About us
Re-architecting Engineering for the Age of Intelligence
PhysicsX is the physics AI company for industrials. The company’s mission is to accelerate hardware innovation by overhauling what industrial engineering and manufacturing look like today. PhysicsX is building a new simulation software stack to deliver deep physics AI enablement across the entire engineering lifecycle. The company partners with leading organisations in aerospace & defence, automotive, semiconductors, materials, and energy & renewables, supporting them on some of their most critical and complex challenges. PhysicsX is headquartered in the United Kingdom, with offices in London, New York, and Singapore and an expanding presence in the Bay Area.
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.
Geometry is at the heart of how we think about engineering.
You will work at the frontier of 3D geometry representation and generation, with a focus on making both of these ready for engineering. You will also work on closing the coupling between geometry and physics, towards generating shapes that are driven by physical objectives.
What you will do
- Own a research work-stream: set its technical direction, align priorities with internal and external stakeholders, and apply judgement and taste to drive progress.
- Design and train generative models over 3D geometry — representations, latent spaces, and the objectives that decide whether generated geometry is physically usable rather than merely plausible.
- Work against production numerical solvers, so model quality is measured in validated physics rather than proxy metrics.
- Work with our ML engineers, simulation engineers and customers to turn engineering challenges into mathematical formulations.
- Champion research directions valuable to the company, nurture more junior colleagues, and publish for both academic and non-academic audiences.
What you bring to the table
- PhD in CS, ML, mathematics, physics, engineering or a related field, with demonstrated expertise in generative modelling or learned representations of 3D geometry, covering one or more of:
- generative models for geometry — VAEs, diffusion and flow matching, autoregressive latent models, scaled to large datasets;
- geometric deep learning and 3D vision over point-cloud, mesh, voxel or implicit-field data, including sparse convolution and sparse attention;
- neural fields and shape autoencoders.
- Relevant experience in industry or a research group of comparable intensity, instrumental in:
- building models and pipelines in PyTorch/CUDA;
- bespoke problem settings involving geometric or 3D data;
- iterating on architecture and inductive bias;
- combining theoretical reasoning with empirical intuition;
- running experiment pipelines that produce comparable results.
- Ability to scope and deliver projects, with strong problem-solving skills.
- Enthusiasm for deep learning and probabilistic methods applied to science and engineering.
- Publications at premier conferences: SIGGRAPH, SIGGRAPH Asia, CVPR, ICCV, ECCV, NeurIPS, ICML or ICLR, and relevant journals: TOG, TPAMI, JMLR.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Desirable:
- operator learning or probabilistic methods for PDEs;
- self-supervised pretraining for 3D vision and/or physics surrogacy;
- generative inverse design linking geometry to physics objectives.
What we offer
-
Build what actually matters Help shape an AI-native engineering company at a formative stage, tackling problems that genuinely matter for industry and society. This is work with real-world impact - and something you can be proud to stand behind.
-
Learn alongside exceptional people Work with a high-caliber, collaborative team of engineers, scientists, and operators who care deeply about doing great work, and about helping each other get better. We come from diverse backgrounds, but we share a commitment to operating at the highest level and addressing some of the most complex challenges out there. If you’re ambitious, thoughtful, and driven by impact, you’ll feel at home.
-
Influence over hierarchy We operate with a flat structure: good ideas win - wherever they come from. Questioning assumptions and challenging the status quo isn’t just welcomed, it’s expected.
-
Sustainable pace, long-term ambition Building meaningful technology is a marathon, not a sprint. We believe in balancing focused, ambitious work with a life beyond it. Our hybrid model blends time together in our Shoreditch office with work-from-home days, giving you the flexibility to work sustainably while staying connected in person.
