Rallyuxr Senior Platform Engineer at Rallyuxr owning backend systems for governance, permissions, consent, and audit in user research infrastructure. Ensures reliability and correctness as the platform scales.
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 more people do it. 2026 is the year that's changing. Rally Agent and MCP are live, and we're going after the biggest companies in our space. The product is catching up to the vision, with plenty of hard problems still ahead.
That's where you come in. You'd join our Platform Engineering team: a small, high-ownership group that's a little obsessed with our users. We 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 our customers grow — more participant records, more concurrent studies, more agents running research workflows — that layer has to scale while staying provably correct, observable, and fail-closed. We need a platform engineer whose instinct is data integrity and customer-facing reliability first. You'll work across the databases, data pipelines, indexing, and orchestration that our biggest customers depend on every day — helping the team make those systems trustworthy enough that enterprises hand us their most sensitive participant data without hesitating.
Own and scale critical backend systems — including data sync pipelines, search APIs, email/SMS delivery, and workflow automation — with a focus on data integrity, consistency, and customer-facing reliability.
Drive platform-level projects that unlock new product capabilities: rate limiting, tenant isolation, and scaling our databases and indexing infrastructure as customer data volumes grow.
Participate in the shared platform on-call rotation and lead post-incident reviews, improving system observability and resilience over time.
Help shape the backend foundation for Rally’s agentic platform — ensuring our core systems can support AI agents running research workflows at scale.
Influence architectural decisions and establish engineering standards across the backend stack.
What you'll bring
6+ years building and operating complex backend systems in production, ideally at a startup or high-ownership environment.
Excellent communication skills and a collaborative mindset — excited to partner with product, design, and go-to-market teams, in addition to your fellow engineers.
Deep experience with distributed systems correctness: consistency models, idempotency, CDC pipelines, and fail-closed design in systems.
Qualification

Preferred
Experience as an early or founding member of a platform team — building standards and norms from scratch.
Familiarity with GraphQL APIs and the Prisma ORM.
TypeScript/Node.js experience. Our codebase is fully TypeScript, but fluency in reading and reviewing it matters more than writing it from scratch.
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.
