Software Engineer, Back-End - Advanced Voice Input

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.

• 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 future.

• Experience with scalability and reliability of back-end services, including building observability systems and maintaining large-scale systems in production.
• A track record of building and shipping features within services that handle a high volume of usage.
• Some experience working with AI coding tools.
• Strong product intuition — the ability to identify and prioritize solutions to problems that matter most to users and the product.
• Has a demonstrated ability to work independently with minimal guidance, proactively manages tasks and priorities across multiple projects, analyzes and executes work efficiently, collaborates effectively with cross-functional teams, and thrives in fast-paced, results-driven environments.

• Professional Growth: We believe that autonomy and trust are key to empowering our team members to do their best, most innovative work in a way that aligns with their interests, talents, and well-being
• A connected team: Superhuman builds a product that helps people connect, and we apply this mindset to our own team. Our remote-first, hybrid model enables a highly collaborative culture rooted in our values. We work to foster belonging among team members in a variety of ways. This includes our team member resource groups, Superhuman Circles, which promote connection among those with shared identities including BIPOC and LGBTQIA+ team members, women, and parents. We also celebrate our colleagues and accomplishments with global, local, and team-specific programs.
• Comprehensive benefits for candidates based in Germany: Superhuman offers all team members competitive pay along with a benefits package encompassing life care (including mental health care and risk benefits) and ample and defined time off. We also offer support to set up a home office, wellness and pet care stipends, learning and development opportunities, and more.
• Relocation Support: Superhuman provides relocation support to make your move to Berlin seamless. Our package includes visa assistance, destination services to help you and your family settle in comfortably, and a relocation bonus to cover additional expenses, such as temporary housing.
