Build and maintain scalable, reliable infrastructure and distributed systems powering enterprise AI automation. | Strong full-stack engineering skills with experience in distributed systems, API orchestration, and cloud infrastructure. | Build the infrastructure layer powering enterprise AI automation Enterprise software integrations are still painfully fragile: workflows break silently, APIs fail unpredictably, systems drift out of sync, and teams waste countless hours maintaining infrastructure that was never designed for real-time operations at scale. For years, most data companies focused primarily on analytics because the underlying integration and operational tooling was too broken, unreliable, or difficult to use for powering critical business operations in production. You can think of Stacksync as Zapier for enterprise systems, but built for real-time and mission-critical operations at scale. Our platform powers mission-critical operations: supply chains manufacturers logistics companies healthcare organizations financial operations ecommerce businesses enterprise sales organizations When our systems run, orders move, invoices sync, warehouses operate, contracts renew, revenue gets recognized, and business workflows execute in real time.
