DFT Implementation Lead

Job Description

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-à-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. 

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
