Junior Software Developer jobs in United States

At Atlassian Williams Racing, we’re seeking a Senior Software Engineer with a proven track record of solving difficult technical problems. You will have experience building scalable and performant systems, balancing short term incremental wins against long term architectural improvements.

This is a hands-on role focused on enabling cutting-edge simulation, modelling, and real-time analysis systems critical to our competitive edge in Formula 1. You’ll work with a highly specialized user base including race engineers, vehicle dynamics engineers, and performance analysts, helping to design and optimize software that powers everything from vehicle simulations to trackside decision-making tools.

We believe data and compute-intensive software are core to our performance evolution, and your work will help us move faster and smarter, both virtually and physically.

• Designing and implementing high-performance software components for simulation, data analysis, and operational decision support
• Extending existing codebases and building new tools that scale with complex engineering workloads
• Contributing to our real-time data infrastructure, including protocols for low-latency messaging and efficient data serialisation
• Mentoring developers and promoting software engineering best practices in a high-integrity, performance-critical environment
• Collaborating with domain experts to encode physical models, algorithms, and workflows into robust, maintainable code

We use the right tool for the job. Our current stack includes:

• C++, Rust and F# for high-performance desktop and backend applications
• Typescript/React for web-based UIs
• Python for analysis, tooling, and rapid prototyping
• Cloud-native services (Azure, Docker, Kubernetes) alongside HPC and on-prem systems
• Data transport via WebSockets, TCP, and custom protocols for real-time telemetry and control

• A degree in Computer Science, Engineering, Physics, Applied Mathematics or similar
• Experience of software development, testing, and CI in languages such as C++, Rust or F#, built upon a solid foundation in computing fundamentals – OS, CPUs, memory, networking
• A problem solving and adaptable mindset, a curiosity to understand how things work, and enthusiasm to learn new techniques and technologies.
• A passion for performance profiling, debugging, and squeezing the most out of CPU and memory
• Ability to work closely with engineers to translate complex requirements into well-structured software
• A track record of driving technical decision making, bringing fresh insight and perspective on problems

• Familiarity with time series databases or streaming telemetry platforms
• Interest or background in functional programming (e.g. F#, Haskell) or applying FP principles in hybrid environments
• Exposure to low-latency, real-time systems or embedded software
• Experience building or maintaining applications in simulation, optimization, signal processing, or related domains
• Domain experience in motorsport, aerospace, or similar high-performance industries

This is a rare opportunity to push the limits of engineering software in one of the world’s most competitive environments. If you're driven by technical excellence and excited by the challenge of solving physics-driven problems at speed, we want to hear from you.

For almost 50 years, Williams Racing has been at the forefront of one of the fastest sports on the planet, being one of the top three most successful teams in history competing in the FIA Formula 1 World Championship. With an almost unrivalled heritage of engineering and racing F1 cars and unforgettable eras that demonstrate it is a force to be reckoned with, the British squad boasts 16 F1 World Championship titles to its name.

Since its foundation in 1977 by the eminent, late Sir Frank Williams and engineering pioneer Sir Patrick Head, the team has won nine Constructors’ Championships, in association with Cosworth, Honda and Renault. Its roll call of drivers is legendary, with its seven Drivers’ Championship trophies being lifted by true icons of the sport: Alan Jones, Keke Rosberg, Nelson Piquet, Nigel Mansell, Alain Prost, Damon Hill and Jacques Villeneuve. The team has made history before and is out to make it again with a long-term mission to evolve and return to the front of the grid.

Atlassian Williams Racing is an equal opportunity employer that values diversity and inclusion. We are happy to discuss reasonable job adjustments.
