Quantum Hardware Engineer

Your mission

As we expand our international presence and establish our operations in the United Kingdom, we are looking for a (Senior) Quantum Hardware Engineer to join us at this exciting stage of our growth.

You will play a central role in bringing our quantum systems from concept to reality. Working at the intersection of atomic, molecular and optical (AMO) physics and engineering, you will take ownership of critical subsystems within our quantum computing platform, driving them from design through integration and operation.

As part of our growing UK team, you will collaborate closely with colleagues across our international locations, combining cutting-edge research with practical engineering to develop robust, scalable quantum hardware.

This is an opportunity to contribute to the development of our quantum technology while helping shape planqc's engineering presence in the UK.

We are looking for experimental physicists who enjoy building complex systems, taking ownership and working in an ambitious, highly collaborative environment.

Your responsibilities

• Take ownership of a key subsystem of our neutral-atom quantum computer, such as optical subsystems, laser distribution or quantum processor operation.
• Design, build and optimise high-performance experimental setups for neutral-atom quantum systems.
• Integrate your subsystem into the wider quantum computing platform, ensuring reliable and consistent operation.
• Collaborate closely with colleagues across physics, software, mechanical and electrical engineering to deliver integrated technical solutions.
• Drive continuous improvements in system stability, performance, reliability and scalability.
• Contribute to system architecture decisions and technical roadmap discussions.
• Work closely with our international engineering teams, sharing knowledge, expertise and best practices.
• Contribute to the development of our UK engineering activities as we establish and grow our local presence.

What you bring

• A PhD in AMO physics, experimental quantum physics or a closely related discipline, or equivalent relevant research experience.
• Strong hands-on experience with lasers, optical setups and experimental quantum systems.
• Demonstrated experience designing, building, troubleshooting and operating complex experimental setups.
• Technical expertise in one or more of the following areas:
  • Optical tweezer arrays and atom arrays
  • Rydberg atoms or alkaline-earth atoms
  • Ultracold atoms, trapped ions or ultra-high vacuum (UHV) systems
  • High-numerical-aperture imaging and addressing systems
  • Frequency- and amplitude-stabilised laser systems
• Ability to take ownership of complex technical challenges and drive solutions independently.
• Strong analytical and problem-solving skills, combined with a practical, hands-on approach.
• Confidence working collaboratively across different technical disciplines and international teams.

Nice to have

• Programming experience, particularly Python for experiment control, automation or data analysis.
• Experience with electronics, control systems or laboratory automation.
• Mechanical design experience, including CAD.
• Experience transitioning experimental research setups into reliable, scalable engineering systems.
• Previous experience in a commercial R&D, deep-tech or startup environment.
• Experience collaborating across geographically distributed engineering teams.

What characterizes you

• You are a builder. You enjoy turning ambitious scientific ideas into working experimental systems.
• You take ownership. You are comfortable making decisions, solving problems and driving technical topics forward.
• You are curious and pragmatic. You combine scientific rigour with a hands-on, solution-oriented mindset.
• You are collaborative. You enjoy working with specialists from different disciplines and sharing knowledge.
• You are adaptable. You feel comfortable in an evolving environment where processes and structures are still developing.
• You are motivated by impact. You want to see your work contribute directly to the development of real-world quantum technology.
