Lead Software Engineer

Write code that shapes what happens on track. Atlassian Williams F1 Team is looking for a Lead Software Engineer to join our Performance Technology group. 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           What we're looking for 10+ years of software development experience, with at least 2 years in a senior or lead engineering role Comfort working across the full stack, including performance-critical low-level code in C++ or Rust, as well as Python for data analysis and exploratory workflows Strong architectural knowledge across distributed systems, real-time streaming technologies (Kafka, WebSockets), and data persistence strategies spanning relational, document, and time-series stores Familiarity with or genuine curiosity around functional programming, including languages such as F# A proven track record designing and delivering scalable, maintainable systems with end-to-end technical ownership A pragmatic, outcome-driven approach with a strong desire to engage directly with users and stakeholders Experience with modern DevOps practices including CI/CD, containerisation, and infrastructure-as-code   Nice to have A degree in Computer Science, Engineering,…
