Co-designed chips, racks, and software to push the pareto frontier to best-in-class throughput and interactivity. Backed by Kleiner Perkins and Sequoia.
About the role
Etched is looking for an exceptional Optical Systems Engineer to join our team. In this role, you will own the definition and implementation of the optical interconnect architecture for our next-generation accelerator systems and help us scale our manufacturing capabilities. Lead optical link architecture and system design for Etched's accelerator systems
What they're looking for
- 5–10 years of experience in optical interconnect, transceiver, or photonic system design and development for high-density compute systems
- Expertise across advanced optical interconnect architectures, including Co-Packaged Optics (CPO), Near-Packaged Optics (NPO), Optical Compute Interconnect (OCI), Linear Pluggable Optics (LPO), and emerging form factors (XPO)
- Clear understanding of architectural tradeoffs across these technologies: energy-per-bit, bandwidth density, reach, latency, serviceability, and reliability
- Strong fundamentals in optical link engineering, including link-budget analysis, IL/RL, OSNR, eye diagrams, jitter, BER, and FEC margining
- Working knowledge of laser sources, modulators, TIAs, and DSPs/retimers
- Knowledge of high-speed host interfaces such as 100G/200G-per-lane PAM4
