Full Stack .NET Engineer

We are an AI-enabled engineering team, and we believe the future is about empowering engineers with the latest tools, building through custom skills, agents, and harnesses, and we are looking for people who embrace AI, are excited about the future, and want to help shape the way we embed AI tooling throughout our developer experience.

• Be adaptive and strike a good balance between speed and efficiency 
• Work with our technical support team to identify, reproduce, and remediate bug tickets 
• Build and deliver features through agentic tooling — designing, iterating on, and improving our custom skills, agents, and harnesses as part of the work 
• Contribute prompts, skills, and workflow improvements back to the team so our AI-enabled developer experience compounds

• Experience with Design Patterns, refactoring, OO Design and related areas 
• Practical hands-on experience with AI coding assistants and agentic engineering workflows, and a genuine appetite to work primarily through agents — owning architecture, review, and quality rather than typing every line 
• Exposure to building web services using Web API 
• An understanding of database design and development 
• Hands-on experience with HTML, JavaScript, CSS including jQuery 
• Strong attention to detail and work ethic

Our Mission: To provide an automated A/R platform that seamlessly integrates existing business processes for the SMB market. 

Our Core Values: 

How We Work: Our engineers work with agents and harnesses as a default, not an experiment. Our interview process includes a practical exercise using AI tooling. If that sounds like the way you want to build, you will thrive here; if you would rather write every line by hand, this is likely not the right fit.
