Senior Platform Engineer

ROLE AT A GLANCE

What: As a Senior Platform Engineer, you'll own the backend systems that make Rally's control plane trustworthy — governance, permissions, consent, and audit — so that every agent, MCP call, and API request follows the customer's rules, every time.

Impact: Rally's biggest customers trust us to decide who can be contacted and under what conditions. Your work will be the reason that trust holds as we scale agent-led research across thousands of product builders.

Team: You'll join Platform Engineering — a small, high-ownership group responsible for the reliability and correctness of Rally's core backend. You'll report to the Head of Engineering and work closely with the Data Integrity, Scheduling, and Agents teams.

Where: Remote-first across the US, with hubs in New York and Boston.

ABOUT RALLY

In a world where anyone can ship anything, the teams building closest to their users win. But talking to users is still much harder than it should be. Pulling lists, chasing consent, juggling calendars, sending incentives: it's why most product teams skip research altogether.

We're here to end manual recruitment.

Rally is agentic research infrastructure: the system that lets companies talk to their own users safely, at any scale. Tell Rally what you want to learn, and Rally Agent builds the study, finds the right participants, and handles outreach, scheduling, and incentives, all within your company's guardrails. It works from the Rally app, from Slack, or from the AI tools you already use. Agents handle the busywork, so people focus on the human parts: learning from each other.

Today, teams at Google, Meta, Figma, Ramp, Perplexity, and MongoDB run their research on Rally. And we're building a company that lasts, investing in the product and the team for the long haul.

THE OPPORTUNITY

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.

WHAT YOU'LL DO

- 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 stan
