Rallyuxr Senior Product Engineer at Rallyuxr leading end-to-end feature development for user research infrastructure. Collaborates cross-functionally to build AI-native product features that scale.
Responsibilities
We believe teams will always need to talk to their users, however far AI goes, and most companies still don't have a safe way to let team members outside of traditional UX Research do it. Rally Agent and MCP are live, and we're going after the biggest companies in the world. The product is catching up to the vision, with plenty of exciting challenges still ahead.
That's where you come in. You'd join our Product Engineering team, a small, high-ownership team that's a little obsessed with our users. You’d report to our Head of Engineering, and work side by side with the researchers and product builders who use Rally every day, and yes, we use Rally to build Rally.
Our product is the control plane for user research: the layer that enforces governance, permissions, consent, and contact rules for every agent that touches a company's participants. As a Senior Product Engineer, you’ll lead features end to end, from shaping the problem with Product and Design to shipping it and scaling it for some of the most demanding research teams in the world. Across each team at Rally, the work has the same core: building product in an AI-native environment, from core app features to the agents and MCP tools that power us.
Own features end to end: scope them with Product and Design, build them, ship them, and stay with them after launch to ensure reliability.
Scale features from MVP to enterprise grade, holding a high bar for security, privacy, reliability.
Work across the backend stack (Node, GraphQL, Prisma) and contribute to AI agent and MCP tool development to turn concepts into working product.
Work AI-first, using tools like Claude Code and Codex to move faster, while owning the quality and correctness of everything you ship.
Keep the team in the loop: write clear specs and updates, flag risks early, and share what you learn so the whole company gets better, together.
What you’ll bring
6+ years of experience architecting, building, and sustaining complex, production-grade web applications.
Strong full-stack engineering skills in JavaScript/TypeScript. You’re comfortable across the UI, API, and database layers, and you pick up new tools quickly.
Hands-on experience building with AI tools every day, plus a clear point of view on keeping quality high: how you review, test, and verify AI-generated work.

Preferred
Experience building AI agents, MCP tools, or backend services in an AI-native environment.
Experience working directly with customers, such as discovery calls, research sessions, or escalations.
Don’t check every box? Apply anyway. We care a lot more about what you can do than a perfect match to a list.
A heads-up before you apply
This is how we work, and we want to be transparent from the get-go, so you can decide if it’s the right fit:
Roles stretch here. Priorities shift as we learn, so you’ll often work outside a clearly defined lane.
You’ll own your work end to end. That means from the first idea through launch and beyond, rather than handing it off along the way.
We keep process light and teams small. You’ll have a lot of autonomy and fewer layers of support than at a larger company.
