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.

Who We're Looking For

As a Senior CFD engineer in Delivery, you are a problem solver and a builder who is passionate about creating practical solutions that enable customers to make better engineering decisions. You are someone who can grasp and apply advanced engineering concepts across multiple industries, and you excel at working directly with customers (and often side-by-side with them on-site) to build CFD models that are integrated into AI-tools that are both useful and used.

You bring strong expertise in fluid mechanics, heat transfer, and multiphase modelling, with a solid ability to apply fundamental knowledge to real-world phenomena. Highly proficient in at least one of Star-CCM+, OpenFOAM, or Fluent, you're adept at using these tools to create efficient, scalable workflows that drive impactful results. Coding skills in Python and/or Java, or the ability to quickly learn programming languages, is an advantage.

With at least 3-5 years of industry experience (post Bachelors, Masters or PhD) in a commercial, non-research environment, you're ready to hit the ground running. You're comfortable setting up CFD simulations independently, interpreting results with depth, and making informed decisions based on solid engineering judgement.

As a Senior CFD engineer, you won't just create models, you'll build what truly matters.

This Role

In this role, you'll work closely with our Data Scientists, Machine Learning Engineers, and customers to understand and define the engineering and physics challenges we are solving. You'll play a crucial role in delivering high-fidelity simulations by:

- Independently building complex multi-physics models from the ground up to simulate and understand complex real-world phenomena, including using experimental data to validate simulations and ensure accuracy.

- Automating simulation pipelines, enabling fast optimization and parametric CAD coupling for efficient results.

- Leveraging our cloud platform and on-premise HPC to accelerate high-fidelity models beyond smart model setup and meshing choices.

- Collaborating closely with customers to understand their engineering challenges and solve them using simulation (& AI). You will present results clearly and suggest next steps while balancing accuracy and efficiency, often working under pressure to meet tight deadlines.

- Working at the intersection of CAE and data science, generating accurate simulation results and predictions to train advanced Machine Learning and Deep Learning models.

- Continuously improving engineering practices, adapting CAE model setups and outputs to support the development of Deep Learning surrogates.

- Mentoring junior engineers as part of a collaborative team.

- Travelling to customer sites in North America, Europe, Asia, Oceania, an average of 2-3 weeks per quarter, where you'll collaborate closely with customers to build solutions on site.

As the role evolves, there are exciting opportunities for growth as an individual contributor or a technical lead, especially if you're driven to take ownership of more complex projects and lead the direction of future solutions.

Please note, this role is based in London, working 2-3 days per week in our central office.
