Senior Software Engineer Backend (.NET Stack)

ITGoals is a dynamic and innovative company committed to driving growth and delivering exceptional digital solutions. We pride ourselves on fostering a collaborative and inclusive work environment where creativity and technical excellence thrive.

Job Description

As a Senior Software Engineer Backend (.NET Stack) at ITGoals, you will design, build, and maintain backend services in the .NET ecosystem with a strong focus on performance, security, and scalability. You’ll work closely with cross-functional teams to deliver reliable APIs and services, contribute to architecture decisions, and help raise engineering standards through testing, reviews, and mentorship.

Key Responsibilities

• Design and develop RESTful APIs and backend services using .NET Core and C# to support core business operations.
• Own backend logic end-to-end: requirements clarification, implementation, testing, deployment support, and ongoing improvements.
• Optimize database performance by writing efficient SQL queries, tuning indexes, and improving data access patterns.
• Work with SQL Server and Entity Framework to model data, manage migrations, and ensure data integrity and consistency.
• Collaborate with frontend and mobile teams to define API contracts, ensure seamless integration, and troubleshoot cross-system issues.
• Implement and enforce API security best practices (authentication/authorization, secure data handling, rate limiting, and OWASP-aligned protections).
• Use caching and message queues where appropriate to improve performance, resilience, and throughput.
• Participate in code reviews, provide constructive feedback, and help maintain a clean, maintainable codebase.
• Write and maintain unit tests and contribute to overall test strategy and CI/CD quality gates.
• Mentor junior developers and contribute to system design and architecture discussions (including microservices and service boundaries).
• Support production health through debugging, monitoring, incident response, and continuous reliability improvements.

Required Skills & Qualifications

• BSc in Computer Science, Engineering, or a related field.
• 5+ years of backend development experience with .NET Core and C#.
• Strong experience with SQL Server, query optimization, and relational data modeling.
• Hands-on experience with Entity Framework (or similar ORM) and solid understanding of data access patterns.
• Strong understanding of RESTful API design and API security (authentication/authorization, secure coding practices).
• Experience with message queues (e.g., RabbitMQ, Azure Service Bus, Kafka) and asynchronous processing patterns.
• Experience with caching strategies and tools (e.g., Redis, in-memory caching) to improve performance.
• Exposure to microservices architecture and distributed systems fundamentals (resilience, observability, versioning, backward compatibility).
• Familiarity with cloud environments such as Azure and/or AWS.
• Comfortable working with Git, collaborative workflows, and participating in code reviews.
• Strong problem-solving skills, ownership mindset, and ability to communicate clearly in a cross-functional environment.

Nice to Have

• Familiarity with API gateway solutions (Software AG is a plus).
• Experience with containerization and orchestration (Docker, Kubernetes).
• Experience with observability tooling (logging, metrics, tracing) and production monitoring practices.
• Experience designing versioned APIs and maintaining backward compatibility for external consumers.

What Success Looks Like

• You deliver secure, reliable, and well-documented APIs that are easy for other teams to integrate with.
• You proactively improve performance and scalability through better data access patterns, caching, and asynchronous processing.
• You raise code quality through thoughtful reviews, testing practices, and pragmatic engineering standards.
• You contribute to architecture decisions and help the team evolve toward maintainable, scalable service design.
• You support and mentor teammates, helping the backend team execute consistently and confidently.

Additional Information

We’re looking for a motivated engineer who thrives in a collaborative environment and enjoys building dependable backend systems. If you care about clean architecture, secure APIs, and scalable services—and you like mentoring others while staying hands-on—you’ll feel at home at ITGoals.
