LEG OpenStack engineer
Experience in configuring and building user space components and server workloads, adding them to the continuous integration system and identifying use cases and test suites to verify the performance and stability. Focusing on OpenStack, look into Tempest failures vs hypervisor support feature set, contribute to Ironic bare metal provisioning.

LEG BigData engineer
Experience in configuring and building user space components and server workloads, adding them to the continuous integration system and identifying use cases and test suites to verify the performance and stability. Focusing on Hadoop and/or Spark, identify a reference real-life representative analytics job, port it to ARM, verify how the performance scales with the number of nodes, profile and identify performance bottlenecks.

LEG DataBase engineer
Experience in configuring and building user space components and server workloads, adding them to the continuous integration system and identifying use cases and test suites to verify the performance and stability. Focusing on MariaDB and/or OceanBase first and then on MongoDB, Couchbase, etc. run representative use cases in a multi-node set up and identify low hanging fruits to improve the performance.

LEG Cloud engineer
Experience in configuring and building user space components and server workloads, adding them to the continuous integration system and identifying use cases and test suites to verify the performance and stability. Focusing on Cloud deployment, set up a scenario with OpenStack provisioning a minimal OS (coreOS or Atomic or Ubuntu core) in conjunction with LXC/Docker and then instantiating a PaaS framework (CloudFoundry, OpenShift Origin or Apache Stratos) for elastically-scaling web apps in Java, PHP, Go, Ruby-on-rails or other runtime languages.

LEG OpenJDK engineer

Good knowledge of code versioning systems, Mercurial is preferred but git is also ok. Expertise in test automation, build systems, performance evaluation. Reference is the openjdk9 porting project to Aarch64: http://openjdk.java.net/projects/aarch64-port/ In cooperation with the rest of the OpenJDK team, the assignee will work in automating test suites, comparing performance numbers across different builds, analyzing Oracle certification test kit (JCK) results and running reference business case Java applications.
