We are looking for someone with a strong leadership mindset: someone who can take ownership of ambiguous problems, guide a small team, make pragmatic technical decisions, and turn early ideas into working prototypes. You will work in a fast-moving research environment where problems are often under-specified. You should be excited by ambiguity, when the goal is defined but the path is still unexplored. You should know how to explore, prototype, evaluate, and decide when something is “good enough” to move forward. You will collaborate closely with engineers, product leaders, researchers, and business stakeholders. This requires not only strong technical depth in AI, but also clear communication and the ability to adapt your message depending on the audience. As part of the AI team at Nexthink, you will: Lead the design and development of AI agents and features, from vague problem definition to production deployment impacting millions of users. Drive rapid prototyping and experimentation to validate ideas and unlock new opportunities. Help guide the team’s technical direction, priorities, and execution of rhythm. Make fast, pragmatic decisions when trade-offs are unclear. Support and mentor engineers while keeping the team focused on outcomes. Maintain a strong sense of what matters: customer value, technical feasibility, speed of learning, and long-term product potential. Explore new AI technologies, tools, models, and agentic patterns with curiosity and critical judgment.
