Senior RF Engineer

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.
