LLM Solutions Architect

Join Xsolla's Monetization Products team as a builder who shapes AI strategy and ships production-grade systems. You will design agentic architectures, develop shared LLM platform capabilities, prototype product hypotheses, govern LLM providers, and mentor engineers on production deployment practices.

Responsibilities

• Design end-to-end agentic architectures including tool-use schemas, intent parsing, multi-step orchestration, and safety guardrails.
• Define multi-modal interface strategy across UI, API, SDK, and agentic natural language.
• Design a horizontal LLM platform layer with shared RAG pipelines, prompt libraries, vector search infrastructure, and evaluation frameworks.
• Prototype AI product hypotheses before full engineering investment.
• Ensure systems include observability, documentation, and engineering runbooks.
• Shape AI product strategy and prioritization with Product leadership.
• Select and govern LLM providers and deployment strategies.
• Align Engineering, Product, and Design on agent-ready product surfaces.
• Mentor engineers on LLM integration, evaluation, and production deployment.

Requirements

• 5+ years of engineering experience, including at least 2 years designing and deploying LLM-powered systems in production.
• Production-scale experience designing agentic systems with tool use, function calling, reasoning, orchestration, and error recovery.
• Experience designing maintainable AI systems with observability, handoff documentation, and runbooks.
• Hands-on experience with OpenAI, Anthropic, Google Gemini, and at least one open-source model stack.
• Experience building RAG pipelines with vector databases and orchestration frameworks such as LangChain or LlamaIndex.
• Strong Python engineering skills for production-grade LLM services.
• Ability to influence product direction and communicate architectural trade-offs to engineers and executives.
• Gaming, payments, or e-commerce background is a plus.
• Fine-tuning, multi-agent orchestration, LLM evaluation, and AI compliance experience are pluses.

Benefits

• 100% company-paid medical, dental, and vision plans
