Director of Silicon Test Engineering

The role

You will lead the strategy and execution of test development for silicon photonics and semiconductor products. You will build scalable test solutions from characterization through high-volume production.

What you will do

• Define and drive the end-to-end silicon test strategy from characterization to wafer sort and final test
• Lead development of ATE test solutions on platforms such as Advantest 93K and/or Teradyne
• Establish scalable test architectures to support rapid product ramps and high-volume manufacturing
• Own test coverage, quality metrics, and outgoing product reliability
• Optimize test flows to reduce test time, improve coverage, and lower cost of test
• Partner with product and process engineering to analyze yield data and drive continuous improvement
• Identify and eliminate test escapes
• Collaborate with design and DFT teams to ensure testability and coverage are built into products early
• Oversee development of high-speed test hardware and interfaces for advanced silicon photonics devices
• Build and lead a high-performing silicon test engineering team

Required qualifications

• 10+ years of experience in semiconductor or silicon photonics test engineering
• 5+ years of leadership experience managing engineering teams or complex test programs
• Deep expertise in ATE test development (Advantest 93K and/or Teradyne platforms)
• Strong background in silicon validation, production test, DFT/DFM, and high-speed digital or mixed-signal testing
• Experience optimizing test time, coverage, yield, and cost in high-volume manufacturing
• Proficiency in programming/scripting (C/C++, Python, Perl) and Linux environments
• Proven ability to collaborate cross-functionally and drive alignment across design, product, and operations
• Strong analytical, problem-solving, and communication skills
• Comfortable operating in a fast-paced, startup environment

Benefits

• Competitive salary commensurate with experience
• Comprehensive benefits package including health insurance
• Professional development opportunities and certification support
• Access to cutting-edge photonics technology and advanced packaging environments
• Collaborative work environment with cross-functional teams solving complex engineering challenges
