• Deliver seamless, bi‑directional data synchronization across marketplace, e‑commerce, ERP, and other enterprise systems, ensuring accuracy, consistency, and low‑latency data flow.
• Partner closely with cross‑functional stakeholders—including Product, Inventory, Operations, and external partners—to understand business needs, translate them into technical requirements, and drive aligned outcomes.
• Architect and evolve enterprise‑grade systems that remain intuitive for developers, easy to iterate on, and capable of supporting rapid product growth.
• Contribute to and accelerate the broader Inventory team roadmap, providing technical insight, proactive problem‑solving, and hands‑on implementation support.
