About the Organization
Now is a great time to join Redhorse Corporation. We are a solution-driven company delivering data insights and technology solutions to customers with missions critical to U.S. national interests. We’re looking for thoughtful, skilled professionals who thrive as trusted partners building technology-agnostic solutions and want to apply their talents supporting customers with difficult and important mission sets.
About the Role
Redhorse transforms the way government uses data and technology. To support this mission, we are seeking a Senior Cybersecurity Engineer to protect and defend critical enterprise and mission IT infrastructures. In this role, you will be at the forefront of securing complex, multi-classification architectures, ensuring that the data and technology powering our nation's most sensitive missions remain resilient against evolving threats. You will have a direct impact on the security posture of cloud environments and classified enclaves, bridging the gap between high-level policy and technical implementation.
Key Responsibilities
Secure enterprise and mission IT infrastructures across diverse operating systems, networks, and web/database applications.
Manage and harden storage, boundary/perimeter devices, and logging/monitoring solutions within cloud environments (e.g., C2S) and classified enclaves.
Implement policy-based protections for data flows and network boundaries across complex, multi-classification architectures.
Support security certification and accreditation activities (RMF) and lead the development of required security documentation.
Perform ad-hoc penetration testing, formal red/blue team exercises, and compliance assessments of classified Federal systems.
Identify innovative protection strategies that align with budget and infrastructure constraints.
Communicate and brief technical risks and mitigation options to both technical and non-technical stakeholders.
Prioritize and coordinate cybersecurity workflows in fast-paced, high-stakes environments.
Required Experience/Clearance
Active TS/SCI clearance with Polygraph.
10+ years of experience in cybersecurity engineering or information assurance.
Proven experience securing cloud environments (AWS/C2S/Azure) and classified enclaves.
Demonstrated expertise in network boundary protection and policy-based data flow implementation.
Experience with the Risk Management Framework (RMF) and the security accreditation process.
Hands-on experience with penetration testing tools and red/blue team methodologies.
Must possess and maintain relevant cybersecurity professional certification(s) (e.g., CISSP, CEH, Security+, or equivalent DoD 8140/8570.01-M certification).
Desired Experience
Familiarity with DataBricks, GitLab, or Jira for managing security workflows.
Experience with advanced logging and monitoring solutions like Splunk or ELK stack.
Knowledge of Spark or other big data technologies within a secure environment.
Advanced degree in Cybersecurity, Computer Science, or a related technical field.
Previous experience supporting Intelligence Community (IC) or Department of Defense (DoD) customers.
The salary range provided for this position represents the anticipated base salary for successful candidates. Actual compensation will be determined based on a variety of factors, including relevant experience, education, certifications, skills, security clearance level, geographic location, market conditions, and internal equity. In addition to base salary, eligible employees may participate in Redhorse's comprehensive benefits programs and may be eligible for performance-based or other incentive compensation, where applicable.
