New Space Technical is proud to be partnering with an innovative and rapidly growing space technology company that is transforming the small satellite sector through cutting‑edge Earth observation solutions.

As demand for high-performance spaceborne imaging capabilities continues to accelerate, our client is seeking a Senior Systems & Mission Support Engineer to play a critical role at the intersection of engineering excellence, customer success, and mission delivery.

This is a unique opportunity for a technically confident engineer who thrives on solving complex system‑level challenges, leading customer‑facing technical discussions, and ensuring mission success in real‑world operational environments. You’ll become a trusted technical authority, helping customers integrate advanced space hardware into their platforms while influencing product improvements and shaping best‑in‑class support capabilities.

This is not a traditional support engineering position. The role sits at the intersection of systems engineering, customer integration, mission operations, and technical leadership. You’ll act as the technical owner for customer mission success, guiding payload integration activities, troubleshooting complex system interactions, and serving as the trusted technical interface between customers and internal engineering teams.

Working alongside multidisciplinary engineering teams and global customers, you’ll take ownership of high‑impact technical issues, drive system‑level investigations, and provide expert guidance throughout the customer mission lifecycle.

This role is ideal for someone who enjoys operating across disciplines, understanding how complex systems perform in real‑world environments, and playing a visible role in the success of space missions around the globe.

You’ll be expected to understand how complex multidisciplinary systems behave within customer spacecraft and mission environments, even when you do not have direct ownership of every subsystem involved.

• Act as the primary technical interface for customers throughout integration, testing, and operational phases.
• Lead complex technical discussions with confidence, providing expert guidance on system performance, integration, and troubleshooting.
• Proactively identify technical risks and ensure successful implementation of customer missions.
• Own and drive resolution of critical technical issues from investigation through to closure.
• Guide customers through payload integration activities and support successful deployment into larger spacecraft systems.

• Diagnose and resolve complex cross‑system issues involving hardware, software, electronics, and integrated systems.
• Analyse performance data and translate findings into actionable technical recommendations.
• Investigate anomalies and system‑level behaviours in operational mission environments.
• Take ownership of technically ambiguous challenges and drive structured resolutions.
• Develop a deep understanding of product behaviour within real‑world customer missions and operational environments.

• Work closely with engineering, production, and commercial teams to communicate customer requirements and technical challenges.
• Coordinate stakeholders across multiple disciplines to ensure timely and effective issue resolution.
• Support product improvements by feeding operational insights back into engineering and development teams.
• Translate customer challenges into actionable engineering feedback and improvement opportunities.
• Strengthen support, escalation, and knowledge management processes.
• Create and maintain technical documentation, troubleshooting guides, and lessons learned.
• Mentor junior engineers and contribute to a collaborative, high‑performance support culture.
• Champion continuous improvement initiatives that enhance both customer outcomes and product robustness.

• Bachelor’s degree in Engineering, Systems Engineering, Physics, Applied Science, or a related discipline.
• 5–8 years of experience in…
