What you’ll bring
  • Experience building recommendation, ranking, or personalisation systems
  • Strong Python and ML fundamentals (training, evaluation, iteration)
  • Experience shipping models into production environments
  • Familiarity with real-time or event-driven systems
  • Product mindset, you care about impact on user behaviour

Nice to have
  • Experience with LLMs in recommendation or hybrid systems
  • Background in consumer, marketplace, or content platforms
  • Experience with experimentation frameworks (A/B testing, metrics)
  • Familiarity with large-scale data systems

Why it’s interesting
  • Early-stage, high-growth team

  • Direct impact on user engagement and retention
  • Fast iteration loop between model and product
