Build the engine room of an enterprise Fleet & Transport ERP.

Location: Mumbai

Experience: 58 Years

Work Mode: Onsite

Type: Full-Time

If you enjoy solving hard backend problems - multi-tenancy, scale, security - this is your build.

1. About The Role

We're looking for a Senior Backend Developer to build the core modules of an enterprise-grade Fleet/Transport ERP running on a multi-tenant SaaS architecture. You'll work close to the metal of the system - APIs, data models, integrations, security - on a product enterprise customers depend on daily.

2. What You'll Own

• Develop enterprise-grade backend modules for a Fleet/Transport ERP platform
• Design and build robust, secure REST APIs and WebSocket-based real-time features
• Own PostgreSQL data modeling, query optimization, and performance tuning
• Implement authentication, authorization (JWT/OAuth), and API security best practices
• Integrate payment gateways and third-party APIs cleanly and reliably
• Build and maintain background jobs and asynchronous processing pipelines
• Write unit and integration tests as a habit, not an obligation

5. What Success Looks Like

• APIs you build are fast, secure, and simple for the frontend team to consume
• Data model decisions hold up as the platform scales across tenants
• Bugs caught in testing, not in production
• You're the person the team turns to for a hard backend problem
