Job Description

We are looking for a Senior Programmable Voice Engineer to develop programmable voice capabilities, call control services, media processing, and API-driven communications infrastructure similar to Twilio and other CPaaS platforms. The role includes designing and building the voice platform powering next-generation customer experience solutions using technologies such as FreeSWITCH, Kamailio, SIP, WebRTC, Java, and Spring Boot. It suits a senior engineer who can move confidently between architecture, code, delivery risk, non-functional requirements, and client-facing technical discussions.

Responsibilities:

Design and develop programmable voice services, APIs, and call-control capabilities for enterprise-scale communications platforms.
Build and extend voice infrastructure using FreeSWITCH, Kamailio, SIP, RTP, WebRTC, and related technologies.
Design and develop backend services and communication APIs using Java and Spring Boot to expose voice capabilities to internal and external applications.
Implement call routing, session management, media handling, carrier integrations, and voice traffic processing solutions.
Design highly available, scalable systems capable of handling large volumes of real-time communications traffic.Troubleshoot complex signaling, media, telephony, and call-quality issues across distributed environments.
Integrate voice services with contact center, routing, digital engagement, CRM, identity, and reporting platforms.
Define non-functional requirements for availability, performance, concurrency, security, privacy, observability, disaster recovery, and supportability.
Review designs and code, identify technical risks, challenge assumptions, and drive pragmatic decisions that balance quality, time, and cost.
Establish engineering standards, reusable patterns, quality gates, documentation expectations, and technology adoption guidance.
Collaborate with client stakeholders, Product, Architecture, QA, DevOps, Security, Operations, and vendors to govern delivery and resolve critical technical issues.

Qualifications

8+ years of software engineering experience, including substantial ownership of architecture and technical delivery for distributed applications.
Deep hands-on expertise with FreeSWITCH and/or Kamailio, including call control, dial plans, media services, ESL, modules, and platform customization.
Experience building API-driven communication platforms, voice services, or CPaaS-style solutions.Strong knowledge of voice infrastructure and real-time communications, including SIP, RTP, WebRTC, session control, media handling, and telephony troubleshooting.
Expert-level hands-on experience with Java, Spring Boot, microservices, REST APIs, persistence, security, testing, and performance engineering.
Deep understanding of API-first design, event-driven architecture, messaging, distributed systems, and cloud-native engineering.
Experience with PostgreSQL or comparable relational databases, data modeling, integration data flows, and transactional design.
Hands-on experience with contact center or CX platforms and the operational concepts behind customer routing and engagement.
Excellent communication skills, including the ability to produce clear technical documentation and lead client-facing workshops.

Nice to Have

Experience with OpenSIPS, Asterisk, Twilio, SignalWire, or comparable communications platforms.
Experience building routing engines, IVR platforms, voice bots, or omnichannel engagement services.
Experience with Genesys, NICE, Five9, Amazon Connect, Cisco, Avaya, or comparable contact center platforms.
Familiarity with Kafka or RabbitMQ, Kubernetes, Jenkins, observability platforms, API gateways, and security architecture.
Practical experience with AI-assisted software development or AI-enabled solutions, including tools such as Claude or GitHub Copilot, is a plus.
