Staff Full Stack Engineer
About the role
Position Overview
We'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 build and integrate across channel surfaces including chat, voice, and web, craft front-end experiences for client demos and prototypes, 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 Matters
At 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. You'll build the integrations that connect AI to real channel surfaces, and the demos and prototypes that bring those systems to life in front of decision-makers. 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 Do
Craft & Delivery
- Define front-end architecture and technical strategy, designing scalable platforms and leading complex UI systems development (e.g., React, Angular, Next.js, TypeScript)
- Build polished, demo-ready front-end experiences that communicate the value of AI systems to clients and stakeholders
- Define front-end standards and best practices, and contribute to shared design systems
- Lead back-end development and API architecture in Python and Node.js, integrating complex systems and third-party platforms
- Design and implement channel integrations across chat, voice, and web surfaces, including real-time messaging, webhook pipelines, and event-driven patterns
- Design efficient database schemas and optimize performance across relational and NoSQL systems
- Drive backend performance, scalability, and reliability, and own implementation of security best practices including authentication and authorization
- Lead monitoring, observability, and reliability practices across production systems
- Lead 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
