Principal Engineer, AI Labs

About OpenLoop

OpenLoop was co-founded by CEO, Dr. Jon Lensing, and COO, Christian Williams, with the vision to bring care anywhere. Our telehealth support solutions are thoughtfully designed to streamline and simplify go-to-market care delivery for companies offering meaningful virtual support to patients across an expansive array of specialties, in all 50 states.

About the Role

OpenLoop is looking for an Principal Engineer, AI Labs who is both a technical authority and a hands-on builder. This is not a DevOps or SRE role. You’ll be writing production code, owning system architecture, and setting technical direction for how our infrastructure scales—while still jumping into the trenches when needed.

You’ll operate as a player-coach: leading through design, code, and execution.

What You'll Do

• Own system design on GCP (Cloud Run, Pub/Sub, BigQuery), including service boundaries, schemas, and reliability trade-offs.

• Lead development of event-driven data pipelines using Airflow, Spark, ETL, and Big Data tooling.

• Drive AI platform integration using open-source LLMs, embeddings, and speech models; define prompt optimization and evaluation strategies (e.g., LangFuse).

• Champion observability and operational excellence across ingestion, QA, and distributed workflows—especially for call transcripts and EHR data (FHIR/Medplum).

• Act as a player-coach: contribute code to critical paths while leading technical projects and mentoring engineers.

• Partner closely with Product, Design, and Clinical Ops to translate complex technical constraints into clear execution paths.

Who You Are

Required Qualifications

• 12+ years of software engineering experience; 5+ years as a Tech Lead or project lead.

• Principal-level scope or equivalent impact.

• Expert-level proficiency in Go, Python, or TypeScript/Node, with strong code review skills.

• Deep experience with distributed systems, containerized deployments (Docker, Kubernetes, Cloud Run), and event-driven architectures.

Strong working knowledge of GCP networking and data services.

Preferred

• Hands-on experience with open-source LLM hosting (vLLM, Ollama) and modern RAG architectures.

• Background in regulated environments (HIPAA, SOC 2) or healthcare data standards (FHIR, HL7).

• Strong written and verbal communication; comfortable authoring RFCs and technical strategy docs.
  

Our Benefits

In addition, for salaried positions you would also be eligible for:

• Medical, Dental, and Vision plans

• Flexible Spending/Health Savings Accounts

• Flexible PTO

• 401(k) + Company Match

• Life Insurance, Pet insurance, and more

Our Company

We have a relatively flat organizational structure here at OpenLoop. Everyone is encouraged to bring ideas to the table and make things happen. This fits in well with our core values of Autonomy, Competence and Belonging, as we want everyone to feel empowered and supported to do their best work.

Sound like a good fit? We’d love to meet you.
