About the role

Headquartered and incorporated in Los Angeles, California, Xsolla operates as the merchant of record and has helped over 1,500+ game developers to reach more players and grow their businesses around the world.

Design end-to-end agentic architectures - tool-use schemas, intent parsing, multi-step orchestration, and safety guardrails - engineered for long-term ownership by product engineering teams, not solo maintenance.
Design the horizontal LLM platform layer - shared RAG pipelines, prompt libraries, vector search infrastructure, and evaluation frameworks - that product engineering teams can build on and operate independently.
Prototype rapidly to validate AI product hypotheses before full engineering investment. Prototype acceptance by product teams is a primary success signal.
Drive alignment across Engineering, Product, and Design on what 'agent-ready' means for each product surface.
Mentor engineers on LLM integration patterns, agent evaluation, and production deployment practices - building the team's capability to own what you design.
Experience designing AI systems for engineering team ownership - including observability standards, handoff documentation, and runbooks that let other teams maintain what you build.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses.
Experience building RAG pipelines with vector databases and orchestration frameworks (LangChain, LlamaIndex, or custom).
Together, we're not just building a business
Together, we're not just building a business; we're cultivating a community that values creativity, collaboration, and the transformative power of play.

The ability to influence product direction, prototype rapidly, and communicate trade-offs clearly to both engineers and executives will be key to your success in this role.
If you have questions regarding our hiring practices, please contact careers@xsolla.com.
Hands-on experience with major LLM APIs (OpenAI, Anthropic, Google Gemini) and at least one open-source model stack.
Demonstrated ability to influence product direction: you have shaped what gets built, not just how.

Background in gaming, payments, or e-commerce - understanding of developer workflows, monetization models, or merchant operations.
Fine-tuning experience (PEFT/LoRA) for domain-specific model adaptation.
Experience with multi-agent orchestration frameworks (AutoGen, CrewAI, or custom).
Familiarity with LLM evaluation frameworks (RAGAS, DeepEval, or custom harnesses).
Exposure to EU AI Act, GDPR, or other AI compliance frameworks.

Strong technical architecture skills are essential, along with experience in designing and deploying LLM-powered systems in production.

This includes 100% company-paid medical, dental, and vision plans, unlimited Flexible Time Off, and a personalized career roadmap for each employee.
