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
Join our dynamic product team in our fast-growing startup, building an AI platform for Data Scientists and Simulation Engineers to deploy Deep Physics Models. You will be one of a growing number of Frontend Software Engineers, collaborating in a cross-functional team with autonomy to drive implementation decisions. Bring your expertise in building frontend systems, plus familiarity with micro-frontend architectures and Kubernetes. A passion for software engineering, collaboration, and end-to-end ownership is key.
What you will do
- Build & Evolve the Platform: Develop and maintain a frontend that supports complex ML workflows—from 3D visualizations to seamless API integrations
- Optimise User Experience: Ensure our interface is visually appealing and high-performing using advanced caching strategies, performance monitoring, and accessibility best practices
- Drive Innovation: Work with a modern, production-grade stack including NX monorepo, module federation for micro-frontend scalability, TanStack Query, Zustand, and GitHub Actions CI/CD, and help shape how it evolves as the platform grows
- Collaborate & Own: Work closely with product, design, and backend engineers in a small cross-functional team, contributing to architecture decisions and taking full ownership of features from implementation through production
- Learn & Share: Engage in conferences and meet-ups, share knowledge with colleagues, and continuously learn from one another
What you will bring to the table
- Frameworks & Libraries: React, TypeScript, and state management (Zustand, Redux, or similar)
- Performance Optimisation: Code splitting, lazy loading, and React performance tools
- APIs & Data Handling: REST, Long Polling, WebSocket, GraphQL, caching strategies, and data-heavy API interactions
- UX & UI: Responsive design, design systems, and prototyping (Figma, Excalidraw)
- Testing & Quality: Unit and integration (Jest), E2E testing (Cypress)
- Security & Accessibility: OAuth/JWT, XSS/CSRF prevention, WCAG, and ARIA
- CI/CD & Developer Tooling: NX, GitHub Actions, monorepos, pipelines, and micro-frontend architectures
- Specific Technologies: Familiarity with data visualisation and 3D rendering libraries such as Plotly, ECharts, VTK, Three.js, WebGL, WebGPU, or WebAssembly (desirable)
