Only What Matters – We simplify and focus on what drives impact.

We Do Hard Things Together – We solve tough problems as a team.

We help healthcare providers get paid accurately and on time—without getting stuck in the complexity of billing, coding, and compliance.

We help our customers make right easy—every day.

We’re looking for an experienced and strategic Software Engineer IV to play a key role in evolving and maintaining our CWCS/Registration systems.

What You’ll Do

• Collaborate within a small, agile team to design, build, and maintain enterprise-grade software solutions
• Lead development efforts across the stack, from UI (Angular) to .NET-based application logic and SQL database integration
• Contribute to the evolution of our cloud-native architecture, focusing on horizontal scalability, security, and performance
• Own and improve a key portion of the application architecture, becoming a go-to expert for that component
• Serve as a technical escalation point for field issues, designing and delivering solutions that are aligned with our software development lifecycle
• Participate in the full SDLC, from requirements gathering and prototyping through to testing and deployment, including test automation
• Occasionally lead cross-functional technical initiatives, working closely with engineering, architecture, security, and product teams to deliver impactful solutions

What You’ll Bring

• Bachelor’s or master’s degree in computer science or equivalent experience
• 10+ years of software development experience, ideally in enterprise product development
• Deep expertise in C#, .NET, SQL, and Angular, with at least 5 years of hands-on experience using these technologies
• Proven success in building and maintaining web applications with architectures that include: Web UI, RESTful APIs, .NET middle tier, ORM, and SQL back end
• Hands-on experience with cloud platforms (e.g., AWS, Azure) and container orchestration using Kubernetes
• Strong problem-solving skills and the ability to thrive in a fast-paced, collaborative, agile team environment
• Healthcare industry experience, especially in areas such as revenue cycle management, medical records, or HIM, is a strong plus
