OZmap is a SaaS platform that provides GIS-based mapping and management for fiber-optic (FTTH) and hybrid network infrastructures, tailored for internet service providers (ISPs). It centralizes georeferenced network documentation, planning, monitoring (including OTDR and switch integration), mobile field apps, and open APIs to streamline provisioning, reduce operational costs, and speed repairs. OZmap also offers data migration, integrations with CRMs/ERPs, dashboards, and tools for commercial viability checks to support network growth, M&A and day-to-day operations.

📋 Description

• Design, operate and evolve AWS (EC2) and on-premises environments with containers (Docker), ensuring availability, security and scalability; • Operate and administer Linux production environments (systemd, kernel/network tuning, I/O, process troubleshooting); • Build and evolve CI/CD pipelines from scratch, including quality and security gates; • Develop end-to-end observability (instrumentation, exporters, PromQL, SLI/SLO, alerts); • Lead advanced troubleshooting, root cause analysis and blameless post-mortems — driving structural change afterwards, not just producing a report; • Implement automation using Infrastructure as Code; • Analyze and optimize cloud costs: rightsizing, usage analysis and proposing data-driven alternatives; • Act as a technical reference for developers and engineers, influencing architecture without relying on formal authority.

🎯 Requirements

• Required: production experience operating core primitives in AWS (~4+ years): EC2, VPC/networking, IAM and security — production operation and technical decision-making; • Linux and networking (~4+ years): server administration and production troubleshooting — disk full, OOM killer, network diagnostics; processes, memory and I/O; • CI/CD built from scratch (~3+ years): pipelines created and evolved by you (GitHub Actions, Jenkins, self-hosted runners, secrets, caching, gates); • End-to-end open-source observability (~2+ years): Prometheus, Grafana, Loki, VictoriaMetrics or equivalents — configured and operated by you, not just used. OpenTelemetry — including instrumentation, exporters, PromQL and SLI/SLO definition; • Operation under managed layers: concrete experience with nginx/HAProxy/Envoy, Linux underneath, and leading the resolution of critical incidents you have driven; • Docker in production (~3+ years): real operation of containers in critical environments — volumes, networking, resource management, graceful shutdown of services; • High autonomy: receives an ambiguous problem ("our observability is weak") and delivers end-to-end; • Ownership and proactivity: anticipates problems before they become incidents; • Clear communication and technical influence, connecting development, infrastructure and business teams; • Conducts post-mortems focused on root cause, organizational learning and continuous improvement, without a blame culture; • Maturity to self-manage while working remotely.
