Senior DFT Engineer

Role : Senior DFT Engineer

Location : Remote Candidates should preferably be based in the PST time zone (California preferred).

Duration : Long term

The Role

We are seeking a highly experienced Senior Design-for-Test (DFT) Engineer to lead and drive DFT architecture and implementation for complex mixed-signal SOCs. This role requires deep expertise in memory BIST and TAP controller insertion at RTL, scan insertion and ATPG, and test strategy development across digital and mixed-signal domains. You will play a critical role in ensuring high test coverage, manufacturability, and first-pass silicon success while collaborating closely with design, verification, and physical design teams.

Responsibilities

• Define and implement DFT architecture for mixed-signal SoCs, including scan, MBIST, LBIST, and boundary scan.
• Lead RTL-level DFT insertion, scan chain insertion and optimization, test point insertion, and low-power DFT methodologies.
• Own ATPG flow development and execution by generating high-quality stuck-at, transition, and path delay test patterns. Drive coverage closure and pattern optimization and debug pattern failure and silicon correlation.
• Develop and integrate DFT strategies for mixed-signal blocks, including wrapper-based approaches, and analog test interfaces and BIST solutions.
• Collaborate with RTL, DV, and PD teams to ensure clean DFT integration at RTL and gate-level, and timing and physical constraints alignment (scan reordering, compression, etc.).
• Drive DFT verification and signoff, including Scan/ATPG coverage metrics, DRC/Lint checks (DFT rule compliance), gate-level simulation and pattern validation.
• Support bring-up and silicon debug activities by analyzing tester failures, yield issues, and ATPG pattern correlation with silicon behavior.
• Contribute to methodology development, automation, and flow improvements.

Qualifications

• S. or M.S. in Electrical Engineering or related field.
• 7+ years of experience in DFT for complex SoCs.
• Strong hands-on experience with RTL DFT insertion (scan, compression, test points), and ATPG tools and flows.
• Deep understanding of scan architectures, compression techniques, fault models (stuck-at, transition, bridging, path delay), coverage analysis and closure

strategies.

• Experience with low-power DFT techniques.
• Familiarity with mixed-signal integration challenges and test methodologies.
• Strong debugging skills across RTL, gate-level, and silicon.

Nice to Have

• Experience with MBIST/LBIST implementation and memory repair flows.
• Knowledge of IEEE 1149.x (JTAG/boundary scan) standards.
• Experience with multi-voltage domain and power-aware DFT.
• Exposure to physical design impacts on DFT (scan chain reordering, congestion, timing).
• Scripting experience for automation.
• Experience in high-speed interfaces (SerDes) or RF/mixed-signal SoCs.
• Prior involvement in A0 silicon bring-up and yield ramp.
• Experience working in cross-functional, geographically distributed teams.
