About the role

  • Collaborate with a lead engineer to design and develop high-performance, API-based backend services that meet service-level objectives (SLOs) and scale to support growing business needs.
  • Own the health and uptime of business-critical systems you and your team build.
  • Participate in on-call rotations to quickly resolve incidents and conduct postmortems to drive continuous improvement in system reliability.
  • Partner with product managers, engineering teams, and infrastructure teams to define technical requirements and design scalable, maintainable systems that align with business goals and product roadmaps.
  • Champion and implement continuous integration/continuous deployment (CI/CD) pipelines, automated testing, and security practices throughout the development lifecycle to ensure the reliability and security of production systems.
  • Ensure comprehensive documentation of API designs, system architectures, and operational procedures to enable internal teams and external customers to easily build and integrate with the APIs in a self-service manner.

Requirements

  • Proven experience designing and implementing observability solutions (e.g., DataDog) to ensure system reliability, performance, and uptime in production
  • Familiarity with DevSecOps practices, including implementing CI/CD pipelines, automated testing, and integrating security throughout the development lifecycle
