  • Understanding of reliability basics (monitoring, logging, alerting) and a practical approach to troubleshooting

  • Awareness of secure engineering fundamentals (least privilege, secrets handling, dependency hygiene) and openness to learning security-by-design

  • Clear written and verbal communication, including creating and maintaining documentation (e.g., runbooks, howtos)

Nice to have 

  • Exposure to AWS services used for data and integration (e.g., S3, Lambda, Step Functions) or a strong desire to learn them

  • Any experience with data processing concepts and tools (SQL, Spark, EMR, streaming)

  • Experience with containers (Docker) and basic runtime concepts
