Principal Engineer

Principal Engineer - Ai & Platform ArchitectureKORE1, a nationwide provider of staffing and recruiting solutions, has an immediate opening for a Principal Engineer - AI & Platform Architecture that is fully remote.We operate a large-scale, multi-tenant SaaS platform supporting thousands of enterprise customers across the United States. Our backend infrastructure - built on event-driven, serverless AWS architecture - powers critical operational workflows, real-time transaction processing, integrations, and customer lifecycle management at scale. Now, the organization is evolving toward intelligent automation and agentic AI systems: autonomous, tool-using services capable of reasoning over platform state, interacting with production systems, executing workflows, and learning from outcomes within established guardrails. This Principal Engineer will lead the design and implementation of these AI-driven systems while also shaping the broader architectural direction of the platform. This is a highly hands-on technical leadership role focused on production engineering, system design, AI orchestration, platform scalability, and operational reliability. This individual will establish the engineering patterns, architectural standards, and operational safeguards that enable AI-enabled automation to function safely and effectively in high-scale production environments.Scope & ScaleLarge-scale multi-tenant SaaS environment supporting thousands of enterprise customersHigh-volume transaction and integration workloads across distributed
