We are expanding our security engineering team and looking for someone who enjoys solving practical security problems, learning new tools, and working across a modern Microsoft environment. You will help strengthen our detection and response processes, improve cloud security in Azure, and support engineering teams in building safely and responsibly. This is a hands‑on role that covers a mix of operational work and engineering improvements.

* Contribute to the optimisation, tuning, and maintenance of SOC tools
* Investigate suspicious activity and support incident response when needed
* Contribute to cloud hardening in areas such as identity, access, networking, storage, WAF, and logging
* Participate in security risk assessments, threat modelling, and vulnerability management
* Support penetration testing by organising test execution, reviewing results, and helping teams prioritise fixes
What we’re looking for
* About 3–5 years in a security engineering or internal security team role
* Practical understanding of cybersecurity fundamentals and common risks
* Experience with infrastructure‑as‑code (Bicep, Terraform, or similar)
* Familiarity with PowerShell for automation or general scripting tasks
* Good problem‑solving skills and attention to detail
* Ability to work in a fast‑moving environment with competing priorities
* Some knowledge of frameworks such as SOC 2, ISO 27001, GDPR, or NIST CSF
* A growth mindset and curiosity to keep learning
How we reward you
* Competitive bonus scheme – designed to reward and recognise high performance
* Flexible benefits budget – a pot to fund meaningful benefits for you such as hormone or fertility testing, cancer screening, neuro‑diversity coaching, or anything that matters to you
* A range of salary‑sacrifice options to help you make tax‑efficient savings on electric cars, nursery schemes, home and tech goods
* Around‑the‑world scheme – 3 months work‑from‑anywhere scheme
* Mental wellbeing support – access therapy and mental health sessions through Spill
* Learning and development – £1,000 personal development budget to help you grow in your role
* Private health care – enjoy all the benefits AXA has to offer, including reduced gym memberships and medical history disregarded
* Medical cash plan – to help you with the costs of dental and optical expenses
* Life insurance and income protection – four times your annual salary for peace of mind
* Matched pension contributions up to 5%
* 25 days holiday – plus bank holidays, well‑being days, and volunteering days
* Enhanced parental leave – enhanced maternity, paternity, and adoption pay
