About the role

Key responsibilities & impact

Support and operate our Linux/UNIX systems, VMware infrastructure, CI/CD pipelines, MySQL databases, and containerized workloads that serve our retail clients 24×7.
Own incidents end-to-end: triage alerts, drive root-cause analysis across the application, database, and network layers, and write the post-incident docs that stop recurrence.
Tune and operate MySQL at production scale: query analysis, replication topology, backup and recovery, and schema changes against live workloads.
Containerize and template services using Docker and infrastructure-as-code patterns to make deployments repeatable, declarative, and boring.
Improve observability across the fleet — metrics, logs, traces, and dashboards — so problems are seen before customers feel them.
Use modern AI-augmented engineering tools (Claude Code, MCP-based workflows, agentic automation) as a daily multiplier — to operate faster and extend what one engineer can deliver.
Document and mentor. Runbooks, design docs, and onboarding material aren't an afterthought here — they're how the team scales.

Requirements

What you’ll need

5+ years operating production Linux/UNIX (RHEL, CentOS/Rocky, Debian/Ubuntu) at meaningful scale.
Strong MySQL operational experience — replication, performance tuning, backups, recovery, and schema migrations.
Hands-on VMware/vSphere experience in production environments.
Java application-tier troubleshooting experience — comfortable reading thread dumps, GC logs, and heap behavior.
Solid DevOps fundamentals: Git, CI/CD pipelines, Ansible (or similar configuration management), Terraform (or similar IaC), and Docker.
Networking literacy: TCP/IP, DNS, TLS, HTTP/S, load balancing, basic firewalling. You can read a tcpdump and a cert chain.
Comfortable scripting in Bash. Python is not required, but you should have a working understanding of programming fundamentals and be able to read, modify, and write straightforward code.
Strong troubleshooting instincts and the temperament lead under pressure.
Real day-to-day experience using AI-augmented engineering tools (Claude, Cursor, Copilot, MCP servers, agentic workflows) — not just demos.
Experience with Datadog or comparable observability platforms.
