About the role

Key responsibilities & impact

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.

Requirements

What you’ll need

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.
