About the role

Remote, customer-facing role based in São Paulo, embedding with enterprise customers across Latin America to architect and deploy production systems on Telnyx's global network, including open-weight LLM deployments and LiteLLM gateway in customer environments.

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), and WebRTC
  • Deploy and operate open-weight LLMs such as Llama, Qwen, Mistral, DeepSeek, and gpt-oss in customer-controlled cloud, on-premises, and air-gapped environments
  • Deploy and operate LiteLLM as the model gateway in customer environments, providing a unified OpenAI-compatible interface across self-hosted models and hosted providers, with routing, load balancing, retries and fallbacks, rate limits, and per-team virtual keys
  • Instrument and govern LLM usage through cost tracking and budgets, caching, logging and observability using OpenTelemetry, Langfuse, or similar tools, and guardrails
  • Design model-routing strategies for real-time voice workloads, balancing latency, cost, reliability, and Spanish- or Portuguese-language quality
  • Make the build-vs-buy case between self-hosted open-weight models and hosted frontier APIs, while keeping customer application code portable across both
  • Adapt models to customer domains through prompt and RAG pipelines, LoRA/QLoRA fine-tuning, and evaluation harnesses for Spanish, Portuguese, and multilingual use cases
  • Lead POCs, pilots, and production launches from whiteboard to go-live
  • Own customer outcomes and remain engaged until the solution is live and stable
  • Collaborate directly with Product and Engineering to shape the roadmap based on field insights from the Latin American market
  • Create clear technical documentation, runbooks, and maintainable solutions for handoff in English and, where needed, Spanish or Portuguese
  • Troubleshoot and resolve complex integration issues alongside customer teams
  • Help customers address applicable privacy, security, telecommunications, and data-residency requirements; including Brazil's LGPD

Qualifications

  • CS degree or equivalent experience
  • 3+ years building software or doing technical consulting
  • Proficiency in multiple languages such as Python, Node.js, and Go
  • Hands-on experience running LiteLLM or a comparable LLM gateway in production
  • Practical understanding of production model-gateway challenges (rate limits, timeouts, retries, streaming, cost attribution, concurrency issues)
  • Comfort deploying containerized services on Kubernetes with secrets management, observability, and upgrades
  • Strong API fluency, event-driven thinking, and cloud-native instincts
  • Exposure to SIP, WebRTC, VoIP, or real-time voice and messaging systems
  • Ability to translate issues into root cause
  • Comfort working directly with customers in high-stakes conversations
  • Professional fluency in Spanish or Portuguese
  • Professional working proficiency in English
  • Based in or near Bogotá, Mexico City, or São Paulo, authorized to work in the applicable country
  • Willingness to travel approximately 10–30% across Latin America
