Apply for this job
adjoe is a leading mobile ad platform developing cutting-edge advertising and monetization solutions that take its app partners’ business to the next level. Part of the applike group ecosystem, adjoe is home to an advanced tech stack, powerful financial backing from Bertelsmann, and a highly motivated workforce to be reckoned with.  We are looking for a Senior DevOps engineer to strengthen the Cloud Engineering team.

Meet Your Team: Cloud Engineering

The Cloud Engineering team is the core of adjoe’s tech department. It is responsible for the underlying infrastructure that helps adjoe’s developers to run their software – and the company to grow its business. 

From various AWS services to Kubernetes and Apache foundation open source projects, the team continuously validates new cloud and architecture services to efficiently handle a huge amount of data. Cloud Engineering tackles the challenge of choosing when to use self-managed or managed services to reduce $300K of monthly hosting costs, while still ensuring convenience and data security for adjoe’s developers. 

Because adjoe needs to ensure high-quality service and minimal downtime to grow its business, Cloud Engineering invests heavily in monitoring and alerting technologies for insights into system health (networking, application logs, cloud service information, hardware, etc.). The cloud engineers also provide working solutions, knowledge, and documentation to the entire community of adjoe developers, giving them the autonomy to work on the infrastructure themselves and ensure the smooth sailing of adjoe’s systems.
