Job Description

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 / SystemVerilog) 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 SoCs
• Exposure to optical interconnects, silicon photonics, or high-speed SerDes 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.
