About the role

Key responsibilities & impact

Drive collaboration on technical direction for complex, cross-cutting systems — data modeling, API design, clinical workflow architecture, and integration patterns
Scope and shape work end-to-end: from identifying the right problem to solving it, collaborating closely with product and design to define what “done” looks like
Write code across the entire stack (currently Ruby + Rails on the backend and Turbo/Tailwind on the frontend) with a focus on the systems and abstractions that other engineers build on
Evaluate technical risk and tradeoffs clearly — know when to invest in architecture and when to ship the simplest thing that works
Mentor and elevate the team through architecture discussions, pairing, code review, and setting high standards without gatekeeping
Build deep domain expertise in our problem space and use it to challenge product assumptions, surface risks early, and advocate for provider and member experience
Collaborate across engineering, product, design, and clinical/operations teams to ensure technical decisions serve business and clinical goals

Requirements

What you’ll need

You're excited about improving behavioral health for children, teens, and their families
You have significant experience developing software professionally, primarily Ruby + Rails, with a track record of influencing technical direction beyond your own code
You shape how the team thinks about systems — you see how individual features connect to the broader architecture and can articulate tradeoffs to technical and non-technical stakeholders
You own problems, not just tickets — you dig into the domain, question assumptions, and find the right solution even when it's not the obvious one
You are thoughtful and empathetic in how you carry yourself, from decision making and execution, to communication and collaboration
You raise the bar for the team through your work, your feedback, and your willingness to make things better without being asked
You thrive in a flat, self-managing team where influence comes from clarity and trust, not authority
You have developed your own workflow for building software with AI coding tools — you have opinions about when agents help, when they hurt, and how to get the best out of them
You care about solving problems and aren't tied to particular solutions or technologies
Bonus Points:
- Healthcare — especially clinical workflows, scheduling systems, EHR integrations, insurance billing, or multi-clinic operations
- Complex data modeling and migration challenges (unifying systems, managing domain complexity)
- API development and integrating with third-party systems
- Working in Shape Up or similar appetite-based development methodologies
