About the Role and How We Work

I’m Colin, Head of EMEA Engineering, and I’ve led engineering teams in startups for many years. Our infrastructure is mission‑critical and continuously evolving. As a Platform Engineer at Ashby you will own end‑to‑end projects, ship code with minimal oversight, and maintain a secure, simple environment for our product‑team to build in.

Responsibilities

Qualifications

• Strong coding skills and a passion for building engineered solutions.
• Experience building or maintaining large‑scale distributed systems.

• A mindset that values security, reliability, and high performance.

Why You Should or Shouldn’t Apply

• Apply if you enjoy deep problem solving, taking ownership, and writing impact‑driven code.
