At Robots & Pencils, we build meaningful, scalable digital products that solve real business problems. We’re looking for a Senior Fullstack Engineer to help build and maintain modern applications that integrate backend services, orchestration systems, and scalable APIs. You will work across the stack using Node.js, contributing to backend services and supporting frontend integrations while working within established architectures. This is not a greenfield project. You’ll be joining a mature, production environment with real users, where reliability, performance, and scalability are critical. You’ll collaborate closely with senior engineers to enhance existing systems and deliver high-quality features. By joining us, you leverage our Advanced AWS Partnership and the highly exclusive AWS Patterns Partnership, a distinction held by only 11 companies worldwide out of 190,000. What You’ll Do Fullstack Development Build and maintain backend services using Node.js, including serverless architectures (e.g., AWS Lambda, API Gateway) Develop and integrate APIs that support frontend applications and external systems, including institutional platforms and AI-driven services Contribute to frontend features using modern state management (e.g., Redux Toolkit with slices, async thunks, memoized selectors) and accessible, interactive UI patterns such as drag-and-drop with keyboard and screen reader support Write clean, maintainable, and well-tested code, maintaining high test coverage (90%+ across unit and integration tests) Workflow & System Orchestration Support the development and maintenance of workflows using orchestration tools (e.g., Sequencer / workflow engines, state machines) Contribute to event-driven processes and asynchronous system operations (e.g., message queues, distributed workflows) Assist in improving reliability through better error handling and retries Backend & API Engineering Develop RESTful APIs and support microservices architecture Integrate with third-party services and internal systems, including large-scale institutional data platforms Assist in optimizing performance and scalability of services using patterns such as NoSQL single-table design (composite keys, transactional writes) Implement secure and reliable data handling practices System Reliability & Support Troubleshoot issues in production environments with guidance from senior team members Contribute to logging, monitoring, and debugging efforts Support deployment and release processes in cloud-native environments Collaboration & Growth Work closely with cross-functional teams across global locations, contributing to large-scale platforms such as next-generation degree planning systems for university partners Participate in code reviews and team discussions Take ownership of assigned features and tasks, delivering end-to-end solutions from UI to API to database Continue developing technical skills and learning new technologies Required Skills & Experience 4–6 years of professional software engineering experience Strong experience with Node.js Experience building and maintaining fullstack applications, including delivering features end-to-end across frontend, backend, and data layers Exposure to workflow orchestration tools (e.g., Sequencer or similar systems) Solid understanding of API design and backend systems Experience working with cloud environments (AWS preferred), including serverless architectures Familiarity with databases (SQL and/or NoSQL, including scalable design patterns) Experience working in production environments Nice to Have Experience with Python Exposure to event-driven architectures Familiarity with AWS services (Lambda, SQS, Step Functions, etc.) Experience with CI/CD pipelines Exposure to AI/LLM-based systems and data-driven platforms Experience working in collaborative, distributed teams Experience building user-centric platforms with modern, accessible frontend architectures Why Join Robots & Pencils? At Robots & Pencils, you’ll join a global team of engineers, designers, and strategists who care deeply about craftsmanship, collaboration, and innovation. You’ll work on meaningful, production-grade systems that impact real users at scale, within a mature and evolving engineering environment. You’ll collaborate with experienced teams across backend, frontend, and infrastructure, gaining exposure to advanced AWS practices and modern architecture through our globally recognized partnerships. As part of a leading AI and cloud engineering organization, you’ll have the opportunity to grow your skills while contributing to high-impact digital products such as platforms that modernize user experiences through real-time, data-driven guidance. If you enjoy building across the stack, solving real integration challenges, and being part of a high-performing, globally distributed team, we’d love to meet you.
