About The Position

We're looking for a Senior Full-Stack Engineer with 3+ years of experience to join our client's Care Journey team — the team that owns the core experience members have when they first engage with care on the platform. This is a product-minded IC role for someone who leans backend-heavy but can work confidently across the stack. You'll own features end-to-end in a startup environment, partnering closely with product and design to ship meaningful user outcomes.

Requirements

• 3+ years of full-stack engineering experience shipping production web applications
• Experience building and shipping user-facing products end-to-end
• Strong backend/API experience, including REST and GraphQL
• Strong proficiency in Python, React, and PostgreSQL
• Strong product mindset and ability to collaborate closely with product and design
• Strong communication with both technical and non-technical stakeholders

Nice To Haves

• Experience in a VC-backed startup or growth-stage environment
• Healthcare, mental health, or benefits platform experience

Responsibilities

• Design, build, and iterate on end-to-end product features powering the Care Journey experience, connecting backend systems with frontend interfaces
• Own features from technical design through implementation, rollout, and continuous iteration
• Develop and maintain backend services and APIs (REST and GraphQL) for user-facing applications and service-to-service interactions
• Build and refine frontend components in React with a focus on usability, performance, and user experience
• Model and manage application data in PostgreSQL — clean, well-structured data design
• Work closely with PMs and designers to translate business needs into high-quality, user-centric solutions
• Contribute to technical design discussions; shape pragmatic solutions aligned with product goals
• Mentor engineers and help foster a strong product mindset across the team
