As an organization, we approach challenges with humility, take ownership of our contributions, and embrace a growth mindset that pushes us to constantly improve ourselves, each other, and the value we bring to customers and partners. Amplitude’s Commitment to Diversity Equity & Inclusion (DEI): Amplitude believes that diversity enables the creation of better products, improves the ability to solve complex problems, and drives more powerful solutions. We strive to create an environment of inclusion—one focused on psychological safety, empathy, and human connection—that will allow employees of all backgrounds to thrive. We’re building AI interfaces that don’t suck. The AI Team at Amplitude is creating new product experiences powered by intelligent agents — but we care just as much about how they show up in the UI as we do about the backend. If you’ve ever used an AI product and thought, “Why is this so unhelpful” you’re in the right place. This role is for a fullstack engineer who leans frontend, has a strong product sense, and cares deeply about quality. You’ll own experiences end-to-end, from system design to pixel polish, and help define what “usable” AI feels like. You’ll be part of a small, scrappy, high-context team working across the entire LLM stack — from prompt design to infra to monitoring to customer-facing UX. We move fast, own our work, and prioritize quality + learning over throwing models at the wall. It’s ambitious, but we think this team has the potential to build something that becomes bigger than Amplitude’s core business in a short period of time. And we have the support of the company to do that.
