About the role

  • Design and build core AI and data systems that support decision-making across the platform
  • Work with complex, imperfect, and evolving data from multiple internal and external sources
  • Develop models and signals that balance accuracy, uncertainty, and explainability
  • Help define how intelligence is represented, updated, and acted upon inside the product
  • Decide when to use ML, statistical methods, rules, or hybrids, and why
  • Partner closely with product and engineering so AI is embedded in workflows, not bolted on
  • Establish standards for evaluation, monitoring, and iteration in production
  • Use modern AI tooling, including LLMs where appropriate, with a bias toward leverage over novelty
  • Collaborate with regulatory and compliance teams to ensure outputs are defensible and robust
  • Move fast without being reckless, understanding the cost of false confidence

Requirements

  • Strong grounding in statistics, probability, and applied machine learning
  • Proven experience shipping AI or ML systems into production
  • Experience working with non-ideal data where ground truth is partial, delayed, or noisy
  • Comfort making trade-offs between precision, recall, confidence, and coverage
  • Ability to reason about uncertainty and error, not just point predictions
  • Clear communicator who can explain complex ideas to non-technical stakeholders
  • Strong experience with Python and modern ML tooling
  • Practical experience working with LLMs or advanced AI systems in real applications
  • Bias toward building decision-support systems, not opaque black boxes
  • High intellectual honesty and strong technical judgment
Benefits
  • Excellent Salary: Competitive and reflective of the responsibilities of a founding role
  • Equity Options: Meaningful ownership in a long-term company
  • Hybrid Work: At least 3 days in our London or Dublin office
  • Extended Remote Work on Request: Outcomes matter more than optics
  • Builders, Not Tourists: Work with people who care deeply about getting things right
