Software Engineer - Simulation / Unreal focus

All3 is transforming how buildings are conceived, developed, and delivered. We combine AI-powered design with robotic prefabrication and on-site assembly to build custom architecture at the cost and speed of mass production - unlocking even the most complex sites.

We’re currently seeking a Software Engineer – Simulation / Unreal Focus to join our team, focused on building a deterministic, physics-accurate simulation platform for multi-robot construction assembly. You will develop high-performance Unreal-based systems that replicate real-world robotic behaviour and enable large-scale autonomy testing.

Responsibilities:

• Building a scalable, headless, deterministic simulation platform for multi-robot on-site construction assembly;
• Simulating coordinated robotic systems operating in shared physical space. Including manipulation, contact, constraints, tolerances, and assembly sequencing;
• Implementing physically grounded senso...
