This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Desenvolvedor(a) Full Stack Sênior (Node.js, PHP & React) based in Brazil. Join a technology consulting environment where software engineering, data, and artificial intelligence come together to solve complex business challenges. As a Senior Full Stack Developer, you will take ownership of production support requests, investigate technical issues, and deliver effective solutions across backend and frontend systems. You will also contribute to new features and continuous improvements using Node.js, PHP/Laravel, and React.js. AI-powered development tools, including Claude and Claude Code, will be an integral part of your workflow, helping you accelerate debugging, coding, testing, and documentation. Working closely with technical teams, business stakeholders, and requesters, you will ensure clear communication, reliable delivery, and a positive support experience. This opportunity is ideal for an autonomous, proactive engineer who enjoys solving problems, improving applications, and sharing innovative practices with the team.

Production support and troubleshooting: Manage support requests from initial investigation through resolution, identifying root causes and implementing fixes across backend and frontend applications. End-to-end ownership: Take responsibility for assigned tickets, independently gathering the necessary information, coordinating activities, and ensuring issues are resolved efficiently. Stakeholder communication: Keep requesters, business stakeholders, and leadership informed through clear updates on progress, expected timelines, business impact, risks, and potential blockers. Full stack development: Build, maintain, and enhance applications using Node.js for backend services, PHP/Laravel for server-side development, and React.js for frontend functionality. Feature development and continuous improvement: Deliver new features and technical enhancements that improve application functionality, performance, reliability, and maintainability. AI-assisted engineering: Use tools such as Claude and Claude Code to accelerate technical investigations, generate and refine code, review implementations, and produce documentation. Code quality and collaboration: Participate in code reviews, follow established pull request workflows, and comply with team standards for testing, integration, and deployment. Incident documentation: Record the root causes, troubleshooting steps, and solutions associated with support requests to improve knowledge sharing and prevent recurring issues. Operational efficiency: Identify recurring problems and recommend technical or process improvements that reduce support volume and increase system stability. Database management: Investigate database-related issues, optimize queries, and contribute to data modeling and performance improvements. Agile delivery: Manage changing priorities while balancing production support responsibilities with feature development in a Kanban-based workflow. Continuous learning and innovation: Explore emerging AI tools and development techniques, evaluate their practical value, and share effective approaches with the wider team. Requirements More than 6 years of professional software development experience , with substantial experience working across the full stack. Strong backend development skills with Node.js , including the design, development, and maintenance of REST APIs. Practical experience with PHP and Laravel for backend application development and maintenance.
