Why Operations Engineers Are Anything But Low‑Skill: A Deep Dive into Their Real Technical Challenges

Background

The author, an automation operations engineer, explains that after leaving a company many of his automation scripts were abandoned because developers and testers lacked the skills to maintain them, forcing the business back to manual processes and increasing personnel costs.

Common Misconceptions

Developers often view operations as "low" because they assume it only involves managing machines or databases, but the reality is far more complex and technically demanding.

Key Capabilities

1. Monitoring Ability

Ops engineers must monitor Linux services, network, disk, CPU, and memory comprehensively. They use a variety of tools such as route, iptables, tcptop, biotop, biosnoop, mdflush, and others, packaging the data into scripts that report to cloud platforms for full‑stack visibility.

2. Deep Linux Knowledge

Experienced ops staff can debug the Linux boot process step‑by‑step, treat the kernel like a program they can single‑step, and resolve obscure issues such as environment‑variable changes not taking effect due to missing kernel hooks.

3. Firefighting Ability

When applications cause resource exhaustion—e.g., high connection counts, disk I/O bottlenecks, or CPU spikes—ops engineers diagnose the root cause, differentiate between application‑level problems and mis‑allocated resources, and guide developers toward proper remediation.

4. Network Security Ability

Ops teams design and manage machine inventories, network architectures, and security controls, handling threats like malicious traffic, privilege escalation, and hidden backdoors while ensuring compliance and rapid incident response.

Additional Technical Areas

Beyond core monitoring, ops engineers handle hardware tasks (e.g., configuring Cisco switches, industrial routers), syslog aggregation to centralized servers, MySQL installation, clustering, read‑replica setup, VPN and domain proxy configurations, and even kernel‑level development and debugging.

Best Practices and Recommendations

vmsudo privilege reduction and password expiration policies

Automated operations monitoring, log collection, and Elasticsearch storage

DevOps integration for seamless code deployment

SQL audit monitoring for DDL and DML operations

MAC‑IP binding and VPN tied to employee IDs

Conclusion

Operations engineers act as the system’s firewall, safeguarding stability, handling high‑risk incidents, and providing the technical depth that developers often overlook; their work is essential, high‑skill, and far from "low".
