Job Description
You will be working on the design development and integration of calibration software modules for wireless communication systems using multiple antennas.
Design development integration and testing calibration software modules for a nextgeneration fixed wireless broadband system. The primary focus is functionality in layer 1 of the proprietary 5G protocol such as channel estimation IQ imbalance correction and LO leakage cancellation.
You will develop software running on both the base station and user equipment of a broadband wireless access system for various multicore DSP/ARM processors and realtime operating systems. You will collaborate closely with L2/L3 software groups and FPGA/ASIC teams to deliver crosslayer features.
Job Responsibilities:
- Design and develop scalable PHY/Calibration software modules on multicore DSP/GPP using C/C
- Define and develop unit test vectors using Matlab and C for the software modules and unit test extensively to deliver flawless modules
- Test and validate the performance of the software modules on the real system.
- Develop scripts to qualify the RF board testing
Required Skills & Experience:
- MS or PhD in Electrical Engineering/Computer Science with an emphasis in wireless communication and/or digital signal processing
- 512 years of industry experience in DSP software development for wireless communication systems (such as 5G LTE WiFi or similar proprietary protocols)
- Formal understanding in communication and signal processing theory and techniques with strong mathematical background in linear algebra
- Experience in developing and implementing wireless communications systems in at least one of the following areas:
- Array signal processing such as beamforming and MIMO techniques for an OFDM system
- Physical/MAC/baseband layer software implementation for LTE/5G.
- Adaptive equalization receiver synchronization signal identification and recovery
- Experience with OFDM based system implementation
- Experience with version control systems collaboration tools (wikis ticket systems)
- Experience in scripting languages (python bash etc)
Knowledge and Skills:
- Formal understanding of communication and signal processing theory and techniques including OFDM communication systems and a strong mathematical background in linear algebra
- Strong background in C C and Python programming
- Experience with software development for multicore embedded systems including realtime operating systems (RTOS) memory and cycle optimization caches multithreaded programming interprocess communication and HW/SW interaction
- Comprehensive knowledge of one or algorithms used in wireless communications systems and associated design and implementation in software. Relevant experience could be in areas such as:
- RFIC impairments and compensations SW development and validation
- Calibration procedures for multiantenna based systems
- Advanced array signal processing techniques such as beamforming and MIMO
- Adaptive equalization receiver synchronization signal identification and recovery
Experience with version control systems (Git Gerrit Gitlab) and issue tracking and collaboration systems (Jira Confluence)
Since our founding in 2009 weve been on a mission to accelerate the pace of bringing fast and affordable internet access and all the benefits it provides to the 90 of the worlds households who cant get it. Through a decade of R&D and more than $400M of investment weve created an entirely unique nextgeneration fixed wireless access technology powering our first commercial platform Gigabit 1 (G1. It delivers a gamechanging advance in broadband economics in both mainstream and underserved markets using either licensed or unlicensed spectrum. G1 started production in mid 2021 and has now been installed by over 160 service providers globally. Were headquartered in Milpitas California with additional research and development in Pune India.
G1 has been developed by an incredibly talented and pioneering core technical team. We are looking for more worldclass problem solvers who can carry on our tradition of customer obsession and groundbreaking innovation. Were well funded growing incredibly quickly maintaining a superb resultsfocused culture while were at it and all grooving on the positive difference we are making for people all over the planet.
