Role Summary

Plans, designs, develops and tests software systems or applications for software enhancements and new products including cloud-based or internet-related tools.
May use common development methodologies such as Waterfall and Agile.

Key Responsibilities

· In Lead Developer / Architect role, create SW architecture specifications and translate L1 feature requirement set to L1 component SW architectures and high level designs

· Lead product algorithm and system architecture design & improvement:

o Analyze the current product algorithms to find areas for improvements.

o Develop algorithms with high performance but with small computational complexity.

o Conduct analytical and numerical analysis in link/system level, with leveraging fundamental knowledge on wireless

o Develop link/system level simulators tailored to individual features to improve

o Lead developing L1 modem algorithms, L2 algorithms and MU-MIMO related algorithms, etc.

· Lead product validation, tests, and field trials:

o Define system, lab and field test cases, and corresponding pass criteria for validating these features of interest

· Conduct root cause analysis for product defects with utilizing product log analyzer, QXDM, QCAT, X-CAP, etc.

Job Requirements

· Over 4-12 years of engineering experience and BE/BTech/ME/MTech from in EE/ECE/CSE (or equivalent) from recognized universities
