“Every day, I build a platform here that truly makes a difference for companies and candidates. Together with the team, we solve challenging problems that are not only technically interesting but also genuinely impactful. That’s what makes working at Selection Lab so unique.”
— Rosa van der Heide, Developer
Build the engine behind fair and efficient hiring. Own our core APIs and internal data models with a pragmatic focus. Plan clearly, communicate well, and ship fast with a multidisciplinary team while strengthening our engineering culture.
About us & why join
We’re a product-first, fast-scaling HR tech company automating the selection process from careers page to first live interview. Our goal: make hiring more objective and radically more efficient. We ship fast, learn from real usage, and iterate hard.
- Fast-growing SaaS → impact measured in days, not quarters
- A great Dev team (7) → real ownership and a direct line to decisions
- Data‑informed & user‑obsessed → ship → measure → iterate
- High bar, low ego → crisp feedback, privacy‑by‑default
Role & impact
Work on backend design for reliability, performance, and security. Ship APIs/features that integrate cleanly with our Svelte frontend and external systems; use AI where it multiplies speed and quality.
- Deliver/refactor a core API/feature with clear planning & docs
- Improve perf/stability (caching, queues, requests)
- Set habits: code quality, observability, communication, optimisation
Your toolkit
Backend: Python (Flask; FastAPI/WebSockets)
Data/infra: Postgres, Redis, Docker, Heroku, AWS
Frontend: TypeScript, Svelte
DevEx: GitHub (CI/CD), typed code, pytest, Ruff, Linear, Notion, Slack
What you’ll bring
- Scale‑up ambition: bias for action, clear planning & communication, and end‑to‑end ownership.
- Team-first & T‑shaped: primarily backend, but you can jump into our TypeScript/Svelte frontend to unblock teammates, review PRs, and keep interfaces clean.
- 4–8 years backend experience in an ambitious environment. Preferably in Python or a high-level language (Go, Elixir, Rust, etc.).
- Strong API/code design, testing, and observability habits
- Security mindset & data privacy awareness
Nice to have: Flask/FastAPI, background workers/queues, Postgres, Redis, perf profiling, analytics/AI features, internationalization, devops.
A Typical Day at The Selection Lab
- Start by syncing in Linear and checking open PRs.
- Deep work on APIs, performance, or robustness.
- Lunch with the team (Friday roti is a tradition).
- Reviews & pairing to keep interfaces clean and quality high.
- More focus time to push a feature, explore a new approach or help a teammate out.
- Growth: 1:1s, learning, or short tech spikes.
- Wrap up your way (boot camp, drink, or one last PR).
