What you will do
- Own one or more production services end-to-end in the commerce stack (merchant portal, partner integrations, marketplace platform, billing engine, fulfillment apps, or support tooling), including design, implementation, rollout, and ongoing operations.
- Deliver measurable improvements, such as reducing merchant onboarding time by 50% within 6 months for assigned flows, bringing reconciliation variance below 0.1% month-over-month for owned payment paths, and reducing incident-driven customer-impacting downtime to under 30 minutes MTTR for priority services.
- Lead cross-functional launches by defining success criteria, authoring rollout and rollback plans, coordinating with Field Operations, Safety/Compliance, Product, and Finance, and owning post-launch remediation and success metrics.
- Build and enforce marketplace controls and policy tooling that enable operators to safely manage pricing, capacity allocation, and prioritization, including feature gates, experiment scaffolding, and pre-production simulation using historical mission data.
