Senior FullStack Software Engineer

About this role

Arionkoder is an AI consulting firm helping companies build, embed, and own AI systems that drive real business outcomes. We combine Product Development, Artificial Intelligence, and Team Augmentation to craft digital products and solutions that create lasting impact — guided by a human-centric approach and a commitment to pushing the boundaries of what technology can do.

We are looking for a Senior Full-Stack Engineer to design, build, and ship features end-to-end across one of our core product teams — from the interface a user touches, through the API, down to the data. You own meaningful parts of the product front to back: shaping the approach with your team, building both the UI and the services behind it, testing them, and running them in production. This is a hands-on role: most of your day is spent writing, reviewing, and debugging real code across the stack, with the autonomy to make sound technical decisions and the judgment to know which ones to raise.

You care about more than making it work. You think about edge cases, failure modes, performance — both on the server and as the user perceives it — accessibility, and the engineers who'll read your code next. You collaborate closely with product managers, QA, and fellow engineers to turn ambiguous goals into reliable software, and you push back early when requirements don't add up. You bring an AI-first working style — using AI tooling daily to move faster across design, coding, and review — with the judgment to catch where its output falls short.

This is not a role for someone who lives on only one side of the stack. We need an engineer who's genuinely comfortable building and owning a feature from the component to the database, takes it from ambiguous intent to shipped, reliable software, and raises the bar for the team around them
