Principal Photonics IC Design Engineer

NVIDIA has continuously reinvented itself over two decades.

Our invention of the GPU in 1999 fueled the growth of the PC gaming market, redefined modern computer graphics, and revolutionized parallel computing.

More recently, GPU deep learning ignited modern AI — the next era of computing.

NVIDIA is a “learning machine” that constantly evolves by adapting to new opportunities that are hard to solve, that only we can address, and that matter to the world.

This is our life’s work, to amplify human creativity and intelligence.

Make the choice and join us today!

NVIDIA's Mixed-Signal Design (MSD) Photonics team is building the next generation of co-packaged optical interconnects to power the world's most advanced AI supercomputers.

We are looking for a Principal Photonics IC Design Engineer to serve as the technical lead owning our photonics integrated circuit (PIC) product — from architecture definition through production tapeout and silicon validation.

What you will be doing:

Own end-to-end PIC product delivery: architecture, design, layout, DRC/LVS verification, tapeout, and post-silicon validation on advanced silicon photonics platforms

Lead cross-functional execution across photonic device, analog/mixed-signal, packaging, and systems teams

Drive tapeout schedules, define design milestones, and resolve critical path issues across multiple concurrent PIC programs

Architect optical transceiver PICs integrating modulators, photodetectors, wavelength multiplexing, waveguides, and optical couplers for high-speed and/or DWDM applications

Define and improve PIC design methodology, automation (e.g., scripted DRC, parameterized cells), and verification flows in Cadence and related EDA tools

Mentor and technically guide a team of photonics designers; set technical direction for the photonics PIC roadmap

PhD in Electrical Engineering, Physics, Applied Physics, or a closely related field with emphasis on integrated photonics, silicon photonics, or photonic device physics (or equivalent experience).

8+ years of industry experience in photonics IC design, with demonstrated progression into technical leadership roles

Deep hands-on expertise with Cadence design environment (Virtuoso, PCell development, SKILL scripting) for photonic IC layout and simulation

Proven track record of production tapeouts — you have personally driven PICs from design through GDS signoff on a foundry silicon photonics process

Strong understanding of photonic device physics: waveguides, passive/active components, ring/MZI modulators, photodetectors, optical couplers

Demonstrated technical leadership: setting project scope, making architecture tradeoffs, driving cross-team alignment, and delivering on schedule

Ways to Stand Out From the Crowd:

Experience with high-speed (>50 Gbaud) optical modulator or receiver PIC design for datacom/telecom applications

Experience with DWDM PIC architectures (MUX/DEMUX, multi-channel transceivers, wavelength tuning)

Familiarity with co-packaged optics (CPO) system requirements and advance packaging integration

Experience with photonic circuit simulation and CAD tools (Ansys Lumerical, ZeMax, Cadence, MATLAB, Python and Verilog-A) and electromagnetic solvers (FDTD, FDE, EME)

Track record of publications and/or patents in silicon photonics

You will also be eligible for equity and benefits.
