About the role

Enterprise-focused engineering role embedded with enterprise customers in Tel Aviv to architect and ship production systems on Telnyx's global network, collaborating with an Enterprise AE to drive real production outcomes (AI contact centers, SOC/NOC agents, global communications, connected mobility, or enterprise inference) rather than demos.

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 to run), or deploy self-hosted stacks (Llama, Mistral, and region-specific models like Hebrew-adapted LLMs or other 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
  • 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)
  • 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 Hebrew and English language use cases and Israel-specific regulatory environments
  • 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 insights from Israel
  • Create clear technical documentation, runbooks, and maintainable solutions for handoff
  • Troubleshoot and resolve complex integration issues alongside customer teams

Qualifications

  • CS degree or equivalent experience
  • 3+ years building and shipping production software
  • Proficiency in Python, Node.js/TypeScript, Go
  • Practical understanding of production model breakage scenarios (rate limits, timeouts, cost attribution, concurrency failure modes)
  • Experience deploying containerized services on Kubernetes with secrets management, config, upgrades
  • Experience with observability tools (Prometheus + Grafana, OpenTelemetry, Graylog, ELK)
  • High-concurrency experience with Kafka, message queues, or event streams
  • API design experience (OpenAPI, REST/GraphQL, auth, rate limiting, versioning, idempotency)
  • Event-driven/cloud-native mindset
  • Exposure to SIP, WebRTC, or real-time voice/messaging systems
  • Self-sufficient, autonomous—able to read code/docs and operate with customer input
  • Customer-facing engineering experience (discovery and executive-facing communication)
  • Ability to diagnose root causes and translate issues into fixes
  • Comfort working on customer sites and in high-stakes technical conversations
  • Excellent written and verbal English and Hebrew communication
  • Based in Tel Aviv or willing to relocate; hybrid role with travel within Israel
  • Legally authorized to work in Israel or eligible for sponsorship
