Working in our Chief Operating Office (COO)

Our COO Teams are the engine that powers Open Cosmos’ operations. This division brings together mission management, supply chain, and quality & product assurance to make sure every mission is delivered smoothly, reliably, and to the highest standards.

Our Mission Management team is at the heart of delivering Open Cosmos’ space mission services.

It’s a dynamic, collaborative team that turns complex requirements into successful missions.

What will you be doing?

As a Senior Mission Manager, you’ll take ownership of some of our most ambitious and technically complex missions. From early concept through to launch and in-orbit operations, you’ll be the person bringing it all together, aligning teams, navigating complexity, and ensuring delivery that meets the highest standards.

You’ll be:

  • Owning the full mission lifecycle — from initial requirements through to launch and in-orbit commissioning

  • Translating complex mission concepts into clear, executable plans across timelines, resources, and budgets

  • Leading multidisciplinary teams across systems engineering, AIT, manufacturing, supply chain, and mission operations

  • Acting as the main point of contact for customers, partners, and stakeholders — building trust and maintaining alignment

  • Managing expectations through clear communication, structured reporting, and proactive risk management

  • Overseeing the integration of mission elements including launch services, ground segment, and regulatory approvals

  • Ensuring missions meet technical, contractual, and regulatory requirements at every stage

  • Identifying risks early and driving mitigation and recovery plans to keep delivery on track

  • Supporting continuous improvement of how we deliver missions as we scale

  • Mentoring and guiding other mission managers, helping raise the bar across the team

  • Contributing to proposals, mission planning, and cost modelling to support future growth

What You’ll bring

  • Strong grasp of project delivery in complex, multidisciplinary environments, ideally within space or high-reliability engineering

  • Solid understanding of satellite systems, payloads, or mission operations

  • Ability to balance scope, schedule, cost, and risk across multiple parallel workstreams

  • Confidence navigating ambiguity and making informed decisions in fast-moving, high-stakes environments

  • Skilled at stakeholder management, able to influence, align, and manage competing priorities

  • Commercial awareness, including contracts, supplier coordination, and delivery frameworks

  • Familiarity with regulatory and compliance considerations in the space ecosystem

  • Clear, structured communication, able to simplify complexity for different audiences

  • Comfortable using project management tools (e.g. MS Project, Jira, or similar)

  • A proactive mindset, spotting risks early and acting before they become issues

  • A collaborative approach, building strong relationships across teams, locations, and partners

  • Resilience and adaptability, staying focused and effective under pressure

For this role you can be based in any of our locations.

Where to Advertise Space Jobs in the UK (2026 Guide)

Where to advertise space jobs UK in 2026: the specialist boards, agency channels and community routes that reach satellite, propulsion and launch talent. The candidate pool spans satellite engineers, propulsion specialists, mission analysts, ground segment software developers, space systems architects and commercial space professionals — a highly specific multidisciplinary community that general job boards are poorly equipped to reach. The strongest space candidates are often embedded in ESA programmes, academic research groups, UK Space Agency-funded projects or established primes, and move between roles through sector-specific networks, industry bodies and conference communities rather than mainstream platforms. This guide, published by UKSpaceJobs.co.uk, covers where to advertise space industry roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Space Jobs UK 2026: What to Expect Over the Next 3 Years

Space Jobs UK 2026: roles, salaries and the UK space sector hiring trends shaping satellites, launch, Earth observation and space data careers. The UK space sector is in the middle of something that feels genuinely historic. A combination of government commitment, private capital, and technological progress has transformed Britain's position in the global space economy from a capable but secondary player into a nation with serious sovereign ambitions — and a jobs market that is expanding to match them. This is not the space industry of previous generations, defined by a small number of government agencies, a handful of prime contractors, and career pathways accessible only to a narrow band of elite engineers and scientists. The new space economy is broader, faster-moving, and more commercially driven than anything the sector has previously seen. Satellite manufacturing has been democratised by small sat technology. Launch is becoming domestic. Space data is flowing into applications across agriculture, insurance, climate monitoring, maritime, and defence at a scale that is creating entirely new categories of commercial hiring. And the defence and national security dimensions of space have elevated the sector's strategic importance to a degree that is driving sustained public investment in the talent pipeline. For job seekers, the UK space jobs market of 2026 represents an opportunity that is both more accessible and more technically demanding than at any previous point. The candidates who will thrive over the next three years are those who understand where the sector is heading — which programmes are moving from development into operation, which technologies are defining the architecture of modern space systems, and how the definition of a space career is expanding well beyond the spacecraft engineering core toward a much wider ecosystem of roles across the full space value chain. This article breaks down what the UK space jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career at the leading edge of one of the most exciting sectors in the UK economy.
