As a Senior Fullstack Engineer on the Loyalty Program team, you will help improve and expand our platform by building applications, creating new features, and re-architecting systems for better scalability and availability across the Clover Dashboard.

- Own services and features end-to-end from initial development through deployment, production monitoring, and on-call release management rotations.
- Promote the effective use of AI-powered software engineering and productivity tools (AI coding assistants, test generation, code reviews, documentation, and incident analysis) to improve developer efficiency and code quality.
- Translate product requirements into functional, extensible software while partnering with cross-functional, distributed Agile teams to assist with project planning and feature development.
- Partner with the Infrastructure and QA teams to design data models supporting large-scale, highly available services and develop comprehensive test plans.
- Coach and mentor junior engineers, advocate engineering best practices with a CI/CD DevOps mindset, and help define the technical software roadmap.
- Triage bugs, resolve operational issues, participate in design/code reviews, and evaluate modern frameworks to improve product performance.
