Description:

Senior Linux Infrastructure & Automation Engineer

Whitehall Resources are looking for a Senior Linux Infrastructure & Automation Engineer. This role is mainly remote working, with some travel to Hertfordshire, for an initial 3-month contract.

***Inside IR35***

Job Description:
Project context:
Our exploration rover breadboarding and telecoms satellite infrastructure is using increasingly IM unsupported tools and services (be that older systems, newer systems, OS/software that IT simply don't support etc.) raising a need to manage more and more of this internal to the site/project/department where we either want to be on more recent tooling (breadboarding) or maintain older tooling for spacecraft projects whose lifespan is in the tens of years and is expected to remain fixed.

The role is to support this infrastructure in both the GNC and software teams as the projects require, this will involve responsibility for maintaining/extending but may in the case of older systems require learning/understanding the current infrastructure before making substantial adjustments/redeployments.

Our current implementation on breadboarding relies on Ansible executing against a variety of different hosts performing operations from install/update/upgrade packages thru host environment configuration thru checkout and build internal projects from source for deployment on host or in containers.

Expect to be working with a range of hosts on breadboarding (industrial PCs, workstation PCs, VMs) that need as much commonality but each have their own quirks (i.e. not all the industrial PCs can be expected to have consistent network access and will travel out into the field with the rover). The telecoms side is far more consistent with tens of VMs that need to and can be maintained as identical environments.

Required Knowledge:
* RedHat Ansible as mandatory skill
* Git for version control of scripts
* Ansible for configuration control
* Autoinstall or similar for system deployment
* Ubuntu 20+ or similar Debian derivatives as OS
* Podman or similar containerisation
o w/ hardware passthrough for graphical applications on unsupported hardware/software (i.e. Nvidia K2000 on RHEL 6 and co)
o w/ hardware emulation i.e. QEMU
o Used for development and for service hosting
* Configuration/installation of physical machines and the required support hardware (racking machines, spec racks w/ acoustic dampening, spec power delivery/UPS, spec network requirements, etc)
* Architecture design and implementation of an IT system.
