Software Engineer, Backend

ABOUT WISPR

Wispr Flow is making it as effortless to interact with your devices as talking to a close friend.

Today, Wispr Flow is the first voice dictation platform people use more than their keyboards — because it understands you perfectly on the first try. It’s context-aware, personalized, and works anywhere you can type, on desktop or phone.

In 2026, in addition to dictation, we're focused on building native actions — an agentic framework that understands you, and works reliably.

We’re a team of AI researchers, designers, growth experts, and engineers rethinking human-computer interaction from the ground up. We value high-agency teammates who communicate openly, obsess over users, and sweat the details. We thrive on spirited debate, truth-seeking, and real-world impact.

We've grown our revenue +150% every quarter for the last 4 quarters, and have raised $81M from Tier 1 VC firms and other well-known angels.

ABOUT THE ROLE

As a Software Engineer, Backend, at Wispr, you’ll play a crucial role in building the first capable, habit forming voice interface that scales to a billion users. Members of our technical staff are responsible for prototyping and designing new features of our voice interface, building infrastructure to handle <500ms LLM inference for millions of requests from everywhere around the world, and scaling the personalization of our speech models and LLMs.

WHAT YOU'LL DO

- Build and own core backend systems, APIs, data pipelines, and infrastructure that power Wispr's dictation and agentic features across desktop and mobile

- Design for reliability, security, and scale, owning services end-to-end from initial architecture through production performance and incident response

- Collaborate closely with ML engineers to integrate and ship model improvements into production, fast

- Instrument systems for observability (logging, metrics, alerting) so we can understand how things are working and catch problems early

- Use AI...
