Principal Engineer, DFT

About this role

About the Role We’re looking for a highly experienced DFT Lead to own Design for Test (DFT) for Kepler’s memory products. You’ll architect, implement and drive to tapeout a complete DFT solution. You’ll make well-reasoned trade-offs across test coverage, test time, area overhead and power throughout. Responsibilities Own DFT architecture and implementation end to end, from definition through RTL, netlist, verification and tapeout.

Drive the design of programmable memory BIST engines, including test algorithms, address sequencing, repair flow and fail analysis tailored to the memory architecture.

Design repair and redundancy management (hard and soft repair, repair data storage) and fail logging and diagnostics infrastructure.

Define DFT strategy: full-scan ATPG, embedded compression, MBIST, JTAG, boundary scan and hierarchical test integration.

Drive test coverage closure: fault models, coverage targets and ATPG pattern optimization.

Work with architecture, RTL, physical design, packaging and post-silicon validation teams to build DFT-aware decisions early.

Set DFT best practices, sign-off infrastructure and documentation standards.

Requirements B.Tech/M.Tech/MS in EE, ECE, Computer Engineering or a related field.

15+ years of hands-on DFT architecture and implementation experience on complex ASIC/SoC designs, with multiple silicon tapeouts.

Deep ATPG expertise (stuck-at, transition, path delay, cell-aware) using industry-standard DFT tools.

Strong MBIST architecture and implementation experience on large designs.

Hands-on experience designing or modifying programmable BIST engines for memory testing, including repair flow and diagnostics.

Strong knowledge of JTAG TAP controller design and boundary scan (BSR, BSDL, compliance).

Solid understanding of hierarchical DFT architecture, scan chain partitioning and scan compression.

Understanding of DFT-aware RTL practices and how DFT interacts with physical design.

Experience with ATE interfaces and production test program development.

Strong scripting skills (Python, Tcl, Perl).

Excellent communication skills with a proven ability to own complex DFT solutions end to end in a fast-paced environment.

Nice to Have Experience with memory test, repair and yield learning in high-volume manufacturing.

Knowledge of DFT and test strategies for 3D innovations.

Prior startup experience with lean teams and aggressive schedules.
