Senior Security Engineer — Requirements, Architecture Inputsand Traceability for NATO with security clearance

Two jobs that are usually done by two people, done properly by one: keeping a portfolio of commercial applications running, and being the person who decides whether their design is safe. It is a senior post, and the security half is not decoration — you would own reference architectures, hardening baselines and the technical risk register entries that go...

A NATO organisation in Braine-l'Alleud is looking for a principal solution engineer to lead the architecture of complex communications solutions — the deployable, dispersible and highly mobile kind, where power, wireless and satellite all have to work together in the field. This is a senior post: you would set the standards other projects build to. What...

A multinational defence organisation runs its security tooling on Linux, and needs an engineer to install, harden, automate and keep it available — working inside a change-controlled environment where an unexplained fix is not a fix. What you would be doing Installing and monitoring Linux operating systems and the applications that run on them, to the...

Plenty of security posts are about advice. This one is about hands on hardware and software: standing up boundary protection, detection, monitoring and forensic tooling, integrating it into existing environments, testing it properly and handing it over to operations in a state someone else can run. The tooling is named rather than hypothetical, and the work...

Every secure login, signed document and trusted connection across a large international organisation rests on its public key infrastructure. A multinational defence organisation is looking for a senior engineer to run that infrastructure day to day, design what comes next, and be the person other teams escalate to when certificates stop behaving. What you...

Threat intelligence is only as good as the platform carrying it, and this one carries a lot. You would own the engineering behind a defence alliance's core instances of an open-source threat-intelligence sharing platform in Mons, Belgium — keeping them running, extending them, and helping the people who live in them day to day. Your immediate colleagues...

Cyber visibility lives or dies on its data, and this role owns that end of it. Under the team lead you would analyse the sources that describe assets, configurations and vulnerabilities, validate what has been onboarded, and lead the technical discussions about correlation and procedure rather than waiting to be told. It is not a back-room post. A real part...

This is a hands-on senior engineering post on a cyber defence monitoring platform, and it has two halves that most roles keep apart. One is development, largely in Splunk: dashboards, data models, searches, automation. The other is operational — supporting the operational team that uses it every day and translating what they need into something buildable....
