Principal Cloud Software Engineer

As a Principal Cloud Software Engineer at ManTech, your responsibilities include designing, developing, and maintaining backend applications for the ServiceNow platform primarily using Java. You will also ship and run services in cloud environments with a strong focus on AWS, troubleshoot issues by analyzing data and code, and provide operational support for custom developments and third-party integrations. Additionally, you will engage in unit-testing and resolution of any code defects, as well as assist in technical design documentation.

To qualify for the Principal Cloud Software Engineer role at ManTech, you should have a Bachelor’s degree or 4+ years of additional software development experience in lieu of a degree. A minimum of 7 years in software development is essential, along with proficiency in backend Java development. Experience with at least one scripting language, solid foundational knowledge of Linux operating systems, and holding a current DoD Approved 8570 IAT Level II Certification are also part of the qualifications for this position.

A Principal Cloud Software Engineer at ManTech should have a strong command of Java for backend development. In addition to Java, familiarity with at least one scripting language such as Ruby, Python, Perl, Bash, or JavaScript will be beneficial. Knowledge of infrastructure as code (IaC) tools like Terraform and CloudFormation, along with container orchestration tools such as Kubernetes or ECS, is preferred.

The TS/SCI w/Polygraph clearance is crucial for the Principal Cloud Software Engineer position at ManTech due to the sensitive nature of the projects involved. This security clearance ensures that all engineers can access classified information and work on projects that directly support national security, making it an essential requirement for this role.

The work environment for a Principal Cloud Software Engineer at ManTech is collaborative and dynamic. You will spend around 50% of your time stationary, often working on projects in an office setting, but you'll also be required to interact with co-workers, management, and customers. This interaction may occur through meetings, emails, or virtual communications, where you might even deliver presentations on your innovative ideas and solutions.

When discussing your experience with backend development in Java, focus on specific projects you’ve worked on, the frameworks you utilized, and how you ensured code quality through testing. Highlight your ability to design efficient applications and your method for troubleshooting any issues that arose during development.

In responding to this question, emphasize a systematic approach to troubleshooting. Outline the steps you take when an issue arises, such as gathering data logs, replicating the problem, and evaluating system performance. Mention any tools or techniques that you've found particularly effective in identifying and resolving issues quickly.

Share specific resources you use to stay updated on cloud technologies, such as tech blogs, online courses, webinars, or community forums. Emphasize your commitment to continuous learning and how this helps you implement the latest solutions effectively in your projects.

Describe IaC as the management of infrastructure through code, which allows for automation and consistency across deployments. Discuss your experience with tools like Terraform or CloudFormation, and provide examples of environments you have built or maintained using IaC principles, touching on the benefits such as reduced errors and faster deployments.

Illustrate your understanding of microservices as an architectural style where applications are composed of small, independent services that communicate via APIs. Talk about your experience designing or working with microservices, the challenges you faced, and how this architecture improved the scalability and maintainability of applications.

Explain your approach to unit testing, including the frameworks you use, how to ensure coverage, and your methodology for writing effective test cases. Share a scenario where unit testing helped you identify a critical bug before deployment and the overall impact on software quality.

Discuss your familiarity with container orchestration tools like Kubernetes or Amazon ECS. Share specific examples where you've successfully deployed, scaled, and managed containerized applications, and highlight how these tools have enhanced your team’s efficiency and deployment consistency.

Emphasize the importance of security throughout the software development lifecycle. Discuss how you implement security best practices, conduct regular assessments, and stay informed about vulnerabilities, especially in cloud applications where security risks can be significant.

Share how you assess project timelines, resources, and impact to prioritize effectively. Talk about time management techniques and tools you utilize, such as Agile methodologies or project management software, to juggle multiple tasks while ensuring stakeholder satisfaction and meeting deadlines.

Highlight your experience with ServiceNow by detailing your involvement in developing, integrating, or configuring applications on the platform. Emphasize the impact of your work on operational efficiency and how you have tailored ServiceNow solutions to meet specific client requirements.
