As a Senior Software Engineer / Web Developer, you’ll join one of Twinkl’s web development teams with a primary focus on one of the following areas:

  • Smaller project/feature work, site reliability engineering and codebase modernisation,
  • Developing and supporting specific EdTech web applications & tooling, or

There is significant scope for flexibility and variety across our teams/roles plus common shared responsibilities and expectations - we appreciate “one size may not fit all” and we can discuss these roles and your particular passion, experience and professional goals at interview to find a great fit, then regularly review this as you grow.


We are looking for team members who are excited and passionate about Twinkl’s values and education/EdTech as a whole. You’ll have a can-do attitude and be capable of working autonomously as an individual or as part of a team, using agile values, principles and practices.

You’ll possess the skills and experience typical of someone who has recently spent at least ~four years implementing real-world solutions using: HTML, CSS, Javascript, PHP (OO MVC) and MySQL (or other relational DB). You are confident you can hit the ground running with these technologies and are proficient with version control/deployment processes and software (Git).
