This includes automation of kit infrastructure, configuration, and application deployment across diverse environments.
- Design and develop custom Ansible modules and plugins in Python, applying sound software engineering practices such as modular design, error handling, and documentation.
- Collaborate with software development teams across the company to create highly parameterized Ansible that aligns the software product stack, transforming project requirements into robust automation solutions.
- Configure and automate physical hardware and network appliances, such as servers, switches, routers, and firewalls, using Ansible.
- Implement security controls, including STIG hardening and SELinux, within the automation pipeline to ensure “secure by default” deployments.
- Build and maintain CI/CD GitHub Actions pipelines that perform extensive automated linting, unit, and integration testing of automation code.
- Establish coding standards, code review practices, and testing strategies for the automation codebase, and mentor other engineers.
- Collaborate with stakeholders to ensure technology standards, security controls, and engineering practices are well understood and consistently applied.
- Partner with internal teams to deliver technical demonstrations and showcase SealingTech capabilities to customers.
- Identify and define high-level functional and technical requirements by working with the user community and leveraging knowledge of existing DoD enterprise architectures.
