Hiring company HackerRank released its 2023 Developer Skills Report on November 10th. The report shows the most demanded skills. Trends show the popularity of data science and data security in the future job market.

According to the report, 2023 will require a diversity of skills in the basics and specialties. An employee with diverse skills can achieve higher positions. For example, data researchers need both programming skills and cybersecurity experience.

This trend can worry older developers who may find it difficult to learn new skills. But they don’t have to acquire these skills to be successful. Preferably, they should have sufficient knowledge to be able to work together when necessary.

Current state of the tech industry

This year has introduced many changes in the technology industry. Although tech and data science professionals were in demand, jobs were less stable.

Twitter and Meta (Facebook) have laid off thousands of developers this year. In addition, Apple and Alphabet (Google) have reduced settings. However, the demand for tech talent remained. Cybersecurity alone reported no unemployment in September.

To solve this problem, companies can employ a variety of tactics. On the one hand, companies that need talent can upskill their existing employees or outsource tasks.

But there are few options for employees. However, according to the report, employees need to upskill to stay on top. In addition to their basic knowledge, employees need advanced skills to be successful in 2023.

Developing the skill requirement

In the tech industry, just mastering a single skill is not enough. Nowadays it’s all about combining different skills. For example, SAP or FileMaker developers can add SQL know-how to their CV.

However, database development is not the only area where this principle will be applied. Every sector in the technology industry is introducing new tools. Mastery of these tools puts employees ahead of the rest of the talent.

In many cases, new opportunities can open up for companies that hire someone with expertise in new tools. Since agile management is in demand today, companies are well advised to have employees with different skills.

Likewise, the networking industry can benefit from employees who know many tools. Businesses looking for monitoring tools will benefit from hiring talent with knowledge of products such as KerioControl and IPv6 protocol management.

Data Science with a focus on Cybersecurity

Data science will be the most in-demand skill in 2023. However, data science is a broad field. In general, it is a cross section of IT skills, mathematics and economics.

One thing to note for most job applicants in 2023 is that only a subset of data science will be in demand. Additionally, data science is a career path with phenomenal demand. However, for job seekers, it is better to focus on cybersecurity and IT.

Complex mathematics should come second. It helps professionals understand how project models work.

And in the current era of big data, assembling and streamlining data is highly beneficial. In financial services and banking, employees with a math background will adapt faster.

Java, Python, C++, JS and SQL are still at the top

New software is constantly coming onto the market. But programming languages ​​and tools have remained the same for decades.

First published in 1974, SQL is half a century old. Despite this, it is still popular today. Even new developers prefer it as the best resource.

JavaScript has also been around since December 1995. However, it is still a relevant requirement in many professions.

Ideally, a new developer should master all five programs. While most companies require proficiency in one of the five, certifications in all give candidates an edge.

REST API know-how in high demand

Representational State Transfer Application Programming Interface or REST API as a concept has been around for over two decades and only recently started to attract attention. REST API has become an integral part of application development.

To learn the REST API, techies need to know HTTP. From there, the REST API uses common sense problem solving. Mainly, it connects two software programs to make drawing information easier.

With the rise of e-commerce and internet-based services, REST API professionals will thrive.
