Software Engineer
Supports a nationally significant, fast-paced program as part of a high-performing SAFe agile team using DevOps best practices, BDD, and test automation to deliver advanced capabilities for an operational system. Involves full-lifecycle software development—from translating agile stories into design, code, test, and deployment—across server-side logic, web UI, and specialized device programming. Needs strong Java experience, familiarity with multiple languages and tools, and a solid foundation in secure, high-quality software engineering within agile environments.
Requires STEM degree, Security+ certification and 8+ years of experience.
ISSO
Responsible for designing, assessing, and integrating security and Information Assurance (IA) capabilities across complex, multi-enclave systems in support of mission-critical environments. Leads security engineering efforts throughout the system lifecycle, including risk management, security architecture, certification and accreditation, and compliance with NIST RMF, DIACAP, and NSA/CSS processes.
Requires 20+ years of experience, deep expertise in secure system design, threat mitigation, and IA policy, along with DoD 8570 IASAE Level III compliance, and ISSEP and CISSP certifications.
System Engineer
Leads the analysis, design, and integration of complex systems by translating user needs and operational concepts into comprehensive system requirements and architectures. Provides technical leadership across the full system lifecycle, ensuring alignment between requirements, design, implementation, testing, and operational integration. Responsible for maintaining technical integrity, managing risks, and coordinating cross-discipline activities while producing and approving critical systems engineering documentation. Works closely with government stakeholders, program teams, and senior leadership to resolve technical issues and guide decision-making.
Requires extensive experience in systems engineering, architecture frameworks, and lifecycle management for large, mission-critical programs.
System Administrator
Expertise in Red Hat Linux, Windows OS, Active Directory, and VMware patching via Satellite and WSUS. Proficient in file transfers, account management, and scripting, with STE/STN experience considered a plus. Supports programs and contracts of similar scope, type, and complexity. Skilled in delivering reliable system administration and infrastructure support across diverse technical environments.
Requires STEM degree, Security+ certification and 10+ years of experience.
Data Scientist
Leverages two or more skill areas—foundations (mathematical, computational, statistical), data processing (management, curation, visualization, reproducibility), and modeling, inference, and prediction (data modeling and domain-specific assessment)—to extract meaning and value from large datasets. Responsibilities include developing and applying qualitative and quantitative methods, translating analytic questions into technical requirements, and effectively communicating complex findings to both technical and non-technical audiences. Strong background in mathematics, statistics, computer science, or related fields, along with extensive experience in data science, machine learning, programming, statistical analysis, and data management. Expertise across multiple areas, including advanced analytics, AI, workflow reproducibility, and software engineering is strongly preferred.
Requires STEM degree, Security+ certification and 15+ years of experience.
Reverse Engineer
This role involves performing technical analysis of malicious binaries through controlled execution and static assembly code analysis to determine functionality, capabilities, adversary infrastructure links, and indicators of compromise. The analyst produces documentation that supports malware detection, signature development, and mitigation efforts.
Requires STEM degree, CISSP and GIAC GREM or CREA certification, and 7+ years of experience.
