Sr. Azure dotNet AI Integration Developer

Berlin Packaging has been investing in technology across the enterprise, and our integration platform is at the heart of how our systems connect, communicate, and scale. As a Sr. Azure dotNet AI Integration Developer, you will be a hands-on practitioner at the center of that effort — designing and building enterprise-grade APIs, microservices, and full stack applications using Azure .NET and Azure API Management (APIM), backed by strong DevOps practices and experience across data and data warehouse platforms.

You will collaboratively develop solutions alongside onshore and offshore developers, architects, and cross-functional technology teams, contributing your expertise, elevating the work around you, and owning your deliverables end-to-end. The expectation is that you bring deep, proven experience and can operate with a high degree of autonomy from day one.

What You'll Do:

API, Microservices & Backend Development

• Develop scalable C#/.NET (ASP.NET Core) applications, REST APIs, and microservices using Azure cloud-native architecture and best practices.
• Build, deploy, and manage applications on Azure App Services, Azure Function Apps, Azure Static Web Apps, and Azure Logic Apps, ensuring scalability, reliability, and performance.
• Design, publish, secure, and manage APIs using Azure API Management (APIM), including authentication, policies, versioning, throttling, caching, monitoring, and API lifecycle management.
• Integrate Azure services including Service Bus, Event Hubs, Key Vault, Storage Accounts, and Azure SQL, and implement CI/CD pipelines using Azure DevOps.
• Leverage AI-assisted development tools — Claude Code, GitHub Copilot, or similar — to accelerate development, improve code quality, automate testing, and enhance developer productivity.

Cloud, Data & Data Warehouse Integration

• Develop data pipelines and integrations using Azure Data Factory, Databricks, Azure Functions, and Logic Apps.
• Deliver integrations across enterprise platforms including ERP, CRM, eCommerce portals, PIM systems, and data warehouse/lakehouse environments.
• Support consumption of APIs and data services by downstream reporting, analytics, and data warehouse platforms.

DevOps & Engineering Practices

• Implement and maintain CI/CD pipelines using Azure DevOps, Terraform, and GitHub, promoting engineering best practices across the integration and API codebase.
• Manage build, release, and environment configuration for .NET and APIM deployments.
• Maintain observability through monitoring, logging, and alerting tooling across the integration platform.

Quality, Security & Collaboration

• Implement API security standards including OAuth2 and JWT across .NET and APIM APIs.
• Provide L2/L3 production support, triaging and resolving integration issues with urgency and thoroughness.
• Collaborate effectively with onshore and offshore developers, sharing knowledge and contributing to a high standard of delivery across the team.
• Leverage AI-assisted development tools to accelerate productivity and improve code quality.

What We're Looking For:

Required Qualifications

• 8–10+ years of hands-on, full stack experience in enterprise API and integration development, with a track record of owning complex, mission-critical systems end-to-end.
• Strong hands-on expertise building APIs, microservices, and full stack (frontend, middleware, and backend) applications with Azure .NET (C#, ASP.NET Core Web API, Blazor/Angular/React), including publishing and managing APIs through Azure API Management (APIM) — security policies, versioning, and payload/performance optimization.
• Proven front-end development experience with modern frameworks (Angular, React, or Blazor), HTML5, CSS3, and TypeScript/JavaScript, with an eye for responsive, user-friendly UI/UX design.
• Strong command of REST, SOAP, JSON, and XML integration patterns, along with API design, versioning, and lifecycle management best practices.
• Solid DevOps experience: CI/CD pipeline design and implementation using Azure DevOps and GitHub, plus Infrastructure-as-Code using Terraform.
• Hands-on experience with Azure data and integration services — APIM, Azure Data Factory, Databricks, Functions, Logic Apps, Service Bus, and Key Vault.
• Strong SQL and relational database skills (Azure SQL/T-SQL), with familiarity in data warehouse or lakehouse architecture and data pipeline development.
• Experience with messaging and event-driven platforms (Azure Service Bus, Event Hubs, or Kafka).
• Experience with enterprise systems integration and implementation — including UI/UX considerations — across platforms such as MuleSoft, Oracle PeopleSoft, Salesforce, and data warehouse environments.
• Solid understanding of application and API security standards including OAuth2, JWT, and secure coding practices.
• Experience building or integrating AI/LLM-enabled APIs.
• Demonstrated ability to mentor junior/mid-level developers, lead architecture and design discussions, and drive the best engineering practices across the team.
• Comfortable working in a collaborative, cross-functional team environment with onshore and offshore contributors, including providing technical leadership and guidance.

Preferred Qualifications

• Microsoft Certified: Azure Developer Associate (or similar Azure certification).
• Experience with Azure OpenAI or similar LLM platforms in an integration context.
• Experience with event-driven architecture patterns at scale.
• Exposure to API governance frameworks and reusable integration design.
• Experience with Agile/Scrum delivery practices.
• Background in manufacturing, distribution, supply chain, or packaging industries.
