Staff Software Engineer [.Net, MVC, AWS, AI]

We're looking for a Staff Engineer who can lead both product engineering and cloud infrastructure across a mature .NET platform running on AWS. Your immediate focus will be helping modernize and scale a business-critical application using C#, .NET, React, TypeScript, AWS, and CI/CD automation. What's particularly interesting about this opportunity is where the platform is headed next. As part of the long-term technology strategy, you'll play a key role in evaluating and driving the evolution of the platform toward a more modern architecture centered around React, Node.js, AWS Cloud Services, AI-powered capabilities, and cloud-native engineering practices. This means you'll not only help solve today's engineering challenges but also influence the future technical direction of the product. For engineers who enjoy owning architecture, cloud infrastructure, DevOps, and product delivery end-to-end—and who are excited by the opportunity to work with the technologies shaping the next generation of software platforms—this role offers the chance to have a significant impact at the Staff Engineer level.
