Back-end Software Engineer II
#LI-DNI
Build scalable systems that power our platform across Europe
At Gomibo, we build nearly everything in-house—from payments and logistics to repair workflows and customer communication. As a Medior Backend Engineer (Software Engineer II), you'll work on the backbone of these systems. You'll take ownership of backend features and improvements, solve real-world performance issues, and help shape how we build reliable services. Think 555 phones × 473 contracts × 65 bundles — there's a lot of logic behind the scenes to keep everything working smoothly.
You'll work closely with frontend engineers, product managers, and occasionally a product designer. You're trusted to make technical decisions within your scope, write clean and maintainable code, and contribute to the team's planning and direction.
