Senior Electro-Optical Validation Engineer

About Inpho

Inpho is a fast-growing scale-up, focused on developing cutting-edge optoelectronic solutions for next-generation communications, and photonic systems. Our multidisciplinary team is pushing the boundaries of innovation in integrated photonics and semiconductor packaging.

Inpho’s new class of electro-photonic chips is poised to revolutionize and disrupt the optical interconnect market. Utilizing this new class of chips enables existing optical interconnect systems to be built at much lower cost; new architectures to be deployed that provide significantly higher price/performance; and a whole new generation of higher speed interconnect to be built that to date have been impossible.

About the Role

We are seeking a Senior Electro-Optical Validation Engineer to lead characterization and validation of Inpho's next-generation InP-based electro-optical components and photonic chips. This role suits an autonomous problem solver and proactive doer who can own device-level test and characterization from the ground up.

Key Responsibilities

• Set up, execute, and analyze time-domain (PAM4 eye quality), frequency-domain (S-parameter), chirp, linewidth, RIN, and spectral measurements.
• Own EVT/DVT planning, execution, and technical sign-off, including test coverage and acceptance criteria for high-speed InP modulators, EMLs, photodetectors, and next-generation electro-optical components.
• Bring up TIA evaluation boards and characterize TIA–photodetector interaction.
• Configure electro-optical measurements for EAM, EML, and PD devices across pad configurations and geometries using Keysight, Anritsu, and similar equipment, including high-speed probing, calibration, temperature stages, and alignment tolerances.
• Build Python data visualization and analysis tools that make complex performance data easy to interpret, such as extracting C/L/R from S-parameters and moving between S-, Y-, and Z-parameter representations.
• Work closely with the design and test teams to refine characterization methods and troubleshoot device-level issues.
• Lead characterization methodology for repeatable, defensible results, including separating device performance from equipment artifacts and recognizing when idealized parameters break down in practice.
• Take ownership of high-speed test equipment, including configuration, calibration, troubleshooting, and vendor interactions.

Required Qualifications & Skills

• Bachelor’s, Master’s, or higher degree in Electrical Engineering, Engineering Physics, or a related field.
• 8+ years of hands-on experience in high-speed electrical, RF, or electro-optical engineering roles in optical networking or related fields, including IMDD and PAM4 testing.
• Hands-on lab experience validating and characterizing InP electro-optical components and transceivers/pluggables.
• Proven expertise setting up and debugging high-speed test equipment.
• Strong problem-solving and data analysis skills, with proficiency in Python (Pandas, Plotly, or similar), MATLAB, or similar tools.
• Familiarity with semiconductor device physics (lasers, modulators, detectors).
• Comfortable working independently and within a fast-paced team.
• High attention to detail and proven ability to mentor developing engineers.
• Strong leadership, cross-functional communication, and decision-making.
• A continuous learner who stays current with the field.

Why Join Inpho?

• Be part of a mission-driven startup shaping the future of photonics.
• Competitive salary, full health benefits and equity packages, flexible work environment, and career growth opportunities.

Come work with a dynamic, high-talent team to design and commercialize the highest performance opto-electronic chips in the world!
