Senior Test Engineer, Photonics Systems
Thrively is partnering with an innovative, well-funded hardware startup at the intersection of MEMS, silicon photonics, and AI-scale infrastructure. The role involves owning system-level silicon photonics testing and characterization, defining test methodologies, developing automation, and ensuring high performance and reliability through hands-on testing.
Responsibilities
Build end-to-end test readiness for the company’s optical product line, ensuring coverage for all critical performance and reliability metrics
Conduct Measurement System Capability and Process Capability Analysis (MSA/CpK)
Ensure test processes comply with relevant industry standards (e.g., Telcordia, JEDEC)
Design and implement test equipment and fixtures—both internally developed and through external partners
Evaluate and select optical test instruments to ensure required precision and measurement capability
Develop and maintain high-quality Python-based test and process automation
Integrate and debug test hardware/software, defining test cases, parameters, and acceptance criteria
Own troubleshooting and validation of complex electromechanical and optical test stations
Apply Gage R&R, DOE, JMP, MATLAB, and statistical tools to separate signal from noise
Lead structured root-cause investigations (FMEA, 8D, 5-Whys)
Monitor test yield and drive test-process optimization
Collaborate effectively with multidisciplinary engineering teams and contract manufacturers
Produce thorough documentation: test diagrams, engineering drawings, specifications, SOPs, and work instructions
Maintain organized, accessible, and traceable test data
Qualification
Required
Bachelor's or Master's degree in Optical Engineering, Electrical Engineering, Physics, or a related technical field
6+ years of experience in systems engineering or test development within hardware, high-volume manufacturing, or startup environments
4+ years hands-on experience in optical and systems testing focused on singlemode optics and passive components for telecom/datacenter applications
