About the role and Team

At Amplitude, millions of developers instrument their products to understand how users behave. The first code they write with Amplitude is almost always through an SDK. That means our SDKs are not just integrations, they are the developer experience of Amplitude itself. We're building a new kind of SDK team:

Most companies hire SDK engineers per language.

We don't.

We're recruiting AI-assisted SDK wizards , engineers who:

• learn new languages quickly

• Use AI to scale SDK development - build systems that allow a small team to maintain many SDKs
• Own developer experience - improve how developers integrate with Amplitude
• Optimize SDK for latency, performance, bundle size, resource load
• Create external-facing agents that take advantage of the signals collected by our SDKs
• Build integrations with third parties
• Drive high engineering standards while knowing when speed beats perfection.
• Create a culture where people love the work, move fast, and deliver real outcomes.

You Might Be a Great Fit If:

• Experience building SDKs, APIs, or developer platforms.
• Open source library maintainership
• Experience across multiple language ecosystems
• Interest in developer experience and tooling
• Experience building platform tooling or code generation systems

Why This Team, Why Now?
