About The Position

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. 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.

Requirements

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 Haves

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

Responsibilities

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)
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
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
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
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
