At Robots & Pencils, we build meaningful, scalable digital products that solve real business problems. We’re looking for a Fullstack Engineer (Level 3) to support the development and delivery of complex, integration-heavy platforms. This role is ideal for a solid engineer who enjoys hands-on development, can deliver features with some guidance, and is growing into owning larger parts of the system. In this role, you will work as part of a cross-functional team, contributing across the stack while helping build reliable systems and solve integration challenges, including AI-native platforms such as agentic learning systems designed to enable human-centered learning in the Age of AI. 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 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 (and some Python), including serverless architectures (e.g., AWS Lambda, API Gateway) Develop and integrate APIs that support frontend applications and external systems Contribute to frontend features and ensure smooth integration across the stack Write clean, maintainable, and well-tested code with solid unit testing practices Workflow & System Orchestration Contribute to workflows using orchestration tools (e.g., workflow engines, state machines) Support event-driven processes and asynchronous system operations (e.g., SQS, EventBridge) Help improve system reliability through error handling and retries Backend & API Engineering Develop RESTful APIs and contribute to backend architecture Integrate with third-party services and internal systems, including AI-driven platforms Assist in optimizing performance and scalability of services (e.g., DynamoDB patterns) Follow secure and reliable data handling practices System Reliability & Support Troubleshoot issues in production environments with support from senior team members Contribute to logging, monitoring, and debugging efforts Assist with deployment and release processes in cloud-native environments (AWS, Docker) Collaboration & Growth Work closely with cross-functional teams across global locations Participate in code reviews and team discussions Deliver assigned features end-to-end with guidance Continue developing technical skills, including AI-assisted development tools Required Skills & Experience 3–5 years of professional software engineering experience Strong experience with Node.js Experience building and maintaining fullstack applications Basic to intermediate experience with cloud environments (AWS preferred) Familiarity with API design and backend systems Familiarity with databases (SQL and/or NoSQL) Experience working in production environments Solid unit testing practices Experience with containerization (e.g., Docker)

Nice to Have

Experience with Python Exposure to event-driven architectures Familiarity with AWS services (Lambda, DynamoDB, S3, SQS, etc.) Exposure to workflow orchestration tools Exposure to AI/LLM-based systems (e.g., LangChain, LangGraph) Experience with CI/CD pipelines and infrastructure-as-code tools (e.g., CDK) Experience working in collaborative, distributed teams 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. If you enjoy building across the stack, solving real integration challenges, and growing within a high-performing, globally distributed team, we’d love to meet you.
