Full-Stack Senior Software Engineer

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
