DFT Engineer

Delos Data•Palo Alto, CA

2d•Hybrid

About The Position

We are a stealth-mode startup building foundational technology to address performance, scalability, and resiliency challenges in large-scale AI data center clusters. We are backed by top-tier VC firms and notable angel investors. The company is led by experienced builders and operators who have founded companies, taken them to scale, and exited successfully. We work with a strong sense of unity and shared responsibility, and we expect trust, integrity, and respect in how we collaborate and make decisions. We hold ourselves accountable to one another and to the quality of the work we deliver. Headquartered in Silicon Valley, we operate across a mix of remote and on-site locations in the U.S. and Canada. We aim to create an environment where people are treated fairly, supported in their growth, and are empowered to do meaningful work alongside others who take the craft seriously.

Requirements

5+ years of experience in digital design verification, with at least 2 in DFT verification specifically
Strong hands-on experience with UVM-based or similar verification methodologies
Proficiency in SystemVerilog
Experience in scripting (preferably Python) and automation
Experience with industry-standard EDA tools (e.g., Synopsys VCS, Siemens/Mentor Questa, Cadence Xcelium)
Experience with industry-standard EDA DFT tools (e.g., Synopsys TestMax + Yield Accelerator, Siemens Tessent)
Solid understanding of digital design fundamentals
Experience with verification of test sequences for high-speed PHY logic including PCIe and Ethernet (10G/40G/100G)
Strong analytical and problem-solving skills
Clear written and verbal communication skills for cross-functional collaboration
High attention to detail and ability to deliver reliable, high-quality verification outcomes
Ability to work independently and manage tasks to completion

Nice To Haves

Experience with change control systems, especially git
Knowledgeable about DFT topics such as scan/ATPG, JTAG, ijtag (ICL/PDL), boundary scan, MBIST, memory repair, and fuseboxes
Experience with gate-level simulation and tester pattern formats such as STIL

Responsibilities

Develop, implement, and maintain RTL verification environments using UVM or equivalent methodologies
Create and execute coverage-driven verification plans aligned with design specifications
Use EDA DFT tools (e.g., TestMax, Tessent) to create and run recommended pre-silicon test cases for MBIST and scan fabric inserted by those tools
Develop directed test cases for other (non-vendor-supplied) DFT logic to validate functionality and identify corner cases
Assist in verifying ATPG patterns, especially at SOC level, along with manufacturing reset sequences
Analyze simulation results, debug complex verification and design issues, and perform root-cause analysis in collaboration with DFT design engineers
Implement and track functional and code coverage, driving verification to closure
Develop reusable verification components and write SystemVerilog Assertions (SVA)
Participate in design and verification reviews, providing input on design testability, correctness, and optimization
Automate regression testing and enhance verification infrastructure using Python and scripting
Contribute to continuous improvement of verification processes, tools, and methodologies
Along with the DFT designers, help support post-silicon test bring-up debug
