This is a rare opportunity to lead a team of engineers building bespoke, high-performance software that directly supports our Aerodynamics, Vehicle Dynamics, and Vehicle Performance functions. At Williams, software and data are central to our mission of advancing up the grid, and this role puts you at the heart of both. The Role You'll lead a team of 3-5 engineers, taking ownership of technical direction, architecture, and delivery across a diverse and sophisticated software estate. From real-time data systems and state-of-the-art simulations to bespoke analysis tools and cloud-native modernisation, the problems you'll solve are genuinely complex and genuinely consequential. You'll remain hands-on, contributing directly to design and code while setting the technical standard for those around you. Our stack is deliberately broad: desktop applications in C++ and C#, web applications in React/TypeScript, Python-based analysis tools, and backend services in C++, Rust, F#, and C#. We use the right tool for the right job, and we're on an exciting journey adopting cloud-native technologies and modern data platforms. What you'll be doing * Leading the technical direction of your team: making architectural decisions, choosing frameworks and patterns, and setting quality standards through code review and hands-on contribution * Mentoring and developing your engineers through coaching, knowledge sharing, and regular feedback * Managing technical dependencies and risks across concurrent projects, balancing feature delivery against technical debt * Acting as the bridge between engineering and the performance functions you support, translating their problems into deliverable software * Contributing to technology strategy across Performance Technology and the wider software group ## Related Videos - [Minimal infrastructure for Real‑Time Phone Agents: transcripts in, responses out](https://www.wearedevelopers.com/videos/1736-minimal-infrastructure-for-real-time-phone-agents-transcripts-in-responses-out) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [The AI-Native Engineering Org: What’s Real, What’s Hype, What’s Next](https://www.wearedevelopers.com/videos/100004-the-ai-native-engineering-org-what-s-real-what-s-hype-what-s-next) - [Leveraging Server-Sent Events (SSE) for Efficient Data Streaming in UI Development](https://www.wearedevelopers.com/videos/905-leveraging-server-sent-events-sse-for-efficient-data-streaming-in-ui-development) - [How Sparking Developer Joy Unlocks Developer Productivity](https://www.wearedevelopers.com/videos/613-how-sparking-developer-joy-unlocks-developer-productivity) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [The Best Software Developer Blogs to Read](https://www.wearedevelopers.com/magazine/156-the-best-software-developer-blogs-to-read) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers)
