Senior Software Engineer, Back-End (San Francisco)

Senior Software Engineer, Backend

What happens when your business model breaks the assumptions most e-commerce platforms were built on?

You build your own.

At Short Story, we’re rethinking how online shopping works: from inventory and logistics to personalization and fit, because the standard playbook doesn’t work for our customers. That means building systems that don’t fit neatly into existing patterns.

If you’re excited by designing systems from first principles and working on problems without obvious answers, you’ll feel at home here.

The Role

As a Senior Backend Engineer, you’ll design and build the services that power our core workflows, from order processing to logistics and internal operations.

You’ll own meaningful parts of the system end-to-end, making decisions about data models, APIs, and system behavior. You’ll work closely with product, frontend, and operations to ensure what we build is reliable, scalable, and actually solves the problem.

• Design, build, and maintain backend services that power core business workflows
• Own projects end-to-end, from early design through production and iteration
• Design APIs and data models that are clear, stable, and easy to work with
• Work across systems (orders, inventory, logistics, data) to solve complex, interconnected problems
