PHP Developer

Due to increasing workloads, we're looking for a PHP developer to help us build a variety of exciting products. Working with our existing team of developers and designers, you'll be involved in building websites, workflow tools and educational products for a range of commercial and government clients.

Helical Levity is led by world renowned cyber security expert James Lyne and combines a team of world-class security researchers, designers and developers. Together we provide expert cyber security consultancy and build industry leading tools that, amongst other things, help to identify and develop new talent.

The work itself will involve working on and improving existing PHP apps as well as new products which you'll need to help build from scratch. We're looking for someone who is insatiably curious and is passionate about perfecting their skills, as well as learning new ones. You are someone who will speak up; get involved in debates and quickly inform others if you need help or think something is wrong. You are comfortable writing clean, tested and maintainable code. You'll need to have a strong working knowledge of PHP, MYSQL, JavaScript and Git.

Much of the team work remotely but we do have an office in Stow-on-the-wold, Gloucestershire. There is the option to work in either environment but we do tend to meet up in Oxford or London to catch up on projects so being within a sensible travel distance of either would be useful.

If you have a passion for PHP and want to put your programming skills toward tackling some fun and difficult coding challenges, please do get in touch.
