This job is brought to you by Jobs/Redefined, the UK's leading over-50s age inclusive jobs board.

A salary range of £48,782 to £58,194, including a concessionary payment of £2,658 and a skills payment. The final amount depends on your skills and experience. You'll also receive a one-off recruitment bonus of £3,500 (£1,750 on arrival and £1,750 on successful completion of probation)

We offer a range of flexible working patterns, including offering full-time, part-time, and compressed hours to support your individual needs. While homeworking isn't possible due to the nature of the role, we can offer flexibility, such as variations in start and finish times, where business needs allow.

GCHQ is an intelligence, cyber, and security agency with a mission to keep the UK safe. We use cutting‑edge technology, ingenuity and partnerships to identify, analyse and disrupt threats. Working with our intelligence partners MI5 and MI6, we protect the UK from terrorism, cyber‑attacks and espionage. At GCHQ you'll do varied and fascinating work in a supportive and inclusive environment that puts the emphasis on teamwork.

As a Senior Electronic Engineer, working alongside other engineers, you'll design, test and integrate analogue electronics and hardware that keep our teams at their best. The role spans the entire project lifecycle, from design to delivery, focusing on identifying and addressing challenges. Key responsibilities include designing component‑level analogue electronics and hardware systems with Electromagnetic Compatibility (EMC) in mind. You'll also carry out Printed Circuit Board (PCB), hardware, and system‑level testing and verification.

If successful, you could be producing high‑quality design and test documentation, contributing to forward‑looking analogue electronics research, developing and maintaining scripts such as BASH/C wrapper and helper tools, identifying and mitigating risks, and supporting hardware integration across different systems.

Depending on your experience, developing and contributing to embedded Linux solutions is also possible as part of the role.

We're seeking engineers with experience in component‑level analogue electronic design and who have taken projects from concept through to delivery.

Key skills and experience include:

• Proficiency in component‑level analogue electronic design, including power supplies and complex discrete electronic circuits
• Experience with simulation tools such as LTSpice, and schematic capture tools like Mentor, Pulsonix, or Altium
• Familiarity with a wide range of electronic test equipment and a good understanding of EMC requirements and design principles

You’ll be a proactive and adaptable individual, able to engage with internal and external customers, and work effectively with other organisations. You’re able to spot opportunities, learn new skills quickly, and drive projects forward.

Additionally, experience with scripting and basic coding (BASH, Python, or C on microcontrollers), and familiarity with Linux and networking, is desirable but not essential. We’ll provide comprehensive training to ensure you have the tools and knowledge you need to succeed.

The first three days of your time with us will be dedicated to a comprehensive department induction, designed to help you understand how things work and who does what.

At GCHQ, we’re committed to your growth and development. You’ll have dedicated time and space for continuous learning, experimentation, and improvement, with up to 30% of your time available for personal development.

We’ll support professional development, including opportunities to gain professional accreditations if that’s the route you’d like to explore. You’ll also be assigned a buddy who’ll provide guidance and support throughout your time with us.

Your training and ongoing support will be tailored to you, as you’ll be working within a small team where development can be shaped around your needs. While most training is delivered in‑house, we also offer regular opportunities to top up your knowledge through external training providers.

You’ll have the chance to either…
