Senior RF/Microwave Design Engineer

As a Senior RF/Microwave Design Engineer here at Honeywell, you will play a key role in the design, development, and delivery of advanced engineering solutions that drive innovation, performance, and reliability across critical systems. You will work within cross-functional teams on complex projects that support next-generation products and technologies.

In this role, you will contribute to the development of sophisticated Software Defined Radio solutions for space communications systems, ensuring robust design, integration, and performance of components and subsystems. Your strong technical expertise and hands-on approach will be essential in delivering high-quality, reliable systems that meet demanding mission and customer requirements. You will report directly to our Engineering Manager, and you’ll work out of our Edinburgh, UK location on an on-site work schedule.

Join a company that's reintroducing itself to the aviation community we've helped advance for more than a century. At Honeywell Aerospace (NASDAQ: HONA), we're launching as an independent, publicly traded aerospace and defense company built on a legacy of operational excellence and mission-focused execution.

Our new brand identity pairs that heritage with real momentum, as we build technology that helps pilots navigate with confidence, aircraft operate more efficiently, and operators stay ahead of change. With our systems on board 90% of the world's aircraft, your work here has reach that's rare to find anywhere else.

Focusing on our customers, investing in innovation, and building a culture of accountability and performance is how we're shaping what comes next.

Every horizon. Every mission. Every day.
