The Application Programming Interface (API) market is growing at an impressive Compound annual growth rate of 17.5 per cent and is expected to be worth $21.06 billion by 2030. This shows us how important an API developer is for a company. In addition, the API security market, a subset of the entire API industry, is expected to grow from $744 million in 2023 to $3.034 billion, an impressive CAGR of 19.95 per cent. So, today, in this article, we will discuss the tips one needs to remember while hiring an API developer.

What are the Responsibilities of an API Developer?

Before we delve into the responsibilities of an API developer, we must first understand what an API is. In simple terms, APIs are rules and regulations that two software use to communicate. This means that it can help a programmer interact with external systems, libraries, or services without knowing the exact details.

Types of API

So, what are the types of APIs that are there? Well, the short answer is many. However, the most popular types of API are based on use cases.

Web APIs

One of the most common types of APIs is web API. These are essentially used to establish communication between two servers or between a server and a client. There are usually two standards that web APIs use: The first is REST, which is used to handle simple data sources, and the second is GraphQL, for handling large sets of data.

Operating System APIs

These types of APIS are used when there is a need for two software to communicate with each other. Operating system APIs are famous because they allow users to access how an operating system works without the need for them to understand how they work internally. This massively helps them customize and innovate the product according to their client’s needs. Examples of Operating System APIs are POSIX and WinAPI.

Library APIs

Programmers use library APIs to access the functionalities of software developers without needing to understand their internal workings. Examples of Library APIs are the NumPy library and Java Collection Framework.

Hardware APIs

Hardware APIs allow programmers to establish interactions between the software and hardware components. With these APIs, the hardware components structure through a hardware meta-model. Some examples of hardware APIs are hardware_adc, hardware_base and hardware_claim.

API Developers are responsible for creating, managing, and maintaining APIs. They should be familiar with both the technical and business aspects of developing APIs. Some common skills include programming, database management, and website design.

Skills to Look for in an API Developer

1. API Design

API design skills are essential for any developer creating an API, and there are a few specific areas to think about when designing an API.

API design principles include being clear about your business goals, determining what data needs to be accessed, and designing the most efficient routes possible. Additionally, pay attention to security and authentication measures when developing an API.

2. Cross-platform development

When hiring an API developer, you will want to look for skills in cross-platform development. This means that the API developer is familiar with developing APIs that will work on both web and mobile platforms. Additionally, the API developer should have experience working with different programming languages, including those used for building web applications and mobile apps.

3. Front-end development

When hiring an API developer, find someone proficient with both front-end and back-end development. It is important to have a developer who can create an interface that is easy to use for your end users and also has the knowledge to build backend functionality. Additionally, ensure the developer you hire is familiar with RESTful APIs and has experience creating applications that use them.

4. Coding languages

API developers typically use a coding language to write the code that interacts with an API. Some popular languages API developers use include Java, Python, and Ruby. It’s important to choose the right coding language for the task at hand, as this can impact the overall efficiency and quality of the code.

5. API orchestration skills

When it comes to hiring an API developer, you’ll want to be sure to look for skills in orchestration. This means being able to plan and manage the flow of data between systems, ensuring that your APIs are working as intended and responding quickly in the event of errors.

6. API Integration knowledge

API integration knowledge is essential for any developer looking to create a successful relationship with an API. A well-versed developer will be able to understand the protocols and methods used by an API, as well as the parameters and responses that are returned. Additionally, they should have experience working with JSON, XML, and YML files, as well as object-oriented programming.

7. Programming tools

API(Application Programming Interface) developers need to be able to program in a variety of languages, such as Python, Java, or Ruby. While API developers need to have strong programming skills and knowledge and be able to work with code and databases. They need to be able to work on projects independently and have excellent problem-solving skills.

While the above-mentioned points are necessary for hiring a great API developer, the world is changing at a breakneck pace. Within the last three years, artificial intelligence has taken a big leap and entered various aspects of life. And this includes hiring as well.

So, how has AI impacted hiring? Well, let us introduce BarRaiser to you. It is your one answer to all the hiring questions. With BarRaiser, recruiters can now breeze through the interview process quickly without dropping the quality of the entire recruitment process.

So, let’s take an example of how BarRaiser would work while conducting a hiring for an API developer. Firstly, the recruiter will give AI instructions on how to generate an interview plan. These instructions can be very specific, like the timing of the interview, the rounds, the number of questions, and the experience required to apply for the job.

An example of this would be something like this =:

Create an interview questionnaire for the role of an API developer with five years of experience. The developer should be well versed in Python, Javascript, Java, REST, GraphQL SOAP, gRPC, JSON and XML MySQL, PostgreSQL, NoSQL, MongoDB, and Firebase. The interview will be for one hour.

So, with only a few simple lines of instructions, a recruiter created a questionnaire that would have taken hours to do manually. The advantage of BarRaiser is that it also helps the interviewer during the interview.

For example, if the interviewer has run out of questions during the interview, they can simply ask the bot to create new questions. In fact, they can also ask our tool to go through a candidate’s CV or even the context of the interview (BarRaiser records and transcribes all of its interviews).

Post-interview, the AI bot has two tasks: help the recruiter create a detailed analysis report on the performance of the candidate and create a report on the conduct of the interviewer on its own. Both reports are shared with all the stakeholders to ensure there is transparency in the recruiting software.

We also have taken stringent measures to protect our client’s data. This is why we are a SOC Compliance company. So, what are you waiting for? Come see the magic of BarRaiser and your hiring quality rise.
