Backend Developer with AI / LLM – Regular / Senior (remote in Poland)
This is a remote position.<\/p>
At Profitroom we build software AI\-first. Claude Code is our daily tool, and engineers own initiatives from idea to production with real freedom in how they get there. We value time\-to\-market and believe done is better than perfect \u2014 while the engineering bar stays high: AI is the tool, judgment is the craft.
<\/p>
Currently, we're looking for a Backend Developer to join our Loyalty Team.
<\/p>\n

\n <\/div>
We're looking for engineers who want to own initiatives end\-to\-end \u2014 from understanding the business problem, through designing the solution, to production and real customer impact. This role is open to both Regular and Senior engineers, and we'll tailor the scope of responsibilities and compensation to your experience.
<\/p>
The role
<\/h2>
You will join the Loyalty Team and take ownership of initiatives from understanding the problem through implementation, release and production. You'll participate in technical discovery by validating feasibility, identifying constraints and helping shape technical solutions before implementation begins. The Product Manager brings the vision and the problem \u2014 you own the technical solution.
<\/p>
Your strongest background will be backend development, but you're comfortable stepping outside it when AI and established patterns make it practical. When something genuinely requires deeper expertise, you know when to involve the right specialist.
<\/p>
What you'll actually do
<\/h2>\n \n - Build and maintain backend services using PHP, Laravel and Symfony.
<\/li>\n - Participate in technical discovery and help shape solutions before implementation starts.
<\/li>\n - Own initiatives through implementation, testing, release and production.
<\/li>\n - Design solutions before writing code, balancing speed, quality and long\-term maintainability.
<\/li>\n - Write automated tests as part of development and take ownership of the quality of what you ship.
<\/li>\n - Use AI throughout development, testing, documentation and code review.
<\/li>\n - Collaborate closely with Product Managers, Quality Assurance Specialists and other engineers.
<\/li>\n - Continuously improve systems rather than adding unnecessary complexity.
<\/li>\n - Participate in daily engineering rituals such as refinement, planning, reviews and retrospectives.
