About OneIOT

OneIOT is a Hyderabad-based, AI-native IoT software company building fully customized platforms rather than template software. Our modular, Lego-style architecture allows us to deliver enterprise-grade solutions in weeks rather than months, across climate monitoring, asset tracking, and smart city systems, for customers across India, USA, and Europe.

As a fast-paced startup, we care more about outcomes than fixed hours — we look for people who take ownership of their work and see it through, rather than clock-watch. We value ownership and autonomy and are looking for a Backend Engineer with a strong interest in building scalable systems using Golang. The role involves designing, developing, and optimizing the APIs and data pipelines that power our IoT and data-driven platforms.

Responsibilities

• Develop and maintain high-performance backend services using Golang
• Build REST and gRPC APIs for large-scale data systems
• Optimize PostgreSQL queries and database interactions
• Collaborate with frontend, DevOps, and product teams on end-to-end delivery
• Write clean, testable, and maintainable code following best practices
• Participate in design discussions, code reviews, and architecture improvements

Requirements

• 1–2 years of backend development experience
• Strong hands-on experience with Golang (concurrency, goroutines, channels)
• Solid understanding of PostgreSQL and microservices architecture
• Experience with Docker and message queues (Kafka/NATS preferred)
• Familiarity with Node.js or TypeScript is a plus
• Strong problem-solving mindset and sense of ownership

Preferred Qualifications

• Experience with Redis, Prometheus, Grafana, or Kubernetes
• Exposure to CI/CD workflows
• Prior experience in a startup or fast-paced product environment
