How to Get a Better Space Sector Job After a Lay-Off or Redundancy

Being made redundant from a role in the UK space sector can be disheartening. Whether your work was tied to satellite design, launch services, ground systems, mission operations, or Earth observation analytics, the experience and specialist knowledge you've gained is still highly valuable. The UK government’s Space Strategy, increased commercial investment, and new launch initiatives across Cornwall, Scotland, and Wales continue to drive opportunities in upstream and downstream space technologies. This guide will help you relaunch your career in the UK space sector after redundancy.

UK Space Jobs Salary Calculator 2025: Work Out Your Market Value in Seconds

Why last year’s pay survey already misfires for UK space talent Ask a Satellite Systems Engineer wrestling with RF budgets, a Mission Operations Analyst shepherding cubesats at 04:00 UTC, or a Launch Vehicle Propulsion Engineer machining ablative liners in Cornwall: “Am I earning what I deserve?” The honest answer drifts faster than orbital debris. Since early 2024 the UK Space Agency released £1.6 billion of National Space Strategy funding, SaxaVord’s spaceport edged toward its first vertical launch licence, and Harwell Campus welcomed three VC‑fuelled in‑orbit‑servicing start‑ups. Each headline ratcheted hiring demand—and salaries. A salary guide printed in 2024 is already as dated as a Block II GPS ephemeris: no mention of the Scottish micro‑launcher premium, the AI‑earth‑observation bubble, or the sudden scarcity of flight‑dynamics controllers who can wrangle multi‑constellation mega‑swarms. To replace guesswork with data, UKSpaceJobs.co.uk distilled a clear, three‑factor formula. Feed in your discipline, UK region & seniority; you’ll get a realistic 2025 baseline—no stale averages, no vague “competitive” claims. This article unpacks the formula, explores the forces inflating space salaries, and sets out concrete steps to boost your value within ninety days.

How to Present Space Sector Solutions to Non-Technical Audiences: A Public Speaking Guide for Job Seekers

The UK space sector is expanding fast—from satellite communications and Earth observation to propulsion, launch services, and space sustainability. But as the technology becomes more complex, employers increasingly want space professionals who can explain it simply and persuasively to non-technical audiences. Whether you're applying for a role in engineering, mission control, data analysis, policy, or business development, your ability to present clearly is now seen as a critical soft skill. In fact, many interviews now include public speaking tasks that test your communication style, clarity, and stakeholder awareness. This guide offers a practical framework for structuring your space sector presentations, tips for engaging slides, storytelling techniques that work in interviews, and advice on answering common questions from executives, clients, and policymakers.
