Product Engineer

E17, London | 3+ days on-site

About Us

We're automating homebuilding. Construction is one of the least-automated industries in the world. This is how that changes. AUAR deploys robotic MicroFactories powered by our software and physical AI robotics stack for automated timber housing production.

Our platform, MasterBuilder, takes a building design and generates executable robot code for every panel. Our deployable MicroFactories produce full-scale framing panels right on the construction site — wall, floor, roof — on demand, in sync with the build. No trucking. No delays.

AUAR's software has physical consequences on real construction sites, deployed today. Code you write becomes part of how the MicroFactory runs. A bug can break a production run. A workflow you design shapes how a whole category of production works. That changes how you think about shipping and testing. The stack spans robotics integration, CAD ingestion, real-time production monitoring, and AI-assisted design parsing. We've built it and proven it on live construction sites. Now we're growing the team and looking for an engineer to help build it into a platform operators depend on every day.

The Product Engineer Role

We're looking for someone who writes code that doesn't just run in a browser: it moves a robot arm, cuts timber to micrometre precision, and assembles load-bearing panels to structural engineering specs.

As a Product Engineer, you will own the full stack of what operators and engineers see — the frontend, the workflow, and the problem they solve. You will be in the room with the Software Engineers, UX designers, robotics developers, and construction experts, asking: What problem does this operator actually have? How do we solve it? And then you will build it. You will be reaching into backend services, APIs, and data pipelines as needed to deliver your full vision. You will be testing on the factory floor. You'll pair directly with hardware engineers, operators, and designers — especially when debugging next to the robot.

AI is the third axis of this role. We're looking for someone genuinely AI-native: you use it as a default in your own work, implement agents that improve the development stack, and raise the collective AI capability of the team. In the product, you build machine intelligence where it changes what operators can actually do, and push back where it doesn't. You can tell the difference between a capability that genuinely shifts how someone works and one that sounds impressive in a demo. And you're thinking ahead: as AUAR integrates vision-language models for robotics, the interface may shift — command bar instead of dropdown, voice-first instead of click-driven. You build systems that can evolve with the underlying AI.

Problems You'll Work On

• Operator UIs for production control. Interfaces for monitoring production runs and recovering from failures mid-run — with no QA buffer between your code and the factory floor.
• Design validation. An AI layer that flags manufacturing issues before they reach the floor: panel geometry that wastes 40% of a sheet, assembly sequences that create physical bottlenecks, configurations that pass structural checks but fail at production.
• Failure recovery. When the MicroFactory hits a fault mid-run, the operator decides what to do. An AI that reads camera and sensor feeds and proposes a recovery path — or for simple faults, executes it automatically — changes how operators work under pressure.
• Production insight on demand. A natural language interface over live production data so operators can get answers fast when things are moving fast.
• Real-time 3D visualisation. Translating building designs into precise robot instructions and rendering both the model and live manufacturing state in-browser, so engineers can verify what the robot is about to do — and understand what went wrong when it doesn't.

What good looks like

• You ship working code every day, not perfect code eventually.
• You step back from a feature and say "this isn't solving the problem" and redesign it.
• You write UI that operators actually want to use, because you've watched them try to use it.
• You move between "why is this button in the wrong place" and "how do we structure this data pipeline" without losing your thread.
• You feel the stakes. A bug you miss could break a production run 200 miles away. That clarity sharpens how you code.
• AI is a natural part of how you work - in your own workflow and in what you build. You don't need to be told to reach for it.

Who this is for

You've built software that has to work, not just look good. Your background might be shipping production software at scale, building tools where the feedback loop between code and outcome is immediate, or a domain like architecture or engineering where you learned to code because you wanted to automate something.

What matters more than your background: you think in problems, not tasks. You make decisions without perfect information. You're independent enough to pick up a problem and run with it, but collaborative enough to know when to ask.

You are either already comfortable with our stack -TypeScript/Node backend, React + Three.js frontend, Python/C++/RAPID on the robotics side - or motivated and able to learn fast. You need genuine curiosity about how physical systems work.

This role suits people who thrive with ambiguity and quick iteration. If you need a detailed spec before starting, or if you're primarily motivated by optimising scale and metrics, this probably isn't the right environment.

You must have:

• 3+ years of professional software engineering with genuine full-stack capability — comfortable shipping excellent user‑facing software and equally comfortable in backend services, APIs, and data models.
• Fluency in TypeScript, React, and Node.js.
• A native relationship with AI tooling: using it where it helps, knowing when it doesn't.
• Early‑stage start‑up experience, or a clear‑eyed understanding of what you're signing up for: fast‑moving, shifting priorities, work that doesn't fit a job description. For the right person, that's the point.
• A willingness to be on site 3+ days a week on our factory floor, in Blackhorse Road, London
