What is a Software Engineer at Superhuman?
At Superhuman, we are building the fastest email experience in the world. As a Software Engineer, you do not just write code; you craft an interface where every interaction happens in under 100 milliseconds. This relentless focus on speed, responsiveness, and delightful user experiences makes engineering at Superhuman uniquely challenging and rewarding. You will work on a highly optimized, offline-first client architecture that synchronizes millions of data points seamlessly with backend services, ensuring that users can fly through their inboxes without a single hitch.
The engineering team is organized around deep craft and high ownership. Whether you specialize in frontend engineering (leveraging React, TypeScript, and native browser capabilities to build keyboard-shortcut-driven UIs) or backend systems (building ultra-fast synchronization engines, robust APIs, and local database integrations), your work directly impacts user productivity. You will solve complex problems related to local data persistence, real-time synchronization, memory management, and rendering optimization.
To succeed in this role, you must possess a strong foundation in computer science, a passion for performance tuning, and a high degree of product empathy. Superhuman engineers are expected to think deeply about user workflows and build systems that are not just functionally correct, but exceptionally fast and reliable.
