The Principal Test Engineer - Security and Provisioning

Job Title

The Principal Test Engineer — Security and Provisioning

Role Summary

Responsible for defining, developing, validating, and deploying secure provisioning flows on ATE for semiconductor manufacturing. Own the manufacturing execution of security lifecycle transitions, eFuse/OTP programming, fuse readback and validation, secure debug control, device identity provisioning, and production guardrails across wafer sort, final test, SLT, and high-volume manufacturing.

Collaborate with Design, DV, Security Architecture, Firmware, Product Engineering, and Manufacturing to ensure secure, manufacturable provisioning and release processes. No relocation package provided.

Experience Level

Senior / Principal — requires 10+ years of experience in semiconductor manufacturing, test development, product engineering, production test, or silicon bring-up.

Responsibilities

Main responsibilities include defining and executing secure provisioning strategies on ATE and ensuring robust production controls.

• Own end-to-end ATE provisioning strategy: lifecycle state transitions, secure boot enablement, device identity, debug lock/unlock policy, and production fuse programming.
• Design manufacturing-friendly fuse and provisioning flows: write/readback/verify, margin reads, error handling, retry limits, binning, audit logging, and clear pass/fail criteria.
• Develop and validate Advantest 93K test methods, SmarTest patterns, digital patterns, datalogging, and production flows for provisioning and post-provisioning integrity checks.
• Partner with DV and design teams to validate provisioning sequences, security blobs, fuse programming models, lifecycle transitions, and negative/error scenarios before silicon execution.
• Define production controls and documentation to prevent over-fusing, incorrect lifecycle transitions, partial or duplicate programming, wrong-blob usage, and unauthorized debug enablement.
• Support wafer sort, final test, SLT, and HVM release activities and cross-functional debug across silicon, ATE, firmware, security, and design teams.

Requirements

Must-have technical skills and experience for successful performance in this role.

• 10+ years in semiconductor manufacturing, ATE test development, product engineering, production test, or silicon bring-up for complex SoCs or advanced devices.
• Hands-on experience with Advantest 93K and SmarTest 7/8: test development, digital patterns, STIL/pattern generation, test methods, datalogging, and production integration.
• Experience with eFuse/OTP/non-volatile fuse programming, fuse controllers, lifecycle controllers, JTAG indirect access, readback/verify flows, and margin validation.
• Familiarity with security provisioning flows: secure debug states, device provisioning, key/certificate/blob handling, secure boot enablement, DICE/attestation/Root-of-Trust or equivalents.
• Ability to read fuse maps, security registers, and access paths (JTAG/DAP/APB/AXI) and to define manufacturing access restrictions and traceability.
• Proven cross-functional execution and communication with Design, DV, Security Architecture, Firmware, Product Engineering, and Manufacturing teams.
• Strong understanding of wafer sort, final test, SLT, HVM release processes, production quality controls, and data integrity.
• Nice-to-have: experience with RSE, Caliptra, provisioning appliances, or similar secure manufacturing infrastructures.

Education Requirements
