Sanas•Palo Alto, CA

About The Position

We are looking for a Developer Platform Engineer to own and build the developer-facing surface of Sanas end-to-end. This is a founding-level role: you will be the first person fully dedicated to owning this platform, shaping everything from the API contract to the SDK to the docs to the console. This is a builder role, not an oversight role. You will write code, author docs, ship the SDK, and own the console. This is a role intended for a true builder/creator.

Requirements

5+ years of software engineering experience
At least 2 years of experience on developer-facing products (APIs, SDKs, developer tools, or platform infrastructure)
Shipped a public-facing SDK end-to-end, owning versioning, deprecation, and the full release lifecycle
Ability to design a REST or WebSocket API from scratch (naming, error contracts, pagination, versioning)
Experience dealing with breaking API changes in production
Full-stack capable: comfortable enough in React to build the Developer Console without a frontend specialist, while also owning the backend services behind it
Strong engineering taste: ability to enforce high standards in code review, API design, and SDK ergonomics
Comfortable making decisions, moving fast, and pulling in others when needed

Nice To Haves

Experience with real-time audio, WebRTC, or streaming media APIs
Prior work at a developer tools company, speech AI company, or infrastructure startup where developer experience was a first-class concern
Familiarity with on-device or edge deployment models
Experience building or operating self-serve developer portals with usage-based billing, quota management, or tiered access
Personal experience integrating a voice or audio SDK into a production product

Responsibilities

Design, implement, and maintain idiomatic SDKs for Sanas's real-time Speech AI APIs, including streaming support, robust error handling, automatic retries, type safety, and a DX-first design.
Own versioning, deprecation, and changelog for SDKs.
Own the design of the public API surface: naming conventions, versioning strategy, error codes, response shapes, and pagination.
Partner with the technical writer to ensure reference documentation reflects the spec accurately.
Build and evolve the web-based developer portal, including API key management, usage and analytics dashboards, credential provisioning flows, and environment management.
Own both the frontend and the backend APIs that power the developer console.
Own the technical accuracy of all published documentation.
Define what needs to be documented, review for correctness, and ensure the information architecture reflects how developers actually integrate Sanas.
Continuously improve the end-to-end journey from first API call to production deployment.
Act as the internal voice for developer clarity across every surface Sanas exposes externally.
