We are looking for a Linux Systems Engineer in a DevOps role to join an experienced team of experienced DevOps engineers. This team is conducting DevOps and Systems Admin and working directly with software development teams. No general business / user contact.

Your new role will be responsible for supporting existing systems and designing and implementing technical solutions for supporting the existing infrastructure with a mixture of on premise systems.

AWS skills are not a must have but Linux skills are.

The team regularly adopt new and better technology; however, the team's tech stack currently consists of:

* Operating Platforms - We are more biased towards Linux which we are currently migrating fully to, so you must have Linux knowledge but we have a mixed Windows and Linux environment at the moment and some training can be given on Windows.

* Cloud: AWS - EC2/ ECS, S3, AWS Inspector, Cloudwatch, SNS, Security etc

* Scripting Languages - Bash (must have), CI / CD - Git, Ansible, Terraform.

* Other skills - XenServer, VMWare, ElasticSearch, Redis, Jenkins, Docker, Nagios, Ganglia, some SQL, PXE Boot installs, kickstart.

* Nice to have: HPC skills in IBM Spectrum Symphony or other HPC systems.

We are looking for a mix of experience, you don't need to have everything, but you will need experience in several areas:

* Technical infrastructure skills across servers, some storage and networks. Currently managing over 250 servers with VMs on XenServer

* Experience with virtualization, Xenserver, Xen, VM Ware

* Some AWS experience, we are currently moving into the cloud

* Experience with programming and scripting in a server environment

* Experience in implementing simple solutions to tricky problems

* Proven working experience in installing, configuring and troubleshooting Linux based environments.

* Understanding of micro service based architectures (Docker)

* Solid experience in system administration and performance tuning of application stacks.

* Some experience with implementing containerised workloads

* Install, configure, test and maintain operating systems, application software and system management tools.

* Networking: Understanding network topologies and common network protocols and services (DNS, HTTP(S), SSH, FTP, SMTP).

* Comfortable with using Linux command line tools for administration tasks

* Good knowledge of security as it relates to cloud-based infrastructure

Skills & experience that would be highly desirable

* Managing large scale tasks from inception to completion

* Linux Server Administration - Redhat, and Centos, some Windows Server Admin is useful but strong Linux skills will grab our attention.

* Bash scripting and Ansible would be desirable

* Automation tooling (Terraform, Ansible)

* Experience with platform monitoring systems, Nagios, Ganglia, ELK.

* Knowledge of networking/connectivity

* Experience using Git in a team environment (merge requests, branching, push, and pulls)
