Experience the thrill of shaping a world-class matchmaking platform as a Senior Backend Developer
About the Opportunity
NousLib is not just another dating app. With over 2.5 million users, triple-digit growth, and a place in the Top 10 Lifestyle Apps in France, they're revolutionizing how open-minded people connect.
You'll join their remote-first tech team via Workana Premium and lead feature work that touches both product and platform. The app is built on Rails with a sleek mobile webview, scaling fast across Europe, Japan, and the UK.
Your first months will focus on two high-impact projects:
* A custom in-house customer service platform (think Zendesk, rebuilt for the privacy-sensitive needs of a dating app)
* A story-based matching feature where users connect through shared fantasies – match on desire, not looks.
Both projects will challenge your backend expertise and offer plenty of room to improve architecture, performance, and team processes.
Key Responsibilities
* Implement backend features in Ruby on Rails for both web and mobile
* Design performant APIs and services that scale
* Collaborate with frontend (Vue/React) and mobile freelancers
* Refactor legacy logic and improve performance on high-traffic code
* Drive technical decisions as you grow into deeper ownership
Requirements
* 5+ years of professional experience with Ruby on Rails
* Strong database skills (MySQL, Redis, MongoDB)
* Solid frontend awareness (React/Vue, HTML/CSS) – you'll interface with it, not own it
* Collaborative mindset – you'll work with a distributed team across LATAM and Europe
* Familiarity with mobile (Swift/Kotlin) ecosystems is a plus
* Self-sufficient, communicative, and product-aware
Benefits
* Fully remote, async culture – work autonomously with no micromanagement
* Join a senior team with real product vision
* Trip to Paris after 8 months to meet the team
* Impact features seen by millions of users
