Senior Software Engineer

Summary The Sr. Software Engineer is a .NET-first full stack engineer building and operating our suite of SaaS healthcare applications and services. This role requires an AI-augmented engineering mindset—using approved AI-assisted and agentic development tools (e.g., Claude, Cursor, GitHub Copilot) to accelerate design, implementation, testing, and documentation while maintaining high standards for security, reliability, maintainability, and traceability. As part of a collaborative Agile team, you will own end-to-end delivery across application and data layers, uphold quality standards through automation and testing, and mentor junior engineers as a trusted subject-matter expert. Responsibilities • Lead the research, design, development, deployment, and sustainment of secure, scalable, highly available production software. • Own delivery end-to-end across UI/API/service and database layers, including code quality, testing, and production readiness. • Partner with Product Management to ensure solutions meet business needs, align to intent, and balance usability, performance, and maintainability. • Create and maintain technical design documentation aligned to business requirements and solution architecture. • Define and enforce engineering best practices using a modern SDLC with CI/CD, automation, auditability, automated testing, and infrastructure/policy as code. • Drive an AI-augmented SDLC using AI-assisted and agentic workflows (e.g., Claude, Cursor, Copilot) for design, implementation, refactoring, testing, and documentation with appropriate security and quality controls. • Ensure AI usage aligns with enterprise expectations: use approved tools; follow security best practices; validate outputs; and apply the same review/testing/security standards to AI-generated work. • Build and maintain APIs and services (REST/gRPC) with strong design practices (versioning, backward compatibility, clear contracts). • Provide technical expertise across relational and NoSQL data stores and application logic, including data modeling, schema design, and query optimization. • Tune queries and refactor business logic for performance; implement concurrency controls to support multi-user functionality. • Improve operability and reliability through production-focused engineering, including monitoring/alerting and actionable diagnostics (e.g., Application Insights). • Collaborate with architects and engineers to deliver end-to-end solutions that are high-performing, reliable, scalable, and operable. • Mentor junior engineers and serve as a subject matter expert (SME); provide constructive code review and technical guidance. • Build simple, intuitive products and communicate technology solutions effectively across levels to build trust and alignment. Competencies for Success • Enjoys solving hard problems and learning quickly. • Self-driven, diligent, and delivery-focused; comfortable owning outcomes end-to-end. • Motivated to build innovative products that improve healthcare. • Collaborates well, communicates clearly, and gives/receives feedback constructively. • Enjoys mentoring and helping others grow. Required Qualifications • 6+ years of experience delivering web-based applications and services. • Strong CS fundamentals: object-oriented design, data structures, APIs/ and common web application patterns. • Strong proficiency in C# / .NET (modern .NET/.NET Core) and object-oriented design. • Experience in Azure, including AKS, App Services, Function Apps, and operational tooling (alerts, monitoring, notifications, Application Insights). • Experience using AI-assisted and agentic development approaches with tools such as Claude, Cursor, and GitHub Copilot to improve delivery speed and quality. • Experience with modern testing practices, including TDD, unit testing frameworks, and automated test tooling. • Understanding of web service standards and technologies (JSON, REST, gRPC). • Experience with data stores and formats such as MS SQL, Elasticsearch, Databricks, and Parquet (or equivalent). • Experience with GitHub and CI/CD pipelines. • Strong communication skills, able to explain and document complex ideas clearly and concisely. Preferred Qualifications • Experience with JavaScript frameworks such as Angular or React. • Experience with microservices and containerization (Docker, Kubernetes). • Knowledge of big data technologies such as Databricks and Spark. • Strong debugging skills and ability to learn new technologies quickly. • Understanding of cloud architecture and distributed system design. • Knowledge of healthcare data standards (HL7, FHIR, EDI X12). • Knowledge of healthcare revenue cycle workflows, EMRs, and practice management systems.
