Job summary

Storm3 is seeking a Senior Full-Stack Engineer to own the core product end-to-end in a single TypeScript monorepo. Frontend uses Vue 3, backend runs on Express with MongoDB, and shared packages bridge the stack.

• Strong TypeScript across the stack, plus hands-on Vue 3.
• Node, Express, and MongoDB/Mongoose experience.
• Strong grasp of query performance, indexing, and schema design.
• A track record of improving large existing codebases instead of rewriting them.

Responsibilities

• Build Vue 3 (Composition API) screens on an internal component library.

• Model clinical and patient data in MongoDB so it stays fast as it scales.
• Contribute to shared TypeScript packages used across the codebase.

Job description

Senior Full-Stack Engineer | Series B Healthtech | NYC (Hybrid)

A recently funded Series B company is building the clinical operating system for MSK and specialty care clinics. The platform covers patient acquisition, clinical workflows, and ongoing patient engagement.

The Role

You’ll own the core product end to end in a single TypeScript monorepo: Vue 3 on the frontend, Express and MongoDB on the backend, and shared packages in between. The hardest problems come from messy clinical data and real patient behavior, not algorithms. The team works contract-first, so API schemas are shared and type-checked on both the frontend and backend.

What You'll Do

• Build Vue 3 (Composition API) screens on an internal component library
• Design contract-first API routes with shared schemas
• Model clinical and patient data in MongoDB so it stays fast as it scales
• Contribute to shared TypeScript packages used across the codebase
• Take features from spec to production and support them once they're live

Required

• 5+ years shipping production web apps
• Strong TypeScript across the stack, plus hands-on Vue 3
• Node, Express, and MongoDB/Mongoose experience
• Strong grasp of query performance, indexing, and schema design
• A track record of improving large existing codebases instead of rewriting them

Nice to Have

• Clinical workflow knowledge or HL7/FHIR/EHR integration experience
• Twilio, LiveKit, or OpenAI API experience
• Real-time or streaming apps
• Workflow orchestration (Temporal, Cadence, Step Functions)
