Staff Backend Engineer, Commerce

Zapier's mission is to make automation work for everyone. The Commerce Zone builds and operates the infrastructure behind billing, subscriptions, payments, pricing, entitlements, and checkout across all Zapier offerings. As a Staff Engineer, you will own the technical vision and long-term architecture for the Commerce Zone, defining pricing primitives, service boundaries, and data models to enable rapid pricing and packaging changes while ensuring financial accuracy.

• Serve as a technical leader within the Commerce Zone, partnering with Engineering, Product, and Design to shape strategy and roadmap.
• Shape the long-term platform vision, balancing near-term delivery with durability and operational excellence.
• Lead high-impact technical initiatives, decoupling billing from account systems, clarifying boundaries, and consolidating pricing infrastructure.
• Own revenue-critical systems (Billing, Pricing, Payments, Checkout, Entitlements) ensuring resilience, observability, and correctness.
• Guide API design, data modeling, caching strategies, and system architecture.
• Collaborate with Pricing & Packaging, Product, Design, Support, and Operations to drive ARR growth and customer experience.
• Drive measurable improvements in latency, reliability, conversion, and retention.
• Mentor engineers, conduct code reviews, and champion documentation and developer experience.

• Proven engineering impact in complex production systems at scale; many strong candidates have 8+ years of experience, but hiring is based on impact and capability.
• Strong domain knowledge in billing, subscription management, payment processing, or financial platforms, including metered billing, pricing models, entitlements, and revenue recognition.
• Experience designing and building APIs for multiple consumers, with a track record of resolving performance bottlenecks through profiling, caching, and database optimization.
• Outcome-driven and customer-focused, with cross-team leadership and proactive ownership.
• AI fluency: regular use of AI coding tools and judgment on where they accelerate delivery.
• Comfort with large, mature codebases and navigating a monolith.
