About us
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.
Note: We are currently recruiting for multiple levels and positions, however please only apply for the role that best aligns with your skillset and career goals.
What you will do
- Own Research work-streams at a high-level to deliver outcomes.
- Align priorities with problem stakeholders, internal and external.
- Set the technical direction for the stream and apply judgement and taste to drive progress.
- Plan roadmaps with clear milestones for key decisions and outcomes.
- Organise and guide the more junior members of the team to effectively execute and deliver against this roadmap.
- Communicate purpose and key outcomes to raise awareness across the company and create opportunities for use and deployment.
- Contribute towards Research group strategy and culture.
- Identify research areas that would be valuable to the company and champion their development, ordering wrt other research objectives.
- Promote effective working patterns and proactively flag issues with team dynamics to foster a productive environment.
- Nurture younger colleagues to grow their skillset and guide their professional development.
- The below activities in particular.
- Work closely with our machine learning engineers, simulation engineers, and customers to translate physics and engineering challenges into mathematical problem formulations.
- Build models to predict the behaviour of physical systems using state-of-the-art machine learning and deep learning techniques.
- Discuss the results and implications of your work with colleagues and customers, especially how these results can address real-world problems.
- Collaborate with colleagues beyond the research team to translate your models into production-ready code.
- Communicate your work to others internally and externally as called for in paper publication venues, industry workshops, customer conversations, etc. This will involve writing for academic and non-academic audiences.
What you bring to the table
- Ability to scope and effectively deliver projects.
- Enthusiasm about using machine learning, especially deep learning and/or probabilistic methods, for science and engineering.
- 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.
- PhD in computer science, machine learning, applied statistics, mathematics, physics, engineering, or a related field, with particular expertise in any of the following:
- operator learning (neural operators), or other probabilistic methods for PDEs;
- geometric deep learning or other 3D computer vision methods for point-cloud or mesh-structured data;
- generative models for geometry and spatiotemporal data (VAEs, Diffusion Models, Bayesian non-parametric, scaling to large datasets, etc.).
- Ideally, >4 years of experience in a data-driven role in a professional industry setting, where you have been instrumental in:
- building machine learning models and pipelines in Python, using common libraries and frameworks (PyTorch / CUDA, ideally with exposure to JAX, NumPy / SciPy), especially including deep learning applications;
- developing models for bespoke problem settings that involve high-dimensional data (spatiotemporal, geometric, physical); &
