About the role

  • Develop and enhance our customer-facing APIs focusing on performance, reliability, and an intuitive user experience.
  • Design, build, and maintain our near real-time alerting platform, from data processing and anomaly detection to reliable notification delivery.
  • Optimise the performance of complex analytical queries that power our APIs and dashboards, working closely with the database platform team.
  • Create intuitive and powerful tools that allow customers to explore their data and configure meaningful alerts based on logs and metrics.
  • Scale our API and alerting infrastructure to support a growing number of internal and external use cases.
  • Collaborate with front-end engineers and product managers to define API contracts and deliver a seamless data experience for our users.
  • Ensure the operational health of our APIs and alerting systems by developing comprehensive monitoring, and participating in an on-call rotation (with the flexibility to be on-call outside of standard working hours as needed).
