ReOrbit is looking for a Project Manager – Mechanical Systems to lead all mechanical engineering activities for the SiltaSat GEO satellite.

This role ensures the successful design, integration, qualification, and delivery of mechanical subsystems under GEO‑mission constraints such as long‑term thermal stability, radiation exposure, and high‑reliability structural design.

It's an exciting chance to join a dynamic start-up, with the opportunity to make a real impact, to reach our goal of pushing the boundaries of space data transfer. 

Responsibilities

• Coordinate all mechanical domain activities across a GEO satellite project.

• Oversee development of:

  • Bus structures

  • GEO‑grade thermal control systems

  • Payload structures and thermal systems

  • Mechanisms and deployment systems

• Lead Mechanical AIT (Assembly, Integration & Testing) activities.

• Manage mechanical integration planning and interface coordination.

• Coordinate with subsystem leads and Work Package Managers.

• Identify and manage mechanical and structural risks, issues, and define mitigation strategies to ensure mission success

• Coordinate between procurement and engineering teams for mechanical hardware, including SOWs, specifications, and compliance tracking.

• Serve as custodian of the Mechanical Interface Control Document (MICD).

Skills and Requirements

• Bachelor’s degree in Mechanical Engineering; Master’s degree is an advantage.

• 5+ years of experience in flight hardware development within a space or aerospace company.

• Strong understanding of mechanical subsystem development for GEO or high‑reliability missions.

• Experience with MAIT processes, environmental testing, and mechanical qualification.

• Ability to interpret FEM and thermal analysis results.

• Experience with vibration and thermal‑vacuum testing of space hardware.

• Knowledge of safe transport and containerization of sensitive flight hardware.

• Strong understanding of mass, CG, and MI control for GEO platforms.

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, Bariloche, Argentina and Bengaluru, India.

Working at ReOrbit

At ReOrbit, we are focused on building a strong team as we believe nothing can be accomplished without innovative, humble and curious minds working together on a common goal. We’re all about fostering an inclusive, dynamic environment where equality and diversity are our strength. 

We offer

• Challenging but rewarding environment – you will thrive if you are always reflecting on how to make things better. Your ideas will be heard.

• Ambitious and supportive network of people, who are motivated to change the space industry, bringing expertise from both classic and new space .

• Benefits such as lunch vouchers, events, parties, occupational health care and additional health insurance - but most importantly a possibility to be a part of a unique and diverse team, connected by similar mindset and sense of humor. 

• We like to spend time together! You can choose activities whichever is to your liking – runOrbit, climbOrbit; become ping pong or board games champion.

• We support relocation and integration into Finnish society.
