As a Senior Electronics Systems Engineer, you will apply your expertise in mixed‑signal electronic design and system‑level integration to support the development of complex, high‑performance products.

You will:

• Design, develop and test analogue, digital and mixed‑signal electronics across the full product lifecycle for new and legacy products and test equipment.
• Support hardware integration testing, troubleshooting and problem solving.
• Use E‑CAD tools for schematic capture, PCB layout and circuit/PCB simulation.
• Work closely with Systems, Software, Mechanical and other engineering disciplines to deliver integrated solutions.

What You Must Have

• A minimum 2:1 Bachelor’s degree in Electronics Engineering or a closely related discipline.
• A strong theoretical understanding of analogue electronics.
• Experience integrating sensitive analogue circuitry with high‑speed digital devices such as FPGAs, DSPs and microprocessors.
• Experience designing precision circuitry, including op‑amps, DACs, ADCs and voltage references.
• An understanding of control theory and open and closed‑loop systems.
• Experience using E‑CAD systems for schematic capture, PCB layout and circuit/PCB simulation.

Skills & Experience We Value

We would also be interested in experience in one or more of the following areas:

• Xpedition, HyperLynx, LTSpice/AMS or similar tools.
• VHDL/Verilog architectural design, coding and simulation, particularly with Xilinx or Microchip technologies, including SoC.
• Embedded C/C++ for integration and problem solving.
• MEMS sensor technology.

What We Offer

• Competitive salary and benefits package.
• Flexible working options.
• Excellent 2:1 matched pension contribution (up to 10%).
• Private health insurance and life assurance.
• 25 days annual leave plus the ability to buy or sell up to 5 more.
