DFT Lead

Job Title DFT Lead About The Role Avicena is developing high-speed parallel optical links built from arrays of microLED transmitters and photodetector receivers. We are looking for a DFT Lead to own the test architecture of our mixed-signal ASIC, from scan and BIST through analog test access and production test delivery. You will define the strategy, implement and verify it, and work with product/test engineering to bring it up on the tester. Key Responsibilities Own the DFT architecture and strategy for a mixed-signal ASIC, including coverage and test-time targets.Implement scan insertion and compression, and generate ATPG patterns for stuck-at, transition and path-delay faults.Implement memory BIST and repair, and IEEE 1149.1/1687 access for test and instrument control.Define link-level test features with the design teams: loopback modes, PRBS generators and checkers, and analog observability and trim access.Verify DFT logic and patterns with gate-level simulation, and close test-mode timing with the implementation team.Deliver ATE patterns and support tester bring-up with product/test engineering.Diagnose silicon failures and support yield learning and test-time reduction.Grow DFT capability as the team expands. Qualifications Required BS or MS in Electrical or Computer Engineering with 10+ years of DFT experience on production ASICs.Hands-on expertise with Siemens Tessent or Synopsys TestMAX/DFTMAX/TetraMAX.Scan compression, ATPG, memory BIST and JTAG/IJTAG.Gate-level simulation of test patterns and test-mode timing closure.ATE bring-up and silicon failure diagnosis. Preferred DFT for mixed-signal chips with analog test access.Test of high-speed I/O, including loopback, PRBS and margining; IEEE 1149.6.Hierarchical DFT.Yield analysis and diagnosis tools.Experience leading DFT engineers. Key Competencies Ownership: accountable for test quality from architecture to production.Pragmatic: balances coverage, area and test time.Collaboration: works across design, implementation and test engineering.Problem solver: methodical in silicon debug.
