Software Engineer TypeScript

About this role

## Why we exist

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 TypeScript.

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.

• Help evolve our infrastructure on AWS (SST/Pulumi, PostgreSQL on Neon, GitHub Actions) as the platform scales.
