Qualifications

• At least 10 years of industry experience in related field.
• Master's or Ph.D. in electrical engineering, physics, or mathematics is highly recommended, although not strictly required.
• Strong background in Information Theory, DSP, and FEC for optical and/or electrical communications.
• Experience in modeling communication systems, with a preference for expertise in optoelectronics and optical channel modeling.
• Proficiency in programming languages such as MATLAB, C/C++, or similar.
• Familiarity with Unix operating systems, particularly Linux, and version control systems, particularly SVN.
• Experience with collaboration with IC designers.
• Knowledge of intensity-modulation/direct-detect (IM/DD) optical communications.
• Ability to present and defend technical information to colleagues.

Responsibilities

• Channel Modeling: Model optoelectronic components (e.g., laser drivers, TIAs), photonics (e.g., VCSEL, PIN photodiodes), and optical transmission effects; assess their impact on signal distortion, both linear and nonlinear, noise and jitter.
• Algorithm Development: Invent, simulate, and validate energy-efficient DSP algorithms for adaptive AMS blocks calibration, adaptive channel equalization, timing recovery, symbol synchronization, FEC encoding/decoding, and signal quality assessment for electrical and optical physics.
• Hardware Testing & Optimization: Measure and optimize algorithms on actual hardware, correlating models and performance with prior simulations; refine models and update simulation environments to ensure alignment with experimental data.
