Ground Segment Control Software Engineer

Lumi is on a mission to make the future of space more sustainable. We’re starting by solving the space debris problem with lasers, using satellite laser ranging.

We’re looking for an experienced software engineer to join our Control & Automations Software division. You’ll work alongside a talented team who develop high-performance control and automation systems for satellite laser ranging stations.

Your day will look like:

• Writing clean, maintainable code, with an emphasis on delivery over perfection.
• Implementing DevOps practices to streamline development workflows, automate system deployments, and manage continuous integration and delivery (CI/CD) pipelines using GitHub.
• Troubleshooting and fixing bugs in our remote control systems platform.
• Contributing as an early team member making a real impact on our product and company culture.

You should apply if you…

• have five or more years of industry experience developing software for commercially critical applications.
• have strong proven experience using a system programming language, such as C/C++, Rust, or Go, and a high-level language like Python.
• have used containerisation and orchestration tools (e.g., Docker, Kubernetes) for deploying and scaling applications.
• have a solid understanding of device communication protocols (serial, CAN, TCP/UDP, OCP UA) and proven ability to design or integrate custom messaging layers.
• have experience with real-time or near real-time data handling, including buffering, queuing, and streaming large volumes of sensor data across distributed environments.
• are curious about software engineering, and enjoy learning new things.

It’s a bonus if you…

• actively participate in or contribute to relevant open-source projects.
• have experience writing low-level device drivers, in C or C++, are familiar with the ASCOM protocol, or other astronomy-specific protocols.
• know about security best practices for remote machine management, including certificate management, intrusion detection, and device authentication.
• know about FPGA coding, integrated circuit architecture, or the implementation of IoT solutions.
• have developed with real-time operating systems (RTOS) for developing time-critical applications in embedded systems.

If you don’t think you tick every box, that’s fine! Studies show minority groups, including women and people of colour, might hesitate to apply if they don’t meet all the requirements. Lumi is dedicated to creating a diverse and welcoming team. If you’re curious about the role and want to learn and grow with us, please apply! We’d love to hear from you.

Please note: For this role we are unable to sponsor visa applications and you must have the right to work in the UK to apply. Together, we’re going to empower Earth’s future prosperity.
