Senior developer

(fullstack)

We are looking for an experienced full-stack developer.

This role is for someone who wants to use AI to the fullest, not as a gimmick, but as a serious way to ship faster. We expect you to move quickly with AI assistance, but also to think clearly, challenge weak outputs, keep the architecture sane, and take responsibility for quality.

What you will do

• Turn ideas and rough flows into clear specifications and working product changes
• Build across frontend and backend, with ownership from concept to production
• Help create a development process where AI generates a large part of the implementation, but humans stay responsible for intent, review, testing, and final quality
• Over the next 12 months, most of your work will focus on our client Guestcloud.sk , where you will help enhance the platform with an AI-assisted CMS for event / invitation sites.
• We’ll also work together on our own exciting product, which we’re happy to talk about in more detail.

What we are looking for

• Strong senior engineering judgment
• Very high willingness to work with AI tools daily
• Ability to learn unfamiliar technologies quickly and reason from documentation
• Experience with a modern frontend SPA framework (Vue.js, React.js) and backend development in a modern language (experience or willingness to work with Python)
• Ownership: you can test your own work, think in systems, and deliver production-ready results
• Clear written communication, especially around specs, prompts, task breakdown, and handoff

Existing tech stack

Python, Django, FastAPI, Vue.js, React.js

Why this role is interesting

• Real influence on product direction and engineering process
• A chance to shape how a small team works in the AI era
• Broad scope, high autonomy, and room to improve things end to end
• Work focused on practical outcomes, not corporate overhead

Who we are

Infinit.dev is a software company working on client projects and its own products. We like strong engineering, open minds, practical AI, and people who care about quality without becoming rigid.

Since 2007, we have been building mainly Python and full-stack software for international clients.We value ownership, honesty, sharp thinking, and a working environment that is both demanding and sustainable.

We also invest in our own internal products and in better ways of building software.
