Our team is a collaborative group of engineers who value technical excellence, clear communication, and diverse perspectives. We work closely across disciplines to solve complex mission challenges and support one another through mentorship, knowledge sharing, and continuous learning. We take pride in building a supportive environment where engineers at all levels can grow, contribute meaningfully, and develop long term careers in national security. _Please Note: Due to the classified nature of the work being performed, this position does not offer any virtual or telecommute working options. Applicants_ are _encouraged to apply, only if they are willing to work on-site._ What You'll get to Do: A Cybersecurity Systems Engineer (CSSE) ensures cyber survivability attributes are implemented in system designs as it assesses/evaluates the customers'/stakeholders' cybersecurity requirements to decompose, derive, and refine the system's cybersecurity requirements at all levels to drive the built-in cybersecurity protections to the architecture and design. The CSSE also guides/supports the security layout / architecture and influences the security tools selection and development. The CSSE evaluates/assesses the proposed and realized implementations to identify security risks, attack surface, and verify the cybersecurity protections from the design are realized and integrated. The CSSE guides/supports the development of verification efforts to ensure the cybersecurity protections / capabilities are functional, effective, and complete. A CSSE supports the definition of security governance, and risk management. The selected candidate will be required to work on-site, full-time at our San Antonio, TX site. The individual will perform the following duties on a day-to-day basis in support of the program: + Implement and review cyber requirement decomposition, derivation, and flow down + Implement and review traceability of cyber requirements throughout a spec tree architecture + Support the architecture and design of baked in cybersecurity requirements and protections + Implement and review traceability of cyber requirements to the design & its models + Implement and review the application of cyber security profile stereotypes to a Model Based System Engineering (MBSE) Architecture + Provide cybersecurity system engineering implementation guidance and oversight to technical teams/implementers + Review and Assess stakeholder security objectives, protection needs and concerns, security requirements, and associated verification/validation methods + Implement, review and assess cybersecurity system requirements verification/validation methods + Identify and/or assess vulnerabilities and susceptibility to life cycle disruptions, hazards, and threats + Provide security considerations to inform systems engineering efforts with the objective to reduce errors, flaws, and weakness that may constitute security vulnerability leading to unacceptable asset loss and consequences + Identify, quantify, and evaluate the costs/benefits of security functions and considerations to inform analysis of alternatives, engineering trade-offs, and risk treatment decisions + Author, support and maintain cybersecurity program documentation & RMF package documentation: Cybersecurity Strategies, System Security Plans, Continuous Monitoring Plans, Risk Assessment Report, Security Control Traceability Matrix, Plan Of Actions & Milestones, etc. + Perform other duties and directed ## Related Videos - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [ShapeShift: Reinventing Agile for a B2B SaaS Scale-Up](https://www.wearedevelopers.com/videos/1655-shapeshift-reinventing-agile-for-a-b2b-saas-scale-up) - [Thinking Differently - How to Make Money from Cyber Attacks & Cheats](https://www.wearedevelopers.com/videos/745-thinking-differently-how-to-make-money-from-cyber-attacks-cheats) - [What makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) - [Less Is More: How Lagom and Agile Can Create Harmonious Workflows](https://www.wearedevelopers.com/videos/1993-less-is-more-how-lagom-and-agile-can-create-harmonious-workflows) - [Cyber Security: Small, and Large!](https://www.wearedevelopers.com/videos/259-cyber-security-small-and-large) ## Related Articles - [9 Ways to Make Money Hacking](https://www.wearedevelopers.com/magazine/333-9-ways-to-make-money-hacking) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Events like RSAC Get You CISOs.
