About the role

Key responsibilities & impact
  • Lead Through Execution: Drive major technical initiatives from design through production, improving scalability, reliability, and correctness across critical systems.
  • Build Distributed Systems: Design and evolve backend services, APIs, event-driven workflows, and data models that support complex business processes at scale.
  • Own Critical Platform Infrastructure: Improve the operational foundations of the platform through better observability, testing, deployment safety, and incident reduction.
  • Solve Complex Workflow Problems: Design systems that handle long-running workflows, asynchronous processing, consistency guarantees, and failure recovery in high-stakes environments.
  • Work Across Teams: Lead initiatives spanning engineering, product, data, commercial, and machine learning teams - aligning stakeholders and unblocking delivery.
  • Productionise Machine Learning: Collaborate with ML and data teams to safely integrate forecasting, optimisation, and pricing models into production systems.
  • Raise Engineering Standards: Mentor senior engineers, influence architectural direction, and improve engineering practices across the organisation.
  • Design for Scale: Anticipate scaling challenges before they emerge - improving throughput, resilience, and platform evolution as the business grows.
