Forward Deployed Applications

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.

The Role

PhysicsX is building a new category of engineering software — one where physics AI models don't just augment existing workflows, but fundamentally redefine what's possible in design and operations. Our Product team is expanding a portfolio of Engineering Applications that bring this capability directly to the engineers, scientists, and operators who need it most. If you're excited by the challenge of turning cutting-edge AI and simulation research into tools that change how the world's most complex engineering problems get solved, this is the team to do it with.

You'll join the Forward Deployed Applications team, a group that sits at the intersection of product development and customer delivery. Your primary mission is to work closely with customers on real engineering problems — and to turn what you learn into generalised, reusable product capabilities that raise the ceiling for every PhysicsX user. This isn't a traditional customer-facing role or a pure product role: it's the feedback loop that keeps our product grounded in genuine engineering value. You'll work alongside simulation engineers, data scientists, ML engineers, and backend developers, with significant autonomy in how you approach problems, and a direct line of influence over the direction of our growing application suite.

What you will do

You'll spend meaningful time in conversations — with users unpacking real engineering workflows, with Delivery teams translating those needs into concrete requirements, and with the Product team debating which patterns are worth generalising. Expect to be a connector as much as a builder, and to develop a strong instinct for which customer insights have product-wide implications. You'll be expected to bring both rigour and initiative: writing clean, well-considered code, contributing to architecture decisions, and pushing back constructively when a bespoke solution risks diverging from the product vision. This team operates with a high degree of autonomy, and the expectation is that you use it thoughtfully. On any given day you might be designing a 3D visualisation that makes a fluid dynamics simulation instantly legible to a non-specialist, building a React interface that surfaces AI model outputs in a live operational context, or refactoring a one-off delivery prototype into something the whole platform can build on. The problems are genuinely novel, and the solutions you build here will define what engineering software looks like next.

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.
