About the Role

You'll take ownership of designing, building, and shipping production-grade systems that power ranking, personalisation, and reward structures in real time. You work hands-on with a small, high-ownership team and have real influence over how infrastructure is built as the team grows.

Responsibilities

  • Design, build, and ship production-grade systems for ranking, personalization, and reward structures.
  • Develop systems that shift user behavior and optimize ranking for user value and business sustainability.
  • Create measurement frameworks to prove system effectiveness.
  • Own end-to-end development of ranking and personalization systems for real-time user reach.
  • Build reward and payout infrastructure balancing user motivation, cost, and business value.
  • Develop behavioral prediction systems using time-series and sequence models.
  • Implement measurement and validation using A/B testing, causal inference, and uplift modeling.
  • Develop and maintain ML infrastructure including pipelines, training loops, serving, and monitoring.
  • Provide technical leadership and mentorship on shipping discipline and impact.

Requirements

  • Shipped production systems end-to-end, from formulation through impact measurement.
  • Full-stack capability: data pipeline to live serving to monitoring and decay.
  • Experience with causal thinking: propensity scoring, instrumental variables, contextual bandits, uplift modeling.
  • Experience building systems handling high-volume behavioral datasets and real-time inference.
  • Published work or equivalent research discipline.
  • Builder's mindset with zero-to-one experience valued.
  • Ability to collaborate cross-functionally with engineering, product, and data science teams on measurement and infrastructure.
