Successful candidates often come from senior engineering roles and are experienced in leading complex projects, mentoring peers, and making architectural contributions across teams. ABOUT THE ROLE Fullstack engineering at Envoy sits at the intersection of product, systems, and real-world experience. The features you build touch everything — from the interfaces millions of people use to interact with their workplace, to the backend services and APIs that power those experiences at scale across tens of thousands of locations worldwide. As a Fullstack Engineer, you'll own meaningful product areas end-to-end, partnering closely with Product, Design, and Engineering to translate complex problems into simple, high-quality solutions. Your work spans the full stack — from scalable backend systems and APIs to performant, accessible frontend experiences. We value engineers who move fluidly across the stack and take pride in the quality of everything they ship. We hire for strong full stack fundamentals and a product mindset first. The balance between frontend and backend depth is flexible - some engineers skew heavier toward the frontend, others toward the backend. What matters most is end-to-end ownership and high-quality execution across the stack. Role Lean: Fullstack (50/50) This role requires equal depth across frontend and backend. UI craftsmanship and backend systems carry the same weight — you'll move fluidly across the stack, and neither side is secondary. Full end-to-end ownership is the expectation. This is an on-site position that requires 4 days a week (Monday through Thursday) in our San Francisco HQ office. YOU WILL - Build and ship high-quality, scalable features across the full stack — frontend UI, backend services, and APIs - Partner closely with Product, Design, and Engineering to deliver thoughtful, user-centered solutions - Design and evolve backend systems: APIs, data models, and services consumed by web and mobile clients - Build performant, accessible, and maintainable frontend experiences using React and modern web technologies - Contribute to architecture decisions, shared components, and engineering standards across the stack - Design and optimize relational data models (Postgres) and improve system performance and observability - Participate in code reviews, technical discussions, and continuous improvement of engineering quality - Own features end-to-end, from discovery and design through launch and iteration YOU HAVE - A BS or MS in Computer Science or a related technical field - 7+ years of experience building production software, with meaningful fullstack or cross-stack contributions - Strong frontend fundamentals, including React and JavaScript/TypeScript, with a solid foundation in HTML and CSS - Backend experience building and consuming APIs (RESTful and/or GraphQL), with production exposure to TypeScript, Java/Kotlin, and/or Ruby on Rails - Experience designing relational schemas and working with
