Job Description
Team Lead Developer – Next.js, Node.js
Ruby Labs
• Hands-On Development. Actively build complex features and modules using Next.js and Node.js. You are not a manager who stopped coding - you are a developer who also leads. • Technical Ownership. Design system architecture, define the technology stack, and make key technical decisions. You are fully accountable for the quality, scalability, and reliability of the product. • Team Leadership. Lead, mentor, and push the development team. Run 1-on-1s, conduct code reviews, set high execution standards, and drive continuous improvement in delivery quality and speed. • Business Impact. Understand product and business goals and translate them into technical solutions that deliver real value. Propose improvements proactively - do not wait to be asked. • Process & Delivery. Implement and optimize Agile workflows - sprint planning, task estimation, delivery tracking. Ensure the team ships on time without accumulating technical debt. • Quality & Security. Enforce best practices in coding, testing, caching, and performance monitoring. Design and implement security measures at application, infrastructure, and data levels - including OWASP Top 10, CSP, CORS, and API hardening. • AI Integration. Research and integrate AI-driven solutions to improve the product and streamline development workflows. Practical experience with AI services (OpenAI API, LangChain, or equivalent) is expected. • Analytics & A/B Testing. Collaborate with the product team to integrate analytics systems and run A/B tests. Own the technical side of experimentation infrastructure.
