Job Description:

Leidos is looking to improve and advance our organization. Our program is focused on the delivery of data center services to our CMS customers and is structured around both current and legacy platforms in a consumption-based services model. We are looking to add skilled, energetic leaders and technologists who believe in cross functional teams, exhibit broad-based skills, maintain a customer-focused mindset, and have a willingness to step out of their work stream to complete the job.

With a "no downtime, zero outages" vision and mantra, we support a range of data center needs ranging from self-service to white-glove services, all of which are based on our customer's required level of support. Our organization is comprised of teams supporting PMO, Security, Quality, Intake, Service Delivery, Engineering, and Service Operations. With these teams, there is access to resources from our functional teams supporting Network, Security, Firewall, z/OS and z/VM operations, Unix Operations, Change Management, Monitoring, Capacity Management, x86 Operations, and Storage Operations. Part of everyone's responsibility is to help drive the new consumption-based services oriented model.

Now to you - your mission, if you choose to accept it as a Sr. PaaS Was Engineer is to be able to integrate into our team and automate processes such as COTS (Commercial Off-The-Shelf) product installation, configuration, and patching. The engineer must also be able to troubleshoot application run-time issues, resolve those issues, and provide advice regarding changes necessary for the architecture of the application or the application code to prevent such issues from recurring. A quick learner is needed to configure new web applications and also to modernize the current applications with new COTS products.
