Senior Platform Engineer

PhysicsX is a deep-tech company of scientists and engineers, developing machine learning applications to massively accelerate physics simulations and enable a new frontier of optimisation opportunities in design, engineering, and systems control. We help our customers fundamentally improve their concepts and designs, transform their engineering processes and drive operational product performance. We do this in some of the most advanced and important industries of our time – including Renewables & Sustainability, Space, Aerospace, Medical Devices, Additive Manufacturing and Energy. Our work creates positive impact for society, be it by improving the design of artificial hearts, reducing CO2 emissions from aircraft and road vehicles, or increasing the performance of wind turbines. 
The RoleWe’re looking for enthusiastic and passionate Senior Platform Engineers to join our Cloud Engineering team at PhysicsX. The Cloud Engineering team is fundamental to, and underpins, how our software is deployed for use both internally and by customers. We collaborate across the organization to support our product teams as they build our enterprise software-as-a-service platform, our delivery teams tackling complex engineering challenges with our customers, and our research teams working on cutting-edge AI research and technology. The Cloud Engineering team is critical in enabling all of our teams to push the boundaries of what’s possible in the world of artificial intelligence and machine learning.
As a Platform Engineer, you will be paramount to the development and implementation of our internal developer platform, significantly enhancing the experience of our software engineers at scale. This role presents an exciting opportunity to shape the future of our cloud estate and self-service internal developer platform in a dynamic environment where innovation and impact are prioritized.
Our Cloud Engineering team is diverse in skillset, working collaboratively on infrastructure and corresponding tools that constitute our internal developer platform offering. Recent projects have included supporting our public release of Ai.rplane; optimizing cloud-based GPU workloads for model training, and re-architecting our cloud estate to modernise, standardise, and reduce cost. You can find out more about PhysicsX and our work from our AWS re:Invent 2024 talks, including how we’re using high-performance computing to drive innovation, or how large geometry models are transforming advanced engineering.
If this sounds exciting to you, we would love to talk — even if you don’t tick all of the boxes.
Note: We do not provide visa sponsorship in the US. Please only apply if you have the right to work in the US.
