Top Tech Jobs & Startup Jobs in Boston, MA

Implement and sign off complex digital blocks from synthesis through physical verification in advanced process nodes. Drive full-chip STA and timing closure, power analysis, floorplanning, IO and clock distribution, DRC/LVS cleanup, and functional/timing ECOs. Automate flows with TCL/Python/Shell, collaborate across teams, and work with EDA vendors to resolve tool issues.

The Photonics Technical Lead will create scalable laser solutions for silicon photonics AI communications, collaborating across teams to ensure design feasibility and meet performance specifications.

Lead design verification for integrated digital, analog, and photonic devices using UVM, mixed-signal/AMS methods, RNM, and emulation. Define DV methodology, create reusable testbenches, run block and full-chip verification, integrate analog IP and behavioral models, close coverage and signoff, and collaborate with architects and designers for performance and post-silicon validation.

The Sr./Principal Mixed-Signal Digital Architect will design digital circuits for photonic-based communication, collaborate with teams, and lead product development.

Develop and extend device software and firmware for photonic processors and interconnects. Define control plane, diagnostics, and monitoring; integrate with datacenter administration (CMIS, OpenBMC, DMTF). Implement security, telemetry, virtualization, and remote administration. Debug embedded systems, collaborate across hardware and software teams, and participate in customer engagements to gather requirements.

Define and specify system-level digital architectures for high-speed mixed-signal photonic communication chips. Collaborate with digital, analog, photonic, firmware, and test teams to enable SerDes, ADC/DAC, modulators, and receivers from concept through production. Produce and validate architectural specifications and work with RTL and verification teams to ensure implementation and test alignment.

Design and architect high-speed (50G+) analog/mixed-signal circuit blocks for optical transceivers, collaborate with analog, digital, photonics, and software teams to model and analyze solutions, produce and validate architectural specifications, and represent technical leadership externally.

Design and layout block- and chip-scale silicon photonic circuits from concept through tapeout and bring-up. Collaborate with analog, digital, packaging, product, and architecture teams to floorplan and integrate on-chip photonics, perform layout-driven simulation and verification, troubleshoot performance bottlenecks, improve layout/verification flows and PDKs, and support photonic product development and publications.

Lead STA sign-off and timing closure for silicon-photonics ASICs across process nodes. Develop timing constraints, run full-chip STA, automate ECOs with Tempus/PrimeTime, collaborate with RTL/DFT/architecture teams, and document best practices for synthesis through PnR and tapeout signoff.
