Role Description This is a rare opportunity to build a new capability from the ground up. You will work on high-visibility problems that sit at the intersection of data science, strategy, business performance, and AI transformation. You will partner directly with leadership, shape how the company measures itself, and build the operating intelligence that helps Busuu make better decisions, faster. - Build a new organisational intelligence capability in a company actively reshaping itself around AI. - Work on problems with direct visibility to the General Manager, leadership team, and cross-functional heads. - Design cutting-edge measurement systems, decision frameworks, and intelligence layers — not just dashboards. - Operate across B2C, B2B, Product, Commercial, and AI initiatives, with broad influence on how the company runs. - Combine deep analytical thinking with real business impact in a role that is strategic, hands-on, and highly visible. We are hiring a Staff Data Scientist to lead Organisational Intelligence within Decision Intelligence. The mission of this role is to help Busuu understand itself as a system: how performance is evolving, where transformation is working or failing, how teams should interpret signals across the business, and what leadership should do next. - Design the measurement architecture, synthesis, and business learning loops that connect data to decisions at company level. - Own the analytical foundation behind monthly and quarterly business reviews. - Define how transformation is measured, establish trusted business metric definitions, and help turn AI governance into an operating reality. Qualifications - 8+ years of experience in data science, analytics, business intelligence, strategy, consulting, or a similar function in a scaled digital, SaaS, consumer tech, subscription, or EdTech business. - Strong experience translating analysis into business decisions, preferably with exposure to executive or leadership-level reporting. - Experience designing performance frameworks, KPI systems, company scorecards, business review processes, or equivalent decision-support systems. - Strong SQL skills and confidence working directly with complex datasets. - Ability to move fluidly between hands-on analytical work and high-level executive communication. - Experience influencing senior stakeholders across functions such as Product, Finance, Commercial, Marketing, Operations, Engineering, or Data. - Strong commercial judgment, including understanding of metrics such as bookings, retention, NRR, funnel performance, LTV:CAC, and unit economics. Requirements - Experience across both B2C subscription and B2B SaaS environments. - Experience in AI, transformation, operating model change, or measurement of organisational effectiveness. - Experience defining semantic logic, metric governance, or business logic in partnership with analytics engineering or data engineering teams. - Experience contributing to board-level, leadership-level, or annual operating narratives. - Python or similar analytical tooling for data exploration, prototyping, and scalable analysis. Benefits - Significant autonomy and broad exposure. - Opportunity to shape a capability that matters to the future of Busuu.
