Staff Software Engineer, Machine Learning (LLM Backend) Location: Burlingame, CA (On-site, 4 days/week)

Employment Type: Full-time

Salary Range: $145K - $250K

We are a rapidly growing AI technology company transforming mission-critical processes in the healthcare industry . We are seeking a Staff Software Engineer to architect and scale the secure, reliable backend systems that power our advanced Large Language Model (LLM) applications. This role requires expertise at the intersection of applied AI, distributed systems, and security/compliance in a regulated domain.

You will be responsible for pushing LLMs beyond demos into mission-critical, cost-efficient, and secure production healthcare workflows. This is a technical leadership role driving the end-to-end delivery of core ML/LLM systems.

Key Responsibilities:

Backend for LLMs: Architect and implement scalable, low-latency APIs and services that wrap, orchestrate, and optimize LLMs for high-volume healthcare use cases (e.g., automated voice AI agents)
Data & Retrieval Pipelines: Build robust ingestion, preprocessing, and Retrieval-Augmented Generation (RAG) pipelines to ground LLMs in proprietary clinical and revenue-cycle data
LLMOps & Observability: Design and implement systems for model monitoring, evaluation harnesses, cost tracking, and guardrails, ensuring reliability and responsible use in production
Performance & Optimization: Engineer solutions for caching, batching, load balancing, and scaling LLM workloads across cloud and containerized environments
Security & Compliance: Implement HIPAA-ready infrastructure, robust data governance, and auditability for all LLM-powered applications in a regulated setting
Technical Leadership: Drive end-to-end delivery of LLM backend projects, establish engineering best practices, and mentor peers in complex LLM system design

Requirements

Experience: 5+ years of backend or full-stack software engineering experience, with 3+ years working specifically on ML/LLM-enabled applications
Coding Proficiency: Strong coding skills in Python and ideally experience with one statically typed language (e.g., Go, Java, or TypeScript)
LLM Integration: Experience with LLM integration frameworks (e.g., Hugging Face, LangChain, LlamaIndex, or direct APIs from OpenAI/Anthropic)
Cloud-Native Expertise: Deep knowledge of distributed systems, service-oriented architecture, and building APIs at scale. Hands-on experience with cloud platforms (AWS/GCP/Azure), Kubernetes, Docker, and Terraform
System Design & LLMOps: Excellent system design skills and familiarity with MLOps/LLMOps practices (CI/CD for models, evaluation, monitoring)
Location: Must be available to work 4 days a week on-site in the Burlingame office

Preferred Qualifications:

Experience applying LLMs in healthcare or other regulated industries (e.g., familiarity with FHIR, HL7, HIPAA)
Hands-on experience with RAG pipelines, vector databases, and structured-output orchestration
Background in enterprise SaaS or mission-critical platforms where uptime and strict compliance are paramount

Benefits

Highly competitive base salary ($145K - $250K) based on experience and qualifications
Equity Options as part of the total compensation package
Comprehensive Benefits: Health, dental, and vision coverage, and 401(k) plan
Unlimited PTO policy
Visa Sponsorship is available
A leadership role with ownership over core AI systems in a domain that drives significant, real-world impact
