Fullstack Developer for Rails and React Native Mobile App

We’re a small startup getting ready to launch our mobile app, and we need a solid Rails engineer to help us finish strong. Our app, Passive, helps busy professionals discover better career opportunities — without endless job board scrolling. We’re looking for someone who can jump in and own a few key pieces before launch: What you’ll do * Improve and troubleshoot third-party OAuth flows (Apple, LinkedIn, Google) * Debug Sidekiq background jobs and distributed workflows (e.g. scheduled scrapers) * Polish the app with **bug fixes, UI tweaks, and performance improvements** What we’re looking for * Strong Ruby on Rails experience (4+ years ideally) * Hands-on with OAuth 2.0 and major identity providers * Comfortable debugging Sidekiq, Redis, and Postgres workflows * Attention to detail — you care about both code quality and user experience * Bonus if you’ve worked with React Native, API integrations, or mobile launches
