Technical Lead – Developer Experience, DevEx

Role Overview

• Define and guide the architecture of internal developer tools and services, specifically assessing, integrating, and maintaining AI-powered tools (e.g., agents, agentic environments, coding assistants, diagnostic tools), balancing trade-offs between speed of development, reliability, and maintainability to meet engineering efficiency goals.
• Own and evolve the organisation's agentic AI working practices across R&D — defining standard skills, instructions, agent configurations, and interaction patterns that enable every engineer to work effectively with AI tooling.
• Champion developer productivity by identifying and addressing pain points in the development lifecycle. Measure key internal metrics (e.g., build times, deployment cycle time) and drive continuous improvement in developer workflows and tooling.
• Drive automation initiatives, leveraging agentic AI and machine learning techniques, across the team to streamline developer onboarding, reduce cognitive load, and eliminate development environment toil.
• Define and uphold developer experience standards, promote clear documentation, and work with teams to ensure seamless adoption of new technologies and best practices.
• Lead technical estimation and feasibility assessments for DX initiatives, ensuring plans are realistic and aligned with team capacity.
• Mentor and coach engineers through constructive feedback, knowledge sharing, and motivation. Foster alignment and help the team galvanise around technical solutions and goals.
• Work closely with Product Managers, Engineering Managers, and other engineers to gather feedback, understand developer pain points, and align technical direction with product strategy.

Requirements

• Considerable experience in Developer Relations, Developer Productivity, or building internal tooling on complex systems.
• Proven experience integrating and leveraging AI, machine learning, or generative AI tools (e.g., Cursor, Claude Code, Coder) to significantly improve developer workflows, accelerate feature delivery, and increase overall engineering efficiency.
• Extensive expertise with AWS and distributed cloud architectures for building developer-facing services.
• Proven experience with measuring and optimizing engineering efficiency metrics and reducing deployment friction.
• Advanced proficiency with Terraform and configuration management tools for managing developer environments.
• Strong skills in Python, Go, or a similar language for automation and tooling.
• Experience in PHP, or another language; preferably in a significantly sized Object Orientated codebase.
• Deep experience with monitoring and observability platforms (e.g., DataDog or equivalent), focusing on gathering insights into developer friction points and incident/problem management.
• Expert understanding of distributed systems and microservices and how to apply resilience patterns to internal tools.
• Hands-on experience with containerization and orchestration technologies (Docker, Kubernetes, ECS) for creating standardized development environments.
• Practical experience with building and maintaining CI/CD pipelines to ensure a smooth deployment experience for other engineers.
• Demonstrated ability in mentoring and supporting the growth of fellow engineers, experience organising and driving team workstreams.
