How about operation and maintenance?

No matter what operation and maintenance, the most basic duty of the operation and maintenance engineer is to be responsible for the stability of the service and ensure that the service can provide services to users 24 hours a day. On this basis, the main responsibilities of the operation and maintenance engineer are as follows:

1. quality: ensure and continuously improve the availability of services, ensure the security of user data and enhance the user experience.

2. Efficiency: use automation tools/platforms to improve the engineering efficiency of software in the R&D life cycle.

3. Cost: Optimize service architecture and performance tuning through technical means; Reduce costs and improve return on investment through the best combination of resources.

From the perspective of product life cycle:

1. Before product release: Be responsible for participating in and reviewing the rationality and operability of architecture design to ensure the efficient and stable operation of products after release.

2. Product release stage: responsible for using automation technology or platform to ensure that products can be released online efficiently, and then can be iterated quickly and stably.

3. Product operation and maintenance stage: responsible for ensuring the stable operation of products for 7 * 24 hours, during which various problems can be quickly located and solved; Continuously optimize the rationality of system architecture and deployment in daily work, and improve the stability of system services.
