Job description

Experiment is one of the fastest-growing and most strategic bets at Amplitude. It sits at the intersection of product, data, and decision-making, and we’re looking for a Senior Product Engineer to help take it to the next level.

Why this role matters

This isn’t a “take tickets and ship code” role. You’ll operate as an owner, shaping both the product and the technical direction of a system used by some of the most sophisticated product teams in the world.

You’ll work across the stack, React frontend, Node.js and Python backend, to build intuitive, high-performance experiences that make experimentation accessible, powerful, and trustworthy.

What you’ll do

• Own critical product surfaces end-to-end from ideation to production and beyond
• Drive product direction in partnership with design and product leaders
• Build and evolve systems across React, Node.js, and Python that scale with customer growth
• Leverage modern AI tooling to dramatically accelerate development, prototyping, and iteration cycles
• Raise the bar for engineering quality - code, architecture, and user experience
• Lead by example - through hands‑on development, technical mentorship, and thoughtful decision‑making
• Move fast on ambiguous problems, turning ideas into shipped, customer‑facing value

What we’re looking for

• 5+ years of experience in software engineering
• Education: B.S. in Computer Science or an equivalent technical field
• Proven experience operating at a senior‑level scope. You’ve led large, ambiguous initiatives with significant business impact
• Strong full‑stack expertise (React + backend systems such as Node.js and/or Python)
• A deep sense of ownership - you don’t wait for direction; you create it
• Exceptional product taste - you care deeply about UX, details, and building things people love
• An AI‑native mindset - you actively use and experiment with the latest AI tools to amplify your impact and rethink how software gets built
• Ability to balance speed and quality in a high‑velocity environment
• Strong judgment in technical trade‑offs and system design

What sets you apart

• You think like a product builder first, engineer second
• You’re constantly reinventing how you work, using cutting‑edge tools and workflows to achieve outsized results
• You’re energized by open‑ended problems with no clear “right” answer
• You hold a high bar, not just for your own work, but for the team and product as a whole
• You turn ambiguity into clarity and momentum

Why Amplitude

• Work on a product used by thousands of companies to make better decisions
• Be part of a team that’s expanding beyond analytics into a full digital optimization platform
• Join a culture that values ownership, velocity, and craft
• Have outsized impact on a top company priority
