About us: Fospha is dedicated to building the world's most powerful measurement solution for online retail. For over a decade, we've helped teams make smarter decisions with full-funnel marketing insights, forecasting, and optimisation. With Fospha, every team moves faster and grows smarter. Trusted by leading brands across three continents, including Huel, Oh Polly, and Represent, Fospha manages $4 billion in annual ad spend. We're scaling fast across London, Mumbai, and Austin – and we're now looking for two Marketing Science Leads to join our Customer Success team to support the growth of the business from all things measurement!
The Role: Fospha is pioneering the future of marketing intelligence, moving enterprise retailers beyond the broken world of click-based attribution. Our mission is to transform complex data into the single, most trusted source of truth for CMOs and CFOs managing high-stakes budgets. As a Marketing Science Lead, your focus will be acting as the technical authority for our Enterprise tier, serving as a dedicated conduit between our Customers, Customer Teams, Data Science, and Product teams. We are looking for a rigorous, analytical practitioner ready to operationalize advanced modelling into tangible business decisions, driving sustainable growth for clients like Huel, Dyson, and Gymshark. You will operate as a post-sales, value-delivery engine embedded directly within the Customer Success department.
Key Responsibilities
- Client-Facing Support: Proactively and reactively support Customer Success and Account Management teams on model trust and methodology escalations, directly combating objections related to competitors like Triple Whale or Northbeam.
- Incrementality & Learning Agendas: Act as the primary Marketing Science Strategist, designing first-party incrementality tests, calibrating models, and building structured learning agendas for clients.
- R&D "Mouthpiece": Systematically capture and triage field feedback and methodological objections, feeding structured intelligence back to our Product and Data Science teams.
- Collateral & Knowledge Creation: Build the definitive technical collateral, Academy content, and internal training to raise the baseline data literacy of our entire Go-To-Market organization.
What are we looking for?
- Marketing Science Experience: 3-5 years of experience in marketing science, data analytics, or technical account management.
- Measurement & AdTech Knowledge: Deep understanding of Media Mix Modeling (MMM), Multi-Touch Attribution (MTA), incrementality testing, and the broader AdTech ecosystem, including Meta, Google, and TikTok.
- Commercial Translation: The rare ability to translate complex data science and Bayesian models into highly digestible commercial insights for non-technical executives.
- Communication Skills: Excellent verbal and written communication skills. Ability to articulate complex concepts clearly and persuasively to diverse audiences. Proven track record of working effectively in cross-functional teams. Ability to build consensus and drive alignment across diverse stakeholders.
- Problem-Solving Skills: Strong problem-solving abilities with a proactive approach to identifying and addressing challenges. Ability to navigate ambiguity and make sound decisions under pressure.
Our Values and Principles
- Seek inclusion & diversity: We create an environment where everyone feels welcome, and people are encouraged to speak and be heard.
- Work Hard, Work Well, Work Together: We take responsibility for making things happen, independently and together; we help colleagues in need and close loops, making sure our work is complete and has lasting impact.
- Grow: We are proactive, curious and unafraid of failure.
- Customer at the heart: We care about the customer, feel their pain and love building product that solves their biggest problems.
- Candour with caring: We deliver candid feedback with kindness and receive it with gratitude.
Above all, our people show a willingness to work together and get their hands dirty to deliver product success, which means our customers are successful!
