Lead High-Speed Electro-Optical Test Engineer

Job Summary:

We are seeking an experienced and highly skilled Test Engineer with advanced expertise in high-speed electro-optical components.

This individual uses hands-on proficiency with 100+ GHz real-time and sampling oscilloscopes, VNAs, and 1 mm GSSG probes to resolve a wide range of issues and develops new methods to solve problems in testing and optimizing high-speed optical and electrical components, aiming to achieve 400Gbps per optical lane transmissions for data center applications.

The ideal candidate will have direct experience with broadband AWGs, electro-optic modulator drivers, and evaluation of Mach-Zehnder Modulators (MZMs) or Electro-Absorption Modulators (EAMs), along with a comprehensive understanding of photonic integration platforms such as TFLN, InP, or SiPh.

This professional will lead projects independently with minimal guidance and is proactive in determining methods and procedures.

This role requires in-person work in the office.

This role supports the scaling of artificial intelligence (AI)/ machine learning (ML) infrastructure by enabling high-bandwidth, energy-efficient optical links-critical for low-power interconnects in inference and training datacenters, and essential as model sizes grow and data parallelism drives the need for scalable next-generation AI performance.

Primary Duties & Responsibilities


* Independently designs and executes experiments and performs high-frequency (≥100 GHz) testing of optical and electrical components in an electro-optical lab environment


* Analyzes and interprets complex test results, resolves a broad range of issues, and optimizes PAM-4/6/8 transmission and receiver-side equalization (FFE/DFE/CTLE/MLSE) performance for high-speed fiber optic transceivers in innovative ways


* Works on R&D projects to advance high-speed optical communication technologies


* Develops and refines product development documentation, including design specifications, test protocols, and reports

Education & Experience


* Advanced degree (MSc or PhD) in Electrical Engineering, Optical Engineering, Physics, or a related field.


* 5 years and a Master's degree; or a PhD with 3 years experience preferred.


* Highly advantageous for candidates with strong problem-solving capabilities in high speed data communications electro-optical lab testing.

Eye & Jitter Analysis


* Experienced in PAM-4/6/8 eye mask testing, jitter decomposition >100Gbaud, stressed bathtub curves, and S-parameter/time-domain de-embedding.

Component-Level Knowledge


* Modulators: EAMs (chirp, bandwidth), MZMs in SiPh (compact), InP (high BW), TFLN (low Vπ, high linearity), and emerging materials (plasmonic/polymer).


* Drivers/TIAs: ≥100GHz drivers (flat gain, return loss), TIAs with 100GHz BW, low input Z, low NF, and high linearity with photodetectors.

Photonic Integration (Preferred)


* Familiar with InP, TFLN, and heterogeneous integration (laser/modulator/detector).
