Mid Level Mastercard Software Engineer Jobs in Chicago, IL

Gigantic Playground is hiring a Lead Full-Stack Software Engineer & Architect to own technical direction across multiple client engagements. This role requires prior software agency experience and comfort operating in a fast-moving, multi-client environment. You will define architecture, lead engineers, and partner directly with clients to deliver complex, production-grade systems.

This is a fully remote role with occasional travel for client engagements, on-site installations, or internal planning. Candidates based in San Diego may work from our headquarters but are not required to do so.

The Gigantic Playground team specializes in envisioning and implementing innovative ways for end-users to interact with technology, often in ways that may not resemble traditional technology. The team oversees the entire process, from ideation and architecture to the development and installation of Gigantic Playground experiences, in partnership with our clients.
