What the Role Entails

Tencent RTC (trtc.io) runs on Tencent’s global real-time network, which covers 200+ countries and regions and serves 1B+ monthly active users, with transport latency under 300 ms. Our portfolio spans Conversational AI (Voice Agent), RTC, Chat, Live Streaming and Tencent Cloud Contact Center (TCCC). Together they let enterprises build human-like AI voice agents across apps, web and the phone network, including AI inbound and outbound calling at scale. We are growing our Singapore team to lead Voice AI adoption across Southeast Asia and India.

• Own Voice AI pre-sales end to end. Act as the technical lead with Sales on AI outbound and inbound calling, voice agents and contact center deals: discovery, solution design, sizing and cost modelling, RFP responses, PoCs and go-live.
• Design production-grade voice agent architectures. Combine TRTC Conversational AI and TCCC (SIP trunk / BYOC, numbers, IVR, AI outbound APIs) with customers’ choice of ASR, LLM and TTS (OpenAI-compatible, Azure, MiniMax and others), MCP or tool calling, and CRM or core-system integration. Design for low latency, natural interruptions (barge-in), smooth handoff to human agents and quality assurance, with agents that handle multilingual and code-switched conversations (e.g. English, Bahasa Indonesia, Malay, Thai, Vietnamese, Tagalog, Hindi and Mandarin).
• Build and demo. Turn customer use cases into live agents within days, such as collections, payment reminders, telesales, appointment confirmation, KYC, customer service, AI companions, tutoring and in-game NPCs. Use Agent Studio, the APIs and the SDKs to do it.
• Bring market insight back to the product team. Feed SEA-specific requirements (carrier conditions, local-language ASR/TTS quality, PDPA and financial-regulator compliance) and competitive intelligence on leading voice AI and CPaaS players into the product roadmap.
• Build our industry presence. Speak at industry events, run workshops and hackathons, and enable regional partners, SIs and ISVs to build on Tencent RTC and TCCC.
• Also support the core RTC portfolio. Support RTC, Chat and live-streaming opportunities across social, gaming, education and fintech.

Who We Look For

• 5+ years in solutions architecture, pre-sales or technical consulting, including 2+ years hands-on with voice AI, conversational AI, AI outbound calling or contact center (CCaaS/CPaaS) solutions.
• Solid understanding of the real-time voice agent pipeline: streaming ASR, LLM orchestration and prompting, streaming TTS, VAD and interruption handling, and end-to-end latency tuning.
• Working knowledge of telephony: SIP, SIP trunks, PSTN, codecs, IVR, and dialer modes (predictive or automated outbound).
• Able to build demos in Python or Node.js and to integrate REST APIs and webhooks.
• Professional fluency in English and Mandarin, as about 50% of the role involves working in Mandarin with our headquarters product and R&D teams in China.
• Bachelor’s degree or above in Computer Science, EE or a related field, or equivalent practical experience.

Nice to Have

• Voice AI deployments in banking, fintech or lending (collections), telco, insurance or e-commerce in SEA.
• Experience with WebRTC/RTC, live streaming or public cloud (Tencent Cloud, AWS, GCP, Azure).
• Background at a voice AI vendor, CCaaS/CPaaS provider or cloud provider.
