Staff Full Stack Engineer

APPLICATIONS FROM OUTSIDE COLOMBIA WILL NOT BE CONSIDERED FOR THIS ROLE Robots & Pencils is an applied AI engineering firm building the next frontier of business architecture. We design and ship AI co-workers that integrate into enterprise operations and deliver measurable results for our clients. We're all in on AWS, combining deep UX capability with senior engineering talent to get AI into production fast and keep it there. We’ve earned the trust of leaders across Consumer Products and Retail, Education, Energy, Financial Services, Healthcare, and Manufacturing and more, and earned a reputation as the nimble alternative to traditional global systems integrators. Founded in 2009, with delivery centers in Canada, the United States, Eastern Europe, and Latin America, we are smaller, faster, and more senior by design. Our teams average 15+ years of experience. We move fast, sweat the details, and build things that actually ship.Position OverviewWe’re looking for a Staff Full Stack Engineer to lead the design and delivery of complex, integration-heavy platforms. This role is ideal for an experienced engineer who can define front-end architecture and technical strategy, lead complex UI systems development, and confidently own large parts of the system end-to-end.In this role, you will work as a key technical contributor on a cross-functional team, defining standards and best practices, building scalable systems, and solving complex integration challenges. You’ll mentor more junior engineers, collaborate closely with senior engineers and leadership, and deliver high-quality work where reliability, performance, and scalability are critical.Why This Role MattersAt Robots & Pencils, we design AI systems for a human world. Our name says it all. Robots and pencils means engineering paired with creativity, because every agent we ship has to work for real people in real workflows. That balance is baked into how we operate. Every role here contributes directly to that mission. Here, you shape how AI systems integrate into enterprise operations, how teams move at real velocity, and how products create measurable impact for clients and the people they serve. We ship production-ready AI in 30 to 45 days. That pace demands people who take ownership, lead with craft, and care deeply about what they put their name on.What You’ll DoCraft & DeliveryDefine front-end architecture and technical strategy, designing scalable platforms and leading complex UI systems development (e.g., React, Angular, Next.js, TypeScript)Define front-end standards and best practices, and contribute to shared design systemsLead back-end development and API architecture, integrating complex systems and third-party platforms (e.g., Node.js, Python)Design efficient database schemas and optimize performance across relational and NoSQL systemsDrive backend performance, scalability, and reliability, and own implementation of security best practices including authentication and authorizationLead monitoring, observability, and reliability practices across production systemsLead the design and integration of AI services into production full-stack systems, including LLM APIs, streaming, tool and function calling, multi-step agent flows, and RAG patternsBring an AI-forward mindset to your daily work, using tools like Claude, Cursor, and other modern AI assistants to ship higher-quality work at paceCollaboration & CommunicationCollaborate closely with cross-functional teams to align technical decisions with product and business goalsCommunicate complex technical tradeoffs and architectural decisions clearly across engineering and non-engineering stakeholdersLead code reviews and design discussions, raising the quality bar for the teamLeadership & InfluenceEstablish front-end and full-stack engineering standards that lift quality and consistency across the teamMentor junior and mid-level engineers, helping them grow their craft, confidence, and impactMake architectural decisions with thoughtful consideration of tradeoffs and long-term implicationsWhat You’ll Bring7+ years of professional software engineering experience, with experience leading complex full-stack initiativesDeep proficiency in React or Angular with strong JavaScript and TypeScript skills (e.g., React, Angular, Next.js)Strong experience with state managementStrong command of modern CSS frameworks and build toolingStrong back-end development and API architecture experience (e.g., Node.js, Python)Strong testing practices across unit, integration, and UI testingDeep expertise in relational and NoSQL databases, caching, and query optimizationStrong experience with microservices architecture, event-driven systems, and message queuesStrong experience with cloud platforms and container orchestrationStrong experience with CI/CD pipelinesStrong experience integrating AI services into production full-stack systems, including LLM APIs, streaming, tool and function calling, multi-step agent flows, and RAG patt
