Infrastructure Systems Operations Engineer Junior to Mid

🔹What You'll Do - Operate and maintain our Linux, AWS, and blockchain-node infrastructure on a day-to-day basis. - Own routine administration, monitoring, and troubleshooting of services and networking. - Contribute to our infrastructure-as-code work with Terraform, growing your ownership over time. - Support blockchain node operations across our ecosystem. - Automate recurring tasks and diagnostics through scripting. - Help keep our systems secure, patched, and running smoothly. 🔹Requirements Must-Haves: - Linux administration: CLI fluency, systemd, package management, log analysis, and troubleshooting of services and networking. - Shell scripting (Bash) for automation and diagnostics. - Working knowledge of core AWS services: EC2, VPC, IAM, S3, CloudWatch, and load balancers (ELB/ALB). You should be able to operate and debug them, not necessarily architect them. - Terraform at a working level: you have authored and applied configurations and understand state and the plan/apply cycle. Prior Terraform experience on any cloud is fine, it doesn't need to be AWS. - Networking fundamentals: TCP/IP, DNS, SSH, firewalls and security groups. - Git: comfortable with the everyday branch/commit/PR workflow. - Sound credential and access hygiene: proper SSH key handling, least-privilege IAM, keeping secrets out of code and repositories, and keeping systems patched.
