More:
We are partnering directly with Opencast Software to hire contractors in software development at senior level or technical lead level. We care more about engineering craft, clean design and thoughtful problem-solving than speed of ticket delivery. Our consultants work in complex environments, pairing often and applying TDD, emerging design and refactoring to leave code better than they found it. We are collaborative, tech agnostic and focused on simple, robust solutions. The role is varied and technical, with regular on-site attendance across our HQ, hub offices, client sites and home. The salary is £450 - £600 per day inside IR35. Interviews are conducted via Microsoft Teams, and we welcome candidates from all identities, attributes, ways of thinking and backgrounds.
