Forward Deployed Software Engineer at PhysicsX – Shoreditch, London

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.

Your role, first and foremost, is to help our customers solve their most important problems. As a Software Engineer, this takes the form of building and deploying applications that utilize the power of our physics AI models to enable our customers to build better, faster, and cheaper. As a member of the delivery team, you'll work directly with customers, data scientists, and machine learning engineers to develop applications that change the way advanced engineering is done. We're looking for someone who can grasp advanced engineering concepts across multiple industries, fundamentally understand the problems that engineers face, and build tools to solve these problems.

Who We’re Looking For

• Technical ability: Solve hard problems across a wide range of engineering disciplines. A background in Mechanical Engineering or similar is a plus. Solid foundation in software engineering, API design, and deploying applications to production is desired.
• Proactivity & high ownership: Drive impact for our customers. Be a go-getter, naturally inclined to find problems and solve them end-to-end. Own responsibility to get things done and pick up the skills needed to solve novel problems quickly.
• Solution-focused: Build tools that customers need, not just the ones they want. Be customer-obsessed and work alongside customers to understand their problems and build applications that change how they do engineering.

What a day might look like

• Collaborate with data scientists and machine learning engineers to ship physics models to our customers in a way that delivers maximum value.
• Work with designers and front-end engineers to shape the UX in line with customer needs.
• Design end-to-end applications: shape tools that are impactful for customer teams, construct low-lift prototypes, ship them directly to customers, and rapidly iterate on user feedback.
• Backend development: build and maintain RESTful APIs (FastAPI) and microservices in Python to serve large physics models. Deploy applications to the cloud (Helm, Kubernetes, Terraform, AWS/Azure).
• PhysicsX development: distill complex solutions into fundamental components, pitch and execute new features on top of our core platform, and drive the direction of PhysicsX to solve ever harder problems.

What we offer

• Equity options – share in our success and growth.
• 10% employer pension contribution – invest in your future.
• Free office lunches – great food to fuel your workdays.
• Flexible working – balance your work and life in a way that works for you.

• Enhanced parental leave – support for life's biggest milestones.
• Private healthcare – comprehensive coverage.
• Personal development – access learning and training to help you grow.
• Work from anywhere – extend your remote setup to enjoy the sun or reconnect with loved ones.

We believe diversity fuels innovation, and we're building a culture where everyone belongs. We're proud to be an equal-opportunity employer, welcoming talent of all backgrounds, identities, and experiences. Changing the face of tech takes action, which is why we actively encourage individuals from historically under-represented groups to apply.
