Senior .NET Developer (temporary contract)

Job Description

About you
You're looking for a challenge where you can take ownership of critical backend services within a large-scale enterprise integration platform. You will design, build, and maintain event-driven, cloud-native solutions on Microsoft Azure that unify multiple business verticals into a single, scalable integration layer.

Note: This role operates under a 6-month contractor model.

You bring to Applaudo the following competencies:

• Bachelor’s Degree in Computer Science, Software Engineering, Computer Engineering, or a related field is desired, or equivalent professional experience.
• 8+ years of professional experience in software development, with a proven track record delivering complex backend solutions using the .NET ecosystem (C#, .NET 6/8).
• Solid, hands-on experience with Azure Service Bus and Azure Functions for building event-driven, serverless architectures.
• Experience with API Management and observability/APM tools such as Application Insights, Datadog, or New Relic for monitoring and troubleshooting in distributed environments.
• Experience designing, building, and maintaining robust, scalable RESTful APIs.
• Solid working knowledge of Domain-Driven Design (DDD) principles and enterprise integration patterns.
• Strong understanding of SOLID principles, design patterns, and unit/integration testing (TDD experience is a plus).
• Comfortable working in a shared-ownership architecture model, contributing to design decisions and technical strategy alongside senior peers, not just executing predefined designs.
• Comfortable working with AI-assisted development tools (Copilot, Claude, ChatGPT, Cursor, or similar) as part of daily workflow.
• Excellent communication skills in English, required to work effectively with our US-based team and stakeholders, and to clearly translate technical work into business terms.

You will be accountable for the following responsibilities:

• Design, develop, and own features within the core enterprise integration layer, from technical design to deployment and monitoring.
• Implement event-driven solutions using Azure Service Bus and Azure Functions, aligned with the broader integration architecture.
• Collaborate closely with the Principal Architect, tech leads, and other developers to deliver consistent, scalable solutions across business verticals.
• Take full ownership of assigned tasks, from planning through delivery, with minimal need for oversight.
• Communicate clearly and proactively with both technical and non-technical stakeholders on progress, blockers, and technical decisions.
• Champion code quality, testing, and CI/CD best practices; actively participate in code reviews.
• Troubleshoot and resolve complex issues in a distributed, cloud-based environment using Application Insights or equivalent APM tooling.

Qualifications

• Proficiency in C# and .NET 6/8 (.NET Core).
• Hands-on experience with Azure Service Bus, Azure Functions, API Management, Application Insights.
• Active use of AI tools in day-to-day development workflow.
