According to the high-end recruitment platform 100 offer Java talent inventory report released in the past 2018, Java is still the most popular, the amount of supply and demand recruiting largest technical language.

On this basis, the Internet industry for the recruitment needs of Java developers, but also the technical class positions in recent years, the largest amount of supply and demand, and changes in the most stable. Mianyao proportion of the number of business-to-Java engineers also paid much higher than other jobs, nearly 60% on the 100 offer platform, Java engineers demand the total demand, it can be said that under the current major companies "downsizing" in the background , Java engineers, especially senior Java engineer is still hard currency.

What can be called a senior engineer, and how to become a senior Java engineer it?

From the point of view of work time, a senior engineer with the general 3--5 years experience, enterprises have 3-5 years of experience in Java engineers, will require algorithms and programming capabilities solid foundation, there is a distributed, highly concurrent experience preferred, can be independent and responsible development of a module. Technically multi-skill, not just write Java, but also by analogy, the new technology required for the business can quickly learn to use to recruit a senior Java developer, for example:

We can see a few jobs from the above information:

1, even in this "downsizing" winter, the company is willing to pay for a senior Java engineer capable of. A senior programmer to achieve treatment 50w + is no problem. In the IT session is also circulating a point of view: the efficiency of a good programmer is 10 times that of ordinary programmer, anything for a little innovative projects, companies would rather pay twice the salary to choose a good programmer, I do not want to spend the same money to hire two mediocre programmer.

2, focusing on specific skills, business expectations for what a senior programmer is it? Almost all recruitment requirements will be referred to: Familiar with distributed systems, there is a distributed system development experience preferred.

The reason why the high threshold distributed systems, mainly in three aspects:

Knowledge involved too wide, and each concept is quite similar, discrimination is not high, such as distributed storage, distributed cache, RPC, micro-services, etc., often resulting in confusion when learning, there is a feeling foggy;

Scene of the practice of demanding, generally small projects will not be using these skills, can come into contact with a minor proportion of programmers to develop distributed systems, even if they know some relevant technical concepts of distributed, it is difficult to go to the floor, really the technique of forming the mind, not the practice of the technology will soon be behind you;

Anomalies giant, compared to stand-alone systems, distributed must take into account the complex anomalies on each link. For example, stand-alone system that does not exist is abnormal network, it is a common practice in a distributed system, any one of the influential distributed framework will spend a lot of code to solve these abnormalities.

If you work for 2 to 3 years, wanted to go to a distributed architecture and other studies, the most important thing is to systematize knowledge.
