Developer Experience Engineer (Dev Ex / DX) – Platform team. This founding individual contributor role can be based in any UK office (London, Manchester or Bath). We are looking for someone who can build a Dev Ex function from the ground up, accelerate developer productivity, and remove engineering friction across the organisation.

• Lead the evaluation and integration of developer tools, especially AI‑assisted development tooling; support team adoption by sharing knowledge, running demos, tracking utilisation and demonstrating value.
• Experiment with emerging developer tooling and evaluate their real‑world impact on engineering productivity.
• Develop and maintain "golden path" templates and scaffolding to accelerate project bootstrapping and promote consistent engineering practices.
• Improve and standardise the local development experience across all engineering teams (environment setup, local services, test data, etc.) to reduce onboarding and iteration time.
• Work with the Platform Engineering department to securely abstract infrastructure and cloud tasks away from software engineers.
• Assess and recommend improvements to CI/CD pipelines and SDLC processes; reduce build and test feedback loops by improving CI pipeline performance and reliability.
• Define and track developer productivity metrics (build times, CI performance, deployment frequency) to identify systemic friction and measure improvement.
• Help software teams curate high‑quality pipelines and tests, ensuring high release confidence.
• Build and maintain internal developer tools (CLIs, automations, shared libraries, etc.) that simplify common engineering workflows.
• Conduct regular user research and feedback sessions with engineering teams to identify friction points and propose improvements.
• Improve the structure and discoverability of engineering documentation, reducing time‑to‑first‑MR and improving engineering onboarding.

• 4+ years of experience in Software Engineering, Dev Ex, and/or Platform Engineering roles.
• Strong proficiency in at least one modern systems or scripting language (ideally Go).
• Demonstrated experience integrating generative AI‑powered tooling into software workflows.
• Understanding of the limitations, failure modes, and security risks associated with LLMs (hallucinations, prompt injection, context window limits, etc.).
• Deep understanding of the modern SDLC, including Git flow, CI/CD (especially Git Lab CI), and containerisation technologies (Docker, Kubernetes).
• Exceptional empathy for the developer experience; a product mindset where the "customer" is the internal software engineer.
• Understanding of the developer mindset to ensure enthusiastic adoption of new tools and practices.
• Strong written communication skills, with the ability to write documentation that is easily parsable by both humans and LLMs.
• Ability to navigate ambiguity and define standards in a rapidly evolving technology landscape.
• Awareness of cost implications in a cloud environment and methods of optimising services for maximum ROI.

• Experience building or coordinating autonomous agents that can perform multi‑step engineering tasks (agentic workflows).
• Experience with Backstage.io or other developer portals.

• Developer tools:
  Cursor, Claude, Codex, Jet Brains (IntelliJ/GoLand).
• CI/CD:
  Git Lab Premium (self‑hosted).
• Backend:
  Typescript, tRPC, Go, OpenAPI, RabbitMQ, MariaDB.
• Infrastructure:
  Terraform/Open Tofu, Kubernetes, Docker, AWS, Puppet, Rocky Linux.
• DORA metrics:
  Sleuth.

• 33days annual leave (includes public holidays, which can be worked if you prefer).
• Generously enhanced family leave and pay.
• Enhanced sick pay from day1, rising to 12weeks full pay after6months.
• Salary‑sacrifice pension with matched employer contributions up to 5% + NI savings.
• Private health…
