Senior DevOps Engineer

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


Our back end infrastructure is modern, elastic and based on the latest Java micro services architectures and modern REST API principles. The challenges are great to keep our infrastructure reliable, 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 collaborative and quite flat in terms of hierarchies. Given we build mission critical systems, we take pride in a low key, solution oriented company that deals with problems productively. Everybody is part of the solution. As a core tech company, we focus on great engineering to support our clients and sales.
