About the role

  • Design, deploy, and maintain end-to-end AI/ML systems (data → model → inference → service).
  • Build robust evaluation, monitoring, and feedback pipelines for production ML.
  • Integrate LLMs, retrieval systems, and semantic/voice pipelines into customer-facing products.
  • Collaborate cross-functionally with Product and Infra to translate ML trade-offs into product outcomes.
  • Drive experimentation speed and model reliability through CI/CD, metrics, and instrumentation.
  • Deploy and optimize a low-latency inference pipeline (<0.5 s target).
  • Audit and improve evaluation metrics, drift detection, and guardrail coverage.
  • Partner with Product to define success metrics for reliability and responsiveness in voice workflows.
  • Deliver production-ready LLM or voice AI systems integrated with Sully’s core stack.
  • Establish automated evaluation and monitoring tied to user feedback loops.

Requirements

  • Demonstrable track record deploying AI/ML models in production.
  • Strong software foundation (TypeScript, APIs, distributed systems).
  • Familiarity with ML frameworks (PyTorch, TensorFlow, Hugging Face or similar).
  • Experience building inference, evaluation, and monitoring pipelines.
  • Excellent communication and collaboration skills across technical and non-technical teams.
  • Experience with LLMs, embeddings, or RAG pipelines in SaaS or startup environments.
  • Familiarity with telephony APIs (Twilio/SIP/VoIP) and real-time ASR/NLU pipelines.
  • Experience in healthcare, call center, or real-time conversational AI systems.
Benefits
