Full Stack Software Developer

Build the workflow engine and product surfaces finance teams rely on every day.

@loopfour is building workflow automation for finance operations.

Our software takes the manual, repetitive work off finance teams so they can focus on the decisions that matter.

Finance teams spend their days moving documents between tools, chasing approvals, and reconciling numbers that already exist somewhere. Founders, controllers, and CFOs are drowning in work that software should have handled hours ago.

We are not building another dashboard. We are building automation that fits how a business actually operates, in the tools teams already use, with a full audit trail behind every action. AI for finance, without the black box.

The kind of person who thrives here

YYou don't need to check every box.

If you're smart, driven, and excited about building something important, and you want to be part of a small team that moves fast and cares about doing things the right way, we want to hear from you.

You'll work closely with the team and founders, with a lot of trust, autonomy, and support.

We don't do long, drawn-out interview loops. We keep it simple and respect your time.

You'll start with a Zoom conversation with the founders and team to see if there's a fit.

If there's mutual interest, we'll ask you to show us something you're genuinely excited about. Anything works:

• A side project
• An experiment or prototype
• A tool you've built and love
• A walkthrough of your GitHub and the work you're most proud of

We move fast, communicate clearly, and make decisions quickly, without unnecessary steps.

We're especially excited to work with engineers based in the Bay Area. Build from anywhere, but if you're nearby, even better. You'll work with a tight, founder-led team. We will sponsor visas.
