About the Company

Our client is a high-growth, mission-driven startup re-industrialising the West. They build and operate software-defined factories that produce critical components for the aerospace, defense, and energy sectors.

Launched in 2024 by a founding team of ex-Palantir engineers and defense experts, they are scaling from 4 to 25 factories globally by the end of next year. They are building a proprietary operating system that orchestrates a massive network of production facilities and real-time factory automation—effectively bringing the "cloud" to the factory floor.

The Role

We are looking for a high-agency Full Stack Software Engineer (2–5 years exp) to join a founding-level team. This is a generalist role for an engineer who wants to see their code solve real-world physical problems. You won't just be building dashboards; you’ll be building the infrastructure that controls high-precision machine tools in real-time.

This is a flat hierarchy environment with no middle management. You will work directly with leadership and the production team to turn operational pain into impactful software products.

Responsibilities

• Architect and Develop: Build critical systems for factory automation, real-time data processing, and UX.
• Full-Stack Ownership: Take end-to-end responsibility for the software stack, from infrastructure and backend services to machine learning and frontend monitoring.
• Rapid Iteration: Work on the ground in the factories, deploying and iterating software that directly controls production.
• Mission-Critical Engineering: Lead projects from conception to deployment, ensuring fault-tolerant systems operate in high-stakes environments.
• Scale the Network: Optimize machine tool utilization and help orchestrate a rapidly growing network of distributed factories.

What We’re Looking For

• 2–5 Years Experience: Exceptional track record at a Tier-1 VC-backed startup or top-tier engineering firm (e.g., Palantir, Tesla, SpaceX, or similar).
• Technical Stack: Strong hands-on skills in TypeScript, React, Postgres, and AWS.
• UX Preference: A slight preference for candidates with strong UX/Frontend experience who can simplify complex industrial workflows.
• High Agency: A pragmatic, "founder-mindset" engineer who works independently and moves with extreme speed.
• Mission Alignment: Deeply motivated by the mission to reinvigorate Western manufacturing and sovereign capability.
• On-site Commitment: Willingness to work 5 days a week on-site in London to collaborate directly with the hardware and production teams.

What’s on Offer

• Salary: £100k – £200k (Top-of-market for Tier-1 talent).
• Equity: Meaningful, above-average equity (founding-level grants).
• Real-World Impact: See your software running on the factory floor every day, building parts for the next generation of rockets and planes.
• Elite Talent Density: Work alongside a high-performance team of ex-Palantir, ex-Special Forces, and Tier-1 startup veterans.
• Growth: A chance to be one of the first 20 hires in a company scaling to 60+ people in the next 12 months.

Hiring Process

1. Intro Interview (30 mins): Culture, mission alignment, and background.
2. Technical Interview: Deep dive into full-stack capabilities and system design.
3. Site Visit & Technical Challenge: Visit the London facility, meet the team, and solve a real-world technical problem on-site.
4. Final Interview: Meeting with the CEO and core leadership team.
