Backend Engineer – AI Tech Scale-up (Python / Go / Elixir / Rust)

Company profile

Our client is a rapidly growing HR-tech scale-up in Amsterdam, building an AI-driven selection engine that automates prescreening, assessments and scheduling. Backed by strong funding and trusted by European customers, they are scaling fast.

The setup is pure start-up mode: a small engineering team (4 people, soon 5+), no middle management, short lines, and a culture that thrives on drive, learning and speed. You’ll see the results of your work live within days — not months.

This is not the place for 9–5 routines. It’s the place for engineers who love building, experimenting and growing together in a team that takes pride in shipping.
