Senior Full Stack Engineer (React + Java)
About the Position
We're hiring a Full Stack Engineer to work across both the Java/Spring Boot backend and the React/TypeScript frontend of the platform. This is a flexible full-stack role: we're open to candidates who are strong in one stack and still building depth in the other — a backend-strong engineer growing into React, or a frontend-strong engineer growing into Java — rather than requiring equal mastery of both from day one. What matters is the ability to reason across the full stack, collaborate on API contracts, and take ownership of features end-to-end. We are looking for an AI-first engineer — someone who actively incorporates AI-assisted tooling into their day-to-day development workflow to accelerate delivery, rather than treating it as an afterthought.
About the Project
This role supports a multi-tenant crisis intervention platform serving the 988 National Suicide & Crisis Lifeline across multiple state tenants and handling chat, SMS, and voice contacts. The active backlog includes referral routing logic, episode and admissions-tab workflows, region- and facility-based filtering, a configurable notification framework, and tiered admin permissions, spanning both backend services and frontend delivery, with several items requiring solution design before implementation.
Requirements
- Candidates should have strong, hands-on experience in at least one of the two stacks below, plus working proficiency in the other.
- Experience with Java and Spring Boot, including REST API design and service-layer architecture.
- Solid SQL experience and comfort working with data-driven applications.
- Understanding of authentication/authorization patterns and secure API design.
- Strong proficiency in JavaScript (ES6+) and React.js; experience with TypeScript.
- Experience with state management libraries (e.g., Redux, Zustand, Recoil).
- Understanding of RESTful APIs and asynchronous programming on the client side.
- Familiarity with version control (Git) and Agile delivery.
- Comfort working in multi-tenant, permission-tiered systems.
- Strong problem-solving skills and attention to detail; product-driven mindset.
- Upper-Intermediate English or higher.
Nice to Have
- Experience in healthcare or other regulated industries.
- Exposure to AWS-based service integrations.
- Testing framework experience (Jest/React Testing Library on the frontend; JUnit on the backend).
- Interest in growing full-stack ownership over time rather than staying single-stack long-term.
- Experience with WCAG and web accessibility.
