Backend Engineer – AI Tech Scale-up (Python / Go / Elixir / Rust)
Do you get energy from working in a start-up environment where every line of code has impact? Do you want to take real ownership of the core systems in a fast-growing AI platform — not just tickets handed down from above?
Here’s your chance to help scale a product that is changing how companies select and hire talent.
Bedrijfsprofiel
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.
