Senior Software Engineer (Backend Leaning)

🏥 About Marble Health

Marble is building the operating system for youth mental health, connecting schools, therapists, families, and payers to deliver effective care to kids who need it most. We’re growing 40% MoM, just raised our Series A ($15.5M led by Inspired Capital), and are expanding rapidly beyond New York.

Our platform integrates scheduling, communication, documentation, billing, and more – all to reduce friction for providers and improve care for kids. We're on a mission to empower a healthier, happier generation, and we're just getting started.

⭐ Role Overview

We’re looking for a senior backend leaning engineer to help scale Marble’s care delivery platform for youth mental health. This is a critical role for someone excited to build the infrastructure, systems, and processes that power everything from billing to therapist workflows — while helping us scale responsibly and sustainably.

You’ll be a technical leader focused on our revenue cycle management (RCM) systems, platform architecture, and backend engineering excellence. You’ll own a high-leverage surface area that directly impacts our ability to grow, and help build a world-class engineering culture from the ground up.

💻 What You’ll Do

Own and evolve Marble’s RCM / billing systems

• Build and maintain the systems that ensure Marble gets paid. This includes everything from payer integrations to claims submission, reimbursement flows, and reporting. RCM is a core pillar of our business, and you'll own it end-to-end.

Build core platform infrastructure

• As we move from a single monolith to a more scalable architecture, you’ll help lead the design and implementation of our platform foundation—including event-driven systems, internal tooling, data pipelines, and DevX / infra improvements.

Up-level engineering standards and provide mentorship

• Be a senior voice on the team. Mentor engineers, set the standard for clean, maintainable code and champion best practices. Mentor teammates and help grow a strong, thoughtful engineering culture.

Be a cross-functional partner

• Collaborate closely with product, operations, and clinical teams to ensure our systems support real-world needs—and that we build with empathy for the humans using our tools.
