Company mission
To provide patients unlimited access to personalized, high-quality medical advice from real clinicians.
Role
Who you are
- 5+ years building production backend systems, ideally in high-growth environments
- Experience designing and maintaining external-facing APIs used by customers or partners
- Strong data modeling instincts, particularly around time-series or high-frequency data
- Experience working with distributed systems and multi-tenant architectures
- Comfort contributing to greenfield architectural design while shipping pragmatically
- You care deeply about API craftsmanship and long-term system design
- You’ve built complex systems that external customers rely on
- You enjoy modeling messy real-world data — especially high-frequency signals — into clean, durable abstractions
- You’ve built comprehensive search or RAG production systems at scale
- You’ve helped scale early systems from 1 → 10 in a fast-paced environment
- You thrive in small, high-leverage teams where ownership is real
- You have a track record of maintaining and up-leveling operational excellence across software organizations
What the job involves
- We are seeking a talented, driven, and experienced Senior Backend Engineer to join us in defining the future of AI + human healthcare
- You will sit on our Platform & Integrations team and own the critical product primitives that the rest of the company builds on — including external APIs, health data models, retrieval infrastructure, and enterprise integrations
- This role is central to ensuring our platform scales seamlessly — supporting enterprise healthcare clients, powering AI-driven clinical workflows, and maintaining correctness and reliability across distributed systems
- Much of this surface area is greenfield, particularly in how we model and operationalize longitudinal health data from wearable devices and external systems
- Our culture is fast-paced and ambitious, and we aim for every team member to be exceptional
- Design and evolve our external API and embedded product layer, ensuring long-term stability, disciplined versioning, and enterprise-grade API craftsmanship
- Evolve our agentic retrieval harness to support both patient and clinical search workflows across structured and unstructured data, with strict permission and audit guarantees
- Build reusable platform primitives that allow external partners to embed and extend our AI capabilities — ensuring every integration produces lasting platform leverage
- Contribute to our core data models that unify structured health records, unstructured inputs, and high-frequency time-series signals
- Examples of projects you may work on
- Develop a pluggable ingestion framework that normalizes data from third-party sources into canonical internal models, with extensible adapters for new partner onboarding
- Build a stateful, multi-turn, agentic API that allows external clients to customize AI agent behavior and capabilities within their own cloud, deployment environments
Our take
Counsel Health is a virtual healthcare platform offering an AI-enabled, asynchronous care platform connecting patients with real clinicians via 24/7 messaging.
While the digital health space is competitive, with companies offering similar text-based services, Counsel stands out by providing personalized care from real physicians. The platform combines the efficiency of AI technology with high-quality care from senior medical professionals.
With plans to expand its coverage to additional states, Counsel is ready for rapid scaling. It has raised considerable funding to support the growth of its physician network, continued investment in AI, and the forging of new partnerships. It already serves more than 100,000 members nationwide.
