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.

WHO WE’RE LOOKING FOR

As a Senior CFD Engineer (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 (often directly on-site) to build CAE models that are

integrated into AI-tools that are both useful and used.

We're building our Singapore presence from the ground up. This is a rare opportunity to join at the founding stage of a regional

team, with the autonomy to help define what this team becomes.

You bring deep expertise in fluid mechanics, heat transfer, and multiphase modelling, with a solid ability to apply fundamental

knowledge to real-world phenomena across a wide range of engineering applications. Highly proficient in at least one of Star-CCM+,

OpenFOAM, or Fluent and adept at automating these tools to create scalable optimisation workflows that drive impactful results.

Experience in parametric CAD modelling (NX or CATIA) and coding in Python/Java, (or the ability to quickly learn programming

languages), is an advantage.

With 3-5 years of industry experience (post Masters or PhD) in a commercial, non-research environment, you’re ready to hit the

ground running. You’re confident setting up CFD simulations independently, interpreting complex results with depth, and making

informed decisions based on solid engineering judgement.

THIS ROLE

In this role, you’ll work closely with our Data Scientists, Machine Learning Engineers, and customers to understand and define the

engineering challenges we are solving.

You’ll play a crucial role in delivering high-fidelity simulations by:

Independently building complex multi-physics models from geometry clean-up and meshing, to simulating and post-processing

complex real-world phenomena, integrating experimental data for model validation.

Building robust parametric CAD models (NX or CATIA) coupled with simulation pipeline automation, for executing advanced design

optimization and DoE studies.

Partner with customers to address their most complex engineering challenges through advanced CAE & AI solutions; present

results clearly, recommend actionable next steps, and balance accuracy with efficiency under tight deadlines.

Working at the intersection of CAE and Data Science to generate high-quality simulation datasets for training Machine/Deep

Learning models. Leveraging data sampling techniques to efficiently capture the design space, reduce computational cost, and

enhance model accuracy.

Accelerate high-fidelity modelling by using Flux (our cloud platform) and on-premise HPC resources, going beyond smart meshing

and model setup to achieve real performance gains.

Continuously improving engineering best practices, adapting CFD model setups and outputs to support the development of Deep

Learning surrogates.

Combining project leadership with a strong commitment to mentoring junior colleagues, contributing to a culture of

collaboration, growth, and shared success.

Traveling globally (North America, Europe, Asia, Oceania) up to 2–3 weeks per quarter to work side-by-side with customers in

building solutions on-site.

As the role evolves, there are exciting opportunities for growth as an Individual Contributor (IC) or a Team Lead (TL), especially

if you’re driven to take ownership of more complex projects and lead the direction of future solutions.

We value diversity and are committed to equal employment opportunity regardless of sex, race, religion, ethnicity, nationality,

disability, age, sexual orientation or gender identity. We strongly encourage individuals from groups traditionally

underrepresented in tech to apply. To help make a change, we sponsor bright women from disadvantaged backgrounds through their

university degrees in science and mathematics.

We collect diversity and inclusion data solely for the purpose of monitoring the effectiveness of our equal opportunities policies

and ensuring compliance with UK employment and equality legislation. This information is confidential, used only in aggregate

form, and will not influence the outcome of your application.
