Exempt: Yes

Leads the development of high-performance mmWave RFICs for FR2/FR3 radar and 5G applications. The role combines hands-on circuit design with technical leadership and end-to-end ownership of the Tx signal chain, including architecture, implementation, verification, characterization, and production ramp. The successful candidate will lead and mentor engineers while driving solutions that meet EVM, emissions, output power, gain, efficiency, linearity, beamforming, calibration, and reliability requirements.

RESPONSIBILITIES

• Lead the architecture, design, layout, integration, verification, characterization, and commercialization of mmWave RFICs, with primary ownership of the Tx signal chain from baseband/IF through mixers, LO distribution, drivers, power amplifiers, gain control, beamforming, detection, and calibration.

• Define Tx budgets and allocate margin across IC, package, PCB, antenna, process, voltage, temperature, and calibration conditions; identify and close performance gaps through simulation and measurement.
• Provide hands-on technical leadership, conduct design and data reviews, resolve cross-functional issues, mentor engineers, and improve design processes, checklists, and execution quality.
• Drive RFIC-package-PCB-antenna co-design using circuit, EM, statistical, mixed-signal, reliability, and electrothermal simulation, including matching, coupling, power handling, thermal effects, beamforming accuracy, and conducted/OTA emissions.
• Own the IC design and verification flow, including biasing, power management, calibration, PDK/foundry interaction, design documentation, production variation, yield, validation, and reliability analysis.
• Partner with Test and Product Engineering to define characterization and ATE strategies, production observability, built-in test features, trims, guard bands, and high-correlation Tx measurements.
• Support silicon debug, customer issues, field failures, yield improvement, and product ramp in collaboration with Systems, Applications, Antenna, Package, PCB, Firmware, Software, Test, and Manufacturing teams.
• Manage technical risks, priorities, schedules, and deliverables; communicate architecture decisions, tradeoffs, and status clearly to program teams and senior management.
• Contribute to technology roadmaps and intellectual property that advance future products.

QUALIFICATIONS

• M.S. or Ph.D. in Electrical Engineering or a related field, with 10-15 years of RF/analog/mixed-signal IC design experience and demonstrated leadership of complex RFIC programs.
