We’re hiring for a Staff/Principal High-Speed Analog/Mixed-Signal Front-End Design Engineer with 10–12+ years of relevant experience to work on next-generation optical transceivers supporting 112–224 Gb/s data rates.

The role will focus on photonic modulator drivers and high-speed TX front ends, together with TIA, CTLE, high-speed slicers and equalization/analog DSP techniques in the RX path. The role will also involve high-speed custom digital logic, including high-frequency clocking, serializers/deserializers, pipeline logic, dynamic/custom logic and timing-critical datapath circuits.

We’re looking for strong transistor-level CMOS design expertise with a focus on very high 3-dB bandwidth, low noise, low jitter, good linearity, robust timing and power-efficient operation in advanced CMOS technologies.

Qualifications

- B.E./B.Tech, M.E./M.Tech or PhD in Electrical/Electronics Engineering, Microelectronics, VLSI or a related field.
- 10–12+ years of hands-on analog/mixed-signal IC design experience, ideally in high-speed SerDes, optical transceivers or wireline interfaces.




- Strong experience in TIA, CTLE, high-speed amplifiers, slicers/comparators, TX drivers, clocking and custom high-speed digital circuits.
- Solid understanding of noise, jitter, bandwidth, stability, equalization, signal integrity and high-speed clock/data timing.
- Experience with advanced CMOS/FinFET technologies, schematic-to-layout interaction, parasitic extraction and post-layout verification.
- Hands-on experience with Cadence Virtuoso/Spectre and high-speed analog/mixed-signal simulation flows.
- Experience with silicon photonics, photonic modulators, photodiodes, SerDes or optical link design would be highly desirable.
- Ability to take ownership from architecture and specification definition through transistor-level design, verification, layout support and silicon debug.
- Strong technical communication skills and ability to work effectively across analog, digital, photonics, layout, package and system teams.
