About PortSwigger

PortSwigger is a company built around a simple belief: security should empower people, not slow them down. We create world-class tooling that helps security teams and developers uncover and fix real vulnerabilities, the kind that actually matter. Our products are crafted with care, backed by deep research, and shaped by a relentless drive to make the web safer for everyone.

We’re a successful, engineering-led organisation where small squads are empowered to take forward work in a suitable way, high-leverage work. Curiosity fuels us, craftsmanship defines us, and mutual support keeps us growing together. Here, you’ll have real agency, clear direction, and the freedom to push boundaries, supported by thoughtful coaching and a culture that values learning as much as delivery.

Support Function

The Support function provides the specialist expertise and operational backbone that helps PortSwigger run effectively and scale well. It brings together teams across Culture, Finance, Technology and broader business support roles.
These teams create the conditions for others to do their best work by keeping the business well-supported, well-informed and running smoothly. Whether enabling better decisions, improving day-to-day experiences, or maintaining the systems and foundations we rely on, the Support function plays a vital role in helping PortSwigger operate with clarity, care and resilience.

The Role

We are looking for a strategically minded analytical partner who can operate at the intersection of data, commercial insight, and AI-enabled problem solving.

This role is not about producing dashboards or servicing reporting requests. It is about investigating difficult business questions, navigating ambiguity, and helping the organisation make better strategic decisions through thoughtful analysis and judgement.

You will work across multiple business domains, partnering closely with stakeholders to understand problems deeply, challenge assumptions constructively, and generate insight that influences direction and action.

You will also help shape how analytical work evolves in an AI-first environment — combining human judgement with AI-enabled workflows to improve the quality, speed, and effectiveness of decision-making across the business.

What You’ll Be Doing

• Leading complex analytical investigations across strategic, operational, and commercial topics
• Translating ambiguous business questions into structured analytical approaches
• Combining multiple data sources to identify patterns, risks, and opportunities
• Producing clear recommendations that influence senior stakeholders and decision-making
• Partnering cross-functionally across technical and non-technical teams
• Evaluating AI-assisted analytical outputs critically and pragmatically
• Helping improve how analytical work is performed across the organisation
• Building frameworks, approaches, and systems that create long-term organisational value
• Surfacing uncertainty, trade-offs, and assumptions transparently
• Contributing to a culture of intellectual curiosity, rigour, and continuous learning

What We’re Looking ForEssential

• Strong analytical and strategic reasoning capability
• Experience solving commercially meaningful problems in ambiguous environments
• Ability to communicate complex concepts clearly to non-technical audiences
• Strong judgement around data quality, uncertainty, and decision-making
• Experience working with AI-enabled analytical workflows or strong curiosity to develop in this space
• Comfortable operating autonomously while collaborating effectively across teams
• Strong stakeholder management and relationship-building capability
• High intellectual curiosity and growth mindset
• Evidence of influencing strategic decisions through analysis and insight

Desirable

• Experience operating in scaling or transforming businesses
• SQL and/or Python capability
• Experience evaluating AI-generated analytical outputs critically
• Experience improving analytical capability or decision-making systems within organisations
• Exposure to commercial strategy, operations, product, or finance environments

How We Work

We value people who:

• Ask thoughtful questions before jumping to solutions
• Work collaboratively and challenge constructively
• Are comfortable operating with ambiguity
• Care deeply about quality and impact
• Share context openly and elevate those around them
• Pursue learning continuously
• Balance rigour with pragmatism
• Take ownership and follow through reliably

This role is suited to someone who wants to shape decisions, improve systems, and help define what high-quality AI-enabled analytical work looks like in practice.

At PortSwigger, we believe people should be paid what they’re truly worth — not just what we could get away with or what the market dictates. That’s why we pay generously above normal market levels, based on each person’s individual skills and contribution.

Our approach works: 95% of Swiggers say they’re mostly or completely satisfied with their pay and benefits.

Alongside a strong base salary, we offer share options and a comprehensive benefits package designed to support both your work and life.
