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 new capabilities into real improvements for users and the team.

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 ship robust, user-ready features that deliver measurable impact. More importantly, you’ll be trusted to think boldly, learn fast, share your work early, and make great decisions in service of our users.

What You’ll Do
  • Solve complex technical problems with creativity and sound judgment
  • Contribute across the stack (frontend, backend, infrastructure), 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 and AI
  • 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
  • Help shape how the team works — its practices, its rhythms, and its culture. You're not just inheriting a playbook, you're contributing to it

Requirements

About You

We're looking for engineers who care more about outcomes than output — and who understand that the best work happens when a well-matched team is pulling in the same direction. The individual skills matter. So does how you bring others with you.

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

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’re curious about how to apply AI to improve developer experience, user value, or product outcomes
  • You have, in your work or personal time, used and adopted modern AI tools (e.g. LLMs, copilots), treating them as agentic coding partners—knowing when to trust, adapt, or override their outputs to build high-quality solutions

Ready to Apply?

We care more about mindset and potential than perfect CVs. If you’re excited by the idea of product-focused engineering and a high-trust, high-autonomy culture, we want to hear from you.

Not sure if you're the right fit? Apply anyway. You might be exactly who we're looking for. Working Policy

At PortSwigger, we're an office-first company because we believe the best work happens when we're together. Being in the same physical space makes it easier to collaborate, solve problems quickly, learn from one another, and build the kind of relationships that make teams genuinely effective. It creates the conditions for spontaneous conversations and natural knowledge sharing that are hard to replicate any other way.

Our offices are designed with this in mind — spaces where information flows freely and cross-team connections happen without effort. That's not accidental. Being office-first is a deliberate choice, rooted in what we've found actually works — for the quality of our output, and for how we grow as people.

Company Benefits

  • We believe in rewarding people generously and offer a competitive salary based on individual skills and contribution.
  • We offer share options
  • 8% employer pension contribution
  • Life assurance
  • Income protection
  • Private medical insurance
  • 25 days holiday (plus public holidays)
  • We host regular team events and have fantastic summer and winter parties.
  • We foster an inclusive and high-performance culture with a focus on work-life balance.
  • You’ll be part of a humble, supportive, and fun team that values collaboration, humour, and a strong sense of belonging.
  • Our working hours are flexible, with core hours from 9am to 4pm.

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Starling is the UK’s first and leading digital bank on a mission to fix banking! We built a new kind of bank because we knew technology had the power to help people save, spend and manage their money in a new and transformative way.

We’re a fully licensed UK bank with the culture and spirit of a fast-moving, disruptive tech company. We’re a bank, but better: fairer, easier to use and designed to demystify money for everyone. We employ more than 3,000 people across our London, Southampton, Cardiff and Manchester offices.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

Our Data teams are excited about the value of data within the business, powers our product decisions to improve things for our customers and enhance effective and agile decision making, regardless of what their primary tech stack may be. Hear from the team in our latest blogs or our case studies with Women in Tech.

We are looking for talented data professionals at all levels to join the team. We value people being engaged and caring about customers, caring about the code they write and the contribution they make to Starling. People with a broad ability to apply themselves to a multitude of problems and challenges, who can work across teams do great things here at Starling, to continue changing banking for good.

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
  • Believe in clean coding, simple solutions, automated testing and continuous deployment.
  • Like to take ownership of a feature from the original idea through to live.
  • Think (like us) that a small number of empowered developers is the right way to deliver software.

Company Benefits

  • 33 days holiday (including flexible bank holidays)
  • An extra day’s holiday for your birthday
  • 16 hours paid volunteering time a year
  • Part-time and/or flexible hours available for most roles
  • Salary sacrifice, company enhanced pension scheme
  • Life insurance at 4x your salary
  • Hybrid/remote working
  • Private Medical Insurance with VitalityHealth including mental health support and cancer care. Partner benefits include discounts with Waitrose, Mr&Mrs Smith and Peloton
  • Generous family-friendly policies
  • Varied social groups set up and run by our employees
  • Perkbox membership giving access to retail discounts, a wellness platform for physical and mental health, and weekly free and boosted perks
  • Access to initiatives like Cycle to Work, Salary Sacrificed Gym partnerships and Electric Vehicle (EV) leasing

Full details are available on our careers site

Interview Process

Interviewing is a two way process and we want you to have the time and opportunity to get to know us, as much as we are getting to know you! Our interviews are conversational and we want to get the best from you, so come with questions and be curious. In general you can expect the below, following a chat with one of our Talent Team:

  • Stage 1 - 30 mins with one of the team
  • Stage 2 - Take home challenge
  • Stage 3 - 90 mins technical interview with two team members
  • Stage 3 - 45 min final with an executive and a member of the people team
