Principal Systems Engineer - FULL RELOCATION PACKAGE - to $300k - ID48026 in London

What if the next computing revolution was still being figured out in labs, late at night, by a handful of people? Would you stay where things are predictable or step into something that could redefine everything?

This is not a conventional systems engineering role. Our client is building machines that do not yet fully exist — at least, not in the way they will. Quantum computing isn’t just an evolution of classical systems; it’s an entirely new paradigm. And that means the rules of engineering are still being written.

They are looking for exceptional systems thinkers across Europe — individuals ready to relocate to the US (with full visa and relocation support) and help turn breakthrough science into scalable, working quantum machines. This is one of those rare moments in technology where the future is still fluid.

There is no finished blueprint here. Requirements aren’t handed down — they’re discovered. Systems aren’t static — they evolve with every experiment. Progress isn’t linear — it’s iterative, exploratory, and sometimes unpredictable.

• To bring clarity where there is ambiguity.
• Structure where there is complexity.
• And momentum where there is friction.

• Shape systems that have never existed before.
• Help define and evolve the architecture of large-scale quantum machines across hardware, control systems, and software layers.
• Work at the frontier of science and engineering.
• Collaborate daily with quantum scientists, translating experimental insight into real, buildable systems.
• Turn ambiguity into progress.
• Guide the co-evolution of requirements — capturing intent, refining understanding, and enabling teams to move faster with confidence.
• Make complexity visible and actionable.
• Build system-level clarity around architecture, integration status, and technical risk — helping teams align and execute effectively.
• Drive integration at a fundamental level.
• Ensure hardware, firmware, and software come together cohesively — not just in theory, but in real-world machine behaviour.
• Redefine how systems engineering works.
• Introduce just enough structure to accelerate progress — without slowing discovery or innovation.
• Create early impact.
• Deliver tangible improvements that immediately reduce friction — whether that’s solving an interface issue, clarifying a failure mode, or improving integration readiness.

You’re not just experienced — you’re adaptable. You’ve built and integrated complex hardware-software systems before, perhaps in aerospace, robotics, automotive, or advanced instrumentation. But more importantly, you’re comfortable when things aren’t fully defined.

In this role, you’ll:

• Work closely with scientists in lab environments, learning how systems behave in practice.
• Translate emerging scientific goals into evolving engineering requirements.
• Develop living system architectures that reflect reality — not just theory.
• Drive integration, validation, and system-level testing strategies.
• Balance rigour with flexibility in a fast-moving R&D environment.

You don’t need prior quantum experience — curiosity, humility, and the ability to learn quickly matter far more.

This isn’t just about one location. While this opportunity is being promoted in London, the role itself offers the chance to relocate to the US, with full support provided. Our client is building a global team — with opportunities spanning the US, UK, and Asia — and they are focused on one thing: Bringing together exceptional people to build something extraordinary.

Because breakthroughs like this don’t happen in isolation. They happen when the right minds come together, early enough to matter.

• VERY Competitive salary with equity participation.
• Full relocation and visa sponsorship to the US.
• Exposure to one of the most transformative technologies of our time.
• The chance to work alongside world-leading scientists and engineers.
• A career-defining opportunity to shape an entirely new computing paradigm.

Most engineers optimise what already exists. A few get to build what comes next. And a very small number help define what’s even possible.

Our client and our agency are committed to fostering inclusive, diverse environments where different perspectives drive better outcomes. We welcome applications from individuals of all backgrounds and believe innovation is strongest when built by diverse teams.

If you’re ready to step into something ambitious, uncertain, and potentially world-changing — this is your moment. Apply now and start the conversation.
