Job description
Full-time Bethesda, MD
Stackular is seeking a hands-on Principal Software Engineer to provide cross-stack technical leadership on a multi-year cloud-native modernization initiative supporting a federal research client within the National Institutes of Health (NIH).
This role operates as the senior engineering voice on a cross-functional team that spans application development, cloud infrastructure, data integration, automation, and security. The portfolio under modernization includes roughly twenty legacy applications transitioning from .NET, Oracle, and SAP BusinessObjects on VM-based hosting to an AWS-managed, microservices-based platform delivered through a federated GraphQL API layer and a React/TypeScript frontend.
This position is ideal for engineers who can both write production-grade code and exercise sound technical judgment when changes cross domain boundaries — reviewing architecture, APIs, infrastructure, and data work side-by-side, and helping a newly integrated DevSecOps team deliver coherent, secure, operable systems.
