Full Job Description SUMMARY:

The Application Developer will be a key contributor within the Application Development team, working closely with a Senior Cloud Architect and a Lead Application Developer to design, develop, test, deploy, and support a broad range of modern software solutions. This role focuses on building predominantly cloud‑hosted applications leveraging the Microsoft .NET ecosystem and Azure platform . Solutions may include web applications, agentic and AI‑enabled applications, APIs, serverless function apps, integration services, and event‑driven systems. The ideal candidate is a hands‑on developer who enjoys solving complex problems, learning new technologies, and collaborating across technical and business teams. While not a strict requirement, exposure to AI‑assisted and AI‑driven development —including working with large language models (LLMs) and modern developer tooling—is highly valued.

RESPONSIBILITIES

Design, develop, test, and maintain high‑quality software solutions using the Microsoft .NET stack and Azure cloud services. Build and enhance web applications, APIs, background services, serverless function apps, and event‑driven components in a cloud‑native environment. Collaborate with the Senior Cloud Architect and Lead Application Developer on solution design, architectural decisions, and implementation patterns. Participate in the full software development lifecycle, including requirements analysis, technical design, development, testing, deployment, and production support. Develop secure, scalable, and maintainable solutions following modern software engineering principles and best practices. Implement and consume RESTful APIs and integrate with internal and external systems using Azure integration services. Work with document and relational data stores, selecting appropriate data models and access patterns. Contribute to CI/CD pipelines, automated testing, and infrastructure‑aware development practices. Assist with troubleshooting, performance tuning, and operational support of production applications as needed. Produce clear technical documentation and contribute to shared development standards and patterns. Communicate effectively with technical and non‑technical stakeholders, ensuring alignment and shared understanding. Support innovation initiatives, including experimentation with emerging technologies and development approaches. This position may require occasional off‑hours support of critical production applications and limited travel, as business needs dictate. Perform other duties and participate in projects as assigned.
