Join Cartwheel to help tackle the student mental health crisis
Cartwheel is an early-stage company building a new kind of mental health program for kids that puts schools at the center. We see our role as supporting school staff who see kids every single day. Instead of going around them, we collaborate with them. This means:
- Earlier intervention
- Higher student and family engagement in care
- Better coordination among the trusted adults in a student's life
Kids shouldnt just aspire to get out of bed and drag themselves to class. They should be able to experience joy. They deserve to envision and build a life they're excited to live. If you join Cartwheel, you'll help make this vision a reality for millions of students across the country. We're backed by top investors including Menlo Ventures, Reach Capital, General Catalyst, BoxGroup, and Able Partners, and were looking for mission-driven teammates to join our team.
As a Senior Software Engineer at Cartwheel, youll build the product that connects students, families, therapists, and schools in real time. Youll work on a full-stack team of 5-6 engineers, owning features end to end - from the architecture decisions that shape how we scale, to the code that goes to production and touches real students and clinicians the next day. This is a company thats large enough to be real (Series B, operating in districts across the country) and small enough that your pull requests are not invisible.
Were looking for a product engineer, not a ticket-taker: someone who cares as much about whether a feature actually works for a school counselor at 8am on a Monday as they do about the code that powers it. You should also be comfortable working as a forward-deployed engineer, sitting with clinicians, school staff, and our care team, watching them use what we built, and turning what you see into shipped changes quickly. Sometimes that means writing the tool yourself instead of filing the ticket.
The industries we work in, healthcare and education, havent historically moved fast on technology. Thats the opportunity, not the constraint.
Role type: This is a W2, Full-Time, Salaried position
Location: Remote, based in the United States
Start date: September 2026
Salary: $170,000 - $200,000 + meaningful equity
HOW WE WORK: AI-FIRST
We are an AI-first engineering team, and we mean it as a practice rather than a slogan. Agents are part of our day-to-day toolchain, and the context that makes them effective, styleguides, agent skills, architecture docs, evals, lives in the repo and is maintained like any other code. We expect engineers to keep asking what should be automated, what should be deleted, and where AI can raise the quality or speed of our work, in our own workflows and in the product itself. If youre the kind of engineer who is constantly rethinking how the work gets done instead of just doing more of it, youll fit here.

- Support new hire onboarding, and contribute to a culture of learning through talks, content, or workshops Serve as engineering on-call, and help identify, triage, and resolve issues beyond your own teams surface area
Cross-Functional & Forward-Deployed Collaboration
- Partner closely with product managers, designers, and clinical stakeholders to translate user needs into technical solutions
- Work directly with the people using our product, clinicians, school staff, and our care and operations teams, to understand their workflows firsthand and close the loop quickly on what you learn
- Communicate technical concepts effectively to non-technical stakeholders, ensuring alignment between engineering capabilities and business objectives
