Senior Software Engineer

About this role

About the Role:
Loop is looking for a
Senior Software Engineer
to take meaningful ownership of complex, cross-functional work, from architecture and design through production. You'll build scalable solutions, influence technical direction, and make the engineers around you better.


AI at Loop Engineering:
Engineering at Loop is AI-first, not aspirationally, but operationally. Every engineer is provisioned with Claude Code and Cursor, and we expect AI agents to be your default starting point before you open a file.

• Review AI-generated code with the same rigor you'd apply to any code. Plausible is not the same as correct. At this level, you're also setting the standard for how your team does this.
