GNSS Measurement Engine Firmware Engineer

Summary

Global Navigation Satellite Systems (GNSS) space vehicles transmit the power of a lightbulb, they are 13,000 miles away, and are moving four kilometers per second. The received signals are commonly one hundred times weaker than cosmic microwave background radiation left over from the Big Bang and arrive next to interfering signals ten billion times stronger, just few MHz away. Our GNSS team is part of Apple's Cellular SoC team. We are a vertically coordinated engineering team spanning RF, mixed-signal analog design, systems engineering, RTL design, design verification, firmware and software engineering, test, and validation. Our focus is on highly energy efficient and robust GNSS receiver design. We develop GNSS technology that touches hundreds of millions of lives, something we are passionate about.

Description

As a GNSS Measurement Engine Firmware Engineer, you will be a key member of our highly innovative GNSS design team. You will be defining firmware architecture, documenting the firmware design, developing, testing and integrating infrastructure software and digital signal processing software for novel ultra-low-power GNSS system.

Minimum Qualifications

BS and 10+ years of relevant experience 10 years of embedded software development experience using C, C++, as well as scripts languages such as MATLAB and Python. 5 years of product development experience in wireless communication, GNSS, or other relevant industry.

Preferred Qualifications

MS in CS, EE, Geomatics is preferred Familiar with microprocessor such as ARM, RTOS, driver development for PHY hardware and peripherals such as SPI, UART, Ethernet. Experience in performing low-level drivers and HW bring-up, using test tools and interacting with HW and SoC design teams, implementing diagnostics, manufacturing tests, and protocol compliance test software. Practical experience of digital signal processing algorithm implementation in an embedded system. Experience in developing GNSS measurement engine (ME): acquisition, tracking, impairment, AGNSS, coexistence, multipath and jamming mitigation or other wireless location technology is a huge plus. Experience in embedded software architecture and optimization is a plus.
