Senior Application Security Engineer

We're looking for a Senior Application Security Engineer to join our expanding Information Security team. If you are a hands‑on AppSec expert who enjoys working deep in the SDLC, partnering with talented engineers and building security into fast‑moving delivery pipelines, this role gives you the space to make a real impact. You will join a modern, cloud‑native environment where squads genuinely care about secure engineering, and you will have the autonomy, tooling and influence to help them excel.

You will work alongside our existing Senior AppSec Engineer and Security Architect, strengthening our capacity and resilience as we continue to mature our security services. This is not a vulnerability management position. It is true engineering‑led AppSec, shaping secure design, embedding controls into CI/CD, operating core security services and getting into the technical detail of how our systems are built.

If you come from a startup or scale‑up background, thrive in cloud‑native environments and enjoy being the trusted expert for squads who want to do the right thing, you will feel at home here. You will help define how we secure applications across Azure, AKS, Databricks, Snowflake and more, with the freedom to influence processes, tooling and engineering culture.

At Our Future Health, our mission is to transform the prevention,detectionand treatment of conditions such as dementia, cancer, diabetes, heart disease and stroke. We're looking for people to join us on our journey. If you're looking for a new challenge where you can contribute to helping future generations live in good health for longer, then we're keen to speak with you.

What you'll be doing

Partnering with development teams across architecture, engineering and cloud to embed security into code, applications, Kubernetes and containerised workloads

Encouraging a shift‑left approach and promoting secure engineering practices

Implementing and operating code scanning to help developers identify and remediate vulnerabilities

Maturing our Secure Development Lifecycle, embedding security into CI/CD in GitHub Actions and strengthening development tooling

Advising on securing APIs and other high‑risk system components

Assisting with securing our Data Platforms including Databricks, Dagster, Snowflake and the wider cloud environment

Developing security policy as code using OPA or similar and gaining adoption across teams

Documenting security processes and low‑level designs for security tools and services

Contributing to security service documentation to support consistent delivery and operations

Assisting teams integrating with security tooling and ensuring smooth onboarding to security services

Supporting wider security initiatives including ISO 27001 activities and threat modelling

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.
