Software Engineer – GNSS & Mission Systems
Glasgow (Hybrid)
Salary: £72,500–£95,000
The Company
Join a pioneering space technology organisation developing next-generation satellite missions focused on GNSS-based science and data services.
You’ll be part of a close-knit engineering team working at the intersection of spacecraft payloads, signal processing, scientific computing and cloud-based data delivery. Software, payload, RF and operations teams collaborate closely to ensure mission-critical data moves reliably from orbit to end users.
This is an opportunity to work on real spacecraft systems with tangible scientific and commercial impact.
The Role – Senior Spacecraft Software Engineer
We’re looking for a technically strong, curious and self-sufficient Senior Spacecraft Software Engineer to work across both flight and ground software for GNSS missions.
You’ll operate across system layers from embedded and payload-level software through to automation pipelines and cloud-based data infrastructure. The role blends signal processing awareness, systems thinking and practical software delivery.
This is high-impact work where autonomy and sound engineering judgement really matter.
Key Responsibilities
- Develop and maintain scientific and command and control software for GNSS satellite payloads
- Build and operate ground-based automation systems for data extraction, processing and delivery
- Support reliable and timely delivery of mission data from spacecraft to customer
- Collaborate with flight operations to troubleshoot and resolve mission issues
- Work closely with payload, systems and mission engineers to evolve software in line with scientific objectives
- Contribute to code reviews, testing and documentation to ensure traceability and robustness
- Support continuous improvement across performance, reliability and system understanding
About you
- 5+ years’ experience in software engineering within aerospace, scientific, communications or high-reliability environments
- Strong proficiency in C++ and/or Python
- Embedded systems or performance-sensitive software
- Solid understanding of DSP principles, ideally in RF or GNSS contexts
- Developing scalable backend or cloud-based data systems
- Ability to work independently and navigate complex technical challenges
- Collaborative mindset and clear communication style
Desirable Experience
- Experience with FPGA development (VHDL or HLS)
- Background in GNSS signal processing, GNSS-RO, GNSS-R or PNT algorithms
- Experience working on satellite payloads or spacecraft systems
- Familiarity with AWS or other cloud infrastructure platforms
- Experience building telemetry pipelines, monitoring or visualisation tools
- Contributions to open-source scientific or aerospace software
