Job summary

Wispr Flow is building Flow, a voice‑driven product with a world‑class platform. You will help design and scale the underlying services that turn speech into action, improving performance and reliability for millions of users and thousands of enterprise customers.

The role focuses on end‑to‑end platform ownership, providing fast feedback loops for product engineers, and shaping the technical direction as the team expands from a small core to a larger, capable group.

Qualifications

• Experience building scalable backend platforms for latency‑sensitive systems.
• Strong design skills for distributed services and APIs.
• Track record of improving performance and reliability at scale.

Responsibilities

• Build the seam between product and ML: credentials, proxy, routing, experimentation.
• See the next scaling bottleneck two quarters early and fix it before anyone notices it existed.
• Architect and own whole parts of the platform end to end.
• Make every product engineer faster — dev experience, deploy speed, abstractions.
• Help set technical direction as the team goes from three to eight.
