Commercial Data Scientist

PortSwigger exists to enable the world to secure the web. We build the tools practitioners trust, the knowledge that trains security professionals, and a community that makes anyone who cares about security better — so anyone can make the internet safer. Our products are crafted with care, backed by deep research, and we lead through generous innovation: winning by setting the bar higher and sharing what we create, turning commercial success into wider positive impact.

Our culture didn't happen by accident — it was built deliberately, and it's something we protect with the same care we put into everything we make. We default to trust — brilliant people doing brilliant work, free from micromanagement. We aim for excellence, and we do it with care; performance and compassion go hand in hand. Joy, mastery and purpose belong together here — and if the work stops feeling good, we take that seriously.

The Finance tribe keeps PortSwigger commercially healthy and future-fit. Beyond core accounting, compliance, planning and analysis, we're the guardians of commercial performance and the enablers of strategic investment — providing robust financial controls, accurate reporting and risk stewardship so the business can scale with confidence. We partner closely with Product, Growth and Technology to turn data into clear commercial insight: forecasting and scenario planning that surface opportunities, guide investment in product and people, and give leaders the information they need to make timely, high-quality decisions.

We're looking for a Commercial Data Scientist 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's about investigating difficult business questions, navigating ambiguity, and helping the organisation make better decisions through thoughtful analysis and sound judgement.

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

• 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

Essential

• 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
