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.
Responsibilities
- You will contribute to the technical delivery of key messaging platform features, collaborating with Product, Customer Success, Data, and Engineering to build solutions that deepen patient engagement and health outcomes
- You will build and maintain backend messaging systems using Ruby on Rails, including SMS/voice delivery pipelines, consent management workflows, message scheduling and orchestration, and Twilio integration layers
- You will share team lead responsibilities with peers, including mentoring L2 engineers, leading technical design discussions, conducting code reviews across both repos, and helping set technical direction for the Applications team.
- You will contribute to architectural discussions and learn from the design decisions that shape how we build and scale our messaging infrastructure, including delivery optimization, AI-driven message categorization, and multimedia messaging (MMS/RCS)
- You will provide technical training and documentation for features you build and maintain, enabling support teams to monitor, troubleshoot, and measure the impact of product features in production.
- You will work closely with Product teams to understand requirements and lead technical input during solution definition, including ownership of technical scoping and active participation in Product Requirements Documents (PRDs).
- You will help improve the team over time through essential team rituals, such as Kickoffs, Retrospectives, and Technical Debt Reviews.
- You will contribute to the team by participating in On-Call (PagerDuty) activities.
Requirements
- Minimum 8 years of hands-on software engineering experience, with strong proficiency in Ruby on Rails and JavaScript.
- Minimum 8 years of full-stack experience building, maintaining, and scaling production backend systems, APIs, and services, with demonstrated experience owning complex features from API design through UI delivery.
- Solid fundamentals of computer programming, including a good understanding of software development lifecycle, coding best practices, design patterns, object-oriented architecture, and component-based frontend design.
- Advanced SQL proficiency with a strong analytical mindset, comfortable querying and working with large, complex datasets to uncover insights, troubleshoot issues, and inform technical decisions.
- A commitment to supporting and fostering diversity and inclusion (we have a global team and you will regularly collaborate with people from a variety of walks of life).
- Demonstrated ability to independently own and deliver complex projects end-to-end, break down large features into manageable tasks, mentor junior engineers, and influence technical direction within a team.
- Growth-oriented mindset.
- Outstanding written and verbal communication skills, especially in a fully remote environment.
- Excellent ability to collaborate with technical and non-technical partners to support discovery, development, and testing phases of application features.
- Experience working in teams where automated tests are an expected part of development, including writing and maintaining tests alongside production code on both backend and frontend.
- Proven ability to work autonomously, proactively identifying challenges before they escalate, driving solutions independently, and maintaining clear, consistent communication with stakeholders to keep projects moving forward.
Preferred Qualifications
- Experience with Twilio (SMS, Voice, or Messaging APIs) or similar messaging and communications platforms
- Experience with RCS (Rich Communication Services) or multimedia messaging (MMS)
- Experience with our tech stack: Ruby on Rails, JavaScript (React), PostgreSQL, Google Cloud Platform, background job processing (Sidekiq or similar)
- Experience with message queue systems, event-driven architecture, or high-throughput delivery pipelines
- Experience in healthcare technology or familiarity with messaging compliance requirements, including TCPA, opt-out management, consent workflows, A2P 10DLC, and The Campaign Registry (TCR)
