Senior Fullstack Engineer

Applied Intuition, Inc. is powering the future of physical AI. Founded in 2017 and now valued at $15 billion, the Silicon Valley company is creating the digital infrastructure needed to bring intelligence to every moving machine on the planet. Applied Intuition services the automotive, defense, trucking, construction, mining and agriculture industries in three core areas: tools and infrastructure, operating systems, and autonomy. Eighteen of the top 20 global automakers, as well as the United States military and its allies, trust the company’s solutions to deliver physical intelligence.

We are an in-office company, and our expectation is that full-time employees primarily work from their Applied Intuition office 5 days a week. However, we also recognize the importance of flexibility and trust our employees to manage their schedules responsibly. This may include occasional remote work, starting the day with morning meetings from home before heading to the office, or leaving earlier when needed to accommodate family commitments.

About the role:

You would be the first fullstack engineer we hire onto the UK team, joining software and autonomy engineers whose tools are already relied on across live programmes. As that portfolio grows, we are bringing in dedicated fullstack expertise to shape how the user-facing products we ship are designed and built. Every day is different: designing an interface around how a customer actually operates, building the services and APIs behind it, working with our design team so what we ship in London is coherent with everything else Applied Intuition builds, or taking what we learn on a programme and landing it in the products of the teams we work alongside. You will move between languages and layers as the problem demands, and you will have a strong voice in how these products get built.

At Applied Intuition, you will:

• Take new products from concept through to production at the pace our programmes demand, owning the technical and product decisions along the way.
• Build features end to end, from the interface through the API to the services and data behind it.
• Set the front-end foundations for our UK products: shared components, sensible patterns, and a design language consistent with the rest of the company.
• Decide, with the team, when a new capability should stand alone and when it belongs in our core product offering.
• Get the improvements we identify on programmes into the products our other teams build, so what we learn in the field shapes the wider roadmap.
• Engineer security in from the first commit, and build software that holds up to the environments and the scrutiny our customers operate under.
• Help raise the bar for how user-facing software is built here, and build products people depend on and that you are proud of.

We’re looking for someone who has:

• Bachelor's degree in computer science/related engineering field.
• 5+ years of hands‑on fullstack experience shipping and supporting production web applications.
• Deep expertise in React and TypeScript, or another modern front‑end framework, and strong, well‑founded opinions about building interfaces for data‑heavy workflows.
• Adaptability across languages and comfort owning the whole stack; our products span TypeScript, Go and Python, and we care more about your judgement than your syntax.
• Experience working closely with designers and product managers, and a track record of getting your requirements into products you don't own.
• Command of application security, and experience developing in Docker and containerised environments on Linux.

Travel Requirements:

General willingness to travel for company business between our offices, as well as to customer sites.

Security Requirements:

Must have ability to hold UK Security Clearance (current or previous preferred).

Nice to have:

• 7+ years of experience building fullstack applications, including time as the senior voice on front-end architecture.
• Hands‑on experience with 3D or geospatial visualisation in the browser, such as CesiumJS, Three.js or WebGL.
• Experience building or extending a design system used across more than one team.
• Experience deploying and operating what you build, on Kubernetes or similar.
• Experience with autonomy, robotics, simulation or other systems that generate data at a scale browsers were never designed for.
• Experience working on projects related to national security for one or more government agencies.
• References who will describe them as low‑ego, historically motivated, thoughtfully opinionated, strong communicators and curious listeners.
