We are seeking an experienced Senior Software Developer (Full Stack/Cloud) to serve as a senior technical contributor responsible for designing, developing, and supporting scalable full-stack applications and serverless cloud solutions, and essentially providing reliable services for State of Colorado residents.
This role requires deep expertise in JavaScript/TypeScript, React and/or Angular, Node.js/NestJS, REST APIs, SQL Server, and AWS.

To be successful in this role, you will be comfortable operating in a modern serverless environment and troubleshooting complex issues spanning the frontend, backend, database, APIs, and AWS infrastructure.

In this role, you will independently troubleshoot issues across full-stack technologies—including React/Angular, Node/NestJS, SQL Server, and APIs—while establishing robust development patterns to enhance application reliability, security, and performance. Beyond technical execution, you will provide leadership by mentoring developers, leading code reviews and design discussions, proactively identifying risks, and balancing delivery deadlines with long-term engineering quality and technical debt.
