Think it, build it, ship it, tweak it - that’s our rhythm. Spotify’s Confidence team is a startup inside Spotify, building the next‑generation experimentation platform used by hundreds of internal teams - and now being prepared for external customers. You’ll join a small, senior crew of backend, data, and research engineers who care deeply about correctness, performance, and design. We move fast and carefully: ship small, reversible changes with strong safeguards, measure impact, and iterate. We operate multi‑tenant, high‑scale services where reliability and developer experience are first‑class. You’ll build, run, and refine these systems end‑to‑end, partnering with Product, Data Science, and our Customer Success team to turn real‑world signals into product improvements. We keep process light and hold a high bar for ownership and impact.
