Senior Software Platform Engineer

At Ironbelly, we are fundamentally changing how video games are made. Our AI team, led by industry luminaries and veterans, is building GameFrame AI —a platform that allows developers to create complex, professional games using natural language. We are the creators of a battle-tested gameplay framework that has been used to build and launch AAA games, and we're leveraging that expertise to architect the future of creative software.
This isn't just another AI wrapper. You'll be engineering a production-scale AI orchestration system that coordinates specialized agents to manipulate Unreal Engine in real-time, building technology that has never existed before.
A Note on the Role: This is an Applied AI Engineering Position
A seasoned backend/platform engineer with production experience building complex systems that use AI models and frameworks (like LangChain, LLM APIs, and vector databases).
~❌ This is NOT: A Machine Learning research or AI model-building role. We are not developing novel neural network architectures or training models from scratch.

As a Senior Software Engineer on our AI Platform, you will architect the intelligent backend that enables conversational game development.
Design and build the core of GameFrame AI, implementing sophisticated multi-agent (LangGraph Swarm) and single-agent (ReAct) systems that translate user requests into concrete game development actions.
Engineer the crucial link between our AI systems and Unreal Engine, developing a robust translation layer that allows AI agents to programmatically configure our proprietary, component-based gameplay framework.
Production AI Infrastructure: Architect and scale a distributed, multi-user backend on cloud infrastructure (AWS/GCP, Kubernetes). Implement enterprise-grade observability, monitoring, and robust failover systems required to support thousands of concurrent users with sub-second response times.

We are seeking a strong software engineer who is passionate about building at the intersection of AI and game development.
Expert-Level Backend Engineering: Deep, production-level experience in Python (3.11+), building microservices with frameworks like FastAPI, and designing with async/await patterns.
Proven experience with PostgreSQL, Redis, real-time WebSocket systems, and container orchestration using Docker and Kubernetes in a cloud environment (AWS/GCP).
Applied AI Systems: 1-2+ years of hands-on experience building applications that leverage AI systems. Game Development Context: A strong understanding of Unreal Engine concepts (Actors, Components, Blueprints) and workflows, gained through at least 2 years of professional or significant personal project experience.
Experience building production React applications with TypeScript and Next.js.
Advanced prompt engineering techniques (e.g., Experience designing and implementing evaluation frameworks for AI agent performance.
First 90 Days: Architect and deploy the core agent systems for game creation, implementing multi-provider LLM orchestration and production-grade memory systems.

• Scale the platform to support 500+ concurrent users, launch advanced agent capabilities, and build out continuous learning systems for our AI.
• 12+ Months: Lead technical strategy as we scale to thousands of users, contribute to new industry patterns for AI-driven creative software, and help establish our position as thought leaders in the space.

Comprehensive Benefits: Health, dental, and vision package , plus flexible PTO.
Opportunities for conference speaking, dedicated time for open-source contributions, and direct access to cutting-edge AI research partnerships.
