Alongside the technical work, the role involves working with enterprise clients to scope technical requirements, define success criteria and support product delivery, translating client needs into practical technical solutions and communicating architectural decisions clearly. The engineer will also monitor deployed AI agents, evaluate their performance and report on business value and outcomes, mentor junior implementation engineers and contribute to best practices across the engineering team, and collaborate with internal teams to feed client insights and technical learnings back into product development. The advert also highlights working across APIs, system architecture, orchestration and cloud infrastructure, and demonstrating the impact of deployed AI agents.
