Role Purpose

The Senior Software Engineer - Sabio Applications will take technical ownership of the development and ongoing evolution of a Sabio application that integrates with Genesys Cloud for administration.

You will own development quality across the application, make practical engineering decisions and ensure releases can be deployed and operated safely in customer environments.

Why Join Us

• Take features from technical design through implementation, automated testing, release and post‑release support.
• Improve application performance, reliability, maintainability and operational visibility as the product evolves.
• Plan and deliver new application versions to existing customers, considering compatibility, deployment risk and service continuity.
• Diagnose and resolve complex issues across the UI, backend, real‑time communications, message processing, cache and AWS infrastructure.
• Maintain appropriate automated test coverage using Playwright and Jest, supported by peer review and disciplined source control.
• Provide clear estimates for development work and identify technical risks, dependencies and blockers early.
• Maintain technical documentation and contribute to engineering standards and reusable development patterns.
