Hippocratic AI is the leading generative AI company in healthcare. We have the only system that can have safe, autonomous, clinical conversations with patients. We have trained our own LLMs as part of our Polaris constellation, resulting in a system with over 99.9% accuracy.
Reinvent healthcare with AI that puts safety first. We’re building the world’s first healthcare‑only, safety‑focused LLM — a breakthrough platform designed to transform patient outcomes at a global scale. This is category creation.
Work with the people shaping the future. Hippocratic AI was co‑founded by CEO Munjal Shah and a team of physicians, hospital leaders, AI pioneers, and researchers from institutions like El Camino Health, Johns Hopkins, Washington University in St. Louis, Stanford, Google, Meta, Microsoft, and NVIDIA.
Backed by the world’s leading healthcare and AI investors. We recently raised a $126M Series C at a $3.5B valuation, led by Avenir Growth, bringing total funding to $404M with participation from CapitalG, General Catalyst, a16z, Kleiner Perkins, Premji Invest, UHS, Cincinnati Children’s, WellSpan Health, John Doerr, Rick Klausner, and others.
Build alongside the best in healthcare and AI. Join experts who’ve spent their careers improving care, advancing science, and building world‑changing technologies — ensuring our platform is powerful, trusted, and truly transformative.
We're hiring a Performance Engineer to own performance across our entire stack. You'll build the automated harnesses that keep us honest, continuously measuring every model, microservice, and infrastructure component, and be our expert voice on VoIP quality characterization. This is a high-impact, highly technical role that cuts across ML infrastructure, backend services, and real-time communications.
Build Automated Performance Harnesses
Design and maintain automated performance testing frameworks covering the full system: LLM inference, REST/gRPC microservices, and infrastructure components including PostgreSQL, Redis, message queues, and object storage
Integrate performance suites into CI/CD so every deploy is gated against latency and throughput regressions
Define SLIs/SLOs and build dashboards (e.g., Grafana) that give engineering teams real-time visibility into system health
Characterize VoIP Performance
Measure and track VoIP quality metrics: MOS scores, jitter, packet loss, latency, echo, and codec fidelity
Build synthetic call load testing infrastructure to stress telephony paths at scale
Correlate audio degradation signals with underlying infrastructure metrics to root-cause issues
Drive a Performance Culture
Partner with ML, Speech, Backend, and Infra teams to turn performance findings into prioritized engineering work
Contribute to incident reviews where latency or audio quality was a factor
Write runbooks, share learnings, and help other engineers instrument their own services
Must-Have:
10+ years in performance engineering with a solid software development and SRE background
Proven track record building automated performance test harnesses (Locust, k6, Gatling, JMeter, or custom tooling)
Deep hands-on experience with PostgreSQL performance tuning (execution plans, indexing strategies, connection pooling, autovacuum) and Redis (eviction policies, clustering, pipelining)
Solid grasp of distributed systems fundamentals: queueing theory, tail latency, backpressure, cascading failures
Fluency with observability tools: Prometheus, Grafana, Cloudwatch, etc.
VoIP / Telephony
Working knowledge of SIP, RTP/RTCP, and RTCP-XR
Hands-on experience with VoIP testing tools (SIPp or equivalent) and interpreting call quality reports
Ability to diagnose audio degradation across network, codec, and application layers
Familiarity with MOS scoring methodologies (PESQ, POLQA, or E-model)
Nice-to-Have:
Experience benchmarking ML inference servers: vLLM, TensorRT-LLM, Triton, or similar
Kubernetes workload profiling and resource right-sizing
Chaos engineering experience: Toxiproxy, Gremlin, or Chaos Monkey
Background in healthcare tech, real-time communications, or other high-reliability, latency-sensitive systems
Join us and help build the future of safe, life-changing AI in healthcare. There’s never been a more exciting moment to make an impact.
