7 Recommended Skills for IT Engineers to Acquire in 2021


7 Recommended Skills for IT Engineers to Acquire in 2021

In Japan, where there is a chronic shortage of IT talent, there are many job postings that are overwhelmingly disproportionate to supply and demand.

The career path of an engineer is different from person to person, and there is nothing wrong with learning new technologies according to one's own curiosity if it leads to one's own market value, but in reality, it is very important to be willing to learn skills that are not being handled by enough people in order to increase one's market value as an engineer.

Why IT Engineers Should Get a Certification


The knowledge and skills of IT engineers are acquired through practical work, but it is not uncommon for them to be dependent on specific information systems and development environments and to lack the ability to apply them. Since the certification exam comprehensively tests the knowledge and skills of the job title and product, you can aim to become a true specialist while studying for the certification.

In addition, Japanese companies vary widely in the definition of job titles and the tasks they are responsible for, and experience at Company A may not be directly applicable to Company B. Qualification holders can prove that they have a certain skill set, which is advantageous for self-promotion and selection when changing jobs.

Furthermore, it is not uncommon for qualifications to be a condition for assignment to some projects. This is often the case with government projects and infrastructure-related projects, where certification may be required for external appeal and credibility.

Workday, a cloud service for human resource management and financial management, has been adopted by more than 3,000 companies and is rapidly growing globally. In Japan, large companies such as Glico, SONY, Rakuten, Nitori, and HITACHI have already implemented Workday, and it has been attracting a lot of attention in recent years. Anyway, there is an overwhelming shortage of engineers who can handle Workday in Japan, and just having a Workday certification on your resume is enough to make you stand out from the crowd. In Japan, there is an overwhelming shortage of engineers who can handle it.


ServiceNow, a provider of ITSM (IT Service Management), was ranked number one in Forbes' annual ranking of the world's most innovative companies in 2018, and is also growing rapidly in Japan, driven by DX. ServiceNow also has a certification system, which will be very advantageous for your future career.

No-Code Development

No-code development tools have recently been gaining momentum in Japan, and we have seen a rapid increase in the number of no-code developer jobs in recent years. No-code development tools range from those provided by large companies such as Google Table and AWS Honey Code to those provided by venture companies such as Adalo, Bubble, and Glide. The learning cost is very low, so it's a good idea to start by playing around with the platforms that interest you. There are two main types of no-code tools: those for ToB and those for ToC. The former are used to improve business efficiency in the context of DX, while the latter appeal to the demand for fast and low-cost application development. In any case, no-code has been rapidly gaining market share in recent years, and according to No-Code Japan, it is predicted that about 30% of IT engineers will use no-code on a daily basis.

Quantum computing

Quantum computing

Recognizing that quantum computing is an immature technology, Ken Washington, Ford's CTO, said, "It's exciting to see that quantum computing is in the very early stages of technological progress. It's exciting that we're in the very early stages of quantum computing, which means that if we pay attention and work at this early stage, we'll have an advantage when the technology matures. In other words, if you pay attention and work on it in this early stage, you will have an advantage when the technology matures," he said, emphasizing the advantage of entering the market now as an early adopter. In fact, a number of large companies in Japan have started demonstration experiments of quantum computing, and we are receiving an increasing number of inquiries.

MLOps Operators

MLOps Operators

MLOps refers to the cycle from the implementation of machine learning models to the operation of the machine learning system by having the Machine Learning/Development team and the Operations team collaborate with each other. It goes without saying that low-level machine learning engineers can earn high remuneration, but if you don't have the time to learn machine learning from scratch, you may want to consider working as an MLOps who introduces machine learning. If you are interested in working as an MLOps operator, I highly recommend it.

Functional Languages

Functional Languages 

In Japan, functional languages are also in chronic short supply, and the jobs for engineers who can handle functional languages such as Haskell, Ocaml are all very expensive. Although the threshold is high, it is a highly recommended skill to acquire if you have the spare time, as it will be an overwhelming differentiator.



Blockchain is no longer overvalued as it was at one time, and society has begun to make a sober assessment of it. There is still a lot of talk about virtual currencies, and there is a certain demand for NFT (Non-Fangible Token) and De-Fi derived from virtual currencies. Demand for these topics ebbs and flows as the price of virtual currency fluctuates, but research and development will not disappear in the future, and the industry itself is growing steadily. There is a chronic shortage of blockchain engineers, at least in Japan, and they will continue to be hard to come by.
