About us

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.

The role

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.

About you

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.

Training and development

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 mentor a junior colleague or be mentored by someone more experienced, depending on what will best support your growth.

Your learning will draw on the broad expertise across the team, and you'll also be encouraged to identify additional courses or learning opportunities that help deepen your knowledge in specific areas.

Whether your goal is to deepen technical expertise or broaden your skill set, we're committed to giving you everything you need to succeed.

Rewards and benefits

We offer a competitive salary of between £48,782 and £58,194, dependent on your skills and experience. This includes a concessionary payment of £2,658 and a skills payment. All successful candidates receive a one-off recruitment bonus of £3,500. Other benefits include:

  • 25 days' annual leave, automatically rising to 30 days after 5 years' service, and an additional 10.5 days of public and privilege holidays
  • opportunities to be recognised through our employee performance scheme
  • an interest-free season ticket loan
  • an excellent pension scheme
  • a cycle to work scheme
  • facilities such as a gym, restaurant, and on-site coffee bars (at some locations)
  • paid parental and adoption leave
  • Equal opportunities

At GCHQ diversity and inclusion are critical to our mission. To protect the UK, we need a truly diverse workforce that reflects the society we serve. This includes diversity in every sense of the word: those with different backgrounds, ages, ethnicities, gender identities, sexual orientations, ways of thinking, and those with disabilities or neurodivergent conditions. We therefore welcome and encourage applications from everyone, including those from groups that are under-represented in our workforce such as women, those from an ethnic minority background, people with disabilities and those from low socio-economic backgrounds.
