Loop is the essential eCommerce operations platform built to streamline your returns, exchanges, tracking, order editing, checkout experiences, and more. Backed by CRV.
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.
What they're looking for
- 5+ years building web applications, backend services, and APIs. Strong PHP/Laravel experience preferred
- You have a point of view on where AI helps and where it gets engineers into trouble, and you actively help your team navigate that line
- You track how your code behaves in production, not because someone asks you to, but because you own the outcome. You've caught regressions before support tickets did
- You can evaluate architectural trade-offs and make defensible decisions, not just implement what you're handed
- You have examples of leading technical initiatives, mentoring engineers, and driving cross-functional alignment
- You operate with intensity and hold a high bar for your own work and for the people around you. You give direct feedback, ask for help early, and respond to setbacks with ownership rather than withdrawal

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. The role has shifted: you are not primarily a writer of code. You are the judgment layer, the person who determines what should be built, validates that what was built is correct, and owns the outcome in production. At the senior level, that judgment extends beyond your own work to the systems, standards, and people around you. You're not just using AI well — you're helping your team develop the habits and instincts to use it well too.
We work from our HQ in Columbus, OH, and are distributed throughout the United States, select Canadian provinces, United Kingdom, and Australia. For this position, we're open to Columbus, OH; Boston, MA; Chicago, IL; Austin, TX; Los Angeles, CA; or fully remote.
