Warren is a workplace pension and financial coaching platform that combines AI-powered guidance with human advisers and manages its own pension fund.
WHY WARREN EXISTS Most compensation plans in Belgium lag behind: low-yield products, no transparency, endless paperwork. Employees worry about financial security while HR teams drown in admin. Warren is redefining the landscape with Wealth Enablement — a new category making pensions, benefits, and investing modern, transparent, and truly valued. Our entire platform runs on TypeScript, bringing the future of financial products to the present. We're growing fast, and as a junior joining now, you'll get to build real product experience early — with the support to grow quickly rather than being thrown in the deep end. WHAT YOU'LL OWN We're hiring a Junior Software Engineer for our growing Engineering team. You'll work closely with a senior engineer or mentor as you ramp up, taking on increasing ownership of features as you build context — collaborating with product, design, and other engineers along the way. DAY-TO-DAY RESPONSIBILITIES 1. Ship Product That Matters - Build and deliver features for backend, web, or mobile that improve user financial wellbeing, with support from senior engineers on scoping and review. - Take ownership of well-defined pieces of a feature — implementation, testing, and monitoring — with guidance on discovery and production concerns as you grow into them. - Work on a high-impact, category-defining product with genuine market traction. 2. Grow Across the Stack - Contribute to frontend (React, React Native, Tailwind, shadcn/ui) and/or backend (NestJS, Hono, Drizzle ORM) depending on your strengths and interests, with room to expand over time. - Write clean, maintainable, type-safe TypeScript code, with feedback from experienced teammates via code review. - Get hands-on exposure to our AWS-based infrastructure (SST/Pulumi, PostgreSQL on Neon, GitHub Actions) alongside engineers who own it. 3. Learn and Contribute to Engineering Culture - Participate actively in code reviews and architectural discussions — as a learner first, contributor as you gain footing. - Absorb and start applying team engineering standards and best practices. - Build security-conscious habits when working with sensitive financial data, with guidance from senior engineers on what matters most. 4. Work With a Modern Stack - Monorepo with pnpm workspaces and Turborepo. - Frontend: React, React Native, TypeScript, Vite, Tailwind, shadcn/ui. - Backend: NestJS, Drizzle ORM, Hono, vitest, bun. - Infrastructure: SST/Pulumi on AWS, GitHub Actions, PostgreSQL on Neon. - Collaboration tools: Linear, Slack, Notion, GitHub, Sentry, Cursor, Claude Code, CodeRabbit. - Engineering principles: reusable primitives, strict type safety, clean code, and cooldown weeks. ABOUT YOU - Master's degree in Computer Science. - Comfortable with AI-assisted coding tools and eager to use them well. - A first experience with software engineering (internship, thesis project, or first job) — you don't need years of production experience. - Proficient in, or quick to pick up, TypeScript; excited to work across the stack over time. - Some experience with React, React Native, Node.js, or similar frameworks. - Basic familiarity with relational databases (PostgreSQL); cloud infrastructure exposure is a bonus, not a requirement. - Care about writing clean, simple code and are eager to build good habits around code quality. - Curious and thoughtful about security, especially with sensitive financial data — we'll help you build the instincts. - Strong communicator who's comfortable in a collaborative, fast-paced, English-speaking team, and not afraid to ask questions. - Bonus: exposure to fintech, financial services, infrastructure as code, open-source, or side projects at any scale. If you're early in your career but passionate about building real products and care about outcomes as much as code quality, Warren wants to help you grow into that.
