We are looking for a Senior .NET Engineer to build high-quality solutions using .NET technologies, SQL Server, and cloud environments.

Beyond technical execution, we need a professional with the confidence and critical thinking to challenge the status quo. In this role, you won't just blindly close tickets; you will proactively investigate requirements, analyze workflows, identify root causes, and actively propose better ways of working.

Key Responsibilities

• Design, build, and maintain cloud-native solutions on the Azure platform, utilizing the Azure Portal and Azure DevOps to develop core services like Function Apps, Service Bus, Queues, Storage, and Durable Functions from scratch.

• Develop, maintain, and optimize applications using .NET (C#) and SQL Server.

• Write and optimize advanced SQL Server stored procedures to handle heavy application logic, prioritizing strong database proficiency over standard ORM frameworks like Entity Framework or Dapper.

• Review incoming tickets and existing systems to identify root causes, challenge requirements when necessary, and propose cleaner architectures or workflows.

• Design and implement scalable, maintainable, and efficient code.

• Collaborate with cross-functional teams to define, design, and ship new features.

• Write clean, efficient, and well-documented code following best practices.

• Drive technical discovery with high autonomy and proactivity. Given a lean documentation process where tickets start with minimal context, you will act as a technical anchor by investigating requirements, conducting scoping meetings with stakeholders, and clarifying objectives.

• Provide strong technical leadership and communication, sharing your ideas with confidence, justifying architectural decisions, and engaging in constructive technical debates.

• Manage multiple contexts and applications simultaneously, comfortably handling distinct tickets across different client applications and environments.

• Apply a deep understanding of Dependency Injection containers and architecture within the .NET Core ecosystem.

• Participate in code reviews, testing, and troubleshooting.

• Ensure application performance, quality, and responsiveness.

Requirements

• 5+ years of experience with .NET (C#) development (Senior level).

• Advanced SQL Server proficiency, with proven experience writing complex stored procedures, query optimization, and database design.

• Strong hands-on experience with the Azure platform, specifically with core services like Function Apps, Service Bus, Queues, Storage, and Durable Functions.

• Solid understanding of Database projects, including experience working with DACPAC files for database deployments.

• Deep conceptual and practical knowledge of how Dependency Injection containers work within .NET Core.

• Proven ability to operate with high autonomy and proactivity, with a track record of driving technical discovery and clarifying scope from minimal context or informal communication channels.

• Strong critical thinking skills and the confidence to voice technical opinions to stakeholders and stand up for engineering best practices.

• Excellent verbal and written communication skills.

• Strong problem-solving, analytical skills, and a highly developed attention to detail.

• Ability to successfully manage multiple contexts and support various client applications simultaneously.

• Experience working with Agile methodologies.

Nice to have

• Experience with legacy Microsoft technologies, specifically supporting legacy ASP.NET applications and assisting in their ongoing migration to modern .NET Core.

• Ability to create and manage CI/CD build pipelines using YAML.
