About The Position

As Director of Silicon Test Engineering, you will lead the strategy and execution of test development for Lumilens’ silicon photonics and semiconductor products. You will be responsible for building scalable, high-quality test solutions from characterization through high-volume production.
This role partners closely with design, product, and operations teams to ensure robust test coverage, optimized test cost, and high-yield manufacturing. You will play a critical role in ensuring only fully validated, high-performing devices reach our customers.

Requirements

• 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

Responsibilities

• Lead Test Strategy & Execution
• 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
• Drive Yield & Test Optimization
• 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
• Partner with Design & Cross-Functional Teams
• 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
• Develop Test Infrastructure & Hardware
• 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
• Leadership
• 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

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
