Senior SDR

Why this role exists

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.

The Growth Tribe

The Growth Tribe exists to help PortSwigger reach the people who need our tools most and ensure they get real value from them.
