1. Tech: Collaborate with the Product team to innovate on Joko’s user-facing products and shape the future of the online shopping experience, taking full ownership from conception to deployment.

• Strategic collaboration: Work closely with the Product and Operations teams to align technical projects with company goals.

• Process & tool enhancement: Continuously evaluate and improve team processes and tools to ensure maximum efficiency and effectiveness.
