  • Strong skills in Python, Bash, or comparable scripting languages for automation.
  • Hands-on experience with observability stacks (e.g., New Relic, Grafana, CloudWatch, Datadog) and incident response.
  • Familiarity with microservices architectures and patterns for resilience/scalability (e.g., throttling, retries, circuit breakers).
  • Experience with common data stores (MySQL/RDS, DocumentDB, Elasticsearch, Redis).
  • Working knowledge of backends (bonus: performance optimization and monitoring); experience with Java, Python, or Go is a plus.
  • Interest or experience in applying AI for infrastructure automation, monitoring, or optimization (a strong plus).
  • A collaborative mindset with strong communication skills, able to work independently and comfortably across teams and disciplines.

  • Thrives in a fast-paced, high-growth environment and ready to tackle complex system challenges at scale.
