Job Title

Senior Software Engineer – Voice Platform Department &

Summary

We are seeking a Senior Software Engineer to join our Voice Platform team, building high-performance, network-facing services that power real-time voice communications for Genesys Cloud contact centers worldwide.

This is an exciting opportunity for an experienced Java backend engineer who enjoys building reliable, scalable cloud services and wants to broaden their experience across networking, Linux, C, and real-time communications. Java will be the primary development language for this role, with engineers working on cloud backend services and distributed systems that support our global Voice Platform. You will also have opportunities to contribute to systems-level and network-facing components written in C, developing your knowledge of the lower levels of the voice technology stack.

You will own features end to end and help deliver highly available voice capabilities used by enterprise customers at global scale. Prior SIP/VoIP or contact-center experience is a plus, not a requirement. If you enjoy backend engineering, distributed systems, production ownership, and learning a specialized technical domain, this role is for you.

• Contribute to network-facing and systems-level components written in C , working alongside experienced engineers and developing deeper systems programming knowledge.
• Learn and apply SIP/VoIP and Genesys voice-platform concepts as part of day-to-day development.
• Investigate and resolve complex production issues spanning application, networking, cloud, and systems layers.
• Collaborate with Product, Architecture, DevOps, QA, Security, and Operations to turn requirements into reliable technical solutions.
• Follow and contribute to engineering practices covering architecture, code quality, CI/CD, automated testing, observability, monitoring, and production operations.
• Participate in design reviews, code reviews, and incident response, while sharing technical knowledge across the team.
• Continuously improve the performance, reliability, scalability, and maintainability of the services you own.

• Interest in developing or expanding skills in C and systems-level programming .
• Willingness to learn SIP/VoIP and real-time communications concepts.
