An opportunity to join a high performing technical team with an exceptional track record for delivering innovative software products, original technical research, and world-leading educational output.


Based in Knutsford, Cheshire, PortSwigger Web Security is a global leader in application security testing (AST). Our cutting-edge software is used by over 17,000 customers in 130 countries to help them secure their web applications. Our success has been recognized through various awards, including the Sunday Times Tech Track and Export Track, the UK Private Business Awards, and the Queen's Award for Enterprise.

We have recently expanded our range of products and services, with a corresponding growth in the volume of our technical written output. We are now looking for a technical writer to join our team and help us deliver outstanding written content to support our products and services.

About you

You are a natural communicator, good with words, and love writing.

You have a personal interest in technology, and a flair for communicating technical messages to different audiences.

You're a natural team player, but you're willing to work autonomously. You're excited about the prospect of building a new capability and a high-performing team from scratch.

You're ambitious and driven. You set exceptionally high standards in everything that you do. You set demanding goals and are always looking beyond them for your next opportunity to learn and excel.

You have a strong academic record, with a core element of written or other creative output. You've worked as a technical writer for several years but are still primarily a "doer" and not a manager.

You're ready for a new challenge and relish the opportunity to help an already successful business to achieve even more.

Essential skills

Key responsibilities

The core of the role will involve creating and updating technical written content in three areas:

In addition to the generation of written content, the role will involve producing scripts for technical presenter-led videos and liaising with graphic designers to devise infographics to illustrate written content.

Be well rewarded

We firmly believe in paying people what they're worth to us, not just what we can get away with or what they could earn elsewhere. We pay excellent salaries above the normal market level, and this is always determined based on your individual skills and contribution.

In addition to a generous base salary, we offer share options and a comprehensive benefits package.
