About the role

Xsolla is seeking a Principal Engineer to lead the architectural development of the Shop Builder platform, focusing on agent-readable features. This role is the highest-level individual contributor position within the DevX and AI team, where the engineer will make critical decisions regarding platform capabilities, including UI as Data, custom blocks, themes, data binding, catalog, and payments. The position requires a hands-on approach to tackle complex technical challenges and establish standards that will shape the platform's future. Candidates should possess extensive experience in software engineering and a deep understanding of developer and AI interactions with the platform. The role does not involve management responsibilities but requires significant influence across the organization. This remote position is ideal for someone who thrives in a collaborative environment and is passionate about enhancing developer experiences. Xsolla operates as a global payments and commerce platform for the gaming industry, and the DevX and AI team is newly formed to address the need for dedicated ownership of developer-facing features.

ABOUT YOU We are looking for a Principal Engineer to take architectural ownership of the agent-readable Shop Builder platform. This is the most senior individual contributor role on the DevX and AI team, and the decisions you make here — which surfaces to expose, which formats to support, which standards to set — will bind the platform for years. You are not a manager, but your influence is org-wide. You define how developers and AI agents interact with Shop Builder's foundational capabilities: UI as Data, custom blocks, themes, data binding, catalog, payments. You are the technical authority on what the platform exposes and how, and you are deeply hands-on with the hardest parts of that work. ABOUT US Xsolla is a global payments and commerce platform for the games industry, used by thousands of publishers to monetize, distribute, and operate their titles worldwide. Shop Builder is Xsolla's storefront platform — used by publishers and game developers to launch and operate game shops, from straightforward catalog and webshops to fully custom storefronts built headless on our backend. For more information, visit xsolla.com. The DevX and AI team owns the public APIs, documentation, and AI features that give developers — and AI agents — the full surface they need to customize and extend Shop Builder. This is a net-new team of seven, standing up to fill a real gap: no dedicated team has owned the developer surface end to end. That changes now.
