Sr. Software Engineer, Ruby on Rails
Key Accountabilities:
Help shape technical direction on the Essentials squad — contributing to architecture decisions and unblocking teammates — while staying hands-on in Ruby on Rails, TypeScript, and React
Lead by example in the codebase: write clean, maintainable, refactor-friendly code and elevate quality through thoughtful code review and pairing
Design and optimize back-end systems, APIs, and data flows with a strong focus on performance and reliability, sharing what you learn along the way
Build modern, responsive front-end experiences using React, TypeScript, and CSS, with an eye toward maintainable architecture
Work across relational databases (Postgres, MySQL, etc.), writing efficient SQL and shaping data models that support business growth
Lead projects end-to-end, balancing hands-on development with guiding others to successful delivery, surfacing risks early and communicating trade-offs clearly
Collaborate cross-functionally with product, design, and QA to translate business needs into sound technical solutions
Embrace AI-assisted engineering: use tools like Claude Code and GitHub Copilot effectively, contribute to shared prompts and agentic workflows, and help the team learn what works
Identify and prototype opportunities to apply LLMs and automation to engineering and internal workflows, with the guardrails appropriate to healthcare data and regulated billing

Passionate about mentoring, from pair programming to guiding architectural decisions, and helping others grow as engineers
Daily, hands-on fluency with AI development tools (e.g., Claude Code, Cursor, Copilot), with sharp judgment about where AI accelerates work and where human review is non-negotiable
Experience, or strong demonstrated interest, in building with LLM APIs: prompt design, evaluation, and safety considerations for sensitive data
Highly organized with superb attention to detail
Strong project management skills: comfortable with planning, estimation, and scoping
Proven ability to work in an ever-changing environment, ability to connect the dots and make decisions on your own feet
Ability to produce quality materials within tight timeframes and simultaneously manage several projects
