I’m supporting a key client based at their HQ in Sedgefield — a high-growth RF/microwave technology business delivering advanced connectivity solutions into space, defence, telecoms and critical communications sectors. They design and manufacture high-performance RF, microwave and mmWave hardware for mission‑critical systems, and they’re scaling quickly following strong revenue growth and multiple flagship programme wins.
They’re now looking to add a Senior RF Engineer to strengthen their core RF/mmWave capability at the Sedgefield HQ. This Senior RF Engineer will take a leading role in designing, developing and validating high-performance RF/mmWave circuits and subsystems, collaborating closely across engineering teams and playing a key part in delivering complex new products.
Role Overview – Senior RF Engineer
You’ll be responsible for robust RF/microwave design delivery, hands‑on test work, technical problem‑solving, and supporting the wider engineering roadmap across concept, prototype and production.
Key Responsibilities
Technical
- Lead the design, simulation and development of RF and mmWave circuits, components and subsystems
- Perform RF system analysis, optimisation and troubleshooting on complex designs
- Execute RF measurements, characterisation and validation across prototypes and production hardware
- Produce high‑quality technical documentation including design reports, test plans and results
- Ensure designs meet specification, standards and customer requirements
- Contribute to product and technology roadmaps with innovative RF ideas
- Provide technical input into RFQs, proposals and customer discussions when required
Project and product delivery
- Work with project managers and engineering leads to deliver designs to quality, cost and schedule
- Support the transition of concepts through prototyping into volume manufacturing
- Collaborate with operations/process engineering to ensure strong manufacturability and yield
- Assist in identifying and mitigating technical risks throughout development
- Collaboration & Communication
- Work closely with electronics, mechanical, software and systems engineering teams
- Provide technical support to internal stakeholders and customers
- Present technical updates and design reviews as required
Scope may evolve as programmes and customer needs develop.
