Job Description: Full Stack Lead Developer
Summary of This Role
Serves as a technical leader and hands-on authority throughout the software development life cycle. This role acts in a strategic and engineering capacity to architect, design, code, review, and implement highly scalable full-stack applications. The Lead Developer bridges the gap between complex business logic, modern front-end user experiences built in React.js, and high-performance data warehousing layers. You will establish coding standards, drive architectural decisions, optimize system performance, and guide a team of engineers in a flexible, fast-paced Agile environment.

What Part Will You Play?
Technical Leadership & Mentorship: Acts as the primary Full Stack Subject Matter Expert (SME); establishes engineering best practices, conducts rigorous code reviews, and provides technical mentorship and on-the-job training to junior and mid-level software engineers.

Full-Stack Engineering: Architects and develops complex, secure, and performant end-to-end code using Java/Spring Boot for back-end services and React.js for modern, responsive user interfaces.

Data Layer Architecture: Designs, optimizes, and advises on complex program specifications to ensure seamless, high-speed interaction between UI components, backend APIs, and the Snowflake data layer.

Agile Governance: Actively drives and participates in all Agile ceremonies (Daily Stand-ups, Sprint Planning, Backlog Grooming, Retrospectives). Partners with Product Owners to break down complex Jira User Stories into technical tasks, manage velocity, and remove team blockers.

Security & Compliance: Leads architectural discussions regarding secure credential management and API security. Applies in-depth knowledge of Payment Card Industry (PCI) security compliance to all development and infrastructure activities.

Testing & Validation: Oversees the design and execution of comprehensive multi-level unit and integration testing to validate data accuracy across intricate partner hierarchies.
