Cybersecurity Engineer

Overview

We are looking for a Cybersecurity Engineer to design and guide secure system architectures that can achieve and sustain federal cybersecurity authorization. This role focuses on translating complex regulatory frameworks into practical architecture patterns that enable platforms and applications to meet the rigorous expectations of federal security programs.

You will operate at the intersection of security architecture, Dev Sec Ops , and Governance, Risk, and Compliance (GRC)–ensuring systems are architected for authorization success while also guiding the documentation, risk management, and programmatic processes required to achieve and maintain compliance.

This role is ideal for an experienced security architect or senior federal cybersecurity professional who understands both federal authorization frameworks and modern cloud/software architectures, and who can bridge engineering teams, security governance functions, and government stakeholders.
