Application Specific Integrated Circuit Design Engineer

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.
