About the Role

Lead the architecture, design, and validation of high-speed RFICs for optical transceivers and engines. Provide technical and functional leadership to the RFIC team, defining specifications and roadmaps for advanced optical platforms.

Responsibilities

  • 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)

Requirements

  • 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
  • Deep expertise in Laser Drivers, TIAs, coherent / high‑speed analog front‑ends
  • Deep expertise in 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
