Job Summary
What Youll Do
We are seeking a highly skilled and motivated Senior Optical System Test Engineer to join our hardware engineering this role you will be responsible for the design development and execution of test and validation plans for advanced optical sub-systems including PICs linear drivers linear TIAs and DSPs supporting next-generation high-speed optical transceivers and photonic systems. This role is critical in bridging the gap between R&D and productization ensuring that our optical components and sub-systems meet the highest standards of performance reliability and manufacturability.
Key Responsibilities:
Develop and execute test plans for validating the performance and functionality of:
Photonic Integrated Circuits (PICs)
High-speed optical drivers
Transimpedance Amplifiers (TIAs)
DSPs
- Characterize optical and electrical performance metrics such as insertion loss extinction ratio jitter gain bandwidth and SNR.
- Set up and automate optical/electrical test stations using high-speed instrumentation and scripting tools (Python LabVIEW MATLAB etc.).
- Work with cross-functional teams (photonic design analog/RF design packaging firmware) to define test requirements and optimize test coverage.
- Conduct stress reliability and environmental testing (temperature cycling aging vibration) for optical components and assemblies.
- Perform high-speed eye diagram analysis TDECQ RIN and receiver sensitivity testing.
- Develop automation frameworks for regression testing and continuous validation in both lab and production environments.
- Analyze test results and generate detailed reports to support design reviews and product qualification.
- Support failure analysis and root cause investigations during design validation and product ramp-up phases.
- Collaborate with manufacturing teams to transfer test procedures and support volume production test development.
Qualifications :
- Bachelors degree in Optical Engineering Electrical Engineering Physics or a closely related field.
- Minimum of 3 years of hands-on experience in optical system or component-level testing.
Direct experience in testing and characterizing:
PICs (e.g. SOI InP or SiN platforms)
Optical driver ICs
Transimpedance Amplifiers (TIAs)
Strong familiarity with optical communication principles including NRZ/PAM4 modulation dispersion OSNR and jitter.
Proficiency with lab instrumentation including:
Optical Spectrum Analyzer (OSA)
BERT DCA high-speed oscilloscopes
Tunable lasers power meters VOA
Network analyzers and probes for high-speed electrical testing
- Experience with scripting and test automation using Python MATLAB LabVIEW or similar.
- Understanding of industry standards such as IEEE 802.3 QSFP-DD OSFP and CMIS.
- Strong analytical skills and ability to work independently to troubleshoot and resolve technical issues.
- Excellent documentation and communication skills.
Preferred Qualifications:
- Masters or Ph.D. in Optical or Electrical Engineering.
Experience with:
Silicon photonics-based PICs
Coherent optical systems
DSP-based transceivers
High-speed transceiver testing at 100G 400G 800G or 1.6T
- Knowledge of DSP tuning (FIR filters DFE CTLE) and eye diagram optimization.
- Familiarity with simulation tools such as ADS HFSS Lumerical or COMSOL.
- Experience in component-level reliability testing and qualification protocols.
- Exposure to high-volume production test environments and test data analytics platforms.
