Job description

Infineon Technologies – IR HiRel

Infineon Technologies – IR HiRel is seeking a technically driven Field Application Engineer to support our growing Aerospace & Defense business. This customer‑facing role sits at the intersection of advanced semiconductor technology and the industry’s most demanding applications—satellite systems, launch vehicles, military avionics, defense platforms, and national laboratory programs.

Your Role

Key responsibilities in your new role

• As the primary technical resource for key accounts, you will guide customers from early design conception through successful product integration. Drawing on Infineon’s portfolio of radiation‑hardened and radiation‑tolerant semiconductors—MOSFETs, GaN power devices, gate drivers, and integrated power ICs—you will shorten development cycles, reduce system cost, and improve the reliability of products built to survive the harshest environments on Earth and in space.
• Own the technical relationship across the full sales cycle—from early design engagement through design win capture and program ramp.
• Partner with account managers to identify socket opportunities, build block diagram‑aligned solution proposals, and position Infineon’s rad‑hard and rad‑tolerant portfolio competitively.
• Deliver technical presentations, application training, and design reviews tailored to the constraints of space and defense programs.
• Provide pre‑ and post‑sales support including schematic review, PCB layout guidance, and system‑level performance validation for designs utilizing GaN, Si MOSFETs, gate drivers, and power ICs.
• Validate customer applications in radiation environments, supporting derating analysis, SEE mitigation strategies, and TID margin assessments.
• Advise on product selection across rad‑hard and plastic rad‑tolerant product lines for GEO, MEO, LEO, and defense environments.
• Guide customers through applicable qualification standards including MIL‑PRF‑38535, MIL‑STD‑750, and JEDEC space standards.
• Capture and communicate customer requirements to product and marketing teams to influence roadmap development.
• Provide technical win/loss insight and contribute to the internal opportunity pipeline.

Your Profile

Qualifications and skills to help you succeed

• Bachelor’s degree or higher in Electrical Engineering, Computer Engineering, or related discipline.
• 5+ years in a Field Application, systems, or applications engineering role supporting power electronics or semiconductor products.
• Demonstrated expertise in power switching topologies and high‑frequency power supply design using GaN and/or Si MOSFET technology.
• Experience performing design reviews across schematics, PCB layout, and system‑level performance for customer applications.
• Strong communicator with the ability to engage credibly at both the engineering and program management level.
• Self‑directed and organized, with the ability to manage multiple high‑priority accounts simultaneously.
• Experience with Aerospace & Defense market is a plus.
• Experience with space‑grade memory products (SRAM, Flash) is a plus.

Wage range: Washington DC and Andover, MA: Minimum $127,800 per year, maximum $175,800 per year. All employees eligible to participate in an incentive plan.
