Electronics Systems Engineer

The Role:

We’re looking for a hands-on Electronics Engineer who loves solving complex problems and bringing ambitious technology to life. You’ll be central to designing, prototyping, and optimising advanced electronics for cold atom and quantum systems.

This isn’t a “follow the manual” job, you’ll help shape your role, work across disciplines, and tackle real engineering challenges head-on. If you thrive in a start-up environment, adaptable, innovative, and ready to persevere, this role is for you.

What You'll Do:

• Collaborate with scientists & engineers to define system requirements for quantum technologies.

• Design, develop & test low-noise analog and digital circuits.

• Implement control and data acquisition systems for cutting-edge experiments.

• Debug & optimise complex electronic hardware for reliable performance.

• Integrate and test next-generation quantum devices.

• Continuously improve hardware & software solutions.

What We Are Looking For:

• BSc/MSc in Electrical/Electronics Engineering (PhD or Systems Engineering background is a plus).

• 3+ years’ experience in electronics design and prototyping for high-performance systems.

• Strong skills in analog & digital circuit design, PCB layout, and prototyping.

• Experience with GHz RF circuits highly desirable.

• Background in cold atom, FPGA, or quantum technologies (atomic clocks, sensors, computing) is a big advantage.

• Proficiency with relevant programming languages & design tools.

• Excellent problem-solving and communication skills.

• Start-up mindset: proactive, flexible, and hands-on

What We Offer:

Salary: £40k + Bonuses
Milestone bonuses: 2x per year (June & December, ~£3.4k each)
Share options
Enhanced pension scheme
Overseas travel opportunities

Benefits:

• 26 days annual leave + company closure over Christmas/New Year

• Flexible hours (10am-4pm core hours)

• Regular team outings, training & knowledge-sharing sessions (every 2 weeks)

• Annual performance & salary review

About Us:

At Aquark Technologies, we’re on a mission to reshape the future of sensing and quantum computing. Spun out from the University of Southampton, we’re building the world’s most portable, high-performance miniaturised cold atom traps, pioneering devices that will unlock new possibilities in quantum technology.

Following a major research contract win, we’re expanding our team. This is your chance to join a fast-moving start-up, work on cutting-edge science and engineering, and make a tangible impact.
