Software Engineer, PhysicsX

• A passion for the craft of software engineering and building robust, maintainable systems in a collaborative, cross-functional team
• Solid software engineering skills, with a focus on writing clean, testable, and maintainable code
• A commitment to owning the software development lifecycle, including testing, containerization, and CI/CD
• Expert-level proficiency in modern Python, with a deep understanding of its performance characteristics, design patterns, and packaging
• Familiarity with building performant and reliable Python systems, including low-level C/C++ extensions (e.g., using pybind11, Cython) and instrumentation for production telemetry (e.g., Prometheus, OpenTelemetry)
• A proactive ownership mindset and the ability to navigate ambiguity
• Excellent collaboration and communication skills for working effectively with teams and stakeholders

Desirable

• PhysicsX is developing a platform used by Data Scientists and Simulation Engineers to build, train and deploy Deep Physics Models
• The core of this platform is powered by several Machine Learning Python Libraries handling everything from data processing, to deep learning model training, and complex optimisation algorithms
• The Libraries team is responsible for designing, developing, and maintaining those Machine Learning Libraries
• As a Software Engineer within the team, you will focus on the underlying engineering that makes our libraries fast, scalable, and a pleasure to use
• You are a software craftsperson who champions best practices, ensuring that our entire development lifecycle—from code design to CI/CD—is robust and maintainable
• Your work provides the solid foundation upon which our machine learning innovations are built
• Collaborate with product managers, machine learning engineers, and library users to translate functional requirements into robust technical specifications and production-ready code code
• Architect, build, and maintain the foundational software of our internal Machine Learning libraries, with a relentless focus on performance, and scalability
• Contribute high-quality, tested, documented, and maintainable code across the library stack, ensuring our core systems are reliable and easy for other engineers to build upon
• Champion software engineering excellence across the team and company, driving best practices in testing (unit, integration, performance), CI/CD, and system architecture
• Own your work end-to-end, from ideation and experimentation through to deployment and maintenance in a small, agile team environment
• Continuously explore and evaluate new techniques and frameworks, helping to guide the technical evolution of our platform
• Share your knowledge with the team, contribute to our engineering guild, and stay connected with the broader community
