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.
