Senior .NET Developer

- Role Overview: We are seeking a high-caliber Senior .NET Developer with deep hands-on software engineering, robust solution design, and enterprise integration experience. In this role, you will architect and build scalable enterprise backend, implement resilient distributed systems, and champion engineering rigor through Specification-Driven Development (SDD) and modern AI-augmented engineering workflows. Key Responsibilities: - Enterprise Core Development: Design, develop, and maintain high-throughput, mission-critical backend solutions using C#, ASP.NET Core, and modern .NET run times (.NET 8/9/10). - Specification-Driven Development (SDD): Author, review, and rigorously adhere to OpenAPI/AsyncAPI contracts and technical specifications before system implementation begins. - Integration & API Architecture: Design robust RESTful APIs, gRPC services, and messaging layers to seamlessly connect modern platforms with legacy systems, databases, and third-party APIs. - Architectural Patterns: Apply Clean Architecture, Domain-Driven Design (DDD), Modular Monoliths, and Event-Driven/Microservice architectures where appropriate. - Resilient Distributed Systems: Implement fault-tolerant distributed solutions leveraging asynchronous message handling, distributed caching, circuit breakers, and retry policies. - Code Quality & Mentorship: Conduct rigorous technical reviews, enforce engineering standards, and actively mentor mid-level and junior developers - AI-Augmented Workflows: Champion AI-assisted engineering using GitHub Copilot, Cursor, Claude, and specialized AI coding agents to accelerate delivery velocity without sacrificing quality. - Quality & Security Governance: Ensure all authored and AI-assisted code meets strict benchmarks for security, performance, maintainability, and test coverage. - Telemetry & Observability: Instrument systems from the ground up with structured logging, distributed tracing, and metrics for end-to-end visibility. - - Team Growth: Participate in technical interviews and contribute directly to elevating technical standards across the engineering team. Requirements - Core .NET Mastery: 5+ years of professional backend software development experience with expert-level proficiency in C#, ASP.NET Core, and contemporary .NET runtimes. - Specification & Contract-First Design: Proven expertise with API-first and Specification-Driven Development (OpenAPI/Swagger, contract testing, schema-first design). - ORM & Data Access: In-depth working knowledge of Entity Framework Core (EF Core), Dapper, complex LINQ queries, raw SQL optimization, and migration workflows across SQL Server and/or PostgreSQL. - Design Principles & Architecture: Thorough command of Clean Code, SOLID design principles, GoF design patterns, DDD fundamentals, and distributed system concepts (eventual consistency, idempotent consumers). - Automated Testing: Practical experience designing test suites using xUnit or NUnit, mocking frameworks, and containerized testing harnesses (e.g., Testcontainers). - Security & Compliance: Comprehensive implementation of authentication and authorization protocols (OAuth2, OpenID Connect, JWT, RBAC/PBAC). Proactive API security hardening, input validation, and defensive mitigation against OWASP Top 10 vulnerabilities. Secure secrets handling and data protection in transit (TLS) and at rest. - Observability & SRE Baseline: Structured logging architecture (e.g., Serilog) with correlation and trace identifiers. Distributed telemetry collection using OpenTelemetry standards. Implementation of application health checks, Prometheus/Grafana metrics instrumentation, and APM diagnostic workflows. - Legacy & Enterprise Integrations: Practical experience integrating with legacy workloads, SOAP/XML services, enterprise service buses, and background workers. - DevOps & Containerization: Hands-on containerization with Docker, Git-based branching workflows, and automated CI/CD pipelines. PREFERRED QUALIFICATIONS & TECH RADAR - High-Performance & Runtimes: Exposure to .NET Aspire, Native AOT compilation, and high-performance, low-allocation C# programming - Distributed Messaging & Caching: Hands-on experience with RabbitMQ, Apache Kafka, and distributed in-memory caching solutions using Redis. - AI & Agent Workflows: Familiarity with Model Context Protocol (MCP), prompt engineering, or autonomous AI coding agent workflows in IDEs. - Infrastructure Awareness: Basic familiarity with containerized deployments on container platforms or cloud environments (e.g., Google Cloud, Huawei Cloud, or Kubernetes) is a plus (cloud vendor exp is not mandatory).
