Overview

Audio AI Recruitment Consultant @ Lumicity | Recruiting Researchers & Engineers with Foundational AI Experience

We're on a mission to take LLMs beyond demos and embed them into mission-critical healthcare workflows. We're looking for a Staff Software Engineer to own and scale the backend systems that power our AI-driven products. If you thrive at the intersection of backend architecture and applied AI—and want your code to directly improve healthcare—you'll feel right at home here.

What You'll Do
  • Build the Backend for LLMs – Architect scalable, low-latency APIs and services that wrap, orchestrate, and optimize models.
  • Engineer Data & RAG Pipelines – Ingest, preprocess, and ground LLMs in clinical and revenue-cycle data.
  • Lead LLMOps & Observability – Deliver monitoring, cost tracking, and guardrails to keep systems reliable and safe.
  • Optimize at Scale – Design caching, batching, and load-balancing strategies for cloud-native LLM workloads.
  • Ship Secure Systems – Build HIPAA-ready infrastructure with rigorous data governance.
  • Collaborate & Lead – Partner with ML engineers, product, and healthcare experts while mentoring peers and setting best practices.
What You Bring
  • 5+ years of backend/full-stack engineering (3+ with ML/LLM-enabled systems).
  • Fluency in Python + a statically typed language (Go, Java, TypeScript, etc.).
  • Experience with LLM frameworks (LangChain, LlamaIndex, Hugging Face, OpenAI/Anthropic APIs).
  • Familiarity with CI/CD for ML, monitoring, reproducibility, and LLMOps.

Bonus: Experience with healthcare data standards (FHIR, HL7, HIPAA), RAG pipelines, vector DBs, and safety/privacy techniques.

Why Join
  • Shape the future of how LLMs are used in healthcare.
  • High ownership in a leadership-level role with direct product impact.
  • Competitive salary, equity, and full health/dental/vision benefits.
