Sr. Design for Test (DFT) Engineer

Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world’s first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads. Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter! If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders. Lightmatter is (re)inventing the future of computing with light! As a Design for Test Engineer you will work closely with all disciplines involved in chip design and product operations to design, validate, and deploy test solutions for digital, analog, and photonic logic. You will be involved in a variety of tasks including logic design, validation and logic simulations, scripting, timing closure, post-silicon planning and bring up, and bringing products to market. Responsibilities • Create new chip, module, and system-level DFT solutions for our highly integrated photonics-based AI platform • Develop and deploy DFT methodologies for our next generation products • Provide architecture for integrated electronics/analog/digital test including ATPG and boundary scan • Work with RTL designers to define front-end integration • Work with physical-design engineers to provide backend integration • Create automated flow that can scale with the team and company • Support initial silicon bring-up through debug • Validate DFT implementation and requirements • Proactively solve problems while managing deliverables in a fast-paced, evolving environment. Minimum Qualifications: • Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field • At least 5 years of industry experience working on DFT-related activities for advanced ASIC designs • Proven experience in pre-silicon design activities • Work independently on daily tasks and projects, while seeking guidance for new and unfamiliar assignments. • Experience with scripting languages such as Python or TCL • Solid understanding of DFT concepts such as Scan, ATPG, memory test, and JTAG • Knowledge of Basic SoC Architecture and HDL languages like Verilog • Experience working with commercial EDA DFT tools on MBIST, ATPG, and Boundary Scan. Preferred Qualifications: • Master degree in Electrical Engineering, Computer Engineering, or related field with 3+ years of industry experience working on ASIC designs with multiple production-quality ASIC tapeouts • Prior experience working on DFT related tasks in either logic design, validation, implementation or pattern generation and coverage analysis • Understanding of industry standards and practices in DFT, including JTAG/BSCAN, at-speed Scan-ATPG, MBIST, and trade-offs between test quality and test time • Ability to conduct experiments during silicon debug, gathering and analyzing data, and utilize scripting to support efficient handling of ATE data • Understanding of Timing, Physical Design, and Power impact of DFT structures • Strong teamwork and communication skills with the ability to collaborate with multiple functional teams across a variety of fields We offer competitive compensation.
