We’re a growing SaaS company building modern, scalable web applications used by customers who expect things to just work.

Responsibilities

• Designing and building back-end services using C# and ASP.NET (REST APIs)
• Working with Entity Framework Core to design and optimize data access
• Building and integrating message-based systems (event-driven, async workflows, etc.)
• Helping shape system architecture with scalability, performance, and reliability in mind
• Collaborating closely with product and front-end teams to deliver real features, not just tickets
• Improving existing systems — refactoring, optimizing, and making things simpler

Your profile

• Strong experience with C# / .NET CORE + in production environments
• Solid understanding of ASP.NET Core and RESTful API design
• Hands‑on experience with Entity Framework Core
• Experience working with message brokers (e.g. RabbitMQ, Azure Service Bus, Kafka, etc.)
• A good grasp of scalable system design and modern back‑end patterns
• Someone who cares about code quality, maintainability, and performance

Nice to have

• Experience working in SaaS products
• Cloud experience (Azure, AWS, or similar)
• Familiarity with CI/CD, containers, or microservices
• An interest in keeping up with modern .NET and back-end best practices
• You’ll work on cutting-edge tech , not legacy maintenance
• Real influence over architecture and technical decisions
• A team that values clean solutions over quick hacks
• Room to grow as the product and company scale
