At Evlos Technology, we’re Solvers at heart. We bring together talented people, evolving technology, and innovative ideas to solve complex problems and support meaningful customer missions.
Evlos is seeking an experienced Information Systems Security Engineer (ISSE) to join our team. In this role, you will help design, assess, and secure complex systems and networks spanning multiple enclaves with varying data protection and classification requirements.
The ideal Solver will have a strong understanding of distributed architectures, cloud-based systems, DoD cybersecurity requirements, and security engineering for Big Data environments. You’ll work closely with technical teams and government stakeholders to evaluate risk, guide secure system design, and ensure systems meet required security and accreditation standards.
We’re looking for someone who is technically strong, collaborative, adaptable, and comfortable taking ownership—whether that means following an established process or developing a defensible solution when one doesn’t yet exist.
This position requires a hybrid work schedule in San Antonio, Texas, with flexibility to accommodate customer and mission needs.

Create, review, and edit authorization and accreditation documentation for completeness, accuracy, and compliance with federal and DoD policies.

Utilize vulnerability management systems, automated security scanning tools, and system authorization/accreditation record systems.
Interpret and apply Defense Information Systems Agency (DISA) Security Technical Implementation Guides (STIGs) and Security Requirements Guides (SRGs).
Provide security planning, assessment, risk analysis, and risk management support.
Recommend system-level solutions to address security requirements and guide development teams in achieving required security posture.
Support government stakeholders in establishing and enforcing trusted relationships among external systems and architectures.
Apply knowledge of Information Assurance policies, procedures, and workforce requirements to design, develop, and implement secure networking, computing, and enclave environments.
Facilitate information exchanges and collaborate with technical and non-technical stakeholders to gather necessary security and authorization information.
Follow established security processes when applicable and develop and execute defensible processes when established guidance does not exist.
Work effectively both independently and as part of a collaborative technical team.
Perform other duties as assigned.
Minimum Qualifications
Active U.S. Government Secret security clearance required.
U.S. citizenship is required.

Experience implementing DoD system authorization/accreditation processes, with RMF experience preferred.
Working knowledge of the TCP/IP suite of protocols and services, computer architectures, and network topologies.
Understanding of the underlying framework, control inheritance, and artifact generation associated with NIST SP 800-53.
DoD 8140 IAT Level II compliant certification, such as Security+, SSCP, CCNA Security, GSEC, or other qualifying certification.
Experience with DISA STIGs and SRGs, vulnerability management systems, mitigation and compliance processes, and automated security scanning tools.
Hands-on experience navigating RMF workflows, uploading artifacts, and managing Plans of Action and Milestones (POA&amp;Ms) in eMASS, Xacta, or an equivalent RMF system of record.
Strong analytical, communication, collaboration, and problem-solving skills.
Ability to work effectively both independently and as part of a team.
