Job description

Join the leading chiplet startup! As an Eliyan DFT Implementation lead, you will be working at a fast-paced early-stage startup creating technologies that fuel tomorrow’s chiplet based systems with best-in-class power, area, manufacturability, and design flexibility. You will be responsible for crafting DFT implementation schemes for best-in-class PHYs and Controllers. You will work with a cross-functional team of experts that operate from first principles, innovate and push the envelope to create high-volume and high-performance manufacturable products. We offer a fun work environment with excellent benefits. ONSITE M-F
Key Responsibilities

• Develop and implement innovative DFT IP and features to support ATE, in-system test, debug, and diagnostics.
• Contribute to flow and methodology development working closely with the digital, analog and physical design teams.
• Collaborate with cross-functional teams to integrate DFT features into the RTL design and ensure seamless validation and verification.
• Work closely with the STA methodology owner in defining hierarchical DFT constraints and multi-mode multi-corner sign-off.
• Produce area/power tradeoff against design choices made for improved DFT coverage.
• Own complete architecture, tool/vendor selection for DFT insertion, simulation, fault debug and characterization.
• Work closely with design, design-verification, and physical design teams to enable the integration and validation of test logic.
• Participate in the development of innovative hardware DFT and physical design aspects for new silicon device models.
• Create and maintain dashboards for tracking DFT collaterals to be handed over to Test Engineering, including coverage matrix.
• Responsible to produce a DFT architecture document for every PHY / chiplet programs specifying a detailed list of collaterals for customers.
• Work closely with physical implementation teams to define the optimal MMMC corners for various stages of implementation vis‑to‑vis placement, CTS and routing for DFT modes.
• Own the DFT architecture for 2.5D/3DIC multi-die products – hierarchical test access across base and stacked dies, die‑to‑die interconnect test, and IEEE 1838 / 1687 (IJTAG) based test infrastructure.
• Define Known‑Good‑Die (KGD) test and screening strategies for chiplets and hard IP, spanning pre‑bond (wafer sort/probe), mid‑bond and post‑bond test content, and the stress/burn‑in screens needed to hit KGD quality and DPPM targets.
• Architect DFT for die‑to‑die interfaces (Eliyan NuLink / BoW / UCIe‑class PHYs), including at speed interconnect test, PHY loopback modes, lane repair and redundancy, and margining hooks for in‑system diagnostics and yield recovery.
• Deliver chiplet‑and IP‑level DFT collateral that customers can drop into their own 3DIC test architectures – IEEE 1500‑style test wrappers, retargetable pattern sets, and plug‑and‑play integration documentation.

Qualifications

• Bachelor's or Master's degree in Electrical or Computer Engineering.
• At least 15 years of experience in hardware DFT, testability, and physical design.
• Proven expertise in JTAG protocols, scan and BIST architectures, memory BIST, and boundary scan.
• Experience with ATPG and EDA tools (Tessent, TetraMax, Genus, Tempus, DC, PrimeTime)
• Experience with gate-level simulation, running SDF annotated simulations for test vector set
• Experience with post‑silicon validation and debug, ATE patterns bring‑up on Advantest ATEs.
• Hands‑on DFT experience on 2.5D/3DIC and chiplet‑based systems: multi‑die test access architectures, pre‑bond / mid‑bond / post‑bond test, TSV, micro‑bump and hybrid‑bond interconnect test, and die‑to‑die (UCIe / BoW class) interface test and loopback.
• Working knowledge of IEEE 1838 (3D test access), IEEE 1687 (IJTAG), and IEEE 1500 core test wrappers for hierarchical, pattern‑retargetable IP and chiplet test.
• Demonstrated experience defining Known‑Good‑Die (KGD) screening and quality flows – wafer‑level test content, DPPM/yield target setting, and stress or burn‑in screening for die destined for advanced packaging.
• Experience delivering DFT collateral for licensable IP or chiplets to external customers, including test wrappers, retargetable patterns, coverage reports, and integration/hand‑off documentation.
• Scripting skills in Tcl, Python, or Perl.
• Proven track record of being a highly visible contributor as part of a start‑up like environment.
• Problem solver and efficient in written/verbal communication – excellent data organization skills and churns high‑quality work product.
• Ability to work cross‑functionally with digital, analog design, and implementation teams.
