Senior Full-stack / Rails Engineer, AI & Product Focused

Yuma AI, an innovative company building Autonomous AI Agents for customer support and e-commerce, is seeking a Senior Full-stack / Rails Engineer. The company, founded by Guillaume Luccisano (a 3rd time YC founder), has successfully developed a platform that helps merchants automate up to 60% of their support tickets.

The role sits within a small but dynamic engineering team of 6, where iteration speed and product focus are paramount. The tech stack centers around a Ruby on Rails API, supported by PostgreSQL, Redis, and Sidekiq jobs, handling millions of support tickets monthly. The position offers a unique opportunity to work with cutting-edge LLM technology while maintaining a strong focus on practical business applications.

The ideal candidate should be an experienced Rails developer who has led multiple large applications, with a pragmatic approach to balancing speed and quality. While the role leans towards backend work, frontend capabilities are essential. Recent experience with LLMs is increasingly important as the company continues to innovate in the AI space.

This is an excellent opportunity for a driven engineer looking to join an early-stage team with significant traction. The position offers the flexibility of remote work while being based in France, and the company culture emphasizes hard work, commitment, and delivering real value to users. Educational background is less important than demonstrated skills and capabilities.

Working at Yuma means being at the forefront of AI integration in customer support, with the chance to significantly impact how businesses handle customer interactions at scale.
