Back-End Engineers are vital to the architecture and functionality of web applications, focusing on server-side development and database management. They are responsible for creating and maintaining the technology that powers the components which enable the user-facing side of a website to function. Their expertise ensures that applications are secure, efficient, and capable of handling large volumes of data.

What are the main tasks and responsibilities of a Back-End Engineer?

A Back-End Engineer typically undertakes a variety of tasks that are essential for building and maintaining the back-end of web applications. Their primary responsibilities often include:

Server-Side Development: Designing and implementing server-side logic, ensuring that applications run efficiently and effectively.
Database Management: Developing and managing databases, ensuring data integrity and security while optimizing performance.
API Development: Creating and maintaining application programming interfaces (APIs) that allow different software components to communicate effectively.
Code Optimization: Writing clean, maintainable, and efficient code, continuously improving existing applications to enhance performance.
Security Implementation: Implementing security measures to protect applications from vulnerabilities and ensuring compliance with data protection regulations.
Collaboration: Working closely with front-end developers to integrate user-facing elements with server-side logic, ensuring a seamless user experience.
Testing and Debugging: Conducting thorough testing and debugging of applications to identify and resolve issues before deployment.
Technical Documentation: Creating and maintaining documentation for back-end processes, APIs, and system architecture for future reference and onboarding.
Performance Monitoring: Monitoring applications for performance issues and making necessary adjustments to improve efficiency and user experience.
Continuous Learning: Keeping up-to-date with emerging technologies, programming languages, and best practices in back-end development.

What are the core requirements of a Back-End Engineer?

The core requirements for a Back-End Engineer position typically include a blend of technical skills, programming knowledge, and experience in back-end development. Here are some key essentials:

Educational Background: A bachelor’s degree in computer science, software engineering, or a related field is often preferred.

Common Back-End Engineer Required Skills

Over 200,000 Candidates Can't Be Wrong

This was a great platform to give the exam and was pretty easy to use for me, even as a newbie to this platform.

Udaya

Senior data science candidate for consumer good multinational

Overall, I found the test to be well-designed and comprehensive, effectively assessing the relevant skills and knowledge required for the position. The questions were thought-provoking and challenged me to think critically.

Sami

Senior marketing manager candidate for leading SE Asia corporate

That was definitely my first time ever being interviewed for skill assessment with the Alooba platform. Great experience and the value bestowed through such means is utterly respected on my behalf! I believe such online assessments should become more and more ubiquitous.

Yoav

Senior strategy manager candidate at global travel giant

The test is designed very well where it tests you different aspect of data comprehension. From data reading, data analysis, Excel formula, inference, and pattern recognition. The free response test is very interesting where it is simple enough to test your communication skill.

Our Customers Say

I was at WooliesX (Woolworths) and we used Alooba and it was a highly positive experience. We had a large number of candidates. At WooliesX, previously we were quite dependent on the designed test from the team leads. That was quite a manual process. We realised it would take too much time from us. The time saving is great. Even spending 15 minutes per candidate with a manual test would be huge - hours per week, but with Alooba we just see the numbers immediately.

Shen Liu, Logickube (Principal at Logickube)

I wouldn't dream of hiring somebody in a technical role without doing that technical assessment because the number of times where I've had candidates either on paper on the CV, say, I'm a SQL expert or in an interview, saying, I'm brilliant at Excel, I'm brilliant at this. And you actually put them in front of a computer, say, do this task. And some people really struggle. So you have to have that technical assessment.

Mike Yates, The British Psychological Society (Head of Data & Analytics)

We get a high flow of applicants, which leads to potentially longer lead times, causing delays in the pipelines which can lead to missing out on good candidates. Alooba supports both speed and quality. The speed to return to candidates gives us a competitive advantage. Alooba provides a higher level of confidence in the people coming through the pipeline with less time spent interviewing unqualified candidates.

Scott Crowe, Canva (Lead Recruiter - Data)

How can you accurately assess somebody's technical skills, like the same way across the board, right? We had devised a Tableau-based assessment. So it wasn't like a past/fail. It was kind of like, hey, what do they send us? Did they understand the data or the values that they're showing accurate? Where we'd say, hey, here's the credentials to access the data set. And it just wasn't really a scalable way to assess technical - just administering it, all of it was manual, but the whole process sucked!
