About the role

We’re representing a venture-backed silicon photonics startup building high-performance systems for next-generation AI infrastructure. They’re looking for an ASIC/Digital Design Engineer to help architect and implement high-bandwidth silicon systems that connect compute logic with optically coupled memory and chiplet-based architectures. Experience with: ASIC digital design (RTL in Verilog / System Verilog) with tapeout experience in advanced nodes (e.g., 7nm and below preferred)Microarchitecture design of high-performance digital systems (pipelines, interconnects, memory hierarchies)High-speed data movement architectures (NoC, interconnect fabrics, streaming datapaths)High-speed I/O interfaces (PCIe, Ethernet, CXL, SERDES, DDR/HBM, or similar)Memory subsystem design (coherence, buffering, latency optimization, bandwidth scaling)ASIC integration across multiple IP blocks (3rd party IP, internal subsystems, interface bridging)Timing closure, PPA tradeoffs (power, performance, area) in large-scale SoCs or chiplet-based designs System-level thinking across compute + interconnect + memory boundaries
Nice to have: Experience with chiplet architectures or multi-die / heterogeneous integration Background in network processors, AI accelerators, or HPC-class SoCsExposure to optical interconnects, silicon photonics, or high-speed Ser Des ecosystems Experience bridging RTL ↔ physical design awareness (timing, floorplanning constraints, congestion-driven architecture decisions)Exposure to AI/ML workloads from a hardware efficiency / data movement perspective (not algorithm development)Remote-friendly (US) with preference for Bay Area proximity.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
