SECURITY ARCHITECTURE & ENGINEERING SME

Cybersecurity Architecture & Engineering Technical SME

Summary

Zermount Inc. is seeking a Cybersecurity Architect & Engineer SME who can create government solutions that will withstand even the most complex of IT and Cyber threats. The SME will support a federal client's enterprise cybersecurity and Continuous Authorization to Operate (cATO) initiative(s). The SME provides technical expertise, architectural recommendations, and engineering oversight across hybrid environments (on‑prem, cloud, and Cloud). The role focuses on designing secure enterprise architectures, engineering automated control assessments and evidence pipelines, and operationalizing zero trust and cATO capabilities.

You will coordinate with a dynamic team of thought leaders and experts to determine the right tools and methods to translate your client's IT needs and future goals into a plan that delivers secure and efficient solutions. You will assist the client through a critical approach to innovative solutions design, suggesting alternatives and tweaking capabilities to maintain a balance between security and mission needs. The candidate must have experience in delivering measurable improvements in security posture, automation, and compliance maturity.

Duties And Responsibilities

• Develop, maintain, and evolve the Enterprise Security Reference Architecture (ESRA).
• Provide architectural input to the organization's Cybersecurity Roadmap and Strategy, addressing:
• Continuous ATO (cATO) and automated control testing maturity. o Cloud security standards, compliance, and improvements to ATO timelines.
