POSITION OVERVIEW
SteerBridge is seeking a Security Architect to define the security architecture and compliance strategy for a mission-critical Defense Aviation platform running in AWS GovCloud for federal customers. This role owns the security blueprint—controls, identity, zero-trust access, monitoring, and authorization strategy—for environments supporting federal aviation operations.
The architect will work directly with solutions architects, security and cloud engineers, data teams, and stakeholders to translate DoD security requirements into enforceable, well-architected designs and to guide the platform toward and through authorization (ATO).
This role stays close to implementation. The ideal candidate sets security standards, designs control frameworks, reviews architectures, and guides engineers in implementing defense-in-depth and zero-trust access.
This is a hybrid position based in Vienna, VA.
Key Responsibilities
Security Architecture and Strategy
- Define the security architecture for AWS GovCloud workloads spanning identity, zero-trust access, network segmentation, encryption, monitoring, and data protection
- Design and own the zero-trust access architecture, leveraging Zscaler (ZTNA/SASE) to broker secure access to applications and infrastructure
- Design defense-in-depth control frameworks aligned to DoD and DISA requirements
- Produce security architecture documentation, control mappings, and decision records
- Establish security standards and reference patterns for engineering teams
Compliance and Authorization
- Lead security alignment with DoDI 8510, CNSSI 1253, STIGs, DoD CC SRG, and ATO and authorization processes.
- Define control implementation and evidence strategies for audits and assessments
- Assess and communicate security risk to technical and non-technical stakeholders
- Guide POA&M development and remediation prioritization
Design Governance and Guidance
- Review architectures and designs to ensure security is embedded from the outset
- Set standards for least-privilege IAM, zero-trust secure access (Zscaler/ZTNA), and hardened baselines
- Guide engineers implementing security controls, detection, and response capabilities
- Lead security and threat-model reviews
Collaboration and Leadership
- Partner with cloud and solutions architects to ensure secure-by-design platforms
- Advise leadership on security strategy, posture, and risk trade-offs
- Mentor engineers and promote a strong security culture
Required Qualifications
- U.S. Citizenship required (for clearance purposes)

- Strong command of security frameworks including DoDI 8510, CNSSI 1253, STIGs, DoD CC SRG, DISA STIGs
- Experience guiding systems through ATO and authorization in DoD environments
- Strong understanding of defense-in-depth, zero-trust principles, and least-privilege design
- Ability to produce clear security architecture documentation and risk assessments
- Experience leading security across multidisciplinary teams
- Skill in determining how a security system should work (including its resilience and dependability capabilities) and how changes in conditions, operations, or the environment will affect these outcomes.
- Skill in translating operational requirements into protection needs (i.e., security controls).
- Skill in applying cybersecurity methods, such as firewalls, demilitarized zones, and encryption.
- Ability to apply network security architecture concepts including topology, protocols, components, and principles (e.g., application of defense-in-depth).
- Ability to apply an organization’s goals and objectives to develop and maintain architecture.
- One or more of the following:
- Certified Information Security Manager (CISM)Certified Information Systems Security Professional (CISSP)

- Extensive experience in AWS GovCloud or other federal or regulated environments
- Masters or PHD in Information Technology, Cybersecurity, Computer Science, Information Systems, Data Science, or Software Engineering.
- Deep experience architecting Zscaler or comparable ZTNA/SASE solutions and integrating them with identity and conditional access
- Experience with continuous monitoring, SIEM strategy, and incident response programs
- Experience with data security and protection of analytics and Medallion platforms
- Senior certifications such as CCSP; or AWS Security Specialty
