Re-posted 7 hours ago

Job description

Efficient Computer is a fabless semiconductor startup headquartered in Pittsburgh, PA, building energy-efficient processors for edge compute, embedded AI, and high-performance applications. Our team designs, tapes out, and brings up custom silicon across multiple process nodes, working closely with world-class foundry and OSAT partners to deliver differentiated chips from concept to production. Efficient Computer is looking for a Test Engineer with hands-on DFT and fabless semiconductor test experience to join our Operations team. This is a mid-level role sitting at the intersection of Hardware Engineering and Supply Chain and Operations.
The right candidate has worked across the full test lifecycle - from DFT strategy and ATPG pattern generation through ATE bringup, OSAT coordination, and production test - and is equally comfortable working with external suppliers as they are with internal hardware engineers. You will serve as the primary interface between our engineering team and our foundry, OSAT, and test partners, owning test engineering across our active chip programs and scaling that foundation to future products.
What You Will Do
DFT Strategy and Pattern Development
  • 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
ATE Bringup and Test Program Development
  • 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
OSAT and Supplier Coordination
  • 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
Cross-Program Ownership
  • 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
What You Bring
Required
  • 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
