Mixed Signal IC Layout Design Engineer - Contractor at Tenstorrent

Tenstorrent is looking for a Mixed-Signal IC Layout Design Engineer to own a full‑custom layout for high‑performance analog and mixed‑signal IP in advanced FinFET nodes. You’ll translate schematics into manufacturable layouts that hit aggressive performance, power, area, and reliability targets, and integrate these blocks cleanly into larger SoCs.

This role is remote, based out of North America.

We welcome candidates at various experience levels. During the interview process, candidates will be assessed for the appropriate level, and offers will align with that level, which may differ from the one in this posting

Who You Are

• An experienced analog/mixed‑signal IC layout engineer with 5 years experience delivered silicon in CMOS/FinFET nodes. Deep proficiency in Cadence Virtuoso (XL/GXL) or equivalent custom layout environments, including constraint‑driven layout and PCells.
• Strong understanding of CMOS devices, interconnect stacks, and advanced‑node rules, including multi‑patterning, density/fill, and lithography‑driven constraints.
• Fluent in physical verification flows (Calibre, PVS, Assura, etc.) for DRC, LVS, ERC, LPE/RC, DFM, and antenna checks as well as being comfortable designing for matching, coupling/noise, IR/EM, ESD, and latch‑up in mixed‑signal environments.
• Detail‑oriented and organized, able to own complex blocks independently while communicating effectively with distributed design teams.
• Bonus points if you bring experience in advanced FinFET nodes (7/5/3 nm), high‑speed / RF‑adjacent circuits (SerDes, CDR, LNAs, VCOs, RF front‑ends), and scripting (SKILL, Python, Tcl/Perl) to automate layout and verification.

What We Need

• Partner closely with circuit designers to plan and implement full‑custom analog/mixed‑signal layouts for blocks such as PLLs, VCOs, ADCs, DACs, LDOs, bandgaps, comparators, clock generators, and high‑speed I/O. Build optimized floorplans and routing that balance area, parasitics, matching, and congestion for both block‑level IP and top‑level SoC integration.
• Apply best‑practice layout techniques (common‑centroid / interdigitated devices, symmetric differential routing, guard rings, shielding, isolation, dummy devices, etc.) to meet stringent matching, noise, and accuracy specs. Optimize for parasitic R/C, coupling, IR drop, and electromigration to achieve noise, timing, and power targets.
• Run and debug DRC, LVS, ERC, DFM, and antenna checks with Synopsys ICV or Siemens Calibre, driving all violations to closure. Support post‑layout extraction and simulation, iterating layout with circuit designers until full spec closure.
• Leverage Synopsys Custom Compiler and Cadence Virtuoso along with physical verification tool suites, ideally on TSMC and Samsun
