Associate Mern Stack Developer Jobs in Batavia, IL

Overview

We are looking for a skilled Platform Software Engineer to design and build the shared components, integration frameworks, and tooling that empower engineering teams across the organization. The ideal candidate brings hands-on experience with healthcare data standards, workflow automation, and full-stack web development. You will work at the intersection of backend services, cloud infrastructure, and healthcare interoperability-building the foundational layers that accelerate development velocity and consistency across multiple domains.

Key Responsibilities

• Platform Development: Design, implement, and maintain reusable platform components, libraries, and SDKs that enable engineering teams to build automation and integration solutions efficiently and consistently.
• Healthcare Integration: Develop and maintain integrations using industry-standard healthcare protocols and formats including EDI (X12), HL7 (v2/v3), FHIR (R4), and RESTful APIs connecting EHRs, payers, clearinghouses, and third-party systems.
• Workflow Automation: Design and maintain the automation platform and reusable RPA tooling-built on Python, Selenium, and OpenCV-that engineering teams rely on to develop, compose, and deploy automation workflows without reinventing foundational capabilities.
• API Development: Design and implement RESTful APIs and integration services that provide clean abstractions over complex healthcare transactions and downstream systems.
• Web Development: Contribute to full-stack web application development using Python (FastAPI) for backend services and React for frontend interfaces that support platform operations and tooling.
• Cloud Infrastructure: Deploy and manage platform services on Microsoft Azure, leveraging PaaS offerings such as App Services, Azure Functions, Logic Apps, and Azure SQL.
• CI/CD & DevOps: Operate comfortably within CI/CD pipelines using Azure DevOps or GitHub Actions; contribute to infrastructure managed via IaC tools such as Terraform, Bicep, or ARM templates.
• Compliance & Security: Ensure all platform components adhere to healthcare data privacy and security requirements (HIPAA), and follow Azure security best practices including RBAC, Key Vault, and Entra ID.
• Documentation: Produce clear, thorough technical documentation for platform components, APIs, integration patterns, and developer usage guides.
• Collaboration: Partner with cross-functional teams to understand integration needs, define platform standards, and provide technical guidance on platform adoption.

Requirements

• Proficiency in Python, with experience building production-grade applications and automation solutions.
• Hands-on experience with REST API design, development, and consumption.
• Familiarity with workflow automation and RPA tooling (e.g., Selenium, OpenCV, or similar frameworks).
• Experience with full-stack web development using FastAPI (backend) and React (frontend).
• Solid understanding of relational databases (MS SQL or equivalent), including schema design and query optimization.
• Experience with containerization (Docker) and orchestration (Kubernetes).
• Experience deploying and managing applications on cloud environments (Azure preferred).
• Understanding of healthcare data privacy and security requirements, including HIPAA compliance.
• Proficiency with Git and collaborative development workflows.
• Strong written and verbal communication skills, including the ability to write documentation oriented toward developer consumers.
• Collaborative mindset with experience contributing to shared or platform-oriented engineering efforts.
• Experience applying AI/ML techniques to automation workflows (OCR, NLP, predictive analytics).
• Familiarity with software design patterns and service-oriented architecture principles, with demonstrated ability to reason through system-level design trade-offs and contribute beyond individual feature delivery.

Preferred Qualifications

• Experience with Azure PaaS services (App Services, Azure Functions, Logic Apps, Azure SQL, Key Vault, Azure Monitor).
• Experience developing healthcare integrations using EDI (X12 837/835/270/271), HL7 (v2 or v3), and/or FHIR (R4) standards.
• Familiarity with CI/CD tools (Azure DevOps, GitHub Actions) and Infrastructure as Code (Terraform, Bicep).
• Familiarity with EHR/billing systems, healthcare web portals, or revenue cycle management processes.
• Microsoft Certified: Azure Developer Associate or equivalent certification.
• Familiarity with mobile application development (iOS/Android or cross-platform frameworks); comfort advising on mobile integration patterns or consulting on contractor-built mobile solutions.
