At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. Our team solves tough, meaningful problems that create a safer, more secure world.

Raytheon has an exciting opportunity for a Senior Principal Semiconductor Technical Lead Engineer to join our III‑V process development team within the Microelectronics/Module Design & Foundry Services Department. In this role, you will work on cutting‑edge gallium arsenide, gallium nitride‑based devices, and III‑V focal plane array fabrication. We are seeking a highly skilled professional with a broad understanding of microelectronics processing, III‑V device characteristics, reliability requirements, MMIC product performance, and failure analysis.

As a Sr. Principal Semiconductor Technical Lead Engineer, you will collaborate across all of engineering work centers in our III‑V semiconductor wafer foundry to manage projects in process development, transition to production, yield improvement, and process sustainment. You will provide subject matter expertise from the semiconductor fabrication perspective on reliability data, failure analysis, DC & RF test methods, MMIC performance, foundry layout, and design rules.

You will also monitor progress, report on milestones, and drive foundry improvements.

The role requires the ability to obtain and maintain a U.S. government‑issued security clearance, with active and existing U.S. citizenship required for clearance.

• Lead, manage, and support both independent and contract research and development projects.
• Develop process development and yield improvement ideas followed by collaboration with Advanced Technology program team throughout the capture, proposal, award and execution phases.
• Provide subject matter expertise on major yield drivers in the semiconductor foundry and serve as the technical interface with programs on MMIC yield loss and product failures at higher‑level assembly.
• Develop a semiconductor technology roadmap to identify and implement next‑generation process technologies, improvements, product yield enhancements, and gaps in equipment capabilities.
• Drive transition to production initiatives of semiconductor technologies and process modules while bridging the gap between process development and MMIC product sustainment.
• Create and maintain schedules for process development and yield improvement initiatives to drive execution on time and within budget.
• Effectively communicate with senior leadership, program management and the customer community on engineering project status and root cause investigations.
• Engage the MMIC and module design teams to develop semiconductor processes that enable product performance.
• Collaborate with cross‑functional teams to understand semiconductor process interaction with MMIC performance and reliability to identify process limitations and areas for improvement.
• Manage engineering investments and improvement initiatives to achieve program cost and schedule, support capacity and technology roadmap objectives.

This 1st shift role will be 100% on‑site and based in Andover, MA.

• Typically requires a Bachelor’s Degree in Science, Technology, Engineering or Mathematics (STEM).
• A minimum of 10 years’ of prior work experience or an advanced degree in a related field and minimum 5 years’ of prior work experience in semiconductor processing techniques including photolithography, dry etching, wet chemistry, metal evaporation, sputtering and backside processing and also knowledge of III‑V device characteristics and MMIC performance.
• The ability to obtain and maintain a U.S. government‑issued security clearance post‑start is required. U.S. citizenship is required for clearance.

• Experience managing and reporting on project schedules and financials.
