Job description

Join a Growing ASIC Team Developing Next-Generation Silicon - Cambridge

I'm currently working with an innovative technology company that designs and develops its own silicon in-house. Following the successful delivery of multiple production ASICs, the team is continuing to expand as they develop the next generation of high-performance devices.

This is an excellent opportunity to join a collaborative ASIC team involved throughout the complete silicon development lifecycle—from architecture and specification through design, verification, implementation, manufacturing test and production.

As a DFT Engineer, you'll play a key role in developing robust Design-for-Test solutions for future ASICs, helping ensure high-quality silicon is delivered into volume production while balancing test coverage, implementation complexity and time-to-market.

You'll be responsible for defining, implementing and verifying DFT methodologies across complex SoC and IP designs, working closely with Design, Verification, Physical Implementation and Product Engineering teams.

Responsibilities

• Define DFT strategies at chip, subsystem and IP level
• Implement structural and functional DFT methodologies across complex ASIC designs
• Insert and integrate scan, MBIST, EDT, SSN and IJTAG-based test infrastructure
• Verify DFT implementation and debug related issues throughout the design cycle
• Support implementation and sign-off, including timing constraints, timing closure, power analysis and formal equivalence checking
• Work closely with Physical Design and Verification teams to ensure successful integration
• Support ATPG generation, silicon bring-up and manufacturing test
• Mentor and support other engineers within the team

What they're looking for

• Experience working within modern ASIC or SoC development flows
• Strong experience with Siemens Tessent DFT tools
• Good understanding of complex DFT challenges, including clocking, reset architecture and IP integration
• Experience with:ATPG
• MBIST
• Scan architecture
• DFT verification and simulation debug
• UPF and low-power verification concepts
• Good Tcl scripting skills (Python is also beneficial)
• Collaborative approach with excellent troubleshooting and debugging skills
• Knowledge of advanced silicon technologies and manufacturing fault models
• Familiarity with IJTAG / IEEE 1687 and related test access standards
• Experience supporting vector translation and production bring-up on ATE platforms
• Previous experience mentoring or coaching other engineers

About You

You'll enjoy solving technically challenging problems, working across multiple engineering disciplines and taking ownership of high-quality DFT implementation from architecture through to production.

You're someone who enjoys collaborating with experienced engineers, sharing knowledge, and contributing to the successful delivery of complex silicon products.
