Full Stack Developer (Platform & Multi-Tenant Systems)

At Robots & Pencils, we build meaningful, scalable software experiences that help innovative organizations move faster and smarter. We are seeking a Full Stack Developer to support the development and delivery of a complex, multi-tenant, integration-heavy platform. 

This role is ideal for an experienced engineer who thrives in hands-on development, can confidently own features and deployments, and contributes to system design and delivery within a pod. 

In this role, you will work as a key contributor on a cross-functional team, building across the stack while helping guide delivery, improve systems, and solve challenging integration problems. You’ll partner closely with Product, Design, and Engineering teammates to ensure high-quality, scalable solutions reach production. 

 

Why This Role Matters 

At Robots & Pencils, we build smart systems for the human world. This role plays a critical part in making that real by connecting platforms, enabling seamless user experiences, and ensuring the systems behind them are reliable and scalable. 

You are not just shipping features; you are helping shape how systems integrate, how multi-tenant platforms operate securely, and how products evolve—contributing directly to meaningful outcomes for users and clients.
