Principal RFIC Engineer – RFIC Team Lead, Optical Engines
AdtranPrincipal RFIC Engineer leading the design and validation of high-speed RFICs for optical engines. Focused on technical leadership and development lifecycle across multiple product programs.
About the role
Key responsibilities & impact- 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)
