Note: The job is a remote job and is open to candidates in USA. Castlight Health is hiring a Staff Full Stack Engineer to drive end-to-end technical execution across its consumer health products. The role builds complete product experiences across backend services and frontend interfaces, partners with product managers on prototypes, and improves engineering standards and performance.

Responsibilities

• Build End-to-End Solutions: Architect, write, and deploy complete product slices—building scalable Java Spring / Python backend services on GCP and crafting white-labeled micro-frontends in Angular
• Drive Rapid POCs & Prototyping: Partner directly with Product Managers to take raw 0-to-1 ideas and rapidly transform them into polished, production-ready experiences
• Elevate Engineering Standards: Raise the bar for code quality, deployment speed, and system architecture across both frontend and backend domains
• Optimize Full-Stack Performance: Bridge the gap between server response times and client-side rendering to create ultra-fast, seamless consumer experiences for millions of users

Skills

• A True Full-Stack Engineer: Jack-of-all-trades and master of them too. You operate comfortably across the entire technology stack—from deep backend architecture in Java Spring and Python to fluid micro-frontends in Angular, seamlessly switching context where others see boundaries
• Unapologetically High-Agency: You don't wait for rigid handoffs or endless alignment meetings. If a feature needs a new API endpoint, a microservices update on GCP, and an intuitive UI component, you take full ownership and ship it end-to-end
• Obsessed with End-to-End Craft: You care just as much about the micro-interactions and responsiveness of a web application as you do about the throughput, resilience, and latency of the microservices powering it
• The Ultimate Escape Hatch: When time is critical and something needs to be built or shipped *right now*, you are the engineer we call. You cut through red tape, figure out a path forward, and deliver under pressure without missing a beat
• Mission-Driven & Relentless: You embrace nimble, fast-moving environments. You seek to eliminate unnecessary friction, navigate complex systems effortlessly, and take pride in building software that directly impacts millions of people
• 8+ years of software engineering experience spanning both frontend and backend software development at scale
• Strong expertise in Java (Spring / Spring Boot) and/or Python, with a track record of building resilient, high-throughput RESTful microservices on GCP
• Deep expertise in modern JavaScript/TypeScript and frameworks (Angular preferred, but React/Vue expertise welcomed)
• Experience building scalable micro-frontends or design systems
• Proven capability to take complete ownership of complex features, delivering both backend endpoints and UI components end-to-end
• Comfortable working with cloud infrastructure (GCP), CI/CD pipelines, containerized environments, and micro-frontend architectures
• Exceptional ability to articulate end-to-end architectural decisions, trade-offs, and product requirements across both technical and non-technical teams
• Angular preferred

Benefits

• Full freedom to operate across the entire stack with minimal bureaucracy and zero context-switching friction.
• Direct ownership over key consumer features that scale to millions of healthcare users.
• Build technology where seamless user experience and backend efficiency directly enable people to access the healthcare they need.
