Role Overview

We are looking for a hands-on Senior Telephony Engineer who actively writes production-grade code and has deep experience with Asterisk-based systems, Java backend development, and high-scale dialler platforms.

Key Responsibilities

This is NOT an architecture-only role — we need someone who can:

Write code
Debug real-time call issues
Build and optimize telephony flows end-to-end
Key Responsibilities (Hands-on Coding Focus)
Develop and maintain Asterisk dialplans, AGI scripts, and call flows
Build Java-based backend services for telephony control and orchestration
Implement and optimize predictive / preview / progressive diallers
Integrate telephony stack with:

Kafka

RabbitMQ

Write scalable code for call routing, retry logic, and queue handling
Work directly on SIP signalling, RTP flows, and debugging call issues
Handle real-time call events, CDR processing, and logging pipelines
Optimize systems for high concurrency (thousands of parallel calls)
Debug production issues like:

Call drops

Latency

One-way audio

SIP failures

Qualifications & Skills

Bachelor’s degree in Computer Engineering; Master’s is a plus.
Telephony (Core Requirement)
Strong hands-on experience with Asterisk
Deep knowledge of:

SIP / RTP / VoIP

Dialplans

AGI / AMI

Experience building or maintaining dialers (very important)
Backend Development
Strong coding skills in Java (Spring Boot preferred)
Experience building microservices / APIs
Comfortable writing high-performance, low-latency code
Messaging & Event Systems
Hands-on experience with:

Apache Kafka

RabbitMQ

Ability to implement event-driven systems
Scaling & Performance
Experience handling high call volumes (1000+ concurrent calls)

Understanding of:

Multi-threading
Queue management
Load handling

· Good to Have

Experience with predictive dialers
Exposure to WebRTC / real-time communication
Experience with Docker / Kubernetes
Understanding of TRAI / Indian telecom ecosystem
Experience with FreeSWITCH (bonus)

What We Are NOT Looking For

Pure solution architects who don’t code
People with only theoretical telecom knowledge
Candidates without real dialer / Asterisk production experience

What We Are Looking For

Someone who has:

Written real dialplans and backend code
Debugged live call issues
Worked on production telephony systems
A problem solver who can go deep into logs, packets, and code

Impact of the Role

You will directly contribute to building a high-scale telephony + AI voice platform, working on real-time systems that handle thousands of concurrent calls.

Pay: ₹2,000,000.00 - ₹3,000,000.00 per year

Benefits:

Health insurance
Paid sick time

Work Location: In person
