Retym, Inc Tech Stack

Coherent DSP semiconductors for AI data center interconnects

Semiconductor Manufacturing Cupertino, CA 51–200 employees Founded 2021 Privately Held

Retym builds DSP silicon for optical networking in AI data centers—the connectivity layer between compute nodes. The stack (SystemVerilog, Verilog, Synopsys, Cadence, TSMC, SerDes, HFSS) reveals deep analog-mixed-signal and physical-design maturity; projects span ADC/DAC development, RTL-to-GDS flow ramp, and system-level test frameworks for a coherent optical transceiver. Hiring is heavily senior engineering (33 of 39 roles) across three countries, suggesting a post-Series-A product-in-flight scaling phase—pain points confirm this: timing closure, complex IP integration, distributed-team coordination, and low-power constraints are all signature stress points of first-silicon bringup.
