## Responsibilities

- Define and Own Growth Metrics: Establish and maintain the key performance indicators (KPIs) the growth team is accountable for, spanning the entire user funnel from initial sign-up and trial activation through premium upgrade conversion. Work with senior leadership and product teams to align metrics with business objectives and ensure they accurately reflect user value and engagement.
- Analyze User Behavior and Telemetry: Conduct deep dives into product telemetry, user behavior patterns, and external signals including community forums, social media, and video comments to identify friction points, adoption barriers, and drop-off moments. Transform raw data into actionable insights that inform engineering priorities and experiment hypotheses.
- Design and Execute A/B Tests: Formulate testable hypotheses based on user research findings, then independently design, build, ship, and analyze A/B tests that validate solutions. Measure statistical significance, interpret results, and iterate rapidly to optimize conversion funnels and user activation pathways across the platform.
- Develop Full-Stack Production Code: Own end-to-end implementation across the full technology stack from frontend landing pages and onboarding flows to backend services and APIs. Ship production code in TypeScript, React, and modern backend frameworks without handoffs, maintaining quality and performance standards across distributed systems.
- Leverage AI Coding Agents for Velocity: Utilize AI-powered coding agents as collaborative team members to accelerate development cycles from concept through production deployment. Maintain expertise in AI-native workflows, prompt engineering, and agentic architecture to maximize productivity and code quality while maintaining architectural integrity.
- Communicate Results to Cross-Functional Leadership: Present experiment design, hypotheses, outcomes, and learnings to engineering, product, design, and executive stakeholders through clear written reports and compelling presentations. Build data-driven narratives that contextualize technical implementation within broader business strategy and influence decision-making.

## Full description
# **Life at UiPath**

The people at UiPath believe in the transformative power of automation to change how the world works. We’re committed to creating category-leading enterprise software that unleashes that power.

To make that happen, we need people who are curious, self-propelled, generous, and genuine. People who love being part of a fast-moving, fast-thinking growth company. And people who care—about each other, about UiPath, and about our larger purpose.

Could that be you?

## About the role

Millions of people meet UiPath for the first time through a sign-up page, a template or a first automation, and this role owns what happens next. Your job is to find out why people adopt, stick with or drop our products, then build and ship the changes that move those numbers.

This is an engineering role first. You'll write production code across our platform, from the first landing page to the moment someone publishes their first automation. You'll also do the product thinking: picking which problem to solve, defining what success looks like, and proving it with data.

## What you'll do

* Help define the growth metrics the team owns, from sign-up and trial activation through to upgrade.
* Study product telemetry and public signals (community forums, social media, video comments) to find where users get stuck and why.
* Turn each finding into a testable hypothesis, then build, ship and A/B test the fix yourself.
* Work in any part of the codebase that a fix needs, rather than handing it off to another team.
* Use AI coding agents as your team, taking ideas from concept to production quickly.
* Explain each experiment clearly to engineering, product, design and leadership: why you ran it, what success meant, and what you learned.

## What you bring

* Principal-level engineering experience, with recent hands-on work shipping full-stack production code (TypeScript, React and backend services, or similar).
* An AI-native way of building: you use coding agents every day and can describe your workflow in detail.
* A track record in growth, activation or funnel work at a product-led company, with metrics you personally moved.
* Strong product sense: you find the problem, propose the solution and decide how to measure it, without waiting for a spec.
* The ability to move fast with a small footprint. You've delivered real results without a large team behind you.
* Clear written and spoken communication, including making a case to senior leaders.

## Nice to have

* Growth experience at an enterprise product-led company where self-serve users turn into business customers.
* Experience optimizing for AI agents as users, such as agent-friendly docs, APIs and discovery.
* A public presence: talks, posts, open source or content that developers actually read.
* Familiarity with automation, workflow or developer-platform products.

## Why this role

You'll be a founding engineer on a high-visibility team, working directly with senior engineering and product leaders. You'll have the freedom to act as the mini CTO of your own ideas, building on the newest parts of UiPath's agentic automation platform and reshaping how people discover and adopt it. What you ship will show up quickly in the numbers the whole company watches.
