AI Engineer – Voice AI / Autonomous Agents

Spyne is redefining how cars are marketed and sold with cutting-edge Generative AI. We are looking for a Senior AI Engineer – Voice AI / Autonomous Agents to own and build Spyne's in-house voice bot stack. This is a high-impact individual contributor role at the intersection of LLMs, ASR/TTS, and voice UX, focused on creating deeply human, latency-optimized conversations between auto dealerships and their customers. The role involves building and owning the end-to-end voice bot pipeline — ASR, NLU, dialog state management, tool calling, and TTS — to create a natural, human-like conversation experience. Architect systems using MCP (Model Context Protocol) to mediate structured context between real-time ASR, memory, APIs, and the LLM. Implement retrieval-augmented generation to ground responses using dealership knowledge bases, inventory data, recall lookups, and FAQs. Design scalable vector-based search for dynamic FAQ handling, call recall, and user-specific memory embedding. Engineer low-latency, streaming ASR + TTS pipelines and fine-tune turn-taking models for natural conversation. Use fine-tuning, LoRA, or instruction tuning to customize tone, reduce hallucinations, and align responses to business goals. Build robust observability, run real-time call QA pipelines, and analyze interruptions, hallucinations, and fallbacks. Work closely with product, infra, and leadership to scale this bot to thousands of US dealerships.

You understand how ASR, LLMs, memory, and tools fit together — and can design modular, observable, and resilient systems. You've implemented tool calling, retrieval pipelines, function calls, or prompt chaining across multiple workflows. You know how to chunk, embed, index, and retrieve — and how to avoid prompt bloat and token overflow. You debug token delays, know the cost of each API hop, and can optimize round-trip time to keep calls human-like. You know how to trace hallucinations back to weak prompts, missing guardrails, or lack of tool access — and fix them.
