Job summary

Lightmatter is seeking a Design for Test Engineer to join our chip design and product operations teams. You will design, validate, and deploy DFT solutions for digital, analog, and photonic logic, collaborating across RTL, physical design, and QA to bring products to market.

You will work on ATPG, MBIST, and boundary scan, develop scalable automation, and support silicon bring-up in a fast-paced, innovative environment. A strong ASIC pre-silicon background is essential.

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field.
• At least 5 years of experience on DFT-related activities for advanced ASIC designs.
• Experience with pre-silicon design activities.
• 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.

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.
