About us
Salience Labs is building an industry-defining approach to optical circuit switching for AI infrastructure, engineered for real latency reduction and cost savings. We're moving towards real-world deployment, and joining at this stage means genuine ownership over that next chapter, working alongside a highly technical team on one of the most consequential problems in AI infrastructure today.
About the Role
We’re looking for a Physical Verification Engineer to drive DRC/LVS signoff for our integrated circuit and photonic integrated circuit (PIC) designs. You’ll work at the intersection of electronic and photonic design, running and debugging verification flows against foundry PDKs and helping keep our tapeouts clean.
What You’ll Do
Run and debug physical verification (DRC, LVS, extraction) on IC and photonic IC layouts
Debug LVS/DRC discrepancies, including port mismatches, hierarchy mismatches, and device recognition issues
Read, manipulate, and QA GDS/OASIS layout data
Maintain and extend verification runsets and rule decks
Build Python/Tcl/shell tooling to automate verification flows and triage error reports
Maintain verification libraries and runsets under version control, with controlled release processes
Handle third-party and foundry IP with care, following licensing terms
Work with design, layout, and CAD teams to close out verification issues ahead of tapeout
Document known issues, workarounds, and runset changes
What You Bring
Required
3+ years of hands-on physical verification experience in IC design
Practical experience with Siemens Calibre and/or Synopsys ICV for DRC/LVS signoff
Experience with custom/analog layout tools such as Cadence Virtuoso or Synopsys CustomCompiler
Strong working knowledge of GDS/OASIS formats and LVS concepts
Proficiency with Linux and scripting in Python, Tcl, or shell
Experience managing rule decks, runsets, or libraries under version control (e.g., Git)
Ability to independently debug complex hierarchical netlist and layout issues
Strong written communication for documenting root causes and fixes
Nice to have
Photonic IC verification experience
Experience with Verilog/SystemVerilog netlists
Exposure to foundry PDK qualification
Experience building internal automation to scale verification
