Internal Application: Senior DevOps Engineer

About Us:

ACME Technologies is both a payment infrastructure provider and a cloud application provider. Our core ticketing and membership applications are powered by ACME Pay, our payment infrastructure that can be used by any SaaS company seeking to monetize payments.

Our cloud application stack is composed of eCommerce (B2C) and web-based Backoffice (B2B) applications as well as Point of Sale and Access Control applications for in-venue sales and scanning.

Our payment infrastructure stack is a modern API layer with SDKs, providing a rich omnichannel (online and POS) interface at the payment acceptance layer all the way to back office management and daily payout to sellers, with a global footprint. See acmepayments.com.

Our back-end infrastructure is modern, elastic, and based on the latest Java microservices architectures and modern REST API principles. The challenges are great to keep our infrastructure reliable and secure, with high uptime and high performance as we process the main integrated payment use cases for our app layer and external API clients. If you like great engineering challenges, it’s hard to find better; we do deep technology.

Our culture is a collaborative, flat hierarchy. Given we build mission-critical systems, we take pride in being a low-key, solution-oriented company that deals with problems productively and collaboratively. Everybody is part of the solution. As a core deep tech company, we focus on great engineering to support our clients and sales.
