About the Role

We’re looking for a Fullstack Engineer with strong experience building AI-powered products to help us grow our gaming & infrastructure platform.

You’ll join a fast-moving, AI-first team where you’ll design, build, and ship features end-to-end — from model integration and prompt engineering to the UI users interact with. You’ll work with LLMs, video generation, and ML pipelines as part of your daily workflow, using AI tools to move faster and build better.

This role is ideal for someone who already builds with AI in production, thinks in terms of product value, and wants real ownership — not just coding tickets. At PlayMe, we move fast, avoid bureaucracy, and give engineers full ownership to make decisions and deliver impactful products used by real people.

Who You Are

• You have 5+ years of software engineering experience with a track record of shipping production-ready products;
• You are fullstack — comfortable working with both backend and frontend;
• You have hands-on experience with AI in production (LLMs, ML models, or generative pipelines);
• You’ve built or integrated solutions using LLMs, LangChain, MCP, or similar tools;
• You actively use AI tools (e.g., Claude Code, Codex) to improve your development workflow;
• You understand AWS ecosystem and basic DevOps practices;
• You think in terms of product impact, not just implementation;
• You’ve worked in small, fast-moving teams, shipping frequently and iterating quickly;
• You’re independent, ambitious, and ownership-driven;

• You have Upper-Intermediate+ English.

   

Nice to Have

• Experience with video generation, diffusion models, or multimodal pipelines;

• Background in machine learning (fine-tuning, inference optimization, evaluation).

   

What You’ll Do

• Build and ship AI-powered features end-to-end;
• Work with LLMs, generative models, and ML pipelines as core tools;
• Use AI agents and tooling in your daily development workflow;
• Own features from idea to production, including monitoring and iteration;
• Collaborate with engineers to define API contracts and product behavior;

• Continuously improve architecture, performance, and product quality.

   

We offer:

You will be working with a professional and motivated team of enthusiasts in the environment that brings up the best in everyone. We have no bureaucracy, and we give our colleagues complete freedom to make decisions and achieve brilliant results.

Our company is built on the ability to find the best people and provide them with everything needed to stay focused on what’s important to make our users even healthier, sportier, happier and better! We create a business environment that brings up the best in everyone.

Competitive salary. Compensation that will help you focus on your projects and personal development.

Professional Growth. We offer a possibility to attend internal, external courses, seminars and access to a corporate library. You will be working with a team of professionals to get insights and discuss ideas.

Health&Fitness. We provide employees with 20 days of paid vacation, sick leaves and medical insurance.

Rest. We organize team buildings, parties and various team activities to boost our collaboration.
