Senior Fullstack Developer

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 containerised 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 optimise 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 features with high quality
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 optimisation, 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.
Familiarity with CI/CD workflows (Azure Pipelines, GitHub Actions), Git-based development, feature toggles, and automated testing frameworks.
Experience with API security (authentication, authorisation, JWT, and OAuth2) and secure coding practices.
Knowledge of observability practices: structured logging, distributed tracing (Application Insights, OpenTelemetry), and metric-driven debugging.
