Job Title
Sr. Full Stack Developer
What does a successful Fullstack Engineer do at Clover?
In this role, you will be a lead UI/UX-minded engineer responsible for driving the client-side evolution and expansion of our platform. While you have the full-stack capability to navigate backend APIs, your primary strength and passion lie in building exceptional web experiences, modern user interfaces, and modular frontend architectures. As part of the Loyalty Program team, you will own the user experience on the Clover Dashboard, translating complex data into sleek, responsive web applications used by over 700k merchants worldwide. Working alongside a strong team of dedicated backend engineers, you will bridge the gap between design, product, and services—owning web client features end-to-end, evaluating modern frontend technologies, and ensuring sub-second UI responsiveness at scale.
What you will do
- Architect, design, and develop high-performance, modular web-based frontend applications using React, TypeScript, and modern JavaScript, backed by supporting Java/Spring Boot microservices.
- Own the client-side architecture of the Clover Dashboard, establishing frontend best practices, state management standards, and component libraries.
- Partner with Product, UX, and core Backend Engineers to translate product requirements into intuitive, reliable web workflows and clean, extensible software.
- Design, consume, and optimize RESTful APIs and GraphQL/event-driven endpoints built for web clients, mobile dashboards, and 3rd-party app integrations.
- Promote effective use of AI‑powered engineering tools (e.g., AI coding assistants, automated test generation, code review, and UI performance profiling) to accelerate delivery and quality.
- Own client services and features from design through deployment, automated UI testing, and production monitoring.
- Participate in design and code reviews, advocating for modular code, responsive design, accessibility, and clean frontend architecture.
- Coach and mentor team members to improve their technical frontend capabilities, web performance optimization, and UI testing strategies.
- Participate in regular release management and cross-functional agile rituals across distributed teams.
