• Strong foundation in computer science principles and engineering fundamentals
• Proficient in development, particularly in Go (preferred) or Python, with experience building automation tools and software for large-scale, distributed systems
• Hands-on experience with observability tooling such as DataDog, Prometheus, Mimir, Elasticsearch, Grafana, Jaeger, and tracing systems
• Expertise in cloud platforms like AWS, GCP, or Azure, with experience managing cloud infrastructure using Kubernetes and containers (Docker)
• Deep knowledge of building and maintaining reliable, high-performance, and scalable distributed systems
• Solid understanding of SRE principles, incident response, and designing fault-tolerant architectures
• Experience with infrastructure-as-code tools like Terraform or Ansible for managing cloud environments
• Familiarity with CI/CD pipelines, automated testing, and continuous delivery practices
• Strong analytical and problem-solving skills, with experience troubleshooting complex distributed systems
• Excellent communication and collaboration skills, with the ability to work cross-functionally to enhance platform observability and reliability
• Experience working directly with development teams, with a willingness to dive into application code for observability-related topics, even when unfamiliar with the application code
• Solid experience with Docker and Kubernetes, coupled with a strong foundation in Unix systems and networking concepts
• Open to feedback, recognizing that no one is perfect—including us. We see feedback as an opportunity to learn and grow together
