Full Stack Engineer (TypeScript & Node.js)

About You

You are a Full Stack Developer with a strong backend and TypeScript orientation, passionate about building scalable, reliable, and high-performance web applications. You thrive in fast-paced environments where requirements evolve, and you take ownership of delivering robust end-to-end solutions with minimal direction.

You are proactive, curious, and comfortable navigating ambiguity. You enjoy architecting APIs and cloud-native services as much as building clean, data-rich user interfaces, and you care deeply about performance, security, and code quality across the entire stack.

Note: This position is offered under a contractor model for a period of 9 months.

You Bring to Applaudo the Following Competencies:

• Bachelor’s Degree in Computer Science, Software Engineering, Computer Engineering, or a related field is desired, or equivalent professional experience.
• 6+ years of experience as a Full Stack Developer, with a strong emphasis on backend development using TypeScript and Node.js.
• Strong proficiency in TypeScript across both frontend (React, Next.js) and backend (NestJS) environments.
• Solid experience designing and building RESTful and GraphQL APIs, with a focus on performance and maintainability.
• Solid experience deploying and operating services in serverless environments (AWS Lambda).
• Strong knowledge of PostgreSQL, Supabase, and SQL, including query optimization and data modeling.
• Strong proficiency in React and Next.js, with experience building data-heavy interfaces such as dashboards, tables, and visualizations.
• Familiarity with Tailwind CSS and component-driven UI development.
• Experience writing and maintaining unit and integration tests using Jest.
• Familiarity with authentication and authorization tools such as Auth0 (Microsoft Entra is a plus).
• Hands-on experience with AWS services, especially Lambda and ElastiCache.
• Experience with caching strategies, background jobs, and asynchronous processing patterns.
• Experience deploying and managing applications using Vercel or similar platforms.
• Familiarity with tools like AgGrid or similar data grid libraries (nice to have).
• Strong understanding of software development best practices, including code quality, testing, and performance optimization.
• Strong communication skills and advanced English proficiency, working with US-based stakeholders.

You Will Be Accountable for the Following Responsibilities:

• Design, develop, and maintain scalable backend services and APIs with a strong focus on performance, reliability, and security.
• Build and optimize data-intensive backend processes, including complex queries, aggregations, and third-party integrations.
• Develop and maintain React and Next.js frontend interfaces, with emphasis on data-heavy components such as dashboards, tables, and visualizations.
• Collaborate with cross-functional teams to define, build, and ship product features across the full stack.
• Design and implement GraphQL and REST APIs, ensuring efficient data handling and seamless frontend integration.
• Write clean, maintainable, and well-tested code before submitting pull requests, upholding high code quality standards.
• Identify and resolve blockers proactively, communicating progress and risks clearly to stakeholders.
• Navigate ambiguous requirements by making informed architectural decisions and validating assumptions with the team.
• Participate in technical discussions and contribute to both backend and frontend architecture decisions.
• Manage tasks effectively within a Kanban workflow.
