• Support software distribution for connected and air-gapped instrument environments.
• Integrate packaging and release workflows into GitHub Actions CI/CD pipelines.
• Follow applicable regulated software development and release practices, including IEC 62304-aligned processes where required.

4. AI Agent Development & Engineering Productivity

• Develop AI-powered agents and workflows using LangGraph, MCP, LanEligible to workhain, or similar frameworks.
• Build Retrieval-Augmented Generation (RAG) pipelines using instrument manuals and technical support knowledge bases.
• Leverage AI-assisted development tools such as GitHub Copilot, Cursor, and Claude Code.
• Explore and implement AI-based solutions for code generation, pull request automation, test scaffolding, and developer productivity.

5. Cloud & DevOps

• Develop and deploy cloud-native services on AWS ECS Fargate.
• Work with AWS services such as S3, SQS, and CloudWatch.
• Build and maintain CI/CD pipelines using GitHub Actions or equivalent tools.
• Support infrastructure automation using Terraform and Infrastructure as Code (IaC) practices.
• Contribute to containerization, deployment automation, monitoring, and troubleshooting.

Required Skills & Qualifications

• 2-6 years of experience in full-stack software development, delivering production-ready applications.
• Strong hands-on experience with IoT development and Microsoft technologies, especially .NET and C# (Level 4 expertise).
• Experience developing backend applications and REST APIs using .NET/C# or Python.
• Proficiency in React, TypeScript, and modern frontend development practices.
• Practical experience with IoT communication protocols such as MQTT and AMQP, or instrument/edge software integration.
• Experience with software packaging, installers, containers, or software update mechanisms.
• Familiarity with CI/CD pipelines using GitHub Actions or equivalent tools.
• Experience using AI-assisted development tools such as GitHub Copilot, Cursor, or Claude Code.
• Strong problem-solving, debugging, collaboration, and communication skills.

Preferred Qualifications

• Experience in medical device software, clinical diagnostics, or in-vitro diagnostics (IVD).
• Familiarity with IEC 62304, FDA 21 CFR requirements, and regulated software development practices.
• Experience building and deploying AI agents using LangGraph, MCP, or LanEligible to workhain.
• Hands-on experience with AWS ECS Fargate, Terraform, and cloud-native architectures.
• Knowledge of Windows/Linux edge agents, MSI/NSIS installers, and delta-update mechanisms.
• Experience with legacy technology migration, particularly AngularJS, VB6, and TFS.
• Familiarity with healthcare data security, HIPAA-related considerations, and audit trail implementation.

Technology Stack

• Frontend: React 19, TypeScript, Tailwind CSS, Next.js
• Backend: .NET 8, C#, Python, FastAPI, REST, GraphQL
• IoT & Edge: MQTT, AMQP, Windows/Linux edge agents, instrument interfaces
