We are looking for a focused Middle or Senior DevOps Engineer to join our team. We are currently managing a dual infrastructure environment that includes both microservices and modular monolith architectures.

• Observability & Monitoring:
  • Lead the transition and setup of our monitoring stack using BetterStack.
  • Configure alerts and health checks to maintain high visibility into the health of both architectures.
  • Regularly review of monitoring tickets as well as escalate of outstanding issues to development team.
