Lead – Software Engineer (Devex)

Company: ON RUNNING
Apply for the Lead – Software Engineer (Devex)
Location: London
Job Description:

We are looking for a Senior or Lead Software Engineer to join the Developer Experience (DevEx) team. In this hands‑on IC role, you will help to build the platform that empowers dozens of technology teams to build, ship, and operate services effortlessly. You will be involved in building and architecting our “Golden Path,” ensuring that speed, safety, and reliability are baked into every developer’s workflow.

Your story

  • Product Thinking: You treat internal developers as your customers. You listen to their pain points and iterate on the platform based on real‑world feedback.
  • Infrastructure as Code: You are comfortable with Terraform and Kubernetes (GCP experience is a plus), treating infrastructure with the same rigor as application code.
  • Automation Mindset: You are passionate about CI/CD (GitHub Actions) and building developer tooling (CLIs, SDKs, or Portals).
  • AI‑Augmented Engineering Workflows: You leverage (or have an active interest in) the latest agentic coding tools to 10x your productivity, blending deep technical principles with AI‑assisted workflows. As a power user of AI, you orchestrate complex builds and bypass boilerplate to deliver robust, scalable code at pace, ensuring our TypeScript/Node.js environment remains lean and efficient (other tech‑stacks are acceptable).
  • Architectural API Design: Tangible experience in crafting robust API contracts with a focus on GraphQL Federation; familiarity with the Apollo tech stack is highly regarded.
  • Data‑Driven: You understand DORA metrics and DevEx signals, using them to measure the success of the tools you build.

What Success Looks Like

  • Velocity: A measurable reduction in lead time for new services reaching production.
  • Autonomy: Product teams can provision infrastructure and deploy APIs independently using your self‑service tools.
  • Stability: High adoption of standardised “Golden Path” templates, leading to fewer production incidents and faster MTTR.
  • Satisfaction: High internal Developer Satisfaction (DevEx) scores and positive feedback on the tooling you maintain.
  • Team Spirit: You thrive in a high‑performing “sports team” culture, contributing to the power of the whole through consistent teamwork and earned leadership.
