The role

We are seeking an enthusiastic and highly skilled Quality Assurance (QA) Developer to join our fast-paced and innovative digital marketing agency. As a key member of our dev team, you will work closely with our developer team to design, develop, and maintain backend systems that power the sites and applications of our clients.

What you'll do

Work closely with our Technology Lead, IA Developers and UX/UI Design Lead to test and develop features.
Review code produced with AI assistance before it reaches a client: check it does what the ticket asked, follows our conventions, and doesn’t contain invented APIs or bugs that look plausible at a glance.
Work with our AI Developer to figure out how to fix it: what’s actually wrong, what the fix should be, and whether it risks breaking something else.
Trace it to its cause — front-end, back-end or prompt — rather than stopping at the symptom, and see the fix through.
Try to break our AI features on purpose, and document every case that works.
Monitor Web Speed Optimization efforts after each release.
Proactively report to our internal Project Manager and IA Developers and manage your schedule to ensure all deadlines are met.
We’re hiring someone who wants to build, not only to fix. As you get comfortable, you’ll take on development tasks alongside the AI Developer on both internal tools and client features.

How you'll work

Located in Europe - this position requires you to work in accordance with our Spain office's working hours (10am-6pm CET)

Who You Are

Around 1 year of experience in web development or QA.
Able to read and write JavaScript, and comfortable around a modern framework (React or Vue).
Working knowledge of HTML5 and CSS3, enough to spot layout, responsive and cross-browser issues.
Understanding of back-end logic (PHP and/or Node) so you can follow a feature end to end.
Experience testing REST or GraphQL endpoints.
Experience working inside Git and in an Agile environment.
Comfortable working with AI assistants as part of your workflow - writing good prompts, reviewing generated code critically, and knowing when not to trust the output.
Any hands-on experience with LLMs, even personal projects.
A keen eye for detail, interactivity and animation.
A true team player who can work closely with others.
Any hands-on experience with LLMs, even personal projects.
