- Partner with DevOps and platform teams to implement secure cloud and infrastructure configurations
- Define and maintain security baselines across identity, device and workload trust
- Support the ongoing evolution of Zero Trust capabilities across the organisation

## What you'll bring to the team

- Proven experience in cloud security engineering, ideally within AWS environments
- Hands on experience working with modern security tooling such as EDR or XDR platforms, SASE solutions, identity controls or device trust models
- Experience building and managing Infrastructure as Code using tools such as Terraform or CloudFormation

- Comfortable working cross functionally with platform and DevOps teams to embed security into engineering processes
- Ability to translate security policy and risk requirements into scalable technical controls
- A mindset that embraces AI and new tools to adapt, learn and grow.
- An aptitude for identifying and managing risks. Whether you are a People Manager or an Individual Contributor, we are all leaders at Zip, therefore effective risk management is important to how we run our business and part of all our roles.
- Our values in your DNA: Customer First, Own It, Stronger Together and Change the Game
