Why This Job is Featured on The SaaS Jobs
This Senior Software Engineer role sits in a core SaaS category where product analytics meets experimentation. Building on Amplitude’s Experiment offering places the work close to how modern SaaS companies validate changes, measure impact, and operationalise decision-making across digital products. The remit spans customer-facing workflows and the underlying systems that make test results reliable, which is central to trust in any experimentation platform.
From a SaaS career perspective, the role develops a blend of product engineering and platform thinking that transfers well across B2B software. Owning end-to-end surfaces encourages fluency in the full lifecycle that matters in subscription products: shipping, observing real usage, iterating, and maintaining quality as adoption grows. Exposure to cross-functional product direction and to AI-assisted development practices also maps to how many SaaS teams are evolving their delivery models.
This role is best suited to an engineer who prefers ownership over narrowly scoped execution and who enjoys turning ambiguous product goals into shippable systems. It aligns with someone comfortable moving between UX details and backend trade-offs, and who values measurable outcomes and rigorous engineering judgment in a data-driven environment.

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