Enterprise FDE: AI, Telephony & Cloud Architect

telnyx54; Hong Kong; On-site; HKD 900,000 - 1,500,000; Full time

Job summary

Telnyx is building a local Enterprise Sales Pod in Hong Kong—one AE and one Forward Deployed Engineer (FDE)—working together to build a Telnyx enterprise business in your market. You'll embed directly with enterprise customers to architect and ship production systems on Telnyx's global network - voice, messaging, AI, and wireless.

This isn't about demoing products. It's about building real solutions that work at scale.

Responsibilities

• Embed with enterprise customers to understand their communications workflows, AI use cases, and integration challenges firsthand
• Build and deploy custom implementations: AI Voice Assistants, Telnyx APIs (Voice, Messaging, Fax, Wireless), WebRTC
• Run open-weight LLMs in customer environments - consume GLM, Kimi, DeepSeek, Qwen, and MiniMax through Telnyx Inference (OpenAI-compatible API; there's no model infrastructure for you to run), or deploy self-hosted stacks (Llama, Mistral, and region-specific models like CKIP-LLO, FlagAlpha, or other Cantonese/Chinese-language sovereign models) behind your own serving engine when air-gapped or sovereign-cloud requirements demand it
• Deploy and operate LiteLLM as the model gateway in customer environments: a unified OpenAI-compatible interface across self-hosted open-weight models and hosted providers, with routing, load balancing, retries and fallbacks, rate limits, and per-team virtual keys
• Instrument and govern LLM usage through the gateway - cost tracking and budgets, caching, logging and observability (OpenTelemetry, Langfuse, or similar), and guardrails - so customers can see and control what their AI workloads are doing
• Wire production observability for everything you ship - metrics, logs, traces, dashboards, and alerting (e.g. Prometheus + Grafana for metrics, OpenTelemetry for traces, Graylog or ELK for logs - or the customer's existing stack) - so you and the customer's ops team both know what "healthy" looks like and what pages whom when it isn't
• Design model routing strategies for real-time voice workloads, balancing latency, cost, and quality, with sane fallback behavior when a provider degrades
• Make the build-vs-buy case between self-hosted open-weight models and hosted frontier APIs, and keep the customer's application code portable across both
• Adapt models to customer domains: prompt and RAG pipelines and evaluation harnesses for English, Cantonese, and Mandarin language use cases and Hong Kong/APAC-specific regulatory environments (PDPO, data localization, Mainland China cross-border data transfer)
• Lead POCs, pilots, and production launches from whiteboard to go-live
• Own customer outcomes - stay engaged until the solution is live and stable
• Collaborate directly with Product and Engineering to shape the roadmap based on field
