A growing software startup is seeking a Senior Software Architect to join its engineering team in Boulder, Colorado, working in a hybrid environment with three onsite days per week. This full-time opportunity offers the chance to help build SaaS products using C#, .NET, SQL Server, and modern development practices. Working alongside experienced founders and a small, highly collaborative team, you’ll play a key role in designing and developing a product intended to unify business operations into a single intelligent platform.

The team is looking for someone who thrives when given a problem to solve rather than a step-by-step set of instructions. You’ll be trusted to take ownership of features, explore solutions independently, and contribute to key technical decisions in an environment that values initiative and accountability. From application architecture and database design to feature development and technical planning, this role offers the opportunity to work across multiple areas of the platform while helping shape the future of a growing company.
