Why this role matters

Security is the fastest-growing part of our business. In a world where the bad guys are getting smarter and cyber-attacks are on the rise, it’s more important than ever that our security teams bring their A-game.

By joining us as a Security Researcher, you’ll be able to help us change the world of the better. You’ll be analysing and supporting secure applications and systems to combat cyber-crime and threats to the UK’s Critical National Infrastructure for both BT and our customers.

What you'll be doing

Joining a team of world class engineers, you’ll be working on a huge range of research projects. They’re pretty varied and cover everything from mobile applications to IoT kit.

And most of our unique products push the boundaries of existing technology, so you can rest assure that you’ll always be at the forefront of the industry.

Day to day you’ll :

  • Reverse engineering an application
  • Analysing the network traffic of an application
  • Identifying data storage content and formats of an application
  • Develop and deliver completely bespoke tools, from inception right through to production
  • Design, develop, test, deploy and continually improve our software and tools to keep us ahead of the cyber-criminals
  • We work across a number of different technologies, but we don’t expect you to be an expert in everything that’s what the team are here for and we’ll support you learning additional skills too.

    However, you would need to be a hands on practitioner in at least one of the technology areas we work in.

    These include :

  • Reverse engineering of Arm binaries & Smali
  • Analysing file systems
  • Analysing network traffic
  • The latest security measures and countermeasures
  • Analysing malware on mobile platforms
  • We'll also need to see these on your CV

  • A degree (or equivalent) in a relevant field of study
  • Experience working to multiple deadlines
  • Knowledge of mobile security models
  • Reverse engineering using tools such as IDA, Hopper & JEB
  • Network analysis using tools such as Wireshark, Burp Suite & Fiddler
  • Forensics knowledge
  • Arm assembly
  • Compiled and scripted languages; e.g. C, C++ (STL, multi-threaded / real-time), C#, Objective-C, Swift, Java / JEE, Python, JavaScript, Go, Bash, PowerShell
  • Software lifecycle, issue management and version control technologies and practices; e.g. Git (using Git Flow), Bitbucket, JIRA, Scrum / Kanban.
  • Due to the nature of the work our team undertake, you’ll need to be security cleared to be able to join us. This means you’ll need to meet our residency criteria*

    Why choose us?

    Security is part of our DNA we’ve been at the forefront of cyber security development ever since our very own Tommy Flowers carried out ground-breaking work in encryption with Alan Turing during the Second World War.

    And because we’ve been doing this for such a long time, we’re a truly trusted partner, so by joining us you’ll have the opportunity to work on projects and accounts that aren’t open to others.

    We’re looking for outstanding people to join our team of 3,000 experts. They shield BT and our customers - including nation states, government, armed forces, emergency services, banks and retail outlets - to keep them safe from cyber-attacks.

    We work closely with global law enforcement agencies too, all in support of a safer connected world.

    By helping us protect the entire country, the work you do will benefit everyone in the UK.

  • You must be born or naturalised British Citizen and one of your parents must be a British Citizen or have substantial ties to the UK.
  • Candidates must normally have been a resident in the UK for the nine of out the last ten years prior to their application and this is particularly important if you were born outside of the UK.

    You’ll still be considered if you have, for example, served overseas with HM Armed Forces or in some other official capacity as a representative of Her Majesty’s Government, studied abroad or lived overseas with your parents.
