Job Description

About the role:

At Holland \& Barrett, we're over a century old — and building like a startup. We've transformed into a fully cloud-native organisation, using Kubernetes, containers, serverless, and event-driven architectures. Now we're embedding security directly into how we build software, and we're looking for an Application Security Engineer to help lead that journey.

This is a role for someone who loves working with developers, not around them. Our ambition is simple: make the secure path the easy path. You'll help build an AppSec model that's automated, developer-friendly, and built into every stage of the SDLC.

The Role

As an Application Security Engineer, you'll be a trusted partner to our engineering teams. You'll work hands-on to integrate security into CI/CD pipelines, identify and fix vulnerabilities early, and help teams design and ship secure applications by default.

What You'Ll Do

Embed SAST, DAST, and SCA tooling into CI/CD pipelines

Perform code reviews, threat modelling, and application security testing

Work directly with engineers to remediate vulnerabilities and improve designs

Develop and promote secure coding standards and best practices

Deliver security training and workshops to engineering teams

Champion a culture of shared responsibility for application security

Key requirements:

Experience as an Application Security Engineer or similar role

Strong understanding of OWASP Top 10 and modern application threats

Hands-on experience with tools like Snyk, Checkmarx, Veracode, Burp Suite

Proficiency in at least one modern programming language (e.g. Python, Java, JavaScript)

Experience integrating security into CI/CD pipelines

Great communication skills and a collaborative, developer-first mindset

Why Holland \& Barrett?

Help shape AppSec from the ground up in a modern engineering organisation

Work with cloud-native technologies and forward-thinking teams

A purpose-led business focused on helping people live healthier lives

If you're passionate about building secure software and making security a natural part of development, we'd love to hear from you.
