Senior Staff Real-Time Embedded SW Engineer

Company Summary:

oneNav is powering high-performance positioning for location-dependent mobile services. Based in Silicon Valley, oneNav is developing a next-generation, pureL5 mobile GNSS receiver for smartphones, wearables, and IoT devices.

Job Summary:

This position is focused on contributing to the team responsible for delivering the world’s first commercial real-time embedded measurement engine (ME) for a pureL5 GNSS receiver. The oneNav ME Firmware (FW) leverages oneNav’s breakthrough L5 array processor embodied in an FPGA and on track for implementation in silicon. ME tasks include (re)acquisition and tracking of BeiDou, Galileo, and GPS signals and decoding navigation data messages for the position, velocity, and time estimate that are fed to the Positioning Engine (PE). The PE features classic PE approaches together with groundbreaking Machine Learning (ML) methods that dramatically improve horizontal accuracy even in the most challenging environments.

Expected Salary: $50,000 – $100,000 /yr


  • Contribute to the delivery of timely, commercial, portable, real-time embedded C ME FW in support of the oneNav pureL5 GNSS Receiver IP core product.
  • Work closely with world-class GNSS technical experts to implement ME features unique to a pureL5 receiver including multi-constellation acquisition, tracking, and reacquisition, secondary code estimation, interference detection and mitigation, multipath and correlation analysis.
  • Generate code consistent with FW development practices aligned with DevOps principles and implemented in a CI/CD workflow.

Skills and Experience:

  • 5+ years proven track record of embedded FW development featuring new hardware development and prototyping environments (e.g., Xilinx Zynq or Zynq Ultrascale+ FPGA, test chips)
  • 5+ years of hands-on real-time embedded FW development with RTOS on ARM or RISC-V, including familiarity with JTAG, Boot Loaders, and Data Capture Tools
  • Track record of delivery of high quality timely commercial products for mobile wireless, IoT, and GNSS
  • Expert in C/C++, performance profiling, memory optimization, and assemblers
  • Experience with driver-level configuration and management, e.g., USB
  • Experience with MATLAB and Python
  • Commitment to solid FW development process, including coding conventions, code reviews, unit-testing, QA, and system integration
  • Commitment to DevOps and Continuous Improvement/Continuous Development
  • Excellent written and verbal communication skills
  • Comfortable working in a focused fast-moving start-up environment
  • BS and MS, or Ph.D. in EE, CS, Math, or equivalent foundational technical subject
