Who you are
- 8+ years in software engineering with a track record of building internal developer tooling/DevEx (CLI/IDE plugins, bots, internal services or web apps)
- Strong proficiency in TypeScript/Node.js, C#/.NET and front-end experience with React/Next.js
- Hands-on LLM integration: prompting, tool/function calling, retrieval (embeddings/vector stores) and basic evaluation of quality
- Solid understanding of CI/CD, test strategy and code-quality tooling; able to design fast inner loops and reliable pipelines
- Product mindset: discovery interviews, hypothesis-driven experiments, before/after evaluation and clear business cases
- Excellent communication and influence skills; comfortable enabling teams via docs, workshops and remote office hours
- A role model for our values:
- Make it happen
- Succeed together
- Be the customer
- Go beyond
Desirable
- Experience administering/rolling out AI coding tools (Copilot, Cursor) and code search
- Familiarity with structured/agentic AI workflow frameworks for multi-step tasks
- Observability for developer platforms (metrics, tracing, dashboards) and performance tuning of AI workloads
- Evaluation techniques for LLM output quality (human-in-the-loop, rubric scoring, golden datasets)
- Experience with GitHub, Slack, Notion and Retool
- Background in fintech/payments or other regulated domains
What the job involves
- This is a staff-level, hands-on role at the intersection of Developer Productivity, Developer Experience (DevEx) and AI
- You’ll accelerate a 100+ engineer organisation by identifying bottlenecks across the developer lifecycle and build and ship internal tools that measurably improve delivery speed and quality
- You’ll operate with an AI-first mindset: rapidly experiment with cutting-edge AI technologies and agentic flows to see what’s possible today, map the frontier and forecast capabilities likely to become viable in the next 3-6 months
- When AI isn’t the right fit, you’ll pragmatically fall back to conventional solutions
- You’ll self-manage discovery, roadmap and backlog; run short, data-driven trials and productionise solutions which work
- You’ll partner closely with Engineering and DevOps teams to ensure changes integrate cleanly into existing workflows
- AI-first discovery roadmap – Interview engineers, analyse telemetry and prioritise the highest-leverage opportunities across coding, review, testing, releases and knowledge flows
- Set baselines and target deltas and maintain a transparent backlog/roadmap grounded in measurable outcomes
- Ship internal tools – Build and maintain AI-augmented dev tools across IDE/CLI, GitHub, Slack, Notion, Retool and internal web apps that reduce manual effort and cycle time
- Agentic flows across the SDLC – Design structured, agentic workflows (including MCP and tool-use with human-in-the-loop gates) to improve code authoring/review, test creation/selection and the release, incident response and onboarding processes
- Frontier scouting & evaluation – Continuously experiment with cutting-edge AI models, frameworks and runtimes; run short, hypothesis-driven pilots with clear success criteria and developer-fit assessments; productionise successful approaches
- Automation pipelines – Implement LLM-assisted and AST-based code-mod workflows for migrations, boilerplate generation, test creation and docs updates
- Enablement & change management – Drive adoption with playbooks, golden prompts, demos, office hours and a champions network across build teams; measure usage and satisfaction and iterate
- Measurable impact – Reduced cycle time for new features
- Quality & reliability – Improved stability; fewer defects and incidents attributable to code changes
- Adoption & enablement – Growth in weekly active users of AI and other dev tools; strong satisfaction with guidance, prompts and enablement materials
- Developer satisfaction – Higher engineer NPS and engagement
- Operational excellence – Well-maintained internal tools with monitoring, docs and responsive support; clear deprecation paths for experiments that don’t meet the bar
