Senior .NET Developer (IoT)

We’re seeking a Senior Software Engineer to lead the design and development of the backend systems that power our connected device ecosystem. You’ll architect scalable, secure, and modular APIs and services enabling ** real-time communication **, ** state synchronization **, and ** cross-platform device interoperability **—with a strong focus on ** IoT and Matter standards **. This is a senior, hands-on engineering role for someone deeply passionate about building robust systems that bridge hardware, cloud, and mobile experiences.

Key Responsibilities:

• Design and develop high-performance backend services in C#.
• Architect cloud-agnostic solutions deployable on ** AWS **, ** GCP **, ** Azure **, or on-premises.
• Build and maintain REST APIs with a focus on performance and scalability.
• Implement **real-time event-driven systems **, including push notifications, web hooks, and messaging services.
• Design and optimize PostgreSQL and ** Redis** systems for relational, caching, and live data sync use cases.
• Ensure observability through Sentry or similar tools for monitoring and performance tracing.
• Implement strong **API security **(OAuth2/OIDC, JWT , rate limiting, input validation).
• Manage configuration synchronization and ** state consistency** between devices and cloud systems.
• Build and deploy containerized services using Docker and ** CI/CD pipelines **.
• Maintain exceptional **code quality **, ** SQL optimization **, and ** documentation standards **.

Requirements

• Bachelor's degree in Computer Science, Information Technology, or a related field.
• 8+ years of backend development experience using C#.
• Proven track record in **designing scalable, modular microservices **.
• Deep expertise in PostgreSQL and ** Redis** for real-time and relational data management. Preferably with ** MS SQL** experience.
• Extensive experience building REST APIs from schema to integration.
• Strong foundation in **API security **, ** authentication **, and ** authorization protocols **.
• Proficiency with **Docker **, ** CI/CD pipelines **, and ** DevOps workflows **.
• Experience with background job processing and ** event-driven systems **.
• Familiarity with cloud-agnostic design for multi-environment deployment.
• Experience with **event-driven architectures **(MQTT , Kafka, RabbitMQ, etc.).
• Excellent communication skills and collaborative mindset.
• Works with initiative.
• A great team player.

Preferred Qualifications (Bonus Points):

• Strongly preferred and highly desirable. You understand IoT architecture, device provisioning, state synchronization, and secure connectivity models.
• Experience with **background job frameworks **(e.g., Celery, Hangfire, or custom queue-based systems).
• Background in **telemetry **, ** analytics **, or ** device data pipelines **.
• Azure on-premises is highly desirable

Benefits

*   Competitive salary and benefits package.

*   Opportunity to work with a dynamic and innovative team.

*   Professional growth and development opportunities.
