Job description

• The Claude Platform serves developers and enterprises at scale. The Developer Experience (DevX) team owns the surfaces those developers touch every day: the Console, the docs platform, and our SDKs and CLI
• Our job is to make the Platform easy to adopt and trustworthy enough to build critical applications on, to get new model and API capabilities into developers’ hands fast and ergonomically, and to build for both humans and the coding agents that increasingly use our docs and SDKs on their behalf
• The work splits into two workstreams, covered below, and we need your help across both
• DevX Core: You’ll help drive technical direction for the Console and docs platform — the surfaces every developer on the Claude Platform uses — working with product and design from problem definition through launch. The Console is also the front door for tens of internal teams shipping their own features onto it, so you’ll set the platform patterns and standards they build against
• SDKs: You’ll own the SDKs across seven languages plus our CLI — the first thing most developers (and most coding agents) touch when they integrate Claude. You’ll partner with API teams early so every new platform capability lands in the SDKs as an idiomatic, ergonomic feature on day one, and you’ll drive the code generation, testing, and release pipeline that keeps seven languages consistent and shipping fast

• Care deeply in investing in the mentorship and growth of your peers.
• Have worked in early start-up or otherwise fast moving, rapidly evolving environments, and have ideally built products from 0 to 1.
• Have experience establishing engineering standards, component architectures, and development best practices.
• Have led the design and delivery of complex, developer-facing products across the full stack.
• Have a minimum of 8 years of practical full-stack engineering experience, ideally with 2+ years operating at a Staff or equivalent technical leadership level.
• Take a product-focused approach to building solutions that are robust, scalable, and easy to use.

• Have successfully driven cross-team/cross-org organizational alignment to get impactful work shipped, and work with influence over authority.
