Do you have experience in Zero trust architecture design?, Do you have a Bachelor’s degree?, As a Cybersecurity Engineer III at Revolutional, you are a senior technical leader with 10+ years of cybersecurity engineering depth and the strategic range to match. You design and integrate security architectures across complex federal enterprise environments - spanning Zero Trust, cloud, mobile, DevSecOps, AI/ML, and Post-Quantum Cryptography - and you lead teams through the full engineering lifecycle from CONOPS development to production deployment.

You operate at the intersection of architecture and execution. You produce strategic technology roadmaps, conduct proof-of-concept evaluations, identify security gaps, and translate operational requirements into implementable security controls. You are a force multiplier for the program - technically authoritative, methodical, and capable of leading engineering teams under real-world operational constraints., * Bachelor’s degree in Computer Science, Engineering, Information Systems, Cybersecurity, or related field; OR 10 years of cybersecurity engineering work experience in lieu of degree

• Minimum 10 years of work experience in cybersecurity engineering and/or cybersecurity project management
• 2 or more years of leadership experience managing cybersecurity engineering teams
• Secret eligibility required, * Experience developing and integrating cybersecurity designs for systems and networks, including system security context, CONOPS, and baseline security requirements documentation
• Hands-on experience implementing Zero Trust Architecture principles in enterprise environments
• Experience developing strategic technology roadmaps and conducting market research and proof-of-concept evaluations for cybersecurity tools
• Experience with cloud security engineering across at least one CSP type: IaaS, SaaS, or PaaS
• Experience or knowledge integrating cybersecurity with AI or Generative AI systems
• Experience supporting DevSecOps pipeline security integration
• Working experience or knowledge with NDR platforms, network modeling, and behavior analysis technologies
• Experience with SIEM, SOAR, and CTI technologies
• Experience with secure authentication and SSO engineering
• Mobile security engineering experience or knowledge: MTD, MDM, and/or MAM security controls
• Experience or knowledge of Post-Quantum Cryptography concepts, including one or more of: certificate lifecycle management, cryptographic asset discovery, PQC-enabled protocol design, quantum-ready encryption system development, or cryptographic inventorying
• Understanding of core network protocols: TLS, X.509, BGP, DHCP, IPsec, DNSsec, and related standards
• 2 or more years of experience with network packet capture tools such as Wireshark, tcpdump, or nmap
• Proficiency scripting and automating administrative functions using PowerShell and/or Python
• Experience with vulnerability scanning tools for OS, web application, and database assessments, * Technically authoritative across a wide engineering domain - you make sound architectural decisions and your designs hold up under operational and compliance scrutiny
• Strategic thinker who builds roadmaps that are executable, not aspirational - grounded in mission requirements and real-world constraints
• Effective engineering leader who develops team capability, manages delivery, and holds quality standards without micromanaging
• Translates complex technical architectures into clear documentation and stakeholder communications, * CISSP, CISSP-ISSAP, CISSP-ISSEP, CCSP, CCNA, GIAC (any), SSCP, or CompTIA Security+ (or equivalent as approved), * Multiple certifications from the required list, particularly CISSP-ISSEP (engineering-focused) or CCSP for cloud security depth
• Hands-on PQC implementation experience including NIST PQC algorithm deployment (CRYSTALS-Kyber, CRYSTALS-Dilithium, SPHINCS+)
• Experience engineering AI/ML security controls or red-teaming AI systems in a federal environment
• Familiarity with CISA, NIST, or NSA Zero Trust maturity model frameworks and federal ZTA implementation guidance
• Experience with industrial control system (ICS) or OT security engineering
• Active Secret clearance
