frontend partner tooling where appropriate.Lead development of APIs, ingestion pipelines, operational services, and partner-facing functionality that support high-volume retail environments.Own the reliability and long-term health of the systems you build, including monitoring, incident response, observability, scalability, and operational excellence.Architect for Scale & SimplicityDrive technical architecture decisions across distributed systems, service boundaries, integration strategies, data models, and platform reliability.Reduce complexity across the platform by identifying technical debt, improving maintainability, and establishing scalable engineering patterns.Champion engineering best practices across testing, API design, deployment strategies, observability, and TypeScript standards.Balance business priorities with long-term platform sustainability while helping teams make pragmatic technical decisions.Partner Collaboration & Enterprise IntegrationWork directly with retail partners, operational stakeholders, and enterprise account teams to understand integration requirements, operational processes, and technical constraints.Translate business and
