Job description

Amplitude is the leading AI analytics platform, helping over 5,200 customers—including Atlassian, Burger King, NBCUniversal, and Square—build better products and digital experiences. With powerful AI Agents embedded across our platform, teams can analyze, test, and optimize user experiences faster than ever. Ranked #1 across multiple categories in G2’s Winter 2026 Report, Amplitude is the best-in-class solution for product, data, and marketing teams. Learn more at amplitude.com.

As an organization, we deliver for our customers by living our values. We operate from a place of humility, take ownership of problems and successes, approach challenges with a growth mindset, and put our customers at the center of everything we do.

At Amplitude, we’re building the operating system for digital products. While we’re known as the leader in product analytics, our Statsig team is redefining how companies learn, iterate, and ship better experiences.

Statsig 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 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, NextJS and Node.js, 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 and Node.js 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
