We are looking for a Ruby on Rails Developer to join the engineering team of one of our Health clients — one of the largest health benefits platforms in Brazil and Mexico, providing access to over 29,000 gyms across more than 2,500 cities.

You will operate with high autonomy, growing and developing in an environment where quality is the direct responsibility of the developer — without separate QA teams: whoever develops also tests, guarantees, and sustains the solution. **Responsibilities and assignments** **What you will do** * Develop and maintain scalable, resilient RESTful APIs using Ruby on Rails * Participate in the full development lifecycle: architecture, implementation, automated testing, deployment, and production monitoring * Contribute to evolution of the core (monolith) as well as microservices initiatives and integrations with partners (e.g., ERPs, payment gateways, external platforms) * Ensure technical quality via Code Review, engineering best practices (Clean Code, SOLID), and team standards * Monitor and optimize performance: APM, resource tuning, query analysis and optimization * Work in multidisciplinary agile squads (Scrum/Kanban), with close collaboration between engineering and product * Navigate across contexts (as needed) with TypeScript and mobile teams, maintaining a systemic perspective **Requirements and qualifications** **What we seek** * Proven senior-level experience with Ruby on Rails * Proficiency in REST APIs (design, documentation, and consumption) * Solid experience with PostgreSQL and data modeling * Experience with Git/GitHub * Strong familiarity with automated testing (e.g., RSpec — and understanding of unit, integration, and black-box testing approaches) * Hands-on experience with Cloud (AWS) * Ownership mindset: autonomy, proactivity, and focus on delivering value with technical accountability **Nice-to-have** * Microservices architecture and messaging (AWS SNS/SQS) * Docker and Kubernetes * NoSQL databases and caches/queues: Redis, DocumentDB, DynamoDB * CI/CD experience (e.g., GitHub Actions, Argo CD) * Spanish (not mandatory) * TypeScript knowledge * Flutter knowledge **Additional information** **Work model** * Remote work. * International interactions exclusively via written communication. * Fluency in other languages is not required, but is considered a plus. **Here, we are \#SangueLaranja!** We have been in the market for 17 years, side by side with our clients, delivering transformative experiences. We are a global technology and innovation ecosystem; beyond Brazil, we operate in Europe and the UK, with offices in Portugal, London, Dubai, and the Netherlands. **F for Formation: we believe in sharing culture, community spirit, and that knowledge** **has the power to transform!** We run initiatives and social actions promoting development, such as the tech community Orange Juice, the Training Program, our leadership school, and numerous partnerships with NGOs and Edtechs. **At FCamara, everyone is welcome — for us, Diversity, Respect, and Ethics are non-negotiable elements embedded in our DNA.** **So, are you ready to join an amazing team and become the protagonist of your own story?
