Job description

Senior Systems Engineer

Connecticut Air Charter, LLC

An exciting opportunity has arisen for an experienced Senior Ground Segment Systems Engineer to join a leading space engineering team developing the infrastructure and software that enable mission‑critical spacecraft operations. This is a high‑impact role with significant autonomy, where you’ll lead the development of ground systems from concept through to maintenance, shaping the technology that supports safe and efficient mission control. You’ll act as a bridge between Mission & Systems Engineering and Operations, ensuring that ground systems are robust, integrated, and ready to deliver across all phases of flight operations.

This role suits an engineer with a strong understanding of ground segment architecture and experience across multiple missions, who’s ready to take ownership and mentor others in a fast‑paced, innovative environment.

Visa sponsorship and relocation support can be considered for this role.

Key Responsibilities

• Lead and contribute to the development of ground systems including Mission Control, Mission Planning, and Ground Station Interface Systems.
• Define ground segment requirements and oversee delivery of specific components.
• Act as technical lead or product owner, interfacing with both internal teams and external suppliers.
• Follow Agile (SCRUM) methodologies to deliver on requirements, schedule, and quality.
• Develop and maintain project documentation including requirements, V&V plans, test procedures, and reports.
• Support verification and validation, system integration, and simulation campaigns.
• Provide technical support and training to operations teams using ground systems.
• Troubleshoot, maintain, and enhance operational ground segment components.

What You’ll Bring

• Degree in Computer Science, Telecommunications, or a relevant engineering discipline.
• Minimum 5 years experience in satellite ground systems engineering.
• Strong understanding of the ground segment architecture and its core components (mission control, mission planning, and communications systems).
• Solid grasp of requirements engineering, system integration, and verification and validation.
• Excellent communication and reporting skills, comfortable collaborating with international teams.
• Fluent in English, written and spoken.

Desirable Skills

• Experience with Mission Control Systems (preferably SCOS-2000-based).
• Knowledge of automation and mission planning systems.
• Familiarity with ground stations and antenna communications.
• Understanding of satellite operations and product lifecycle management.
• Experience with ECSS and CCSDS standards.
• Programming experience in C++ or Java.
• Linux system administration and scripting skills (shell, make, etc.).
• Experience working in Agile/SCRUM environments.

Whats On Offer

• Work with a talented, diverse, and international engineering team on cutting‑edge space technologies.
• Flexible and hybrid working options around core hours.
• Optional compressed working pattern (9/75).
• 25 days annual leave (increasing with service) plus bank holidays.
• Private healthcare, life insurance, and long‑term sick pay.
• Relocation assistance and visa sponsorship (where applicable).
• State‑of‑the‑art office and cleanroom facilities.
• Regular team and social events in a collaborative, supportive environment.

If you’re an experienced systems engineer ready to take technical ownership of ground segment development for next‑generation space missions, we’d love to hear from you.
