Forward Deployed Engineer, Israel

About the Position

We are looking for a Forward Deployed Engineer to join our team in Tel Aviv, Israel. You will be part of a local Enterprise Sales Pod, working closely with an Enterprise Account Executive (AE) to build and ship production systems on Telnyx's global network for enterprise customers. This role is about creating real, scalable solutions, not just demoing products.

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 and deploy LiteLLM as the model gateway.
• Instrument and govern LLM usage through the gateway for cost tracking, caching, logging, and observability.
• Design model routing strategies for real-time voice workloads.
• Make the build-vs-buy case between self-hosted open-weight models and hosted frontier APIs.
• Adapt models to customer domains, including 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 and 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.

Requirements

• CS degree or equivalent experience.
• 3+ years building and shipping production software.
• Proficiency in multiple languages: Python, Node.js/TypeScript, Go.
• Practical understanding of production model issues: provider rate limits, timeout and retry behavior, streaming, token accounting, and failure modes.
• Comfortable deploying containerized services on Kubernetes.
• Experience with observability tools: Prometheus + Grafana, OpenTelemetry, Graylog, ELK, or equivalent.
• High-concurrency experience: Kafka, message queues, or event streams.
• Experience building APIs from scratch: OpenAPI spec, REST/GraphQL design, auth, rate limiting, versioning, idempotency.
• Event-driven thinking and cloud-native instincts.
• Exposure to SIP, WebRTC, or real-time voice/messaging systems.
• Self-sufficient by default: read the code and the docs, ask the customer, and make sound engineering judgment calls on your own.
• Customer-facing engineering experience: run discovery with customer engineers and present to their executives.
• Ability to translate "it's not working" into root cause.
• Comfortable working on customer sites and in high-stakes technical conversations.
• Excellent written and verbal communication in English and Hebrew.
• Based in Tel Aviv, or willing to relocate - this is a hybrid role with travel across Israel.
• Legally authorized to work in Israel, or eligible for sponsorship.

Nice to Have

• Experience with AI voice assistants, STT/TTS, or LLM-based conversational systems.
• Building eval sets for a specific domain.
• Hands-on production experience with an LLM gateway.
• Familiarity with the open-weight model landscape and the trade-offs between regional and multilingual models.
• Experience with an inference serving engine behind the gateway.
• SQL proficiency.
• ETL and data wrangling experience.
• CI/CD pipeline design and automation.
• Background in telecom, CPaaS, or high-growth SaaS.
• Experience with sovereign or on-prem cloud deployments and Israeli regulatory frameworks.
• Security mindset.

We Offer

• Opportunity to work with a leading industry innovator in global connectivity.
• Be part of a team shaping a new era of seamless interconnection between people, devices, and applications.
• Continuous learning and growth opportunities.
• Competitive compensation package.
