Senior Back-end Engineer

#LI-DNI

Develop the backend systems that keep our platform running smoothly and smartly

At Gomibo, we build almost all of our backend systems ourselves—from payments and logistics to order processing and content management. Our backend teams design and maintain the core systems that keep the platform running smoothly. As a Senior Backend Engineer, you'll lead complex projects, make key architectural decisions, and help your team deliver reliable systems that make a real impact.

This is a hands-on engineering role. You'll write code, make architectural choices, and work closely with product managers, designers, and fellow engineers to design backend solutions that stand the test of scale and complexity. You'll think in systems, not just features—spotting architectural bottlenecks, identifying cross-team dependencies, and designing solutions that scale smoothly as we grow.
