals. The usage-based billing system this team owns is foundational to Perplexity Computer and our agentic products: metering every agent action in real time, enforcing credit budgets, and settling costs across entirely new interaction models. You'll work across subscriptions, usage-based billing, and enterprise contracts to ensure every revenue path is reliable, observable, and easy to extend.

Who We Are
At OKX, we believe that the future will be reshaped by crypto, and ultimately contribute to every individual's freedom.
OKX is a leading crypto exchange, and the developer of OKX Wallet, giving millions access to crypto trading and decentralized crypto applications (dApps). OKX is also a trusted brand by hundreds of large institutions seeking access to crypto markets. We are safe and reliable, backed by our Proof of Reserves.
Across our multiple offices globally, we are united by our core principles:
We Before Me
,
Do the Right Thing
, and
Get Things Done
. These shared values drive our culture, shape our processes, and foster a friendly, rewarding, and diverse environment for every OK-er.
About the Role
We're looking for a technical lead who can own the frontend across OKX's core crypto business verticals. You'll be deeply involved in the full frontend delivery lifecycle across Trading, Web3, Payment, and beyond — not just writing code, but helping teams and products find the right direction, make the right calls, and execute with speed and precision.
This role demands the rigor of an engineer, the strategic thinking of a product manager, and the market instincts of a crypto practitioner. You don't need to carry a full-stack title, but you must genuinely understand frontend, have enough backend fluency to hold your own in architecture discussions, and — above all — understand the business.
Core Responsibilities
Business & Team Leadership
Own the overall frontend team across core business verticals including Trading and Payment, covering hiring, development, and pipeline building. Partner effectively with Product, Backend, Security, and Compliance — driving cross-functional outcomes through technical judgment, not just execution.
Product Delivery & Technical Execution
Lead technical design and delivery for core business features including trading system frontend experience, wallet and asset management, AI-powered trading products, payment gateway integrations, and KYC/AML frontend implementation. Stay deeply sensitive to business metrics and user experience, making sound trade-offs between speed and quality.
Product & Engineering Thinking in the AI Era
Demonstrate deep understanding of how AI is reshaping product paradigms — changing user expectations, product form factors, and R&D efficiency. Integrate AI into product decisions and design, not merely as a productivity tool.
Technical Judgment & Standard-Setting
Drive tech stack alignment and evolution. Proactively identify and address technical risk. Establish high engineering quality standards in complex crypto security contexts — private key security, frontend attack prevention, compliance auditing, and more.
Cross-Team Influence
Build dual technical and business influence at the company level. Communicate technical value and business judgment clearly to engineers, product managers, and senior leadership alike. Participate in industry engagements to attract high-potential talent who are genuinely passionate about crypto.
Requirements
Bachelor's degree or above in CS or related field; 10+ years of engineering experience including 5+ years managing technical teams; solid full-stack capabilities with frontend depth
Deep command of core frontend technologies (React/Vue internals, engineering toolchains, performance optimization, cross-platform solutions), with enough backend and API fluency to drive substantive technical discussions
Proven track record leading frontend for products with DAU 1M+ in high-concurrency, high-availability environments
Demonstrated experience driving cross-team collaboration and standard adoption through technical influence rather than organizational authority
Industry Background (Partial Core)
(Core)
Genuine understanding of and enthusiasm for crypto — familiar with CEX/DEX trading mechanics, Web3 wallet and signing mechanisms, and mainstream payment gateway ecosystems
Experience owning frontend delivery for trading, fintech, payments, or crypto products; comfortable navigating the tensions between compliance, security, and user experience
Familiarity with the Web3 frontend ecosystem (ethers.js / wagmi / viem, WalletConnect, EVM contract interactions, etc.)
Global product experience — understands the complexity of multi-language, multi-currency, multi-jurisdiction compliance requirements
Engineering Competencies for the AI Era (Core)
Deep understanding of how AI is reshaping product design; can integrate AI into product decisions rather than treating it purely as a development accelerator
Strong ability to model and frame complex problems; defines the right problem boundaries and system abstractions before reaching for solutions
Proven ability to constrain, guide, and evaluate AI outputs — decomposing complex engineering requirements into AI-executable task sequences
Experience establishing team-level AI working patterns; familiar with and having practiced AI Spec-Driven Development
Maintains high standards for code quality and system design integrity alongside — not despite — AI-assisted development
Soft Skills (Core)
Strong ownership: treats team goals as personal goals — proactive, accountable, clears obstacles without being asked
Sound judgment: makes high-quality decisions under incomplete information — decisive and accountable
Execution muscle: makes things actually land, not just live in decks and proposals
Fast learner: thrives in a fast-moving industry; rapidly absorbs new technologies, business dynamics, and regulatory shifts and converts them into team action
Bilingual: fluent English for technical discussions, documentation, and international collaboration (written and verbal at working proficiency)
