AI Engineer Assistant

This role sits at the intersection of product, infrastructure, and user experience. You will turn the Build Assistant, Dougie, into a world-class product: turning the world’s best geospatial data and tooling layer into something usable, powerful, and trusted by institutions. Strong product sensibility is not optional; the ability to execute on it is a force multiplier.

You’ll work closely with James SE and Ben McClusky.

You can expect to:

• Design, build, and deploy the Build Assistant: an AI-native product that sits on top of complex geospatial data, models, and workflows, and makes them usable through a single coherent interface.
• Build a non-deterministic, multi-agent orchestration layer that coordinates tools, data sources, and human input to deliver reliable outcomes in ambiguous, real-world scenarios.
• Translate institutional real estate and infrastructure workflows into a clean ontology that agents and humans can operate against.
• Own and ship full-stack features end-to-end, from agent behavior and orchestration to UI, performance, and production reliability.
• Build beautiful, opinionated user interfaces on top of Build’s design systems, where clarity, speed, and trust matter more than novelty.
• Work directly with domain experts and customers to pressure-test assumptions and ensure the assistant delivers real leverage, not demos.
• Solve unsolved problems at the intersection of AI systems and the physical world, where correctness, explainability, and failure modes matter.
• Build software that scales in both usage and complexity, with a bias toward robustness, observability, and long-term maintainability.

• Radical autonomy, real ownership: High standards. Minimal bureaucracy. You own problems end-to-end, choose how the work gets done, and are accountable for exceptional outcomes. Ownership is matched with meaningful, generous equity.
• An accelerated founder’s track: Build is for builders. If you want to learn what it actually takes to create a generational company – Product judgment, execution speed, and accountability – there is no faster path than building from zero when everything is for grabs.
• Elite teammates, uncompromising bar: You work with people who think clearly, execute relentlessly, and take full ownership. The team you build becomes the company you build. Growth here is not just professional; it reshapes how you operate and in return how Build operates.
• Perpetual adventure: We attract the strongest of the strange. Extraordinary experiences are part of the culture - from the food we eat together to the space we occupy. Intensity is intentional.
• Shape the built world: We are rebuilding how the physical world gets made. Our software doesn’t live in the abstract - it turns into real projects breaking ground because we exist. We work with the largest institutions, push the frontier of AI, and watch our decisions translate directly into the world around us.
