DevOps / Infrastructure Engineer

Role Overview

We're looking for a DevOps Engineer to own the infrastructure that keeps WatchMen running reliably — from AWS cloud services down to a distributed fleet of edge devices sitting on factory floors. This is a hands-on role across cloud infra, CI/CD, monitoring, and self-hosted services, not a ticket-queue ops job.

Responsibilities

• Managing AWS infrastructure via Terraform, ECS on EC2, ALB, networking, and dedicated-tenant VPC architecture
• Operating our Docker Swarm–based backend deployment and improving its reliability and scaling
• Maintaining our data infrastructure: PostgreSQL, TimescaleDB, PgBouncer, and Redpanda/Kafka event pipelines
• Building and maintaining CI/CD pipelines on self-hosted GitLab CE
• Owning observability: Grafana Cloud dashboards, OpenTelemetry tracing, and alerting for both cloud services and production incidents
• Managing Grafana Alloy fleet monitoring across our Raspberry Pi/edge device fleet deployed at customer sites
• Maintaining self-hosted internal services (MQTT broker/EMQX, Vaultwarden, n8n) behind Caddy reverse proxies
• Diagnosing infrastructure-level production issues, network, database, message broker, and container orchestration problems
• Hardening system security, including tools like Wazuh

Requirements

• 3–6 years of professional DevOps/infrastructure experience
• Strong hands-on experience with Docker and container orchestration (Docker Swarm, ECS, or Kubernetes)
• Experience with Terraform or another infrastructure-as-code tool
• Solid Linux systems administration and networking fundamentals
• Experience with CI/CD pipelines (GitLab CI, GitHub Actions, or similar)
• Comfortable debugging production incidents independently

Skills

• AWS
• Terraform
• Docker
• GitLab
• Linux
