Hybrid: Two days in our client's London office and three days working from home. On Monday morning, you might be refining an API connection between a collections database and a public-facing platform. By Wednesday, you could be writing a PHP 8.2 script to automate image processing for a new exhibition launch. Friday afternoon? Testing out an AI tool to help curators search archive materials faster. That’s the reality of life as a Backend Integration Developer here. No two weeks look the same. The mix of backend software development, systems integration, and cloud infrastructure work means you’ll constantly be learning, solving problems, and collaborating with colleagues from across the organisation. This is a fantastic opportunity for a technically adaptable developer to join a nationally respected cultural institution with an ambitious digital vision.
