Fishtail · Sr. Full Stack (rails/hotwire) Engineer

About Fishtail:

We are a super un-sexy, VC-backed, revenue-generating, remote-first, Trade Finance automation company (think Pipe for the physical world) that's bringing the the $10tn Trade Finance space in to the 21st century.

Problem area:

When Walmart gives La Croix a $100k order for seltzer, not only does Walmart not pay after receiving goods for 3-4 months but La Croix has to cover the cost of actually making their goods for a bunch of time (months). As a small business, this sucks hard.

Fishtail will lend to La Croix when they get an order from Walmart so they can satisfy demand without tying up huge amounts of working capital. Usually banks will lend to folks only when the product makes it to Walmart (and only to large companies, who don't traditionally need $) -- the net effect of Fishtail is that we lend earlier in the chain to smaller businesses (which is a super hard problem).

About the position:

We’re looking for an experienced full-stack engineer with in-depth experience in Ruby on Rails who will join our team of exceptional developers (scattered around the world) working in a fast-paced, mostly-async environment to deliver world-class software.
