General Manager
Isembard
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, defense, energy and robotics.
We're opening Isembard's first factory in California, and the General Manager launches it. You'll choose the site, hire the team, win the first customers and run the factory day to day, with the backing of our factories in Dallas, London, Hamburg and Paris. The exact site is still to be chosen, and choosing it is part of the role.
You'll own the site's revenue, delivery, quality and security, and bring it onto MasonOS, the software that runs every Isembard factory. It is a high-trust mandate with direct impact on aerospace, defense and industrial supply chains. The package includes equity, medical, dental and vision insurance, a 401(k) with company match, paid time off and parental leave.
Find, qualify and secure the site: power, space, layout and the machines that go in it.
Hire and lead the first team of machinists, CAM programmers, quality and operations people.
Build relationships with aerospace, defense and industrial customers, and turn them into long-term demand for machined parts.
Find and bring on franchise partners across the region.
Run the factory to strict quality and security standards, and deploy MasonOS on the shop floor.
Experience leading an operationally intensive business, site or function.
Strong operational and logistical judgment, and comfort building from nothing.
Credibility with engineers and customers, and a real understanding of how things get made.
High integrity and a mission-driven mindset.
Useful, not essential: manufacturing, aerospace or defense experience, a network across California's industrial and defense base, experience opening a new site, or an engineering degree.
Isembard is an equal opportunity employer.
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.
