Principal Software Engineer, Backend Systems

RoleRegrello is on a mission to redefine enterprise software, and we’re looking for a Principal Software Engineer, Backend Systems to help push the boundaries of what’s possible. If you love designing and scaling complex backend systems, have shipped major projects or entire products, and can think fluently about distributed systems, data modeling, API design, and integrations, this role is for you. You’ll architect and scale our Go/Postgres/Redis/GraphQL backend, working alongside world-class engineers and product minds to drive high-impact projects, lead critical design discussions, and collaborate directly with customers to shape a platform that’s transforming supply chain, manufacturing, and beyond. The industry is rooting for us, and you’ll play a pivotal role in making it happen. This is a high-autonomy, high-impact individual contributor role, but if you’re interested in growing into people management, the opportunity is there depending on your interest and performance.
CompanyRegrello is a 60-person startup revolutionizing how the world’s most critical enterprises operate. Born out of the White House COVID Task Force in 2020 and backed by Andreessen Horowitz, Tiger Global, and Ram Sriram (first investor in Google), we're reimagining automation in supply chains—in which companies still communicate about $13T of annual shipments almost entirely via email—as well as in manufacturing and operations. This is a $220-billion market opportunity that’s been largely overlooked for over 20 years. Four years in, we're already powering pivotal enterprise use cases in multiple industries to a degree that is unheard of for companies at our phase, and we're actively growing to new enterprises in the USA, Europe, and Asia. Our team has experience building billion-dollar companies and includes veterans from Oracle, Palantir, Apple, Amazon, and Microsoft.
ProductWe’re building the AI-first ERP to replace decades-old giants like SAP and Oracle, transforming how enterprises operate. Our platform can generate any enterprise workflow application in minutes—a dramatic leap from the 1-2 years it traditionally takes IT teams to build them—giving process owners in supply chain, manufacturing, and operations the power to standardize, streamline, and drive their work to completion, no matter the complexity. This breakthrough is powered by our workflow, forms, and AI engines, as well as our in-house Large Tabular Model, a first-of-its-kind innovation. Customers aren’t just adopting our platform—they’re clamoring for more, rapidly expanding their use cases as we enter an exhilarating growth phase. As one user put it: “I’ve been waiting for this for 20 years.”
Culture and CompensationWe are a customer-obsessed, product-driven company that is building a flexible, hybrid/remote culture to enable the brightest minds in the industry. We are particularly interested in candidates based in our hubs of Seattle, San Francisco and New York, but we will consider candidates who live anywhere in the US, Canada, or Mexico. We have industry-leading compensation packages, including equity and health benefits. We are willing to sponsor US work authorization if needed.
