Fullstack Developer (.NET)

Responsibilities:

• Design and implement full-stack features using C#/. NET Core (services, APIs) and React for web, with optional contributions to React Native for mobile platforms.
• Build clean, well-structured microservices following SOLID principles, Clean Architecture, and Domain-Driven Design (DDD) patterns with strong test coverage (unit, integration, and contract tests).
• Develop containerized applications using Docker, deploy to Azure Kubernetes Service (AKS), and participate in CI/CD pipeline improvements.
• Integrate with messaging platforms (Azure Service Bus, Event Grid) to build event-driven and asynchronous workflows for distributed systems.
• Design and optimize SQL Server queries, schemas, and indexes for transactional workloads; implement Cosmos DB data models for high-throughput, low-latency scenarios with appropriate partitioning and consistency models.
• Contribute to observability: structured logging, distributed tracing, metrics collection, and dashboards using Application Insights, Prometheus, or similar tools.
• Participate in on-call/incident rotation as needed, helping diagnose, resolve, and learn from production issues in a 24/7 platform.
• Collaborate with senior engineers, architects, and product partners to refine requirements, participate in design reviews, and deliver high-quality features.

Requirements:

• 5-8 years building production software with substantial full-stack work across backend services and frontend applications.
• Proven experience in distributed systems or high-throughput transactional platforms.
• Experience in fintech, trading, or other mission-critical domains is an advantage.
• Strong problem-solving skills, ability to debug complex systems, and comfort with production support responsibilities.
• Excellent communication and collaboration skills in distributed, Agile team environments.
• Proficiency in C# and. NET Core (6/7/8+), including dependency injection, async/await patterns, TPL, and REST API design best practices.
• Strong React experience with hooks, functional components, state management (Redux/Context API), TypeScript, and modern build tooling (Webpack, Vite).
• Hands-on experience with relational databases (SQL Server: indexing, query optimization, transactions) and at least one NoSQL store (Cosmos DB preferred: partitioning, consistency tuning).
• Experience with messaging systems (Azure Service Bus, Event Grid) and event-driven architecture patterns.
• Understanding of containerization (Docker) and Kubernetes/AKS basics: deployments, services, ConfigMaps, secrets, resource limits.
• Familiarity with CI/CD workflows (Azure Pipelines, GitHub Actions), Git-based development, feature toggles, and automated testing frameworks.
• Experience with API security (authentication, authorization, JWT, OAuth2) and secure coding practices.
• Knowledge of observability practices: structured logging, distributed tracing (Application Insights, OpenTelemetry), and metric-driven debugging.
