Résumé du poste

microTECH Global LTD is seeking an experienced IC design-minded researcher to contribute to system architecture, partition analog and digital implementations, and support IC design, verification, and characterization. You will work closely with AMS and Digital IC teams on modeling, simulation, and hardware testing to ensure accurate, energy-efficient implementations.

You will model optical and RF channels, develop DSP algorithms, and validate performance on hardware, bridging theory and

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.

Responsabilités

• 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.

Description du poste

You will work closely with the Analog and Mixed-Signal (AMS) and Digital IC design teams to contribute to system architecture, partition analog and digital implementations, model channels, and support IC design, verification, and characterization.

Your key responsibilities will include

• Channel Modeling: Model optoelectronic components (e.g., laser drivers, Transimpedanc eAmplifiers (TIA)), photonics (e.g., VCSEL, PIN photodiodes), and optical transmission effect s(e.g., chromatic dispersion (CD), effective modal bandwidth (EMB), modal noise (MN), an andmode partition noise (MPN)), understanding their impact on signal distortion, both linear an ndnon-linear, noise and jitter
• Algorithm Development: Invent, simulate, and validate energy-efficient DSP algorithms in both floating-point and fixed-point precision. These algorithms will be used for adaptive AM Sblocks calibration, adaptive channel equalization, timing recovery, symbol synchronization, FEC encoding/decoding, and signal quality assessment for both electrical and optical physica
• Hardware Testing & Optimization: Measure and optimize algorithms on actual hardware, correlating models and performance with prior simulations. You will refine models and update simulation environments to ensure alignment with experimental data
