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.

Software design & development: Translate product visions or operational needs into robust software architectures, implementing them across our stack to ensure an exceptional user experience.
Technical exploration & problem-solving: Dive into challenging technical problems, often involving new and undefined areas, using innovative approaches to develop practical solutions.
Deployment & impact monitoring: Take projects from development to deployment, collaborating with Product and Data teams to monitor their impact.
Technical leadership: Mentor junior engineers, review technical specs and code, and steer technical discussions.
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.
