Job description

ReOrbit is seeking a visionary Head of Systems Engineering to lead our high-performing systems engineering team and drive the end-to-end architecture of our next-generation satellite platforms. In this highly senior role, you will take ownership of system requirements integrity, ensuring seamless alignment across all technical domains while fostering cross-functional collaboration and technical excellence.

This is a unique opportunity to step into a leadership position at the heart of a fast-growing, innovative company. You’ll play a pivotal role in shaping the future of mission‑critical space communications, where reliability, precision, and leadership are non‑negotiable from day one. If you thrive in technically complex, high‑stakes environments and are ready to mentor, inspire, and drive a team toward groundbreaking achievements, we want to hear from you!

Responsibilities

• Lead end-to-end system engineering for both space and ground segments, ensuring a unified architectural vision.
• Define technical direction and drive high-quality, system-level decision-making across all programs.
• Build, mentor, and lead a high-performing, multi-location system engineering team, while supporting its growth in alignment with company needs.
• Own and maintain requirements integrity—from customer needs through system, subsystem, and verification levels.
• Manage system budgets (mass, power, data rate, performance, margins) and ensure their consistency throughout the lifecycle.
• Coordinate and align system-level efforts across Payload, AOCS, Propulsion, Flight Software, AIT, Operations, and related domains.
• Establish and uphold system engineering processes, workflows, and standards for distributed teams.

Skills And Requirements

• Proven leadership in System Engineering teams for multiple spacecraft programs that successfully reached orbit.
• Full lifecycle expertise, from early design to in-orbit validation, including long-lifetime missions (LEO/GEO).
• Hands-on application of ECSS-E-ST-10C and related ECSS standards in real-world projects.
• Practical experience with the NASA Systems Engineering Handbook (SP-6105) in applied contexts.
• Leadership in system-level V&V and IV&V activities.
• Expertise in trade-offs, feasibility studies, and architectural decision-making under constraints.
• Ability to translate customer and operational needs into clear, actionable system requirements.
• Strong communication skills across engineering teams, management, and external stakeholders.
• Deep understanding of satellite subsystems and their interactions.
• Experience with satellite-level testing and validation.
• Production-oriented mindset with a focus on scalability and delivery.

What does ReOrbit do?

ReOrbit builds the foundation for the next generation of space applications by transforming satellites into truly intelligent, interconnected platforms, defined by software. Our satellite design philosophy revolves around the idea that satellites must network, communicate with each other and thus improve mission efficiency. How can this be achieved? Thanks to a flexible software-first architecture, where all these aspects are dealt with upfront in the mission concept, as integrated functionalities.

ReOrbit’s top-notch team of software engineers and system architects develop in-house software, procure hardware from the best-in-class suppliers, and seamlessly integrate the components to create flexible and secure satellites. Today, we are a rapidly growing company building a very strong multidisciplinary team to support our activities. We are headquartered in Helsinki, Finland with a subsidiaries in Bristol, UK and Bariloche, Argentina.
