Space system engineer

Space Systems Engineer

We’re looking for a Space Systems Engineer to join Vinterstellar AB and help us and our partners develop satellites and space systems. You’ll take a leading role in shaping architectures, coordinating subsystems, and making technical decisions that make a difference — both on Earth and in space.

About Vinterstellar

At Vinterstellar, we develop space technology, establish space-based infrastructure, and contribute to scientific research — all with the goal of expanding humanity’s understanding and use of space. In the long run, we want our work to help make human life in space a reality.

We are a startup with a solid customer base and a stable financial foundation — combining the agility and creativity of a young company with the reliability of an established one. We work closely, support each other, and share responsibility. Ideas grow in the group, and you’ll be involved from the early idea to final delivery. What matters is creating value — where and how you work is something we define together.

Your Role

You’ll work closely with our clients — leading players in satellite development and space innovation — to help define, build, and verify their systems. Your role will be to understand the big picture, align the parts, and ensure everything works as one.

What You’ll Do

• Design and propose system architectures to meet mission objectives
• Perform system-level analysis of spacecraft and their subsystems
• Define, document, and manage system requirements
• Coordinate development across subsystems and ensure seamless integration
• Support clients in selecting technical solutions and components
• Conduct trade-off studies and propose optimizations
• Prepare system-level documentation (e.g. ICD, VCD, FMECA)
• Contribute to test planning, verification, and validation
• Review designs and act as technical sounding board throughout the system life cycle

What We’re Looking For

• Experience with space systems engineering (or adjacent complex technical systems)
• MSc, PhD, or equivalent in aerospace, vehicle engineering, physics, mathematics, or similar
• Fluency in English and Swedish
• EU citizenship

Bonus If You Also…

• Live within commuting distance to Stockholm
• Enjoy solving complex problems in physics, systems, and design
• Are open to pitching in where needed — even beyond strict engineering tasks

Location & Benefits

• Office: Drottninggatan 33, Stockholm (hybrid work possible)

• Occasional travel may be required
