Pros
Getting paid is nice. The backend codebase is in Elixir. There are a few good engineering managers on the OMS team. Most people are good humans.
Cons
The software is brittle. Their customers needed a few simple CRUD application, which could be maintained by a handful of good engineers. Unfortunately, they raised a lot of money during the pandemic when VCs were sweet on supply chain startups. They used the money to hire a lot engineers and built a faulty and Byzantine micro services system. Several of the engineers they hired were very good and/or well-respected in the Elixir community. Almost all of those people left the company because upper management didn't heed their warnings that recklessly adding questionable features on top of a bad foundation was a recipe for disaster. Most of the remaining engineers will implement whatever new features the leaders dream up to land a customer, but in doing so they often break existing behavior and make the system harder to maintain. Management has begun firing anyone who raises concerns about architectural decisions or expresses doubt about the long-term viability of the software. Working the support engineering shift here will make you feel terrible. One of the high ranking engineers has a toxic reputation in the Elixir community. You may have to work closely with this person.
