Engineer

• Deliver, configure, and deploy contact centre and enterprise telephony solutions, including SIP-based voice architecture, PBX, IVR, and CCaaS platforms, across customer environments.
• Design, test, and implement scalable and secure voice solutions, translating customer requirements into low-level designs and production-ready deployments.
• Own implementation workstreams across multiple projects, coordinating with internal teams and customers through build, test, and user acceptance phases.
• Provide advanced troubleshooting and incident support for production voice platforms, including root cause analysis and remediation of SIP and media-related issues.
• Act as a subject-matter expert on SIP servers, SIP trunking, telco interconnects, and carrier connectivity within customer and internal platforms.
• Configure and support integrations between contact centre platforms and enterprise systems such as CRM, identity services (SSO/AD), and related tooling, primarily at a system and configuration level.
• Support and troubleshoot browser-based communication use cases, including WebRTC signalling, media flow, and real-time voice delivery.
• Read, understand, and reason about scripts and automation used by engineering teams to support delivery, troubleshooting, and operational efficiency.
• Work closely with other Services Engineers, platform engineers, and AI teams to enable end-to-end delivery, including routing and managing audio streams for AI-driven use cases.
• Stay current with evolving voice, CCaaS, and WebRTC technologies, proactively learning and applying new approaches to improve delivery speed and quality.

• Legacy modernisation: Rewrite and migrate existing backend services (currently implemented in TypeScript) into Go and newer backend architectures.
• Cloud-native collaboration: Develop cloud-native backend systems on AWS, working closely with the infrastructure team to clearly articulate service requirements and operational needs.
• Data & persistence: Design and work with SQL-based data models, ensuring performance, correctness, and alignment with real product usage; contribute to NoSQL usage where appropriate.
• Product-facing backend work: Support communication and notification services across WhatsApp, SMS, email, and voice channels, handling communication metadata at scale.
• Production ownership: Own backend services in production, including reliability, performance, observability, and continuous improvement.
• Technical quality: Write clean, maintainable, and well-documented backend code, and participate actively in code reviews and technical design discussions.
• Ownership & initiative: Take initiative and drive backend problems through to solutions independently, collaborating effectively with peers across engineering.
