AI-driven distributed metal-component manufacturing
Isembard is rebuilding industrial capacity through a connected network of factories. We bring skilled people, advanced machine tools and our own software, MasonOS, together to make precision components for aerospace, defence, energy and robotics.
MasonOS coordinates our factory network across four countries. This role builds the part of it that makes decisions: which site takes an order, which supplier fills a gap, how the schedule changes when a machine goes down.
It is backend engineering with physical consequences. When the routing is wrong, metal sits still. You will have high ownership and real influence over the architecture, with travel to new sites when deploying MasonOS. The package includes equity.
Build order routing across the sites in our network.
Build supplier orchestration and the data behind it.
Design backend architecture for more sites than we run today, not just the ones we have.
Deploy MasonOS into new sites as the network grows, and adapt your abstractions when they meet a real shop floor.
Set and defend the reliability standards for a system that production depends on.
Strong backend engineering fundamentals.
Real experience with distributed systems.
Good judgement about failure: what is allowed to degrade, and what must never break.
Comfort working in high-security environments.
Typically three or more years of professional experience, though we will consider exceptional early-career engineers who can add value quickly.
Isembard is a London-based software-first manufacturing network that runs AI-powered factories to produce high-precision metal parts for aerospace, defence, energy, and robotics. It uses modular factory builds and a franchise model with MasonOS—the AI-native operating layer that handles quoting, CAD/CAM, procurement, scheduling, quality assurance and logistics across 5-axis CNC and robotic cells. Factories hold ISO 9001, Cyber Essentials and JOSCAR certifications. The company has raised a $9M seed and a $50M Series A to grow to about 25 facilities by late 2026 in the UK, US, Germany, France and Ukraine, serving both defence/autonomy startups and established OEMs, and sometimes managing complete supply chains for customers.
