Senior Software Engineer

About this role

Berry Street is building on the convergence of AI, GLP-1s, and the consumerization of healthcare — while leveraging insurance to make life-changing metabolic care as accessible as possible for all. Our platform connects patients with 2,000+ clinicians and AI tools to treat obesity, diabetes/prediabetes, cardiovascular disease, kidney disease, maternal health, and dozens of other chronic and acute conditions, working with major health plans, health systems, and care management companies across all 50 states. We launched in 2023, have served hundreds of thousands of patients, and are Series B — backed by investors like Khosla, Northzone, FJ Labs, and the founders of Revolut, Grow Therapy, and Spring Health.

• Build the infrastructure that makes AI reliable in a clinical setting: evaluation pipelines, guardrails, feedback loops, the unglamorous stuff that makes the difference between a demo and a product
• Set technical direction on our platform, making architectural calls that shape how Berry Street scales from tens of thousands of patients to millions
• Own features end-to-end across provider- and patient-facing surfaces, from scoping and architecture th...
