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.
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
What You Bring
- Node.js
- TypeScript
- NestJS
- Express (secondary)
- PostgreSQL
- Prisma ORM
- Redis
- RabbitMQ
- JWT / OAuth
- REST APIs
- WebSockets
- Background Jobs
Non-Negotiables
- SaaS product development
- Multi-tenancy
- PostgreSQL optimization
- Query optimization
- Docker
- API security
- Payment gateway integration
- Third-party APIs
- Unit & integration testing
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
