Overview

The Microsoft Threat Intelligence Center (MSTIC) have unique optics into end-to-end attacks and how different stages manifest across our telemetry: we join the dots and show the art of the possible. The Threat Intelligence Product Research team research and develop new detection capability through novel correlation and analysis ideas, embed Threat Intelligence, and then achieve global impact by partnering across the company to make these a reality in customer-facing security solutions. We’re recruiting a Principal Security Researcher with deep expertise and a track record of successful security research delivery to tackle hard problems related to the discovery of threat actors targeting Microsoft and its customers. You’ll be working to analyse vast amounts of telemetry from multiple different products then designing and prototyping detections and disruptions to protect millions of customers. You’ll also be working closely with the threat intelligence analyst community to build new insights and automate tracking of threat actors through your deep expertise in security product and platform internals. Security Research is a broad field, and we welcome interest from accomplished security researchers with a wide variety of prior expertise. Our primary focus is on threat intelligence-based detection through analysis of telemetry sent to the cloud or generated by internal cloud services – so a desire to work at that level and build guru-level knowledge of Kusto and KQL is essential. Our current areas of focus are related to Identity, Cloud Apps and Microsoft Cloud, but there is scope to research and join activity over a wide range of technologies and data sources.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

Maths for Space Jobs: The Only Topics You Actually Need (& How to Learn Them)

UK space careers can look intimidating from the outside. Job adverts mention “systems engineering” “mission assurance” “GN&C” “RF” “payloads” “flight dynamics” “verification” “ECSS” & suddenly you’re wondering if you need a maths degree just to apply. You don’t. For most UK space jobs, the maths you actually use clusters into a handful of practical topics that map directly to real work across satellites, launch, ground segment, downstream data, mission ops & space software. This article strips it down to what matters most for job readiness plus a 6-week learning plan, portfolio projects & a resources section you can use immediately. UK space is also actively focused on growth & skills. The government’s National Space Strategy sets ambitions to grow the UK’s space ecosystem & spread employment across the UK. The Space Sector Skills Survey 2023 highlights recruitment challenges plus the importance of new skills & technologies including AI & ML. Recent industry reporting also estimates UK space industry employment at 55,550 FTEs plus wider supply-chain jobs. So learning the right maths is not an academic exercise. It’s a practical way to widen the roles you can credibly target.

Neurodiversity in UK Space Careers: Turning Different Thinking into a Superpower

The UK space sector has quietly become one of the most exciting places to build a career. From small satellites & launch services to Earth observation, navigation, in-orbit servicing & space data startups, the industry needs people who can solve hard problems in smart ways. Those people are not all “typical” engineers or scientists – and that’s a strength, not a weakness. If you live with ADHD, autism or dyslexia, you may have been told your brain is “too distracted”, “too literal” or “too disorganised” for precision work in the space sector. In reality, many of the traits that made school or previous jobs difficult can be major assets in space engineering, mission operations & space data roles. This guide is written for neurodivergent job seekers exploring UK space careers. We’ll look at: What neurodiversity means in a space industry context How ADHD, autism & dyslexia strengths map to common space roles Practical workplace adjustments you can request under UK law How to talk about neurodivergence in applications & interviews By the end, you’ll have a clearer sense of where you might thrive in the UK space sector – & how to turn “different thinking” into a genuine superpower.

Space Sector Hiring Trends 2026: What to Watch Out For (For Job Seekers & Recruiters)

The UK space sector is no longer a niche curiosity. It is now a strategic industry worth billions, employing tens of thousands of people across nearly 2,000 organisations – and it has been growing faster than the wider UK economy for years. At the same time, employers report serious skills shortages, especially in software, data and systems engineering, with recruitment and retention now cited as key barriers to growth. For job seekers, this is encouraging – but it does not mean every space application is an easy win. For recruiters, competing for talent with tech, defence, energy and finance is only getting harder. This article, written for www.ukspacejobs.co.uk , explores the space sector hiring trends to watch in 2026, aimed at both: Job seekers searching for terms like “space jobs in the UK”, “satellite jobs UK”, or “space engineer roles”; and Recruiters and hiring managers interested in “space sector hiring trends” and “space recruitment UK”.
