About the role
Director level leadership role focused on strategy and execution of silicon photonics test development from characterization through high-volume production, partnering with design, product, and operations to ensure robust test coverage, optimized test cost, and high-yield manufacturing.
Responsibilities
- 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, ensuring robust screening of marginal or underperforming devices
- Implement data-driven methodologies for yield learning and production ramp
- Collaborate with design and DFT teams to ensure testability and coverage are built into products early
- Translate simulation test patterns into ATE programs and production-ready solutions
- Lead test plan reviews and drive alignment across engineering, product, and operations teams
- Support new product introduction (NPI) and ensure seamless transition to high-volume manufacturing
- Oversee development of high-speed test hardware and interfaces for advanced silicon photonics devices
- Ensure test solutions meet performance requirements for high-speed and mixed-signal applications
- Drive innovation in test methodologies as product complexity exceeds standard tester capabilities
- Build and lead a high-performing silicon test engineering team
- Set clear goals, drive accountability, and foster a culture of execution and continuous improvement
- Mentor and develop engineers across test, product, and operations functions
- Lead through influence across internal teams and external partners
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
