Mixed Signal IC Layout Design Engineer - Contractor

About the role

Tenstorrent is looking for a Mixed-Signal IC Layout Design Engineer to own 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, and welcomes candidates at various experience levels.

Requirements

• 5+ years of experience delivering silicon in CMOS/FinFET nodes as an analog/mixed-signal IC layout engineer.
• 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.
• 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: 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.

Responsibilities

• 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 Samsung FinFET processes from 12 nm down to 2 nm.
• Develop and use layout methodology and automation (Python, Tcl, SKILL, etc.) to raise quality and productivity for the broader team.

What You’ll Learn

• How to implement and integrate high-speed, high-precision analog/mixed-signal IP into complex SoCs in cutting-edge FinFET technologies.
• Advanced techniques for balancing PPA (performance, power, area) in mixed-signal layouts under tight matching, noise, and reliability constraints.
• Practical exposure to state-of-the-art verification and DFM flows (R/C extraction, EM/IR, antenna, advanced fill) across leading foundry processes.
• How to scale your impact via methodology and automation, building scripts and flows that improve consistency, turnaround time, and silicon quality for the entire layout team.
