Head of Customer Success
Sales & Business Development, Customer Service
United Kingdom
Posted on Jul 3, 2026
Codility helps the world’s best companies hire the right engineers quickly, fairly, and with confidence. We invented the technical assessments category and continue to lead it through constant product innovation, deep customer focus, and a strong understanding of how engineering teams hire.
As AI changes how software is written, reviewed, and evaluated, Codility is helping customers rethink what great technical hiring looks like. We are also building Codility as an AI-native company, where teams are expected to use AI thoughtfully to improve how we work, support customers, analyse data, scale expertise, and build better products and processes.
Your role
As Head of CS, you will own key customer relationships while also helping bring structure, consistency and focus to our Customer Success function.
This is a player-coach role. You will manage a portfolio of strategic customers, lead post-sales activities that drive adoption, retention and expansion, and help the wider team improve how we run Customer Success at Codility.
You will be expected to bring strong customer judgment, commercial discipline, technical credibility and a practical, structured approach to account management. We are looking for someone who can be credible with senior Talent, People and Engineering stakeholders, and who can help our team better support customers as they rethink technical hiring in an AI-enabled world.
