Job description
We are looking for a hands-on photonics experimentalist and test systems engineer to design, build, and scale the systems used to measure, validate, and productionize our optical platform.
This is not a traditional "test execution" role.
You will own how optical systems are measured, from first prototypes through high-volume production. This includes defining measurement strategies, building custom test systems, developing automation and analysis frameworks, and closing the loop between design, fabrication, and system performance.
Key ResponsibilitiesBuild & Own Optical Test Systems
- Architect and develop custom electro-optical test platforms at wafer, die, and module levels
- Design and integrate instrumentation such as optical spectrum analyzers, tunable lasers, polarization control systems, and RF/electro-optical measurement setups
- Build scalable, production-ready test racks and infrastructure
Drive Measurement Strategy & Insight
- Define and validate key optical performance metrics (e.g., insertion loss, return loss, polarization-dependent loss, chromatic dispersion)
- Develop novel measurement techniques and calibration methods where needed
- Use DOE, statistical methods, and modeling to extract signal and guide design decisions
Bridge R&D to Manufacturing
- Own the transition from lab validation to high-volume production test
- Establish MSA, CpK, SPC, and yield monitoring frameworks
- Support transfer of test systems to contract manufacturers and production partners
Close the Loop with Design
- Collaborate with photonics, device, and systems engineers to identify performance limitations and failure modes
- Debug complex issues across optical, electrical, and mechanical domains
- Drive design improvements based on test data
Build Automation & Data Systems
- Develop scalable test automation frameworks using Python, LabVIEW, or similar tools
- Create data pipelines and analysis tools (e.g., JMP, MATLAB, Python)
- Enable rapid debugging, visualization, and data-driven decision-making
Requirements
-
Bachelor's or Master's degree in Optical Engineering, Electrical Engineering, Physics, or a related technical field
-
6+ years of experience in photonics test, optical systems, or experimental optics
-
Hands-on experience building and debugging optical measurement systems (not just running tests)
-
Familiarity with telecom, datacenter optics, or silicon photonics systems
-
Experience with wafer-, die-, or module-level characterization
-
Experience building test systems from scratch and scaling them into production
-
Ability to bridge design, test, and manufacturing workflows
-
Background working with transceivers, PICs, modulators, lasers, or optical switching systems
-
Strong understanding of optical measurement physics
-
Experience with DOE, SPC, GRR, and yield optimization
-
Optical instrumentation: OSA, tunable lasers, OTDR/OFDR, VNA, BERT, polarization systems
-
Automation: Python (), LabVIEW/TestStand
-
Data analysis: JMP, MATLAB, or similar tools
Qualification
- Direct product experience testing specific components like DWDM filters, Mux/Demux, circulators, couplers, switches, etc.
- Comfortable working in a high-velocity, evolving environment with a willingness to travel to support manufacturing partners and field deployment as required
- Intimate knowledge of all of the following optical metrics and their measurement techniques: IL, RL, WDL, PDL, CD, DGD, GDR, and MPI
