Job description

Senior Spacecraft 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

What’s on Offer

• Salary: £72,500–£95,000 (DOE)
• Location: Glasgow, Scotland
• Hybrid working environment
• High autonomy and technical ownership
• Opportunity to work across flight, payload and ground systems
• Join a highly skilled communications systems team
• High-impact, meaningful work
• Cross-functional engineering exposure
• Career growth
