AI Engineer (Python / LangGraph) — GameDev Solutions

We are building the next generation of AI Agentic Marketing Solutions specifically for the Game Development industry. We don’t just build simple chatbots; we build autonomous agents that plan, execute, and optimize User Acquisition (UA) and marketing campaigns for gaming studios.

We already have our technical leadership in place. Now, we are looking for a highly autonomous Senior Engineer who loves "getting their hands dirty" with complex agentic logic and scaling our AI platform.

The Role: Builder First

This position is for those who are passionate about coding and want to remain in a technical, individual contributor role. We need a "crafter" who enjoys diving into agent architectures, optimizing RAG pipelines, and writing high-performance code without the distraction of people management or "ivory tower" meetings.

Our Stack: Python (FastAPI, AsyncIO), LangChain / LangGraph, Redis, PostgreSQL, AWS.

Key Responsibilities

• Develop AI Agents: Design and implement complex, stateful workflows using LangGraph.
• Hands-on Engineering: Serve as a primary contributor to the core Python codebase. We expect daily commits and rapid iteration.
• Production-Grade AI: Work on agent reliability, mitigate hallucinations, manage agent memory systems, and build robust evaluation loops.
• Integrations: Connect AI agents with gaming metrics, store APIs (App Store/Google Play), and ad platform dashboards.
• Performance Tuning: Optimize LLM usage for latency and cost-efficiency.

Requirements

• Python Mastery: 5+ years of professional experience in Python. Deep expertise in AsyncIO, Pydantic, and FastAPI.
• AI/LLM Expertise: Proven experience with LangChain or LangGraph (essential). You understand the transition from simple prompts to complex, autonomous agentic reasoning.
• Solid Engineering Foundation: Strong knowledge of architectural patterns, event-driven systems (NATS/Kafka), and Vector Databases (Pinecone, Weaviate, etc.).
• Startup DNA: You prefer "shipping today" over "perfecting tomorrow." You thrive in a fast-paced environment where speed is a core feature.
• GameDev Interest: A genuine interest in the gaming industry and its KPIs (LTV, ROAS, Retention).

What We Offer

• Focus on Code: Minimal bureaucracy. Your time is spent solving hard technical problems, not in management meetings.
• High Impact: Your code directly defines the "intelligence" of our marketing agents.
• Elite Team: Work alongside a Technical Lead and other senior experts who value excellence and relentless improvement.
• High Reward for High Performance: Competitive salary + Advanced Bonus System (We reward those who build the business with us).
• A professional team that has your back. We work hard, but we support each other 100%.
• Medical Insurance in Ukraine and Multisport program in Poland.
• Offices in Ukraine (Kyiv, Kharkiv) and Poland (Wroclaw) or Remote.
• All necessary equipment and workstation space.
• Legal & Accounting services.
• English classes and Education reimbursement.
• Incredible corporate parties and other activities (when we aren't saving the world).
