What You Can Expect
-
Own the end-to-end architecture and performance of the electro-optical transmit path: from the electrical driver interface, through the PIC and package, to the optical output (at 400G/lane CPO and beyond)
-
Define and partition system-level specifications and budgets across the digital, analog, electro-optical domains; translate link targets (BER, SNR/OSNR, OMA, TDECQ) into component-level requirements
-
Model and predict end-to-end optical link performance via eye diagrams, constellation diagrams, and impairment analysis, and quantify how equalization and DSP (FFE, DFE, CTLE, and coherent DSP functions) shape achievable performance
-
Support co-design and technical alignment across photonics, analog/ASIC design, and packaging teams to optimize performance, power efficiency, and signal integrity.
-
Plan, execute, and lead characterization and qualification of electro-optical components and integrated systems; define test methodologies and acceptance criteria
-
Analyze measurement data to identify performance limitations; lead root-cause analysis of complex signal integrity issues across electrical and optical domains, and translate findings into design improvements
-
Represent system-level requirements in architecture and interface definition; ensure designs align with industry standards (IEEE 802.3, OIF CEI) and customer specifications
What We're Looking For
-
Master’s degree or PhD in Electrical Engineering, Photonics, or a related field, with 3+ years of industry experience in a high-tech engineering environment
-
Strong background in optical communications (coherent and/or IM/DD) or high-frequency electrical/electro-optical characterization (>110 GHz). Demonstrated experience with link-level performance analysis via eye diagrams, constellation diagrams, BER, SNR/OSNR, OMA, and TDECQ
-
Hands-on experience in electro-optical device testing (e.g., modulators, photodetectors, lasers); high-speed testing (>110 GHz) preferred
-
Solid understanding of RF/microwave engineering, signal integrity, high-frequency circuit theory, interconnects, silicon photonics, and semiconductor packaging
-
Strong ownership mindset with the ability to operate autonomously in a fast-paced environment
-
Collaborative approach with the ability to influence cross-functional teams and drive technical alignment
-
Excellent communication skills, with the ability to explain complex topics clearly to diverse audiences
-
Proven track record of delivering high-quality results in ambiguous or evolving environments
In-depth experience in two or more of the following:
-
High-speed link modeling, channel budgets, and equalization techniques (FFE, DFE, CTLE)
Interfacing with high-speed SerDes (- 200G PAM4, ideally 400G PAM4) and familiarity with industry standards (IEEE 802.3, OIF CEI)
-
High-frequency characterization and data modulation (VNA, AWG, PPG, oscilloscope, DCA, BERT)
-
Python or MATLAB for lab automation, data analysis, or system simulation
-
3D EM modeling and simulation (HFSS preferred), high-frequency circuit simulation (ADS preferred), and/or RF PCB design
-
Advanced packaging and/or 2.5D/3D integration in optical platforms
