As a GNSS-RO payload software engineer, you will be part of a team laser-focused on delivering the critical data powering weather prediction models worldwide, by leveraging GPS / GNSS technology and advanced signal processing techniques in concert with our constellation of nanosatellites. You will build systems to collect and process GNSS signals in real-time, and you will have both the freedom and the responsibility to ensure that they are engineered to survive the harshest of environments: the vacuum of space. If you have both the drive to write high-performance software with a global impact, as well as a mastery of building rock-solid embedded systems, we'd love to hear from you.

Responsibilities of your role:

* Implementing real-time digital signal processing algorithms for GNSS and testing them on a custom embedded board

* Implementing/Testing the onboard data handling architecture with coordination with other payloads and the satellite bus.

* Implementing/testing low-level data transfer and processing functions that interact with the FPGA, RF front end, and peripheral sensors.

* Supporting the on-ground testing campaign through the documentation / execution / analysis / debug phases.

* Supporting commissioning and operation of payload after launch.

* Validating on-orbit performance of the payload by analyzing observation data and satellite telemetry.

Qualifications / Experience:

* Five or more years of hands-on experience working with C/C++ on large-scale software projects

* Familiarity with Linux, and system profiling tools like ptrace or strace

* Strong data analysis skills (statistics, hypothesis testing, data visualization)

* A detail-oriented personality; careful,

* ethodological, and persistent in tracking down problems

* Motivation for contributing to the development of a payload instrument that collects RO weather data

Strong candidates will also possess skills in one or more of the following areas:

* Experience designing an embedded Linux system, by using e.g. Buildroot / Yocto, or by customizing an existing distribution, and familiarity with bootloaders such as U-boot

* Experience with designing or implementing GNSS / GPS / GPS-RO / GNSS-R systems

* Experience with any field related to radio science, eg, RF design, EMI diagnosis/mitigation, etc.

* Experience with FPGA / digital circuit design

* Experience with Bash, Python, Ruby, Matlab, and / or Octave

* Experience writing and / or troubleshooting Linux driver / Linux kernel code

* Experience of developing spacecraft payload / bus components

* Experience in systems engineering, covering the design, implementation, verification, and operation phases
