Job description

About the role and Team At the company, millions of developers instrument their products to understand how users behave. The first code they write with the company is almost always through an SDK. That means our SDKs are not just integrations, they are the developer experience of the company 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 accelerate development

• build tooling to scale SDK maintenance

• own developer experience end-to-end

This role has unusually large scope and autonomy

What You'll Work On

• Build and maintain SDKs across many languages (e.g. TypeScript/JavaScript, Python, Go, Java, Swift, Rust)

• 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 the company

• 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?

• Huge scope - own SDKs used by thousands of developers
• Polyglot engineering - work across many ecosystems
• AI-augmented engineering - help define the future of SDK development
• Direct product impact - great SDKs drive adoption of the company

Our values:

• Humility: We operate from a place of empathy and openness, seeking to understand many points of view.
• Ownership: We take the initiative to solve problems that drive our shared company success.
• Growth Mindset: We’re tenacious in the face of challenges and seek feedback in order to grow ourselves and others.
• Customer Centricity: We put the customer at the center of everything we do and are deeply committed to their success.

We care about the well‑being of our team: We offer competitive pay and benefits packages that reflect our commitment to the health and well‑being of our Ampliteers.
