Software Engineer; TypeScript

Software Engineer Type Script

Build a category‑defining product from the ground up. We're hiring across multiple levels and across the stack.

Location:

Belgium (hybrid, Ghent) or fully remote.

Most compensation plans in Belgium are stuck in the past: low‑yield products, low transparency, endless paperwork. Meanwhile, employees are stressed about money and HR teams are buried in admin.

That's where WARREN comes in. We're pioneering Wealth Enablement: a new category that makes pension, benefits and investing modern, transparent, and genuinely valued. The entire platform is 100% powered by Type Script.

We're defining a new category, we're hugely ambitious, and momentum is building fast. The decisions you make now will shape the product and the engineering culture for years to come.

We're hiring software engineers at all levels and across the stack: frontend, backend, mobile, full stack, platform, and product‑minded engineers who want to own what they build.

As a product engineer, you'll work closely with internal stakeholders, product and design to understand scope and requirements, then build features and ship with end‑to‑end ownership.

If you want to learn more, move faster and have more fun than anywhere else, keep reading.

• Build and ship features across backend, web and mobile platforms that delight users and improve their financial lives.
• Own features end‑to‑end: from understanding the problem with product and design, through implementation, to monitoring in production.
• Work on a category‑defining product with a huge market opportunity and real initial traction.

• Contribute to frontend (React, React Native, Tailwind, shadcn/ui), backend (NestJS, Hono, Drizzle ORM), or both, depending on where you're strongest and what you want to grow into.
• Write clean, simple, readable, maintainable, type‑safe Type Script across the entire codebase.
• Help evolve our infrastructure on AWS (SST/Pulumi, PostgreSQL on Neon, Git Hub Actions) as the platform scales.

• Participate in code reviews, architectural decisions, and internal platform initiatives.
• Help set the standards of an engineering culture people can be proud of for many years to come.
• Share knowledge, mentor teammates, and contribute to best practices across the team.
• Bring a security mindset to safeguard sensitive financial customer data.

• Monorepo using pnpm work spaces and Turborepo.
• Frontend:
  React, React Native, Type Script, Vite, Tailwind, shadcn/ui.
• Backend:
  NestJS, Drizzle ORM, Hono, vitest, bun.
• Infrastructure: SST/Pulumi on AWS, Git Hub Actions, PostgreSQL on Neon.
• Collaboration:
  
  Linear, Slack, Notion, Git Hub, Sentry, Cursor, Claude Code, Code Rabbit.
• Principles: reusable primitives, strict type safety, clean code, and yes, cooldown weeks.

We're looking for engineers at every career stage. What matters most is that you care about your craft, you ship with ownership, and you want to build something that matters.

• You have strong proficiency in Type Script (or are demonstrably fast at picking it up) and genuine enthusiasm for working across the full stack.
• You've built things with React, React Native, Node.js, or similar modern frameworks. The specific combination matters less than your ability to learn and adapt.
• You're comfortable with relational databases (PostgreSQL) and have some exposure to cloud infrastructure.
• You write clean, simple, type‑safe code and care about code quality without being dogmatic about it.
• You have a security mindset, especially important when handling sensitive financial data.
• You're a strong communicator who thrives in a collaborative, fast‑moving team.
• You're fluent in English (written and spoken).
• Bonus points:
  
  fintech or financial services experience, infrastructure as code (SST), open‑source contributions, consumer apps at scale.

Most importantly: you want to build something real, not just write code. If you care about the outcome as much as the implementation, you belong here.

• Product thinking: we build for user outcomes, not for feature count.
• Ownership: real say in decisions, real stock options, real chance to leave a mark.
• Growth: stretch your brain, share your thoughts, and level up faster than you thought possible.
• Flexibility: work when, where, and how you do your best, with the tools you choose.
• Team: smart, passionate, entrepreneurial, and occasionally meme‑driven.
• Stack: modern Type Script end‑to‑end, cooldown weeks, and an obsession with developer experience.

Send us a short note at careers telling us:

• What kind of engineer you are and where you're strongest today.
• Something you've built that you're proud of: at work, in open source, or on the side.
• Why Warren, and what excites you about building in fintech.
