Job details:

Role Overview

We are looking for a Video Conferencing Product Developer who can build a scalable, secure, real-time video communication product (similar in core capability to Google Meet / Zoom) from scratch. This is not a design-heavy role. This role is about engineering depth, architecture clarity, and execution. You will own the end-to-end development of the product- from real-time communication logic to backend scalability and performance optimization.

Key Responsibilities

1. Product Development (Core)

• Build a real-time video conferencing system with:

• 1:1 and group video calls

• Audio & video streaming

• Screen sharing

• Chat

• Call join via link / room-based system

• Implement low-latency, high-quality video & audio transmission

• Handle participant join/leave, mute/unmute, camera on/off, and reconnections

2. Real-Time Communication

• Work with WebRTC (or equivalent real-time protocols)

• Manage signaling servers and peer connections

• Optimize bandwidth usage and media performance

3. Backend & Infrastructure

• Design backend for:

• User/session management

• Meeting rooms & access control

• Authentication & authorization

• Ensure scalability for multiple concurrent users

• Integrate TURN/STUN servers where required

• Handle cloud deployment and monitoring

4. Security & Reliability

• Implement secure communication (encryption, access control)

• Prevent unauthorized access to meetings

• Ensure stability under high load

• Handle edge cases like network drops and reconnections

5. Ownership & Problem Solving

• Make architectural decisions independently

• Debug performance issues (latency, packet loss, jitter)

• Continuously improve reliability and user experience

Tech Stack (Flexible, but expectations clear)

Frontend

• JavaScript / TypeScript

• React / Vue / equivalent

• WebRTC integration

Backend

• Node.js / Python / Go / Java (any strong backend language)

• WebSockets / Socket.io / similar real-time messaging

• REST / GraphQL APIs

Media & Infra

• WebRTC

• STUN / TURN

• Cloud services (AWS / GCP / Azure)

• Docker / basic DevOps knowledge preferred

⸻

Required Skills & Experience

• Strong understanding of real-time systems

• Hands-on experience with WebRTC or live streaming

• Ability to design systems for scale and reliability

• Clear understanding of networking fundamentals

• Experience building production-grade applications

• Can work independently and take full ownership

⸻

Nice to Have

• Experience building video, audio, or streaming platforms

• Knowledge of SFU/MCU architectures

• Experience with mobile video conferencing

• Performance tuning and monitoring experience

⸻

What We’re Really Evaluating

• Can you think like a product engineer, not just a coder?

• Can you build something usable, stable, and scalable?

• Do you understand why things break in real-time systems?

⸻

Outcome Expectation

By the end of the engagement, there should be:

• A working video conferencing product

• Clear architecture documentation

• Scalable and secure implementation

• Code that can be extended into a full product
