Job description

Overview

Who are we?

We're the creators of Burp Suite, the world's leading software for web security testing, and we're pioneering its future with an AI-first engineering approach. We are a dynamic team striving for excellence, embracing the cutting edge of technology to solve real-world security problems. Our culture is built on continuous self-improvement and personal development. We foster a collaborative and inclusive environment where your growth is our priority.

What you'll be doing

From day one, you will be an active contributor, programming alongside experienced software developers on real production code and helping us build the next generation of AI-driven security tools. Forget rigid, predetermined paths; you will be expected to direct your own learning, take ownership, and make a tangible impact quickly. You\u2019ll:

• Solve meaningful problems: Tackle complex, real-world challenges using computer science fundamentals and an AI-augmented approach.
• Build with in-demand technologies: Work with tools and frameworks like Java, .NET, and React, and gain experience with platforms like AWS and Kubernetes.
• Master AI-driven development: Learn how to leverage AI-powered coding tools, prompt engineering, and agentic workflows to create clean, maintainable, and efficient code.
• Accelerate with Agile: Practise agile development techniques, to build and ship high-quality software at pace.

How we'll support you

We\u2019re deeply invested in your learning, and we\u2019ll give you the structure and support to go far, fast. Our grads make rapid progress because they're embedded in real teams and mentored by experienced engineers.

• Dedicated Technical Mentorship: You\u2019ll be paired with a senior engineer who will help you set and achieve ambitious goals.
• Hands-on Learning: You\u2019ll learn through working with experienced engineers on real projects - gaining practical skills and insights from day one.
• Variety: You will have an opportunity to work on different products across varying technological stacks.
• A Supportive Start: A buddy will help you navigate your early days and make sure you feel at home.
• Resources for Growth: We\u2019ll support you with whatever you need - books, certifications, or access to cutting-edge tools.
• A Welcoming Community: From grad socials and lunches to company-wide events and special interest groups, you'll have plenty of opportunities to connect and thrive.

Requirements

What we're looking for

We're searching for curious and driven individuals with a passion for tackling challenging problems - who are willing and equipped to use AI as a key part of how they learn, build, and solve.

Technical & Cognitive Prowess

• Strong Foundations: You're on track for (or have recently achieved) a first-class degree (UK) or a GPA of 3.7-4.0 (US) in Computer Science, Software Engineering, or a related STEM subject from a leading University. You have previously achieved a minimum A*AA at A-level with an A* in Maths or Further maths, or equivalent. You understand core programming principles, data structures, and algorithms.
• Practical AI Experience: You have practical experience beyond your coursework that shows your passion for technology. You have used AI-powered development tools (e.g., agentic coding tools like Claude Code, OpenAI Codex, Cursor, Windsurf, etc.) to enhance your personal projects, improve code quality, or learn more efficiently.
• Advanced Problem-Solving: You exhibit strong analytical and critical thinking skills, with an ability to break down complex problems and a genuine excitement for applying computer science fundamentals to new challenges.
• Quality-Focused Coding: You can recognize and articulate the qualities of well-structured, high-quality code and can write clean, logical, and well-tested code in at least one language.

Cultural Alignment

• Curiosity & Drive: You're driven by a desire to understand the "why" behind technical decisions, and you actively pursue knowledge - especially in fast-moving areas where clear resources may not yet exist. You learn independently and see AI not as a niche skill but as a core part of how modern engineers learn, build, and solve.
• Growth Mindset: You see challenges as learning opportunities and show persistence when tackling difficult problems. You are not afraid to admit when you don\u2019t know something and are proactive in asking for help.
• Ownership & Impact: Your core motivation is to deliver work that truly matters and solves real-world problems. You thrive on taking responsibility for your work from start to finish.
• Collaboration: You enjoy learning from others, sharing ideas contributing to team goals, and being part of a high-performing team.
