What will you do?
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.
Responsibilities and Tasks:
Lead the design, development, and deployment of complex, high-throughput backend services and APIs, ensuring best-in-class performance and maintainability.
Drive architectural decisions and serve as the ultimate technical escalation point for BE-related challenges.
Establish and articulate a clear, ambitious long-term vision and technical roadmap for the evolution of the BE systems.
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.
Proactively identify and resolve technical debt and architectural risks before they impact the business.
Mentor engineers, elevating the technical expertise and quality of engineering output across the organization.
Influence engineering standards and best practices for testing, performance tuning, and security across different development teams.
Requirements:
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).
Must demonstrate the ability to architect and build high-performance, fault-tolerant systems using the .NET stack.
Demonstrable architecting skills with a strong background in designing and implementing large-scale, distributed systems (e.g., microservices, event-driven architectures, serverless).
Expert knowledge of design patterns, domain-driven design (DDD), and SOLID principles.
Extensive experience with at least one major cloud platform (AWS, Azure, or GCP) and related services (e.g., managed databases, message queues, containerization).
Deep understanding of various database technologies (SQL and NoSQL) and data modeling best practices for scalable applications.
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.
