NodeJS Developer

About Us:

We are hiring for a pre seed funded startup called Zeromoblt (https://zeromoblt.com/), a high-agency Hyderabad-based startup revolutionizing student transportation with lean, intelligent tech stacks.

Our mission: architect world-class systems from scratch—fast, scalable, and algorithmically sharp—using Kotlin, React, AWS (EC2, IoT, IAM), Google Maps, and multi-cloud setups. Stealth mode operations mean you're building 0→1 products with founders, not fixing tickets.

What You'll Do

• Lead end-to-end ownership of complex systems: design, build, deploy, monitor, and iterate at scale.
• Architect high-performance backends in Kotlin (or JVM langs) that handle real-time routing and IoT data.
• Craft scalable React UIs that power ops dashboards and parent-facing apps.
• Drive cloud decisions across AWS, Azure/GCP—optimising costs for our bootstrap runway.
• Apply DSA/system design to solve hard problems like dynamic route optimization and predictive scaling.
• Shape the engineering roadmap: propose, prioritise, and ship features with founders.
• Mentor juniors while executing solo on high-impact bets—no layers, just results.

We're Looking For

• 3-6 years of hands-on engineering where you've owned and shipped production systems (prove it with code/stories).
• Elite CS fundamentals: advanced DSA, system design (distributed systems a must), design patterns.
• Mastery of Kotlin/Java + modern React; real AWS experience (EC2, IAM, CLI—you know our stack).
• Proven "leap-taker": startup grit, side projects, or open-source that screams hunger.
• Figure-it-out velocity: you thrive in chaos, learn our domain overnight, and deliver 10x faster than peers.

This Role Is Not For You If…

• You need structured roadmaps, PM hand-holding, or big-tech process.
• Comfort > impact: stable salary over equity upside and chaos.
• You've never worn all hats (dev, ops, product) in a resource-constrained environment.

Why Join Us

• Massive ownership: lead tech for 10k+ students, direct founder access, shape ZeroMoblt's scale.
• Flat, high-trust team: flexible Hyderabad/remote, no bureaucracy.
• Hungry culture: we hire hustlers scaling from 700 to 10k students your wins are visible daily.
• Hungry to Leap? Apply now!

Who You Are:

• You’ve built scalable, production-ready APIs in fast-paced environments, and are comfortable with the challenges that come with a growing startup.
• You understand event-driven architectures and have hands-on experience building real-time applications.
• You are fully capable of taking ownership of backend systems, from designing the database schema to writing efficient, maintainable code.
• You think beyond the code: optimizing performance, scalability, and security are as important as building new features.
• You’re comfortable troubleshooting complex issues, whether that’s API bottlenecks, database performance, or production issues.

Responsibilities:

• Design, implement, and manage a NestJS backend with a modular, scalable architecture that can easily handle real-time events and communication.
• Develop and maintain WebSocket services for real-time event-driven updates and ensure seamless communication across the system.
• Integrate RabbitMQ for reliable internal messaging, handling queues and ensuring event-driven workflows are efficient and fault-tolerant.
• Implement database management strategies using MongoDB, Redis, and Elasticsearch, ensuring efficient data handling, indexing, and optimization.
• Integrate with external APIs (JSON-RPC, XML-RPC, REST) to enhance system capabilities.
• Ensure high performance of the system by optimizing database queries, implementing caching strategies using Redis, and ensuring optimal indexing and data flow.
• Implement role-based authentication and authorization mechanisms using JWT, OAuth, and RBAC patterns within NestJS.
• Follow security best practices to ensure sensitive data is protected, credentials are stored securely, and the system is resilient to common vulnerabilities.
• Work collaboratively with cross-functional teams to ensure seamless integration between different services and technologies.

Must-Have Skills:

• Strong proficiency in Node.js and NestJS with TypeScript.
• Solid experience with MongoDB, Redis, and Elasticsearch for data storage and real-time data handling.
• In-depth knowledge of WebSockets and Socket.IO in NestJS Gateways, enabling real-time communication and updates.
• Experience with RabbitMQ for message queuing and asynchronous task handling.
• Strong understanding of authentication & authorization systems using JWT, OAuth, and RBAC (Role-Based Access Control).
• Expertise in optimizing APIs, including techniques for caching, improving database performance, and reducing latency.
• Familiar with API security best practices, including secure storage of credentials, encryption, and safeguarding sensitive data.

Key Skills:

• TypeScript, NestJS, WebSockets, Socket.io
• Redis, MongoDB, Elasticsearch, RabbitMQ
• API Optimization, JWT, OAuth, RBAC
• Real-time communication, Event-driven architecture
