Company Details

In-Space Missions Ltd is a small space mission consultancy and spacecraft service provider based in Bordon, Hampshire. The company was formed in August 2015 and has grown since then, building a team of experienced Space industry professionals to support large and small Industrial partners, government agencies and academic institutions. In 2018 In-Space also announced its “Faraday” service – the first European commercial payload hosting service for which the first spacecraft, Faraday-1, is scheduled to launch imminently.

Company Background

In-Space has a fun and dedicated team who value hard work, a positive attitude and solution-focused thinking. We welcome applicants who will embrace their role and the flexibility required when working in a small company, and we reward dedication and results with a flexible environment to allow employees to flourish while meeting other requirements they may have in their life.

Role Overview

This is an exciting role which will suit an enthusiastic, self-starting individual who is happy to work on a range of activities from technical studies to small spacecraft systems and subsystems. They will be comfortable working as part of a team to deliver projects to a variety of customers including institutional, academic and commercial organisations. The successful individual will enjoy working as part of a team, is willing to flex their priorities to support others where necessary and is comfortable with a fast-paced environment. It will require someone who takes pride in their work, and can present a professional face to clients, suppliers and partners.

The role requires some knowledge and experience of designing, developing, building or operating small spacecraft, a willingness to learn and the ability to work with others to identify and resolve technical issues. Any interest, knowledge and/ or experience of thermal analysis and design would be an advantage. The right attitude is equally as important as background and experience.

While the primary responsibilities of the role lie in project delivery, the role may require some bid support and other reasonable responsibilities as required by the business. You will be actively encouraged to maintain a current interest in space industry developments and are expected to pro-actively identify business/technology promotion opportunities.

    – Sub-contractors and suppliers (including launch providers);
    – Users;
    – Customers;
    – Regulatory authorities.
  • Definition and/or management of requirements from Mission and System Level and derivation of technical requirements to subsystem and equipment level (with support from senior team members and specialists);
  • Perform or contribute to the thermal design, analysis and testing of space systems, including thermal modelling and data analysis, conducting engineering trade-offs, and assessment of in-orbit data;
  • Management and tracking of requirements through project delivery;
  • Derivation and management of system technical budgets and margins, with support from senior team members as required, including (but not limited to):
    – Mass budget;
    – Power budget;
    – RF link budget;
    – Thermal budget;
    – Delta-V budget.
  • Management of spacecraft interfaces;
  • Supporting the definition of spacecraft test and flight harnesses and MGSE/EGSE.
  • Management and execution of Validation and Verification activities at a subsystem and system level (including lab testing);
  • Collaboration with project managers to provide inputs to schedules; risk management plans; budget management and other project artefacts as required;
  • Technical pre-sales support to prospecting and bid activities;
  • Provision of technical inputs into technical consultancy activities such as customer supports, studies and R&D projects;
  • Supporting spacecraft operations.

You will report into a senior member of the Space Systems Team and your work will be prioritized in discussion with them.
