Senior DFT Engineer

Job Title

Senior DFT Engineer

Role Summary

Join the Edinburgh digital design team to define and implement DFT architectures across complex ASICs to maximize manufacturing test coverage, support silicon bring-up, and improve product reliability.

The role works closely with RTL, verification, physical design, and test engineering teams and contributes to automation and methodology improvements.

Experience Level

Senior — typically 7+ years of relevant DFT / ASIC experience or demonstrable equivalent industry experience.

Responsibilities

Primary responsibilities include:

• Define and implement chip- and block-level DFT strategies for complex ASICs.
• Develop and integrate scan architecture, scan compression, boundary scan, MBIST and LBIST solutions.
• Drive ATPG generation, fault simulation, failure diagnosis, and coverage closure.
• Collaborate with RTL, verification, synthesis/STA, physical design, and test teams to integrate DFT constraints and flows.
• Perform DFT verification using simulation and support silicon bring-up, debug, and failure diagnosis.
• Develop automation scripts and methodologies to improve DFT productivity and quality.

Requirements

Must-have skills and experience:

• Proven industry experience in a DFT engineering role.
• Strong understanding of digital design and test methodologies.
• Hands-on experience with scan insertion and scan compression techniques.
• Experience with ATPG tools and fault simulation, and with test coverage analysis and diagnosis.
• MBIST and LBIST implementation experience.
• Familiarity with JTAG / IEEE 1149.1 standards.
• Experience with industry EDA tools such as Siemens Tessent and Synopsys TetraMAX/TestMAX.
• Strong scripting skills in Tcl and Python.
• Familiarity with Verilog/SystemVerilog and simulation environments.
• Excellent debugging, problem-solving, communication, and collaboration skills.

Education Requirements

Bachelor's, Master’s or PhD degree in Electrical Engineering or a related discipline; proven industry experience in a DFT position is required.
