The UI Foundation team owns the frontend infrastructure that every product engineer at Amplitude builds on — architecture, performance, developer experience, tooling, and build systems. We're the team that makes shipping fast, reliable frontend code possible at scale, and we're increasingly focused on how AI agents can autonomously handle engineering workflows that used to require constant human intervention.

We're looking for a Staff Software Engineer who thinks like an infrastructure engineer but has deep fluency in frontend systems. You'll drive architectural decisions for our frontend platform, push performance and DevX forward, and lead the build-out of our "software factory" — a set of autonomous, AI-agent-driven engineering workflows that increase engineering velocity across the org.

This is a high-leverage, low-oversight role. You'll be setting technical direction for a foundational team, not just executing a roadmap someone else wrote.

Frontend architecture: Own and evolve the architectural foundations of our frontend platform — module boundaries, micro-frontend patterns, shared component/design-system infrastructure, and state management strategy.

Application performance: Diagnose and fix systemic performance issues (bundle size, load time, runtime performance, rendering bottlenecks); establish performance budgets and guardrails that scale across teams.

Developer experience & tooling: Build and maintain the build systems, local dev environments, CI/CD pipelines, linting/codegen, and internal tooling that other engineers depend on daily.

Software factory / agentic workflows: Continuously identify the biggest bottleneck in the engineering workflow and build AI-agent-driven automation to remove it, then move to the next one. For example, once code and PR generation stopped being the constraint, the bottleneck shifted to validation — and that's the next thing to automate. This is an ongoing, iterative practice of finding where engineers are spending unnecessary manual effort and systematically eliminating it with agentic tooling.

Technical leadership: Set technical direction and standards for the frontend org; mentor senior/staff-track engineers; review architecture proposals from other teams that touch shared frontend infrastructure.

Cross-functional partnership: Work closely with product engineering teams, design systems, and platform/infra teams to make sure foundational investments actually solve real product-team pain points.

The Company:Amplitude is filled with humble, life-long learners who are eager to help one another and the company succeed. Our values of growth mindset, ownership, and humility are core to the way we work: we’re tenacious in the face of challenges, we take the initiative to solve problems that drive our shared success, and we operate from a place of empathy and openness, seeking to understand many points of view.

The Product:Amplitude is a digital analytics platform—we help companies capture data they can trust, uncover clear insights about customer behavior, and take faster action. This empowers teams to build better product experiences that drive business growth. We’re super proud of what we’ve built and continue to expand: a platform that empowers companies to thrive in the digital era.
