Salary: £80,000+ per annum
About the Role
This role combines hands-on development with business process analysis, solution viability assessment, and mentoring responsibilities. You’ll act as the bridge between client requirements and technical delivery, engaging directly with stakeholders to capture and document business processes, translating them into viable technical designs, and ensuring successful implementation.
Our client builds AI systems that handle customer-based contact (phone, email, chat, social) so fewer calls need a human, plus AI tools that help council and NHS staff work faster, and back-office automation for routine admin tasks. They wrap all of it under their platform, with a governance layer so organisations can track savings and prove the AI is delivering value rather than just running pilots.

Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
