POSITION SUMMARY

This role will be pivotal in advancing the company's mission of delivering secure, reliable, and innovative software solutions for U.S. government and DoD clients. The Cybersecurity Engineer serves as the resident security subject-matter expert embedded within the DevOps squad, owning the security compliance posture for software deployed in federal, DoD, and other highly regulated secure environments. The ideal candidate brings direct, hands-on experience operating within secure federal technology environments and a strong working knowledge of the security frameworks, tooling, and authorization processes that govern government-hosted systems. This individual will drive RMF/ATO lifecycle management, STIG implementation, vulnerability remediation, and DevSecOps integration across Sphera's product lines, ensuring that all systems maintain continuous compliance and readiness for deployment in secure government operating environments.

KEY RESPONSIBILITIES

• Lead cybersecurity for software deployed in secure federal and DoD environments, ensuring compliance with applicable government security policies, access requirements, and accreditation expectations.

• Execute RMF activities, including system categorization, security control selection, implementation, assessment, and ATO documentation for federal or DoD-hosted systems.

• Implement, configure, and validate STIGs across layers using DISA-approved or equivalent government security tooling.

• Mitigate OWASP Top 10 and application-layer vulnerabilities across services.

• Monitor security controls, scan vulnerabilities, and audit systems, producing reports and coordinating remediation with development and DevOps.

• Manage POA&Ms, coordinating with government security stakeholders, ISSMs, and internal teams to track and resolve open findings.

• Support FedRAMP and FISMA compliance, aligning controls with NIST SP 800-53 Rev. 5.

• Integrate security tooling and automated checks into CI/CD pipelines, advancing DevSecOps maturity.

• Collaborate with engineers and the Principal Solutions Architect to conduct threat modeling, security design reviews, and application-level security assessments.

• Maintain System Security Plans (SSPs), security architectures, and supporting ATO documentation packages in alignment with federal and DoD requirements.

• Lead incident response activities for security events affecting systems deployed in secure government environments, coordinating with customer cybersecurity personnel and internal stakeholders.

• Monitor SIEM alerts, analyze logs, and investigate anomalous activity.

• Evaluate the security posture of third-party integrations, vendor tools, and emerging technologies for adoption in secure federal or DoD environments.

• Embed security requirements into sprint planning, feature development, and release processes with the TPM, engineering squads, and product owners.

• Stay informed on evolving federal, DoD, DISA, and agency-specific security policies, DISA guidance updates, and emerging threats, and proactively communicate their impact to the engineering organization.

QUALIFICATIONS & EXPERIENCE

• U.S. citizen required; active DoD security clearance or ability to obtain and maintain one due to secure federal enclave access.

• Minimum 3-5 years of hands-on cybersecurity experience in a federal, DoD or similarly regulated secure environments.

• Strong working knowledge of secure federal or DoD environments, including segmented networks, access control, approved software baselines, and applicable security requirements.

• Experience supporting or leading RMF processes, including ATO package preparation and submission for federal or DoD systems.

• Proficiency in applying STIGs using DISA-approved tools (SCC, STIG Viewer, Nessus/ACAS) or comparable vulnerability and compliance platforms.

• Solid understanding of FedRAMP Moderate and FISMA compliance, with ability to map security controls to NIST SP 800-53 Rev. 5.

• Experience with vulnerability management tools (e.g., Tenable.sc, Nessus, ACAS) in federal or DoD environments.

• Familiarity with enterprise security tools including SIEM, IDS/IPS, and network security controls.

• DevSecOps experience, including integrating SAST, DAST, and SCA scanning into CI/CD pipelines using Azure DevOps, Jenkins, or equivalent tools.

• Familiarity with PKI, CAC/PIV authentication, and certificate management in federal or DoD environments.

• Strong written and verbal communication skills to translate complex security findings into actionable guidance for engineering teams and brief government stakeholders.

• DoD 8570/8140 compliant certification at IAT Level II or higher (e.g., CompTIA Security+, CISSP, CEH, CAP, or equivalent).

• Bachelor’s degree in Computer Science, Information Security, Cybersecurity, or a related field, or equivalent practical experience.

• Experience working in segmented networks with an understanding of federal, DoD, or similarly regulated infrastructure and security requirements.

PROFESSIONAL SKILLS

• Proven time management, organizational and follow-up skills to meet deadlines.

• Work effectively, independently, and in a dynamic team environment.

• Excellent interpersonal skills.

• Must be willing to learn new technologies and processes as needed.
