Change is constant across all industries, but more so within the IT sector due to rapid technological developments. Many companies are reporting a skills shortage of IT professionals. 

A McKinsey report notes that among the business areas with the greatest need to address potential skill gaps include IT, mobile, and/or web design and management.


The International Labour Organization (ILO) has said there is a shortage of Information and Communications Technology (ICT) professionals in many countries. ICT is a key economic sector and the backbone of the digital economy across all sectors.

The talent gap is increasing the pressure on the sector’s hiring practices while the field can also offer applicants competitive salaries.  

According to Robert Half Technology’s 2021 IT salary report, companies are doing whatever they can to fill this year’s most in-demand tech roles – which range from data to security-related occupations. 

Without a doubt, the impact from the pandemic can still be felt well into the year, affecting company’s hiring strategies. If you’re interested to break into the industry, here are some of the most in-demand IT careers you should know about:

Security professional (data, information, network, systems, cloud)

Security professionals are in demand as businesses increasingly rely on data to make strategic business decisions to everyday business operations.

They ensure enterprise IT initiatives remain safe from potential threats, both inside and outside the organisation. They’re also tasked with keeping on top of compliance regulations and future security trends, while ensuring the business’s hardware, software, and networks remain secure.

Cloud architect

Cloud architects oversee their organisation’s cloud computing strategy. They are also responsible for deploying, managing, and supporting cloud applications. These professionals typically have a strong understanding of multiple operating systems in addition to networking, programming, and security skills. 

A strong knowledge of cloud services such as Amazon Web Services, as well as experience with ITSM, I&O, governance, automation, and vendor management are often prerequisites to qualify.

Database administrator

A database administrator is responsible for maintaining the software used to manage and ensure the data used is easily accessible to those who need it. They also ensure that servers remain efficient and operational while overseeing data security, implementation, replication, backup, storage, access, and partitions. 

Programmer analyst

A programmer analyst is responsible for designing, coding, and testing new programmes along with providing detailed documentation of the process – using flowcharts and diagrams. These experts are tasked with designing programs based on client requirements and determining how much it will cost to build – while working closely with project managers. 

These analysts are also responsible for debugging and troubleshooting information systems and application programmes. 

Systems analyst

Systems analysts design techniques to solve business problems by analysing an organisation’s IT system. They’re responsible for investigating issues and problems, as well as fixing them as efficiently and cost-effectively as possible. These professionals can be found testing programmes and databases – making sure they’re working efficiently. 

Mobile applications developer

Mobile app developers need to be equipped with extensive knowledge of various mobile platforms currently available; they also  know how to develop applications that will work on Android, iOS, Windows, and other operating systems. 

These professionals typically have experience in programming, UX design, troubleshooting and debugging programs, and development. 


Network administrator

Network administrators handle LAN/WAN protocol, software, and hardware. This position requires troubleshooting and the need to be on call in case of an emergency or failure. 

Software developer

Software developers are responsible for designing, developing, installing, testing, and maintaining software systems. The role requires coding, designing, and building applications, websites, or mobile apps. These professionals should also be able to work with multiple programming languages such as C#, C++, HTML, Java, Microsoft .NET, and SQL Server. 

DevOps engineer

DevOps practitioners encourage faster code deployment with fewer deployment failures. Companies are on the lookout for engineers with the right experience in overseeing coding, scripting, and processes development. 

These engineers often manage IT infrastructure, provision resources, oversee software testing, and monitor performance after release. They help simplify code updates, enabling companies to continuously tweak and improve processes within the organisation for maximum efficiency.
