Who are 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.
Finance Tribe:
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.
