As a Staff .NET Developer at Rebtel you will serve as the technical guardian and principal individual contributor for the entire

Backend (BE) architecture and ecosystem. This role is crucial for ensuring the technical excellence, scalability, reliability, and

security of all backend systems that power our core products and services. The Staff Software Engineer will operate at a high

level of abstraction, influencing engineering practices across multiple teams while remaining hands-on in critical areas.

You’ll be actively involved in architectural decisions, contribute to technical discussions, and inspire your team to deliver

clean, robust code.

• Lead the design, development, and deployment of complex, high-throughput backend services and APIs, ensuring best-in-class

performance and maintainability.

• This includes planning for future growth, anticipating technological shifts, and driving the adoption of new technologies and

patterns to maintain a competitive edge.

• Act as the primary architect for major system initiatives, defining microservices boundaries, data models, integration

patterns, and deployment strategies.

• Influence engineering standards and best practices for testing, performance tuning, and security across different development

teams.

• Exceptional and proven proficiency in the .NET area, including extensive experience with C#, .NET Core/8+, and related

frameworks (e.g., ASP. NET Core, Entity Framework Core).

• Demonstrable architecting skills with a strong background in designing and implementing large-scale, distributed systems (e.g.,

microservices, event-driven architectures, serverless).

• Extensive experience with at least one major cloud platform (AWS, Azure, or GCP) and related services (e.g., managed databases,

message queues, containerization).

• System-Level Thinking: Ability to decompose complex problems into manageable components and evaluate trade-offs between

different technical solutions (e.g., speed vs. stability, buy vs. build).

• Excellent verbal and written communication skills, with the ability to present complex technical ideas clearly to both

technical and non-technical stakeholders, driving consensus on critical architectural decisions.
