Profile match
CesiumAstro is an American company founded in Austin in 2017 that builds active phased array communications payloads for satellites, aircraft and defence platforms. Its systems are software-defined and electronically steered, which lets a moving platform track several links at once without mechanical antennas, and the company manufactures them in house rather than integrating third-party subsystems. It sells mainly to defence customers and satellite operators, has raised venture funding from investors including Airbus Ventures and Lightspeed, and operates facilities in Austin, Colorado and the United Kingdom.

We are seeking a Senior Ground Software Engineer to join our dynamic team. The ideal candidate will have hands-on experience as a satellite operator, offering unique insights into the systems they will be building and integrating.

Your work will have a direct impact on the success of the company. You will work closely with the engineering team, program management to ensure the successful build and launch of our satellite. Element will be the largest, most powerful rideshare satellite in LEO. We’re launching eight of them in the next four years, starting with our first launch this year. Together, our small team will design, build, and iterate to reduce mass and cost while increasing performance, reliability, and manufacturability of a new generation of satellites. Let’s build!

JOB DUTIES AND RESPONSIBILITIES

  • Execute the design, development, and deployment of ground software systems for a new satellite system, including command and control, telemetry, telemetry database, and ground station software.
  • Rapidly execute to produce a simple, reliable ground system.
  • Implement real-time data acquisition, processing, and visualization systems for satellite telemetry.
  • Integrate and test ground software with satellite, ground stations, and network infrastructure.
  • Develop automated systems for satellite operation and ground system monitoring.
  • Conduct rigorous testing and validation of ground software, including simulations and real-world scenarios.
  • Troubleshoot and resolve software issues encountered during satellite operations.
  • Conduct tests with ground networks, spacecraft software and hardware simulators.
  • Collaborate closely with hardware engineers, satellite operators, and other software teams to ensure seamless integration and optimal performance.
  • Keep up to date with the latest advancements in satellite communication technology and incorporate relevant innovations into our systems.
  • Provide technical leadership and mentorship to the software development team, fostering a culture of excellence and continuous improvement.

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

  • Minimum of 5 years of experience in software engineering, with a focus on satellite ground systems.
  • Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
  • Demonstrated experience leading a software team through product development.
  • Prior experience as a satellite operator is required to provide clarity into the true needs of the system being developed.
  • Proficiency in programming languages including Python, Java, and C++
  • Experience in satellite test and data collection applications.
  • Strong knowledge of satellite communication protocols, such as CCSDS and CSP.
  • Familiarity with ground station hardware and RF communication principles.
