Test Engineer

• Partner with external design partners and internal hardware engineers to define and execute DFT strategy for each chip program
• Generate, validate, and deliver ATPG patterns including scan, MBIST, JTAG, and embedded memory read and write sequences
• Develop and maintain STIL and PDL test program files for ATE execution
• Drive DFT sign-off deliverables and resolve pattern-level issues in coordination with external partners
• Support setup pattern generation including power-up and power-down sequences, DFT entry sequences, and test mode initialization
• Understand and define power rail sequencing requirements for ATE execution to ensure safe device bringup

• Develop and debug test programs on ATE platforms including Advantest and Teradyne systems
• Execute first silicon bringup on new tapeouts in partnership with hardware engineers and OSAT test teams
• Characterize device behavior across voltage, temperature, and frequency corners
• Support load board bring-up and interface hardware validation
• Define and manage test flows including wafer probe, final test, and bin sort
• Understand test time optimization strategies such as pattern flow sequencing to minimize unnecessary power cycles

• Serve as the primary test engineering interface with OSAT partners and test houses
• Manage test program handoff to OSAT including documentation, qualification, and acceptance criteria
• Coordinate pattern delivery between design partners and OSAT to ensure format compatibility across STIL and SVF as required
• Track and analyze yield data from probe and final test, escalate anomalies, and drive corrective actions
• Support die traceability and OTP programming flows in production bin sort
• Coordinate with supply chain and operations on test capacity planning and lot scheduling

• Own test engineering across multiple active chip programs simultaneously
• Build scalable test infrastructure and documentation that carries forward to future programs
• Contribute to DFT reviews, tapeout checklists, and test escape analysis
• Help define and mature internal test engineering capabilities over time

• 5+ years of semiconductor test engineering experience in a fabless or IDM environment
• Hands-on DFT experience including scan insertion, ATPG, MBIST, and JTAG boundary scan
• Experience generating and validating STIL patterns and working with test pattern delivery packages
• ATE test program development experience on Advantest or Teradyne platforms
• Experience supporting wafer probe and final test at an OSAT or test house, including load board bringup
• Familiarity with power sequencing requirements and DFT entry flows for ATE test program development
• Ability to work directly with external design partners and OSAT suppliers to coordinate pattern delivery and test execution
• Strong written and verbal communication skills - this role requires ongoing collaboration with external partners across multiple time zones

• Experience with embedded memory test including characterization and programming of non-volatile memory technologies
• Exposure to high-speed serial interface test such as memory interfaces or camera and display interconnect protocols
• Familiarity with DFT tools from major EDA vendors
• Experience at a fabless startup or small team where test engineering scope is broad
• Exposure to leading-edge process nodes at 28nm or below
• Experience with ATE yield analysis and test time optimization
• Scripting ability in Python or Perl for data analysis and test automation
• Experience generating VCD from RTL simulation and porting to STIL format

We offer a competitive base salary for this role, generally ranging from $150,000 to $190,000, plus a 10% annual bonus, meaningful equity, and comprehensive benefits. Final compensation will depend on experience, level, and location, with flexibility for the right candidate.
