12 Essential Operations Roles Every Tech Team Needs

Operations is the core pillar of internet, IoT, and other information systems; without the silent work of ops, today’s digital services would not run stably or prosper.

1. Implementation Operations

Implementation engineers deploy products or solutions to customer environments, handling requirement research, hardware/software preparation, installation, configuration, training, post‑sale service, and technical support, as well as system testing and issue resolution.

2. System Operations

Responsible for IDC, network, CDN, and foundational services (LVS, NTP, DNS); asset management, server selection, delivery, and maintenance; real‑time monitoring of system status to promptly detect and resolve issues.

3. Desktop Operations

Focuses on endpoint devices such as printers, PCs, laptops, handling hardware maintenance, software installation/upgrades, domain and security policy management, and communication terminals like VoIP and video‑conference devices.

4. Pre‑sale Operations

Provides technical support during the pre‑sale phase, assisting sales with consultations, technical demos, gathering user requirements, and proposing solutions; requires strong technical knowledge and communication skills.

5. Application Operations

Manages online service changes, status monitoring, disaster recovery, and data backup; conducts routine checks, emergency fault handling, and covers design review, service management, resource management, and backup planning.

6. Database Operations

Designs data storage solutions, database schemas, indexes, and performs SQL optimization; handles database changes, monitoring, backup, high‑availability design, and must be proficient with MySQL, Oracle, PostgreSQL, and middleware to ensure data integrity and security.

7. Automation Operations

Automates operational tasks using scripts and tools to achieve automated system deployment, configuration management, fault handling, and performance monitoring.

8. DevOps

Bridges development and operations, participating in requirement reviews, testing, and deployment to ensure rapid, stable delivery of software; promotes DevOps culture and practices.

9. Big Data Operations

Maintains and manages big‑data platforms, deploying, configuring, and optimizing components such as Hadoop, Spark, Flink, HBase, StarRocks, Doris, ClickHouse, and Hive; optimizes data processing pipelines, adjusts JVM parameters, and plans cluster scaling.

10. Security Operations

Handles security hardening for networks, systems, and services, performing regular scans, penetration testing, developing security tools, incident response, establishing security policies, training, risk assessment, and compliance.

11. Cloud Operations

Manages resources and environments on cloud platforms, including deployment, configuration, monitoring, and optimization of cloud servers, storage, and networking, with familiarity across major cloud providers.

12. Low‑Voltage Operations

Maintains low‑voltage systems such as data‑center monitoring rooms, access control, parking systems, performing regular maintenance, hardware monitoring, patch updates, and rapid fault repair to ensure stable operation.
