Senior Platform Engineer

Senior Platform Engineer

As a Senior Platform Engineer, you'll own and scale the backend systems and data infrastructure that power Rally's core product — enabling our platform to handle hundreds of millions of participant records, billions of events, and the next generation of AI-native research workflows.

Your work will directly determine how fast Rally's product can move. You'll strengthen the systems that every product engineer builds on and ensure our platform can support the ambitious roadmap ahead.

You'll join our Platform Engineering team — a small, high-ownership group responsible for the reliability, scalability, and developer experience of Rally's core backend.

Work style: Remote-first within the United States, with regular async collaboration and optional in-person team onsites.

Rally is the User Research CRM that helps product, design, and research teams talk to their users quickly, safely, and at scale. Our platform automates the unglamorous parts of research—participant recruitment, outreach, screening, scheduling, consent, and incentives—so teams can spend more time learning from customers and less time wrestling with manual workflows.

We're now building Rally's next chapter: an AI-native platform that handles the full research recruiting lifecycle, end to end.

Trusted by teams at Google, Adobe, Figma, GitLab, Webflow, and others. Backed by Y Combinator, Stage 2 Capital, and Canapi Ventures.

Rally Engineering is a highly collaborative, user-obsessed group focused on making research smoother for both our customers and their participants.

• We work closely with UX Researchers, Research Ops leaders, designers, and product managers at some of the world's most user-centric companies.
• We use Rally to build Rally — talking to our own users frequently, running studies on our platform, and feeding insights straight into the roadmap.
• We favor small, empowered teams, high ownership, and a tight feedback loop between customers, product, and engineering.

Rally is in the middle of a massive shift in how companies run user research: from ad-hoc, one-off projects to continuous learning that informs every product decision. In this role, you'll help define what that future looks like — for Rally as a product and for the teams who rely on us to run research at scale. You'll join at a stage where we have strong product-market fit, a fast-growing customer base, and plenty of hard, interesting problems left to solve.

Rally's platform team owns the critical systems that power everything from participant outreach and scheduling to AI-driven research workflows. As we scale and build out our agentic platform, we need a strong backend generalist who can take ownership of high-impact systems and help the team move faster and with more confidence.

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 reliability and operational excellence.
• Drive platform-level projects that unlock new product capabilities: activity feeds, custom objects, rate limiting, tenant isolation, and data enrichment integrations.
• Collaborate closely with product engineers to identify and eliminate platform bottlenecks, improving the velocity and reliability of feature development across the team.
• 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.
• Mentor engineers through code reviews, technical design discussions, and day-to-day pairing as the team grows.

What you'll bring:

• 6+ years of experience building and operating complex backend systems in production, ideally at a startup or high-ownership environment.
• Strong TypeScript/Node.js fundamentals with hands-on experience in a fully TypeScript codebase.
• Deep experience with AWS managed services (ECS/Fargate, RDS/Aurora, MSK) and modern cloud-native architecture patterns.
• Experience with event-driven systems and streaming infrastructure (Kafka or equivalent).
• Proven track record of owning significant technical areas end-to-end — from design through implementation, rollout, and ongoing operation.
• Strong understanding of observability (metrics, logs, traces) and comfort with on-call responsibilities and production incident response.
• Excellent communication skills and a collaborative mindset — excited to partner with product, design, and go-to-market teams, not just other engineers.

Nice to have:

• Familiarity with workflow orchestration systems (e.g., Temporal) or distributed systems patterns.
• Experience with Elasticsearch or similar search infrastructure at scale.
• Exposure to AI-native product development or agentic workflow patterns.
• 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.
