## Description

FBS is looking for a full stack engineer to build and improve customer-facing software across frontend, backend, and data integration layers. This role is best suited for someone who is comfortable moving between Ruby on Rails services, modern web UI development, system integrations, and the practical realities of shipping reliable product features. Experience working on customer-facing AI products is strongly preferred because this role will help shape user experiences where product quality, trust, and operational safety matter.

What you'll do:

 * Build and maintain backend services and web applications using Ruby on Rails.
 * Develop customer-facing frontend experiences using modern JavaScript frameworks, ideally React.
 * Design, implement, and support integrations with internal platforms, external APIs, and data services.
 * Translate product and technical requirements into well-scoped, testable changes.
 * Own features across the stack, from data modeling and service logic through UI behavior and production support.
 * Write clear, maintainable code with appropriate automated test coverage.
 * Troubleshoot bugs, production issues, integration failures, and data inconsistencies.
 * Participate in technical planning, estimation, code review, and iterative delivery practices.
 * Work closely with QA, product, and design to improve usability, reliability, and release readiness.
 * Help document systems, implementation decisions, edge cases, and operational considerations.
