Wireless PHY System Bringup Engineer

Wireless PHY System Bringup Engineer

Requirements

• BS and 3+ years of relevant experience.

Responsibilities

• Transmit and receive chain bringup, tuning, and debug; optimizing PHY and calibration algorithms such as TPC, AGC, TSSI, RSSI, interference mitigation and others.
• Collaborate closely with other PHY systems and algorithm engineers as well as MAC, Radio, and digital circuit designers.
• Develop chip control drivers and reference implementations in the bringup environment and work closely with firmware engineers to integrate these algorithms into the firmware.
• Guide and assist the characterization team in identifying and resolving reported issues.

Preferred Qualifications

• Experience, knowledge and skills on wireless system design, integration, bring up, characterization and debug of wireless communication systems, ideally on an SOC.
• Proficiency in wireless transceivers, RF front-end architectures and performance tradeoffs.
• Proficiency in system-level parametrics, such as EVM and Sensitivity, and impairment mitigation.
• Understanding of communication theory and signal processing related algorithms (such as timing recovery, signal estimation and detection, automatic gain control, RF impairment estimation and correction, channel estimation, equalization).
• Proficiency using and understanding of the theory of operation of lab equipment (spectrum analyzer, signal generator, power meter).
• Experience with at least one of Matlab, Python, Shell scripting and/or C/C++ is required.
• Experience with automation infrastructure development (traceability, repeatability) and related tools (GIT, CI, database, reporting tools).
• Knowledge in existing wireless communication protocols: 802.11a/b/g/n/ac/ax/be, LTE/WCDMA/GSM, or 802.11ad/ay.
• Preferred advanced degrees MS or Ph.D in Electrical Engineer or Computer Engineering.
