Full Job Description

At PortSwigger we choose to be in the office five days a week because we believe being on-site has several key benefits. We see real value in proximity: it enables “high-bandwidth” communication, speeds up feedback loops, and helps innovation happen naturally through ad hoc chats, quick clarifications, and spontaneous problem-solving. Being in-person also strengthens our connections and culture. Shared lunches, casual conversations, and day-to-day interactions build trust and a social fabric that creates a sense of belonging, something that’s simply easier to develop face-to-face. It also helps us to maintain a healthy work–life boundary. Having a dedicated workspace creates a clear separation between professional and personal life, making it easier to switch off at the end of the day. This isn't a typical software developer role, and our hiring approach isn't typical either. We hire with intention, thinking about people in combination rather than in isolation. The people joining now will shape the team's culture, its ways of working, and the standard of engineering we hold ourselves to. As a product-minded software engineer, you'll have real ownership from day one: the autonomy to shape your work, the freedom to experiment, and the responsibility to deliver meaningful outcomes. PortSwigger products are trusted by hundreds of thousands of (ethical) hackers, developers, and security professionals worldwide. As a profitable, majority founder-owned company, we build for the long term — investing steadily in our products and our people. In this role, you’ll help shape the future of web security through the features you design, build, and evolve; thinking not just about how to implement, but what to build and why. We also invest in an environment where engineers can learn fast and work at the edge of what’s possible with AI. That means giving you the time to explore, the right tools and practical support, so you can experiment responsibly, share what you learn, and turn
