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.

Key Responsibilities

1. Software Design & Development

Design, build, and maintain backend services using C# / .NET (ASP.NET Core, Azure Functions, Web API) hosted on Azure.
Develop front-end components and interfaces in React and TypeScript, integrating with APIs and headless CMS systems.
Contribute to the migration of PHP / CodeIgniter services into modular, cloud-native microservices.
Implement secure, scalable, and performant code aligned with Medical Guardian’s architectural principles.
Write automated unit and integration tests to maintain code quality and reliability.
Familiarity with AI-assisted development tools (e.g., Cursor, GitHub Copilot, Replit) for accelerating workflows, automating code generation, and improving delivery velocity

2. Architecture & Collaboration

Collaborate with the Application Architect and Engineering Manager to define service boundaries, design APIs, and optimize data flows.

Contribute to architectural decisions on event-driven patterns, service-to-service communication, and deployment pipelines.

Participate in peer reviews and offer constructive feedback to improve design consistency across teams.

Support integration with systems including Salesforce, IoT data streams, fulfillment, and campaign orchestration (IOE).

Design modular, API-first components compatible with the MG unified platform, ensuring reusability across multiple Medical Guardian apps.

3. Quality & DevOps Practices

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.

Qualifications & Skills :

Education :

Bachelor’s degree in Computer Science, Software Engineering, or related field (or equivalent experience).

Experience :

5+ years of software engineering experience, ideally across both backend and frontend development.

Experience designing and implementing APIs or microservices in production environments.

Familiarity with legacy frameworks (PHP / CodeIgniter, JavaScript) and modern cloud-native approaches.

Technical Proficiency :

Backend : C# / .NET Core, ASP.NET Web API, Azure Functions, SQL Server

Frontend : React, TypeScript, HTML / CSS, REST / GraphQL integrations

Cloud : Azure (App Services, API Management, Service Bus, Data Lake, AKS preferred)

DevOps : GitHub Actions or Azure DevOps for CI / CD, Docker, familiarity with containerized deployment

Data : Proficiency in SQL, understanding of event-driven and ETL workflows (Azure Data Factory, n8n)

Bonus Skills : Node.js for microservices, Salesforce API integration, IoT or messaging systems (MQTT / Event Hub)

Soft Skills :

Strong problem-solving mindset with attention to scalability and maintainability.

Excellent communicator, comfortable explaining technical concepts to peers and stakeholders.

Self-directed, curious, and eager to learn new technologies.

Candidates must be authorized to work in the United States without current or future need for visa sponsorship.

Must have the ability to work from our Philadelphia office on Tuesdays and Wednesdays.

Why Join Us :

Help modernize an entire platform serving hundreds of thousands of connected health devices and members.

Work with modern technologies in an Azure-based ecosystem while contributing to a meaningful mission.

Collaborate with passionate engineers who value clean code, shared standards, and continuous learning.

Hybrid flexibility : 2 days per week in the Philadelphia HQ with strong work-life balance.
