Job description

Amplitude is a leading AI analytics platform that helps customers build better products and digital experiences.

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: AI‑assisted SDK wizards, engineers who build tooling to scale SDK maintenance and own developer experience end‑to‑end.

This role has unusually large scope and autonomy.

What You'll Work On

• 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, and 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
• 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 Amplitude

Our values

• Humility – we operate from empathy and openness
• Ownership – we take initiative to solve problems that drive company success
• Growth Mindset – tenacious handling of challenges and seeking feedback
• Customer Centricity – putting the customer at the center of everything we do

Benefits

• Excellent medical, dental, and vision insurance with 100% employer‑paid premiums on select plans
• 401(k) retirement plan with up to 1% employer‑match of eligible pay each period, up to $2,000 annually
• Flexible time off, paid holidays, and more
• Generous stipends for wellness, commuter transit/parking, learning and development, new hire home office equipment, etc.
• Excellent parental benefits – 12 weeks paid leave, fertility/ adoption/ surrogacy support, backup child care
• Mental health and wellness benefits, no cost employee access to Modern Health coaching & therapy sessions
• Mentorship programs, management training, and wellness initiatives
• Charitable giving grant and paid volunteer time off
