Lead Forward Deployed Software Engineer

Physics

X 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, Physics

X 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.

Your role , first and foremost, is to help our customers solve their most impactful problems. As Lead Forward Deployed Software Engineer, you’ll define how Physics

X’s Forward deployed engineers deliver software that enables our customers to build better, faster, and cheaper across large‑scale customer projects. You’ll set the standard for how software engineering is done across delivery and codify solutions developed with customers into our core product offering.

We’re looking for someone who’s built a team from the ground up and has a proven track record of cultivating engineering excellence to deliver outcomes
. Success will require deep technical project management expertise, extreme ownership of outcomes, and an ability to immerse in customer workflows and partner with customer teams to solve complex engineering problems at pace.

• Own the technical delivery plan for multiple projects or work‑streams. Translate business objectives into a roadmap with milestones, dependencies, and acceptance criteria.
• Embed with customers to land production deployments and drive adoption. Map workflows, shape tools/integrations, and translate requirements into a delivery plan. Lead onboarding, adoption, and change management.
• Cultivate engineering talent, building out the Forward Deployed Software engineering team in London.
• Travel to customer sites in North America, Europe, Asia, Oceania, for an average of 3‑4 weeks per quarter, where you'll collaborate closely with customers to build solutions on‑site.
• Own the scoping of new projects and work‑streams with existing customers and taking part in bringing new customers to Physics

We work across a wide range of engineering disciplines, all of which are high complexity. Someone with a track record of solving hard problems is a must, a background in Mechanical Engineering or similar is a plus. This role deals with breadth across the full stack, having a solid foundation in software engineering, API design, and deploying applications to production is desired.

Success will be measured by impact – delivering measurable value against customer goals, driving adoption, and becoming indispensable to their workflows. You own the responsibility to get things done and will pick up the skills and experience needed to solve novel problems quickly.

We build tools that customers need, not just the ones they want. So you must be someone who is customer‑obsessed and can work alongside our customers to understand their problems and build applications that change the way they do engineering.

• Be part of something larger. Make an impact and meaningfully shape an early‑stage company. Work on some of the most exciting and important topics that exist out there. Do something you can be proud of.
• Work with a fun group of colleagues who support you, challenge you, and help you grow. We come from many different backgrounds, but what we have in common is the desire to operate at the very top of our fields and solve truly challenging problems in science and engineering. If you are similarly capable, caring, and driven, you'll find yourself at home here.
• Experience a truly flat hierarchy. Voicing your ideas is not only welcome but encouraged, especially when they challenge the status quo.
• Work sustainably, striking the right balance between work and personal life.
