Job Description

As a Senior member in WLAN systems team you will play a key role spanning from development and implementation hardware accurate reference model for wireless LAN PHY baseband processing in pre-Silicon phase to PHY-Firmware bring-up in post Si phase.

Your Role

Key responsibilities in your new role:



Your key responsibilities in Pre-Si design phase would be:



Design, analysis, development & maintenance of WLAN Physical layer reference model in C/C++, System C and Matlab Identify post-Si bring-up issues and articulate them into improvements in PHY layer design Use case definition and generation of reference vectors for pre-Si RTL verification of the PHY blocks and working with the PHY design team to complete design verification. Collaborating with RF and Analog design teams in creation of the specs of the RF and modelling it in the simulation environment. Working with various Cross functional teams like MAC systems, Firmware development, Hardware board design teams, RF design teams to define, document the interfaces to PHY layer and model them in reference design to enable verification



In Post- Silicon phase, your core responsibilities would involve

Functional validation of WLAN PHY and its interfaces on emulation platforms Hands on silicon bring-up and validation with characterization over PVT to meet KPI's in the datasheet in the test/productional environment. Debugging and solving cross layer customer issues - working across boundaries of WLAN PHY, MAC, RF and board - while staying focused on the underlying problem.



You role would also require you to

Identifying issues and proposing design and methodology improvements while driving compliance of existing design flow Mentoring and training other team members as necessary Creating collateral for internal and external use as necessary.






Qualifications and skills to help you succeed :


10+ Masters in Electrical/Electronics Engineering (Specializing in DSP/Communication systems) or 12+ years with Bachelors in Engineering in Electrical/Electronics. Solid knowledge of Communication Theory /Signal processing concept/Wireless Communication and ability to apply these concepts to analyze and solve system level issues. Knowledge of PHY layer blocks like Carrier detection, Timing and frequency synchronization, AGC, filters, demodulators, tracking loops, decoders and their practical implementations in a wireless/wireline modem Good understanding of RF impairments and system level understanding of RF architectures Hands on Post-silicon experience of bring-up of chips with familiarity of typical lab equipment like Spectrum analyzer, signal generators and general lab automation Hands on experience of programming in Matlab/C fixed point models is essential Good debugging skills in C, using gdb, analysing crashes using stack trace are essential Familiarity with IEEE 802.11/802.15/3GPP standards is desirable Knowledge of C++/Tcl/Python/System C and HLS tools would be plus Ability to work with large, global, cross functional team Good communication and presentation skills.
