  • Manage end-to-end integration testing, including SIT and UAT support.
  • Develop and maintain technical documentation, architecture diagrams and operational procedures.

  • Experience with system integration in co-location and cross-country rollouts for a real-time, low-latency application.
  • Strong communication skills.
  • Able to work independently.

  • Integration and middleware: JBoss, WebSphere, REST and SOAP APIs, XML and JSON, IBM MQ message queues, SFTP, SSH and Connect:Direct.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
