Software Engineer 3 with Security Clearance

If you want to be part of a dynamic team delivering cutting-edge cyber training solutions, this is the place for you. Amentum is seeking a Software Engineer to join the DevOps team in Hanover, MD. The team develops, deploys, and supports mission-focused cyber training solutions used across multiple locations. Team members work in a collaborative, multidisciplinary environment supporting the entire software development lifecycle, including requirements analysis, software development, testing, deployment, infrastructure management, and operational support.

Engineers work closely with instructors, developers, and system administrators to deliver reliable, realistic training capabilities. Unlike many software organizations where engineers are assigned to a single product or technology stack, members of the DevOps team contribute across a diverse portfolio of applications, services, and supporting infrastructure. This provides opportunities to build broad technical expertise while collaborating with teammates to deliver integrated solutions throughout the software development lifecycle.

This position is ideal for software engineers who enjoy solving complex technical challenges, learning new technologies, and applying their skills across a diverse portfolio of software, infrastructure, and operational systems.

Work Schedule: The courses supported by this team operate from 0700-1800 Monday through Friday. Contract core hours are 1000-1400. The DevOps team maintains flexible schedules; however, occasional support outside normal hours may be required for testing, maintenance, and operational activities.

Essential Responsibilities: The Software Engineer contributes to the design, development, deployment, and maintenance of software applications and supporting infrastructure. Software Engineer 3 personnel apply technical expertise and institutional knowledge to guide implementation decisions, mentor engineers, and improve the team's applications and operational environment. Team members are expected to develop expertise across multiple areas of the software development lifecycle while contributing their strengths in specific technical domains. Responsibilities include:

• Analyze complex mission requirements and evaluate the impact of proposed changes across applications, services, deployment pipelines, and operational environments to recommend and implement software solutions that balance mission needs, reliability, and long-term maintainability.
• Review software designs, architecture, and code to ensure maintainability, scalability, and adherence to engineering best practices.
• Design, develop, deploy, and maintain user interfaces, backend services, APIs, databases, automation tools, and supporting infrastructure.
• Design, implement, maintain, and continuously improve software development and deployment pipelines.
• Provide technical leadership for the creation, maintenance, troubleshooting, and continuous improvement of realistic cyber training environments and the software and infrastructure that support them.
• Perform software testing, debugging, validation, and analysis of results.
• Evaluate emerging technologies, development methodologies, and engineering practices, recommending adoption where they provide measurable benefit to the team or mission.
• Collaborate with instructors, developers, system administrators, and other stakeholders to document solutions, improve workflows, and enhance training capabilities.
• Share technical knowledge through collaboration, design discussions, code reviews, and mentoring of less experienced engineers. Work Environment, Physical Demands, and Mental Demands: The DevOps team works in a SCIF air-gapped environment at a contractor site.

Minimum Education & Years of Experience: A master's degree in a Computer Science, Software Engineering, Information Systems or related field and five (5) years of relevant experience OR Bachelor's degree in the same fields and (10) years of relevant experience OR Associates degree (or 18 semester hours of military coursework/training in a computer related field) and twelve (12) years of relevant experience; OR High school diploma/GED and fourteen (14) years of relevant experience. Relevant experience includes technical leadership, software architectures/design, complex trouble shooting, and supporting controlled releases, operations for enterprise systems.

Security Clearance Required: TS/SCI with Poly Minimum Requirements (Knowledge, Skills, and Abilities): LCAT Domain Specialized Requirements

• Technical Leadership: Experience leading design/code reviews, mentoring engineers, and setting implementation standards
• Architecture & Integration: Experience designing service interfaces/APIs, integrations, and data models for enterprise systems
• DevSecOps Practices: Experience applying secure coding practices, dependency/vulnerability remediation, and CI/CD-driven delivery in controlled environments
• Databases: Experience with relational databases and SQL performance considerations
• Platforms: Experience supporting applications in Linux and Windows environments

Preferred Qualifications: The ideal candidate has experience contributing to software development, DevOps, or application support activities and a desire to expand their knowledge across the software development lifecycle. Team members may initially bring deeper experience in areas such as user interfaces, backend services, infrastructure, automation, or deployment. These areas represent technical strengths rather than separate roles. Engineers are expected to expand their skills across the full software development and deployment lifecycle. Role Expectations

• Serve as a technical resource for software development, deployment, and operational support activities.
• Apply engineering judgment and institutional knowledge when evaluating implementation approaches and resolving complex technical issues.
• Provide technical ownership for assigned applications, services, and infrastructure throughout their lifecycle.
• Mentor and support less experienced engineers through collaboration, technical guidance, and code reviews.
• Continuously broaden expertise across the team's applications, services, deployment pipelines, and supporting infrastructure. Preferred experience includes one or more of the following:
• Full-stack software development using modern frontend and backend technologies.
• Database design and development using SQL and NoSQL technologies.
• Software testing, source control, and CI/CD practices.
• Linux and Windows system administration, virtualization, containers, and application deployment.
• Automation, scripting, and DevOps tooling.
• System integration, networking, and application configuration. Successful team members will:
• Demonstrate broad technical expertise while continuing to expand knowledge across the team's portfolio.
• Apply sound engineering judgment when balancing mission needs, technical debt, maintainability, and operational risk.
• Collaborate effectively across technical disciplines to deliver integrated solutions.
• Communicate complex technical concepts clearly through documentation, design discussions, and collaboration.
• Lead by example through high-quality engineering practices, technical mentorship, and continuous improvement.
