Job description

Overview

Join to apply for the Product Engineer role at PortSwigger. This isn’t a typical software developer role. As a Product Engineer, you’ll have real ownership from day one, with the autonomy to shape your work, the freedom to experiment, and the responsibility to deliver meaningful outcomes. Burp Suite is trusted by hundreds of thousands of (ethical) hackers, developers, and security professionals. In this role, you’ll help shape the future of web security through the features you design, build, and evolve. This is an opportunity to do high-leverage, high-impact work in a supportive environment that values both excellence and care. You’ll solve real, complex user problems and build robust, user-ready features that deliver meaningful impact. You’ll also influence what we build and why. More importantly, you’ll be trusted to think boldly, learn fast, share your work early, and make great decisions in service of our users. You’ll join a team of curious, driven, and humble engineers who take pride in building something that truly matters.

What You’ll Do

• Solve complex technical problems with creativity and sound judgment
• Contribute across the stack (frontend, backend, infrastructure) as an expert generalist, balancing breadth with depth and adapting quickly to new domains and tools
• Talk to users and use insights to drive decisions
• Share your work early and invite input from peers and cross-functional partners
• Collaborate with designers, researchers, marketers, and perform pair programming activities with other engineers
• Proactively seek and give feedback with candour and care, helping create a culture of continuous improvement
• Role-model PortSwigger values and raise the bar through your mindset, behaviours, and technical standards
• Leverage AI tools (e.g. LLMs, agents, copilots, ML APIs) to improve developer workflows and user-facing features
• Explore how AI can be meaningfully integrated into our products to solve real-world security challenges

Requirements

We’re looking for engineers who care more about outcomes than output—and who want to make a lasting personal impact through their work.

Technical Excellence

• You design and implement high-quality, scalable features from start to finish
• You make sound architectural decisions and navigate trade-offs with confidence
• You create clean abstractions and intuitive designs
• You build codebases others want to contribute to and evolve
• You adapt quickly to new tools, frameworks, and domains, thriving as an expert generalist

Judgment and Ownership

• You deliver work that matters and strive for excellence
• You are a safe pair of hands who thrives in ambiguity and enjoys owning a problem end-to-end
• You ask clarifying questions and constructively challenge assumptions to strengthen outcomes
• You are comfortable prototyping, iterating, and making trade-offs

Product Thinking

• You have experience in product-led or startup-like teams
• You think beyond code—curious about users, product strategy, and business impact
• You work with urgency, prototyping and validating ideas quickly with users to accelerate learning

Growth and Collaboration

• You show a growth mindset by embracing feedback, seeking challenge, and pursuing continuous learning
• You thrive on learning new things, from unfamiliar domains to new tools and workflows, and apply them directly to improve outcomes
• You empower others by bringing empathy, humility, and clarity to team discussions
• You build strong relationships across functions, supporting peers and celebrating wins together
• You give constructive feedback effectively, with candour and care

AI Literacy

• You confidently use and adapt modern AI tools (e.g. Claude Code, LLMs, copilots), treating them as agentic coding partners—knowing when to trust, adapt, or override their outputs to build high-quality solutions
• You're curious about how to apply AI to improve developer experience, user value, or product outcomes

Why Join PortSwigger?
