MMWave Beamformer Apps Engineer for 5G/SATCOM

Sivers Semiconductors UK; Town of Sweden (NY); On-site; USD 110,000 - 180,000; Full time

Job summary

Sivers Semiconductors UK is seeking an Applications Engineer to support mmWave beamformer ICs and active antenna arrays for 5G, SATCOM, radar, and sensing applications. You will bridge product design teams and customers to integrate advanced ICs into real-world systems.

The role emphasizes RF/microwave expertise, hands-on measurement with test gear, and collaboration across RF, mixed-signal, and system domains. Join a global team shaping next-generation wireless technologies.

Qualifications

• MS in Electrical Engineering (PhD preferred) with a focus on RF/mmWave circuits or systems.
• 3–8 years of experience in RFIC design, antenna arrays, or system integration.
• Strong understanding of beamforming architectures, RF measurements, and phased‑array calibration.
• Hands-on experience with network analyzers, spectrum analyzers, signal generators, and antenna range testing.
• Excellent written and verbal communication skills; able to work effectively with cross-functional teams and customers.

Responsibilities

• Serve as the primary technical contact for customers integrating mmWave beamformer ICs into antenna arrays.
• Develop and validate reference designs, evaluation boards, and calibration scripts for beamforming and gain/phase control.
• Characterize array-level performance (EIRP, EVM, beam patterns, linearity, noise figure) across temperature and frequency bands.
• Support system-level design including RF signal chains, LO distribution, power management, and digital control interfaces (SPI/I²C).
• Assist in debugging and root-cause analysis of performance issues during customer bring-up and production ramp.
• Collaborate with internal design and test engineers to provide feedback on product specifications, firmware, and test automation.
• Produce application notes, design guidelines, and training material for customers and field support teams.
• Contribute to customer demos, trade shows, and design-win activities in collaboration with marketing and business development teams.
