The Opportunity To achieve our ambitious goals, we're looking for a Software Engineer to join a fairly new team building an entirely new product within the company: Advanced Voice Input . Our mission is to enable users to work with their devices and AI agents through voice and to make people more productive by using voice as a primary input. The team's key focus is developing the internal services and front-end SDKs that process voice and translate it into text, commands, or whatever the user needs. The primary focus area is a back-end service written in Go that handles all user connectivity, calls voice models, post-processes output, and manages the quality of our voice engine. You'll join a fairly small team as a back-end engineer, focused on building new features and improving the service's quality and reliability. Like other engineers at Superhuman, you're expected to own your solutions end-to-end — from concept to implementation to maintenance. We're looking for someone with an open mind and curiosity toward using AI-coding tools while building this service. This is a rare opportunity to help define a brand-new product from the ground up, with plenty of room for ownership and direct impact. As a Software Engineer, you will: Build and ship new features for a back-end voice-processing service, and improve its quality and reliability in production. Own solutions end-to-end — from concept and idea, through implementation and ongoing maintenance. Use AI coding tools with curiosity and help find ways to build reliable, automated development loops. Build and maintain observability into a large-scale, high-usage production system. Partner closely with engineers across multiple teams—including Mobile (iOS, Android), Browser Extensions, and Mac and Windows clients—to deliver a cohesive end user experience. Help shape a roadmap: explore directions, define experiments, and decide what to ship and when. Evaluate the systems and technology currently in place, and propose an architecture that can scale for the futur
