Infrastructure System Engineer

We're looking for a junior-to-mid systems and infrastructure engineer to take on the day-to-dayoperation of our Linux, AWS, and blockchain-node infrastructure. You'll start by owning routineadministration and monitoring, and grow into more of our infrastructure-as-code andnode-operations work over time. This is a hands-on operations role with a clear path to broaderresponsibility, and a great fit for someone with solid fundamentals who wants to deepen theircloud and infrastructure skills in a real production environment.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.Cool-to-Haves:Terraform beyond the basics: modules, remote state, multi-environment setups.Blockchain node experience, whether with Cosmos specifically or another chain.Docker; Kubernetes exposure is a plus.Monitoring and observability tools (Prometheus, Grafana).Python for tooling beyond Bash.CI/CD exposure.Soft SkillsAccountability: you own your work and communicate openly when something goes wrong, focusing on fixing it rather than explaining it away.Honesty and candor: you speak up for what's good for the team, even when it's not the easiest thing to say.A self-taught instinct: you're comfortable figuring things out on your own and genuinely enjoy learning, since much of this role is grown into rather than known on day one.Collaborative team player, self-directed and comfortable working autonomously in remote environments.
