About the Role
PortSwigger exists to enable the world to secure the web. We build the tools practitioners trust, the knowledge that trains security professionals, and a community that makes anyone who cares about security better, so anyone can make the internet safer. Our products are crafted with care, backed by deep research, and we lead through generous innovation: winning by setting the bar higher and sharing what we create, turning commercial success into wider positive impact. Our culture is deliberately built and protected with the same care we put into everything we make. We default to trust — brilliant people doing brilliant work, free from micromanagement. We aim for excellence, and we do it with care; performance and compassion go hand in hand. Joy, mastery and purpose belong together here and if the work stops feeling good, we take that seriously. We use AI across every team as a professional default and invest in the tools that make that possible - not an optional extra, but a genuine part of how we approach work and make better decisions.

The Technology tribe builds and runs the platforms, systems and tools that power everything at PortSwigger. From technical direction to day-to-day reliability, they shape the foundation that helps our products shine and our teams move fast with confidence. They embed secure-by-default thinking into everything we do. From managing risk to protecting our systems and data, they take ownership of keeping PortSwigger safe as the company scales. They work hand in hand with Product and Engineering to make smart pragmatic architectural choices. Whether it's levelling up our platforms, simplifying how teams ship or solving hard cross-cutting problems, they make it easier for Swiggers to deliver incredible work at scale.

As a Platform Engineer, you will design and operate cloud-native infrastructure across AWS, Azure, or GCP. You will build and maintain containerised environments using Docker and Kubernetes, implement infrastructure as code using tools such as AWS CDK or equivalent, and develop and improve CI/CD pipelines to enable safe, frequent delivery. Automating manual processes to reduce toil and improve system resilience will be key, as will operating and scaling distributed systems with reliability and observability in mind. You will collaborate closely with product engineering teams to provide robust platform capabilities, share knowledge, review work, and contribute to a high-performance engineering culture.
