Senior Service Engineer - CTJ - Top Secret

Responds to incidents during regular on-call rotations by identifying the level of impact, troubleshooting issues, and deploying appropriate fixes to resolve root cause(s). Alerts product teams and owners to major customer impacting issues and escalates resolution of complex and highly impactful issues affecting multiple components or features to other engineers or engineering teams as needed. Shares details related to incidents and their resolution through postmortem reports and during regular review meetings. Demonstrates understanding of service and/or system design, interactions between technology layers and components, functions of physical infrastructure (networking and servers) and cloud-based infrastructure, and dependencies at scale. Contributes to improving service architecture and design of a hybrid (physical and cloud-based) service through automation, software development, and networking with minimal guidance. Adjusts configurations and defines infrastructures to improve the availability, reliability, efficiency, observability, and/or performance of supported products and services, with minimal guidance from other engineers. Designs, implements, and maintains Infrastructure as Code (IaC) solutions to provision and manage hybrid cloud and on premises infrastructure in a repeatable, secure, and auditable manner, minimizing configuration drift and manual intervention. Authors, reviews, and maintains IaC templates and modules to deploy networking, compute, storage, identity, security controls, and PKI-related infrastructure across isolated and regulated environments, following least privilege and defense in depth principles. Stays current in knowledge and expertise as technology landscape evolves specifically as that technology relates to Cloud networking, physical networking, automation, and Linux (Debian and Red Hat based distributions). Contributes to the adoption of new solutions. Proactively seeks opportunities to learn and receive feedback. Shares insights and best practices that can be applied to improve development and operations of the system, platform, or product components and features by participating in design reviews, incident drills and debriefs, and regular meetings, as well as interactions with more experienced Service Engineers and members of product engineering teams. Bachelor's Degree in Computer Science, Information Technology, Mechanical Engineering, Electrical Engineering, Aerospace Engineering, Data Science, Cybersecurity, or related field AND 3+ years technical experience in software engineering, network engineering, service engineering, systems engineering, or industrial controls OR equivalent experience. These requirements include, but are not limited to the following specialized security screenings: Candidates must have an active TS and be willing and eligible to upgrade to TS/SCI (with polygraph) or have an active TS/SCI and be willing and eligible to upgrade to TS/SCI (with polygraph). This role will require candidates to maintain the TS/SCI (with polygraph) clearance. Failure to maintain or obtain the appropriate clearance and/or customer screening requirements may result in employment action up to and including termination. Clearance Verification: This position requires successful verification of the stated security clearance to meet federal government customer requirements. You will be asked to provide clearance verification information prior to an offer of employment. Citizenship & Citizenship Verification: This position requires verification of U.S. citizenship due to citizenship-based legal restrictions. Specifically, this position supports United States federal, state, and/or local United States government agency customer and is subject to certain citizenship-based restrictions where required or permitted by applicable law. To meet this legal requirement, citizenship will be verified via a valid passport, or other approved documents, or verified US government Clearance Proven experience in scripting languages such as Linux Bash, Windows PowerShell, and Python. Experience with Linux operating system distributions, including Debian, Ubuntu, Red Hat, and Azure Linux. Experience working with common automation technologies such as Ansible. Hands-on experience building and operating Infrastructure as Code (IaC) solutions using tools such as ARM/Bicep or equivalent declarative or programmatic provisioning frameworks. Experience developing reusable IaC modules and managing versioned infrastructure definitions across multiple environments (e.g., development, test, production, and isolated enclaves). Familiarity integrating IaC into CI/CD systems for automated infrastructure deployment, drift detection, and compliance validation. Experience managing infrastructure state, secrets, and credentials securely within IaC workflows. Understanding of applying IaC to hybrid and isolated environments, including networking, PKI, security appliances, Linux-based systems, and cloud infrastructure. Ability to review, troubleshoot, and refactor IaC code for scalability, security, reliability, and long-term maintainability.
