• Strong command of SQL databases, data management, and Git‑based workflows.
• Experience in Agile/SCRUM environments.
• Familiarity with CCSDS or ECSS communications standards.
• Understanding of Ground Segment systems and mission operations.
• Experience with AWS or Azure cloud platforms.
• Awareness of software security best practices and coding standards.

What’s on Offer

• Opportunity to work with a talented, diverse, and international engineering team.
• Flexible working around core hours in a collaborative, supportive environment.
• Hybrid working model with an optional 9/75 compressed schedule.
• 25 days’ annual leave (increasing with service) + 8 bank holidays.
• Private healthcare, life insurance, and long‑term sick pay.
• Relocation assistance and visa sponsorship (where applicable).
