Role Overview

We are seeking a strong Full Stack Developer with hands on experience in building scalable, secure, high performance applications using .NET, React.js or React Native, microservices, messaging platforms, containers, MQTT brokers, and gRPC. The ideal candidate will have experience developing applications that require low latency, high throughput, reliable message processing, and efficient service to service communication.

This role will be responsible for designing and developing full stack solutions across backend services, user interfaces, APIs, event driven workflows, and containerized deployments. The candidate should be comfortable working in distributed systems where performance, resilience, scalability, and maintainability are critical.

Key Responsibilities

• Full Stack Application Development
  • Design, develop, and maintain full stack applications using .NET and React.js or React Native.
  • Build responsive, maintainable, and user friendly frontend applications with clean component based architecture.
  • Develop backend services, APIs, and business logic that support scalable and high volume application workloads.
• .NET API and Microservices Engineering
  • Design and develop REST APIs, gRPC services, and microservices using .NET Core / ASP.NET Core.
  • Implement service boundaries, API contracts, authentication, authorization, validation, error handling, and observability.
  • Build distributed backend services with a focus on reliability, maintainability, and performance.
• Messaging and Event Driven Architecture
  • Develop solutions using Kafka, MQ based messaging systems, and MQTT brokers.
  • Implement publish subscribe patterns, queue based processing, retries, dead letter handling, message ordering, and idempotency.
  • Support real time and near real time data flows for high volume message processing and telemetry workloads.
• Performance and Scalability
  • Design and optimize applications for low latency and high throughput processing.
  • Identify and resolve bottlenecks across APIs, services, databases, messaging layers, containers, and frontend applications.
  • Apply caching, asynchronous processing, connection pooling, concurrency control, load balancing, and performance tuning techniques.
• Containers and Deployment
  • Containerize applications and services using Docker.
  • Work with DevOps teams to support CI/CD pipelines, environment configuration, logging, monitoring, and automated deployments.
  • Support Kubernetes based deployment environments where applicable.
• Collaboration and Engineering Practices
  • Collaborate with architects, product owners, QA engineers, DevOps engineers, and business stakeholders to deliver features end to end.
  • Participate in solution design discussions, code reviews, sprint planning, and technical decision making.
  • Write clean, secure, testable, and well documented code following engineering best practices.

Required Qualifications

• Technical Skills
  • 6+ years of professional software development experience, with strong hands on full stack development exposure.
  • Strong experience in .NET Core / ASP.NET Core, C#, object oriented programming, REST APIs, and backend service development.
  • Strong experience with React.js and working knowledge of React Native for mobile or cross platform application development.
  • Solid understanding of microservices architecture, distributed systems, API design, and service to service communication.
  • Hands on experience with Kafka or MQ based messaging platforms.
  • Experience working with MQTT brokers for device, IoT, telemetry, or real time communication use cases.
  • Experience building gRPC based services or integrating applications using gRPC.
  • Hands on experience with Docker containers and containerized application development.
  • Proven experience developing applications that require low latency, high throughput, high concurrency, or real time processing.
  • Good understanding of relational databases, data access patterns, query optimization, caching, and transaction handling.
  • Knowledge of secure API design, authentication, authorization, JWT, OAuth2, input validation, and API rate limiting.
• Other Skills
  • Strong problem solving, debugging, and performance analysis skills.
  • Ability to understand complex system behavior across frontend, backend, messaging, and infrastructure layers.
  • Strong communication skills for collaboration with distributed teams.
  • Ability to work in agile environments and take ownership of technical delivery.

Preferred Qualifications

• Experience with Kubernetes in production or non production environments.
• Experience with cloud platforms such as AWS, Azure, or GCP.
• Experience with observability tools such as Prometheus, Grafana, ELK, Datadog, Dynatrace, or Application Insights.
• Experience with Redis or other distributed caching technologies.
• Experience with SQL Server, PostgreSQL, MongoDB, or other SQL and NoSQL databases.
• Experience with CI/CD tools such as Azure DevOps, GitHub Actions, Jenkins, GitLab CI, or similar platforms.
• Prior experience in IoT platforms, connected devices, telemetry systems, trading systems, logistics platforms, or other high volume application environments.
• Familiarity with domain driven design, event sourcing, CQRS, or modern distributed application design patterns.

Education
