About Medical Guardian 

Medical Guardian is building the next generation of connected health technology. We’re unifying customer portals, caregiver tools, ecommerce, and IoT device management into a modular, cloud-native platform on Microsoft Azure. 
We’re evolving from legacy systems into a scalable, microservices-based ecosystem powered by .NET, React, and Azure Functions, with integrations across Salesforce, IoT telemetry, and our Intelligent Orchestration Engine (IOE). 

We’re looking for a Senior Software Engineer who thrives on solving complex problems, writing clean, maintainable code, and contributing to large-scale modernization efforts that have real-world impact. 

Role Summary: 

As a Senior Software Engineer, you’ll play a key role in designing, developing, and maintaining applications and services that power Medical Guardian’s future-state platform. 
You’ll work closely with other engineers, architects, and product managers to deliver high-quality software that supports our members, caregivers, and internal operations. 

This position is ideal for someone who loves building distributed systems, enjoys mentoring others, and can operate comfortably in a hybrid environment where legacy and modern architecture coexist.

• Build with CI/CD pipelines (GitHub Actions or Azure DevOps) and participate in code deployments through automated processes.
• Monitor application performance, debug issues, and collaborate with QA on regression and functional testing.
• Follow best practices for observability, telemetry, and secure development (e.g., Azure App Insights, Key Vault).
• Contribute to continuous improvement of codebase health, documentation, and technical standards.

4. Mentorship & Teamwork 

• Support and mentor mid-level and junior developers by reviewing code, explaining design patterns, and guiding technical decisions.
• Collaborate cross-functionally with Product, QA, DevOps, and Data Engineering to ensure timely, high-quality releases.
• Share learnings and improvements across the engineering team through documentation and informal technical sessions.
