Prophet builds digital clones of organisations — AI-powered, mathematical models that bring together thousands of marketing, commercial, and macroeconomic data points. These models let leaders test strategies, run "what if" scenarios, and make confident decisions before committing real-world budgets. We're a fast-growing scale-up on a mission to make marketing intelligence radically simpler and more actionable. Our platform helps brands bring together online, offline, and macro data to understand what's really driving performance — and what to do next.

We're hiring a Senior Data Scientist to play a critical role in delivering MMM and marketing effectiveness models our customers rely on for real decisions. This is a senior, hands-on role for someone who owns outcomes, moves fast, and gets satisfaction from shipping work that actually gets used.

What you'll be doing

As a Senior Data Scientist at Prophet, you'll sit at the intersection of customer impact, modelling, and production delivery. You'll own marketing measurement work end-to-end — from raw data through to live models — and work directly with customers to ensure what you build is trusted, understood, and used. You are not here to support someone else's roadmap. You are here to own the solution.

You will:

• Build and ship MMMs used for real decisions - Take customers from messy, incomplete data to production-ready MMMs that inform planning, forecasting, and optimisation.
• Own customer delivery end-to-end - Run customer projects independently — scoping problems, making trade-offs, hitting deadlines, and getting models live without babysitting.
• Translate business questions into models - Work directly with technical and non-technical stakeholders to turn commercial questions into robust modelling approaches — and explain results clearly.
• Partner with Platform & Engineering - Collaborate closely to productionise models, improve automation, and design solutions that scale beyond one-off projects.
• Continuously improve how we deliver - Standardise approaches, reuse patterns, and automate repetitive work to increase reliability and team velocity.

You'll thrive in this role if you…

• See yourself as an operator first
• Enjoy turning messy data into something useful and reliable
• Are comfortable making pragmatic calls with imperfect information
• Are customer obsessed - and take personal responsibility for customer outcomes
• Prefer shipping and improving over endless iteration
• Enjoy working in a scale-up where ambiguity is normal and ownership is high

What you bring (non-negotiable)

• Deep, hands-on experience in MMM / marketing effectiveness
• Proven experience shipping MMMs into production that were used for real decisions
• Strong Bayesian / probabilistic modelling foundation
• Comfortable owning the full lifecycle: data → model → deployment → monitoring
• Ability to independently run customer projects end-to-end
• Strong customer lens and commercial mindset

What will make you especially successful at Prophet

• Clean, production-grade Python (not notebook-only); PyMC preferred
• Comfort working with messy, incomplete, real-world customer data
• Experience standardising or templatising modelling approaches
• Familiarity with modern data stacks (GCP, DuckDB, orchestration, etc.)
• Startup or consulting experience where speed mattered
• Experience mentoring others or lifting team standards
• Uses modern AI tools (Cursor, Claude, etc.) to move faster without cutting corners

• Innovation Leadership: Represent breakthrough technology powered by Nobel Prize-winning mathematics
• Strategic Role: Shape the roadmap of a product that top agencies and brands rely on
• Office first culture - Built on trust, creativity, and speed
