Who We're Looking For

We are looking to hire a Senior Software Engineer I, (L3) for the Applications Team who will own and drive the technical direction of CareMessage's core SaaS application, the full-stack product that clinic staff at over 400 safety-net healthcare organizations in the United States rely on every day to manage their patients, build and run communication programs, and measure patient engagement outcomes. You will independently own complex features end-to-end across our Rails backend and React frontend, mentor L2 engineers on the team, and contribute to architectural decisions that shape how we evolve the core product. This is a highly cross-functional role with shared team lead responsibilities. You'll work closely with Product, Customer Success, Data, and Engineering to design and deliver features that meaningfully reduce the administrative burden on safety-net clinics and deepen patient engagement. You will report to the Director of Engineering and play a key role in advancing our core product capabilities as we scale. Who You Are You are a seasoned full-stack engineer who thrives in dynamic, fully distributed environments. You bring deep experience building and scaling production web applications end-to-end and are fluent on both sides of the stack: Ruby on Rails on the backend and modern React on the frontend. You are energized by the challenge of delivering intuitive UX on top of a mature domain model, tackling problems like complex form workflows, data-heavy dashboards, role-based access, and clinic-specific configuration, and you have the technical leadership to guide and mentor your teammates across both frontend and backend work. You take a scientific approach to everything you do. You rely on evidence, not intuition, and you look for data that challenges your assumptions before drawing conclusions. You contribute to PRDs, documentation, and wikis with this same mindset, using data to guide decisions and validate your work. You're excited about operating in a mission-driven, fast-moving environment and bring the experience and ownership mentality to lead from the front. Most importantly, you share our commitment to advancing health equity for low-income populations and take pride in contributing to that mission through the systems you build.
