The Role
We're looking for a Forward Deployed Engineer to join our team in Riyadh. In this hybrid role, you'll embed directly with enterprise and public-sector customers across the Kingdom to architect and ship production systems on Telnyx's global network — voice, messaging, AI, and wireless — including self-hosted, open-weight LLM deployments that run inside customer environments. This isn't about demoing products; it's about building real solutions that work at scale.
This role would suit a technical professional who thrives at the intersection of engineering and customer success. You're equally comfortable debugging SIP traces as you are standing up a LiteLLM gateway with routing and failover across a customer's model providers, or leading a whiteboard session with a customer's engineering team. The ability to own outcomes from POC to production go-live is essential.
Saudi customers increasingly require Arabic-first conversational AI and in-Kingdom data residency, so a large part of this job is making open-weight models perform in production on infrastructure the customer controls. This is a customer-facing role conducted largely in Arabic — fluent spoken Gulf Arabic is a hard requirement.
This is a Riyadh-based role with 10–30% travel to customer sites for deployments, workshops, and escalations — primarily across the Kingdom (Riyadh, Jeddah, Dammam/Khobar, NEOM) with occasional travel elsewhere in the GCC.
Responsibilities
Embed with enterprise and government 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
Deploy and operate open-weight LLMs (Llama, Qwen, Mistral, DeepSeek, gpt-oss, and Arabic-first models such as ALLaM, Fanar, and Jais) in customer environments, including air-gapped and in-Kingdom sovereign cloud deployments
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
Design model routing strategies for real-time voice workloads, balancing latency, cost, and quality across Arabic-capable models, 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, LoRA/QLoRA fine-tuning, and evaluation harnesses for Arabic (including dialectal Arabic) and bilingual Arabic/English use cases
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 the Saudi and wider MENA market
Create clear technical documentation, runbooks, and maintainable solutions for handoff, in English and where needed in Arabic
Troubleshoot and resolve complex integration issues alongside customer teams
Work with customers to meet local regulatory and data-residency requirements (CST/CITC, SDAIA, NCA, and PDPL obligations)
What We Are Looking For
CS degree or equivalent experience
3+ years building software or doing technical consulting
Proficiency in multiple languages: Python, Node.js, Go — you're more dangerous in some than others
Hands-on experience running LiteLLM
