Application Developer

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.
