The Role
About us
Note: We are currently recruiting for multiple positions, however please only apply for the role that best aligns with your skillset and career goals.What you will do PhysicsX is a deep-tech company with roots in numerical physics and Formula One, dedicated to accelerating hardware innovation at the speed of software.
We are building an AI-driven simulation software stack for engineering and manufacturing across advanced industries. By enabling high-fidelity, multi-physics simulation through AI inference across the entire engineering lifecycle, PhysicsX unlocks new levels of optimization and automation in design, manufacturing, and operations — empowering engineers to push the boundaries of possibility. Our customers include leading innovators in Aerospace & Defense, Materials, Energy, Semiconductors, and Automotive.
- Work closely with our research scientists and simulation engineers to build and deliver models that address real-world physics and engineering problems.
- Design, build and optimise machine learning models with a focus on scalability and efficiency in our application domain.
- Transform prototype model implementations to robust and optimised implementations.
- Implement distributed training architectures (e.g., data parallelism, parameter server, etc.) for multi-node/multi-GPU training and explore federated learning capacity using cloud (e.g., AWS, Azure, GCP) and on-premise services.
- Work with research scientists to design, build and scale foundation models for science and engineering; helping to scale and optimise model training to large data and multi-GPU cloud compute.
- Identify the best libraries, frameworks and tools for our modelling efforts to set us up for success.
- Own Research work-streams at different levels, depending on seniority.
- Discuss the results and implications of your work with colleagues and customers, especially how these results can address real-world problems.
- Work at the intersection of data science and software engineering to translate the results of our Research into re-usable libraries, tooling and products.
- Foster a nurturing environment for colleagues with less experience in ML / Engineering for them to grow and you to mentor.
What you bring to the table
- Enthusiasm about developing machine learning solutions, especially deep learning and/or probabilistic methods, and associated supporting software solutions for science and engineering.
- Ability to work autonomously and scope and effectively deliver projects across a variety of domains.
- Strong problem-solving skills and the ability to analyse issues, identify causes, and recommend solutions quickly.
- Excellent collaboration and communication skills — with teams and customers alike.
- MSc or PhD in computer science, machine learning, applied statistics, mathematics, physics, engineering, software engineering, or a related field, with a record of experience in any of the following:
- Scientific computing;
- High-performance computing (CPU / GPU clusters);
- Parallelised / distributed training for large / foundation models.
- Ideally >1 years of experience in a data-driven role, with exposure to:
- scaling and optimising ML models, training and serving foundation models at scale (federated learning a bonus);
- distributed computing frameworks (e.g., Spark, Dask) and high-performance computing frameworks (MPI, OpenMP, CUDA, Triton);
- cloud computing (on hyper-scaler platforms, e.g., AWS, Azure, GCP);
- building machine learning models and pipelines in Python, using common libraries and frameworks (e.g., NumPy, SciPy, Pandas, PyTorch, JAX), especially including deep learning applications;
- C/C++ for computer vision, geometry processing, or scientific computing;
- software engineering concepts and best practices (e.g., versioning, testing, CI/CD, API design, MLOps);
- container-ization and orchestration (Docker, Kubernetes, Slurm);
- writing pipelines and experiment environments, including running experiments in pipelines in a systematic way.
- Equity options – share in our success and growth.
- 10% employer pension contribution – invest in your future.
- Free office lunches – great food to fuel your workdays.
- Flexible working – balance your work and life in a way that works for you.
- Hybrid setup – enjoy our new Shoreditch office while keeping remote flexibility.
- Enhanced parental leave – support for life’s biggest milestones.
- Private healthcare – comprehensive coverage
- Personal development – access learning and training to help you grow.
- Work from anywhere – extend your remote setup to enjoy the sun or reconnect with loved ones.
