[Hiring] Senior Software Engineer @Mosaic Pediatric Therapy

Role Description

Mosaic Pediatric Therapy provides clinic-based and home-based ABA therapy for children with autism across North Carolina and Virginia. We are growing quickly, and we build and run a growing portfolio of internal software: custom web applications, AI-assisted operational tools, agentic workflows, and integrations with a modern Azure-based Lakehouse. These systems support clinical operations, billing, credentialing, and analytics.

Our software handles protected health information (PHI) and sits in workflows where accuracy and compliance are non-negotiable. We need a senior software engineer to turn that energy into well-designed, secure, maintainable applications.

This is a senior, hands-on software engineering role. You will design, build, ship, and maintain the internal applications and services that Mosaic runs on, and set the engineering standards for how software gets built here.

• About 70% of the role is software development such as application architecture, building features end to end, APIs and integrations, testing, code review, and production support.
• The other 30% covers the data and platform work those applications depend on, such as data pipelines into our Azure Fabric Lakehouse, CI/CD, cloud infrastructure, and monitoring.
• We are a Microsoft shop (Azure, Fabric, SQL Server, Microsoft 365).
• The role is highly cross-functional, working directly with the VP of Data Science, the Director of IT, and operational leaders across the business.
• You will also mentor internal builders who use AI-assisted development tools, helping them produce software that is safe, tested, and maintainable.

Qualifications

• 4+ years of professional software development, building and shipping production applications.
• High proficiency in at least one modern programming language, and comfort picking up others.
• Strong software engineering fundamentals: object-oriented or functional design, modular architecture, testing (unit, integration, end to end), debugging, and Git-based workflows.
• Experience designing and building APIs, services, and web applications.
• Track record of owning software end to end, from design through production support.
• Experience with CI/CD pipelines and production deployment workflows.
• Experience building on a major cloud platform (Azure preferred; AWS or GCP considered).
• Solid SQL and relational database design skills.
• Hands-on experience with AI-assisted development tools such as Claude Code, GitHub Copilot, Cursor, or similar.
• Understanding of secure coding practices and of handling sensitive or regulated data.
• Strong communication skills and the ability to work directly with non-technical stakeholders.
• Experience mentoring other developers or leading code review.

Requirements

• Experience in the Microsoft ecosystem: Azure, .NET, SQL Server, Microsoft Fabric, Entra ID, or Power Platform.
• Experience building ETL/ELT pipelines or working in Lakehouse or data warehouse environments.
• Infrastructure-as-code experience (Bicep, Terraform, or ARM).
• Experience building applications on top of LLMs or agentic frameworks.
• Experience in healthcare, ABA, EHR/EMR, claims, or other regulated environments.
• Exposure to HIPAA, HITECH, HITRUST, SOC 2, or related compliance frameworks.

Benefits

• Competitive salary based on experience.
• Health, dental, and vision insurance.
• 401(k).
• PTO and paid holidays.
• Remote-first flexibility.
• Equipment and tooling support.
