Job Description

About the role

This is a chance to join a small but growing security team at a pivotal moment. We're building security in the PortSwigger way: thoughtful, low friction, high trust. This role is about bringing your perspective, experience and drive to help shape what that looks like.


You'll work alongside experienced peers to collaboratively own security across our infrastructure, systems and culture. This isn't about hierarchy or titles. It's about impact, curiosity and partnering to build something that scales well and feels right.


You'll be hands on with architecture, tooling, policy and incident response. You'll enable teams to move quickly and securely, bringing clarity to complex problems and designing systems that work long after you're done with them.

What you'll be doing

Collaborating with your teammates to take ownership of security across the business from hardening and monitoring to governance and incident response Designing and evolving secure architectures using defence in depth and threat modelling principles across cloud, networks and endpoints Driving vulnerability management and scaling tooling such as CSPM, SIEM, IAM and endpoint protection to manage risk effectively Contributing to compliance efforts including ISO27001, supplier security and data privacy, helping ensure we remain audit ready Building lightweight processes that make it easy for teams to do the secure thing by default Sharing ownership of incident response including triage, coordination and postmortem analysis Partnering with engineers and product teams to embed secure thinking into design and delivery Keeping pace with emerging threats and contributing to strategic conversations about how we evolve our approach
