Digital Test Builder (Junior)

As a testbuilder, you will translate content created by our researchers into working, interactive online tests within the Cebir/TASC test platform. You will work closely with a team of researchers who provide the test content, assignments, scoring logic and reporting requirements.

Your responsibility is to turn this input into a smooth, reliable and user-friendly candidate experience. You will make sure that every test works correctly, looks clear to the candidate and supports the scientific and practical goals of the assessment.

Tech stack

What you’ll do

• Build and maintain online tests by setting up new tests and adapting existing ones.
• Create interactive test experiences by connecting research content to components such as selection lists, input fields, tables, timers, navigation flows, feedback, media and other interactive elements using Blade templates, JavaScript and SCSS.
• Work closely with researchers to translate specifications, texts, images, test properties and answer logic into technically functioning tests.
• Contribute to reporting by helping implement reports that make candidates’ results easy to interpret for our clients and consultants.
