Senior MMIC Engineer

An exciting opportunity has arisen with one of our long-standing clients, a specialist in high-frequency RF and mmWave solutions for mission-critical communications and sensing applications. With decades of experience in designing cutting-edge components such as SSPAs, filters, and transceivers, they serve a wide range of industries including satellite, defence, and advanced telecoms. We’re looking for a Senior MMIC Engineer to join their engineering group, collaborating closely with RF, electronics, and systems engineers to drive the design and development of advanced MMIC-based products. This is a key technical role focused on RFIC/MMIC design using GaAs, GaN, and InP technologies, supporting applications from 37GHz up to 115GHz and beyond. Key Responsibilities: Design and layout of MMICs including LNAs, gain blocks, power amplifiers, up/down-converters, multipliers, and variable attenuators across multiple process technologies. Select appropriate MMIC processes based on application requirements and performance trade-offs. Conduct simulations and hands-on testing to validate designs, working with in-house labs and external semiconductor foundries. Prepare and review comprehensive design documentation, ensuring alignment with technical, quality, cost, and manufacturing goals. Collaborate with other engineering teams during design reviews to reduce risk and improve reliability. Perform thermal analysis and MTBF assessments. Manage fab submissions, coordinate with foundries, and support prototype and production testing. Identify and document novel IP arising from design work with potential for patent applications. What We’re Looking For: A relevant engineering degree (MSc or PhD preferred). Experience in MMIC/RFIC design within the semiconductor or RF industry. Hands-on experience designing MMIC amplifiers, frequency converters, and related RF circuits using GaAs or GaN HEMT technologies. Strong measurement skills, including wafer probing and use of advanced RF lab equipment. A solid understanding of various semiconductor technologies and their impact on RFIC/MMIC performance. Familiarity with RF/microwave system-level design is advantageous. Previous engagement with external foundries and understanding of their workflows is beneficial. Why Apply? Flexible hybrid working options. Generous pension and life assurance schemes. Training & development support. Competitive holiday allowance. Opportunity to contribute to advanced mmWave products used globally. If you’re an experienced Senior MMIC Engineer looking for a role where you can work on complex, high-frequency designs with a technically strong and supportive team, please reach out to Zac Taylor at IC Resources.
