Job Title: Senior Backend Engineer (IoT / High-Scale Systems)

Location: Mumbai - Onsite

Experience: 6+ years

About the Role

We are looking for a highly skilled Senior Backend Engineer to design, build, and scale backend systems powering large-scale IoT platforms. You will work on systems that ingest, process, and analyze high-throughput data streams from distributed devices such as solar installations or other IoT-enabled infrastructure.

Key Responsibilities

• Design and develop scalable backend services for IoT platforms handling millions of device events.
• Build and maintain high-throughput data ingestion pipelines for real-time and batch processing.
• Work with time-series data for monitoring, analytics, and reporting use cases.
• Architect reliable messaging systems using protocols like MQTT and queueing systems.
• Optimize systems for performance, scalability, and fault tolerance.
• Collaborate with hardware, firmware, and frontend teams to ensure seamless data flow.
• Implement robust monitoring, logging, and alerting systems.
• Ensure data integrity, security, and compliance across distributed systems.

Required Skills & Experience

• Strong experience in backend development using Node.js with TypeScript.
• Hands-on experience building systems for IoT products at scale (solar, energy, or similar domains preferred).
• Deep understanding of messaging and streaming systems:
• MQTT
• Amazon IOT core
• Amazon SQS and SNS
• RabbitMQ
• Experience working in high-throughput, low-latency environments.
• Expertise in handling time-series data (e.g., using InfluxDB, TimescaleDB, or similar).
• Solid understanding of distributed systems, concurrency, and system design.
• Experience with cloud platforms (AWS or GCP).
• Strong debugging, performance tuning, and problem-solving skills.

Good to Have

• Experience in renewable energy domains (solar, EV, smart grids, etc.).
• Knowledge of stream processing frameworks (Kafka, Flink, Spark Streaming).
• Experience with edge computing or device-side integrations.
• Understanding of data pipelines and analytics platforms.
• Familiarity with containerization and orchestration (Docker, Kubernetes).

What We Offer

• Opportunity to work on cutting-edge IoT and energy-tech solutions.
• High ownership and impact on system architecture and scalability.
• Collaborative and fast-paced work environment.

Who You Are

• Passionate about building scalable systems that solve real-world problems.
• Comfortable working with ambiguity and complex distributed architectures.
• Strong communicator and team player.
