Principal RFIC Engineer / RFIC Team Lead – Optical Engines (M/F/D)

Principle Duties and Essential Functions

• Lead the architecture, design, and validation of high‑speed RFICs (Laser Drivers, TIAs, analog front‑ends) for optical transceivers and optical engines
• Act as technical and functional lead of the RFIC team, providing direction across multiple product programs
• Define RFIC specifications and roadmaps aligned with coherent and direct‑detect optical platforms (100G, 800G ZR / ZR+, 1.6T ZR / ZR+)
• Own technology selection and trade‑offs across SiGe BiCMOS, RF CMOS, and advanced foundry processes
• Drive RFIC development through the full lifecycle: concept → silicon → bring‑up → DVT → PVT → MP
• Ensure RFIC performance against key metrics: bandwidth, noise, linearity, output swing, power, and robustness
• Mentor and technically guide RFIC engineers and junior designers
• Support recruitment and capability building (RFIC design, CAD, layout)
• Contribute to long‑term technology strategy and next‑generation optical engine concepts
• Represent RFIC technology internally and externally (foundries, partners, universities)

Knowledge, Skills and Experience Required

• MSc or PhD in Electrical Engineering, Microelectronics, or related field
• 10+ years’ experience in high‑speed analog / RFIC design
• Proven experience with optical transceiver or optical engine RFICs
• Deep expertise in RFIC and high‑speed analog circuit design, Laser Drivers, TIAs, coherent / high‑speed analog front‑ends
• Noise, linearity, signal integrity, and power optimization
• Strong experience with Cadence design flow (Virtuoso, Spectre, EM tools)
• Experience supporting silicon bring‑up, characterization, and qualification
• Solid understanding of electro‑optic integration with Silicon Photonics
• Demonstrated technical leadership in complex R&D environments
• Ability to balance hands‑on technical work with roadmap and team leadership
• Strong communication skills across disciplines and geographies
• Comfortable working in a matrix, multi‑site organization
