Backend Engineer

About Marble Marble is fixing the youth mental health crisis by redefining what mental healthcare looks like in the AI era. Last year, 1 in 10 teens attempted suicide. At the heart of this crisis is a severe lack of access to effective care - when kids & families can't get the help they need, problems compound and preventable tragedies follow. We're fixing that by building the AI-native platform that provides affordable & timely access to truly effective care. Our platform: Brings together guardians, schools, therapists & insurers to collaborate togetherHas AI powered products for each of these stakeholders to surface the right info & give them the tools to be effectiveExtends the reach of care to support kids 24/7 through our patient companion, "Marty" We're an early-stage, fast-moving team. The people who join now will shape who we are & who we become, not just what we build but how we build. About The Role This is an early backend-leaning generalist role where you'll own truly life-changing products end-to-end. You'll work across an AI-first platform, whether that's building the school-facing product that connects students to care, the therapist product that makes clinicians more effective, Marty (our AI-powered patient companion), the revenue cycle management systems, or the internal platform & tooling that all of this is built on. You'll get to know and deeply understand our end users, and you'll partner directly with product, operations, growth, and clinical teams to ship experiences that expand access to care and elevate its quality. You'll bring strong opinions on what to build, raise the engineering bar, and help define what a thoughtful, AI-native engineering culture looks like at an early-stage company.
