Join us to Improve Health Equity for 5 Million People!CareMessage is the technology non-profit building the largest patient engagement platform for low-income populations in the United States. Powered by the Health Equity Engine™, the platform enables organizations to combine messaging, data, and interoperability to increase access to care, improve clinical outcomes, and address social drivers of health.
With 20 million patients reached since 2013, CareMessage is the only patient engagement solution proven to improve health equity at scale. The team, many with lived experiences in these communities, leverages a nonprofit model to reinvest revenue into impact. CareMessage is the partner of choice for organizations committed to advancing health equity.
Who We're Looking For We are looking to hire a Senior Software Engineer I, (L3) for the Messaging Team who will own and drive the technical direction of CareMessage's messaging platform which is one of the core systems powering patient communication for over 400 safety-net healthcare organizations in the United States. You will independently own complex features end-to-end, mentor other engineers on the team, and contribute to architectural decisions that shape how we build and scale our messaging infrastructure.
This is a highly cross-functional role with shared team lead responsibilities. You'll work closely with Product, Customer Success, and Engineering to design and deliver messaging features that deepen patient engagement and health outcomes, with direct ownership of technical decisions and customer-facing system behavior. You will report to the Director of Engineering and play a key role in advancing our messaging capabilities as we scale.
Who You Are You are a seasoned backend engineer who thrives in dynamic, fully distributed environments. You bring deep experience with Ruby on Rails and messaging systems at scale, and take pride in building reliable, patient-centric communication infrastructure. You are energized by the challenge of delivery optimization, consent management, and AI-driven messaging and you have the technical leadership to guide and mentor your teammates.
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.
