Senior Python Security Engineer

About the role

We’re looking for someone passionate about Security Engineering with a core software engineering background to do something that is the first of its kind at this scale. We’re embedding a Security Engineer directly into a product squad where you’ll build a world‑class security control (our own Airlock), written in Python and designed from the ground up.

You’ll start fully embedded in our Research Enablement squad, acting as both Security SME and Software Engineer. Over time, your role will evolve into a roughly 50/50 split between hands‑on coding and broader security engineering across the organisation.

At Our Future Health we transform the prevention, detection and treatment of conditions such as dementia, cancer, diabetes, heart disease and stroke. If you’re looking for a new challenge where you can help future generations live in good health for longer, we want to hear from you.

What you’ll be doing

• Developing our TRE airlock as part of a squad, specifically the ‘airlock checks engine’ and the security checks that will run within it.
• Supporting product managers with shaping the airlock roadmap, ensuring security items are included alongside non‑security features.
• Contributing to developing the airlock policy specifying how to handle findings from airlock checks.
• Leveraging in‑house knowledge to enrich and enhance our SOC capabilities.
• Overseeing and supporting the operation of security tools, including Microsoft Defender and Microsoft Purview suites and Entra ID (previously AAD) for IAM, Identity Governance and Privileged Identity Management.
• Providing guidance and a level of oversight for vulnerability management and triage work.
• Documenting security processes and security tool low‑level design/configuration.
• Contributing to the development of security service delivery and operation documentation.
• Assisting tech teams with integrating their systems and services with security services and tools.
• Supporting cloud and application security engineers and the wider team with responsibilities, including achieving and maintaining ISO 27001 certification and threat‑modelling activities.

What you won’t be doing

• Working in a siloed environment with no freedom to make decisions.
• Working in a place where you can’t see the impact your expertise makes.

Requirements

• Proficiency in writing Python and ideally KQL.
• Comfortable working with Infrastructure as Code, ideally with experience of Terraform.
• Significant experience developing Python scripts/systems.
• Experience working directly with software engineering best practices: source control, unit testing, code reviews, design documentation, debugging, troubleshooting.
• Experience with Azure (ideally), AWS or GCP, Docker, Kubernetes, and Helm.
• Experience operationally managing software components once live, including observability, logging, metrics, error reporting, debugging and live incident management.
• Experience with Microsoft Sentinel, Defender and Purview suites and Microsoft Entra.
• Experience with SOAR tooling and automating security capabilities and operations.
• Experience in threat modelling.
• Ability to communicate with stakeholders and audiences outside your own team.
• Exposure to Agile working.
• Experience working in/with cross‑functional teams consisting of engineers, product, UX and non‑technical stakeholders.
• Desire to be part of a small fast‑paced security team.
• Relevant certifications such as Microsoft certifications (MS‑500, AZ‑500, SC‑200, SC‑300, SC‑400), CompTIA Security+, GIAC Security Operations Certified (GSOC), Cloud Security Alliance CCSK.

Benefits

• Salary from £75,000 per annum.
• Generous pension scheme – we invest in your future with employer contributions of up to 12 %.
• 30 days holiday + bank holidays.
• Enhanced parental leave.
• Cycle‑to‑work scheme – save 25–39 % on a new bike and accessories via salary sacrifice.
• Home & tech savings – up to 8 % off on IKEA and Currys products, spread over 12 months via salary sacrifice.
• £1,000 employee referral bonus.
• Well‑being support – access to mental health first aiders, 24/7 online GP services and an employee assistance programme.
• A great place to work – central London office in Holborn with flexible and remote working arrangements.
