Security Engineer

Overview

Steampunk is searching for a Security Engineer to support a government customer. This role is a strong fit for hands-on engineers, including software developers, system administrators, and technical subject matter experts, who want to apply their technical depth to cybersecurity. Your primary responsibility will be to ensure that the security posture documented in each system's security authorization is implemented and maintained at an acceptable level of risk. Success in this role takes initiative, organization, a customer-service mindset, and the flexibility to adapt in a fast-paced, fluid environment. You'll communicate clearly and decisively with all levels of the organization, solve practical problems, and exercise sound judgment with sensitive and confidential information.

As a Security Engineer, you'll be the technical expert that development and operations teams rely on to resolve vulnerabilities. Your experience building software or running systems is what makes you effective: you'll understand what a finding means in the code or configuration, separate real risk from noise, and recommend fixes that teams can realistically implement. Rather than performing remediation yourself, you'll typically guide teams through it, tracking issues to closure and keeping systems compliant with federal requirements. If you want to keep coding, you'll find regular opportunities to do so, from building tools that automate compliance work to reviewing code (including AI-generated code) for vulnerabilities and validating fixes. You'll also have access to the latest AI models to speed up development and vulnerability responses.

Contributions

• Review the security architecture of new systems, applications, and technologies, drawing on your development and infrastructure experience to identify and mitigate potential risks

• Recommend appropriate mitigation measures and advise on design trade-offs, weighing potential impact against cost and benefit

• Evaluate waivers and risk acceptance memos, bringing technical judgment to the management of system risk

• Monitor the gates in the System Lifecycle Management (SLM) process and brief the customer on outstanding issues and risks before concurrence on system readiness

• Participate in DevSecOps activities for assigned systems, helping teams integrate security into their Agile and DevOps processes

• Proactively ensure security requirements are included throughout the development lifecycle (Waterfall, Agile, or DevSecOps)

• Ensure configuration management (CM) processes are followed so that changes do not introduce new security risks

• Conduct an annual assessment in accordance with the DHS Information Security Performance Plan

• Review and update security authorization documents as needed and on the required schedule

• Perform system self-assessments as part of the customer's Ongoing Authorization program

• Provide audit support for assigned systems (financial, OMB Circular A-123, FISMA, DHS, internal, and others) before, during, and after each audit

• Maintain knowledge of the hardware and software inventory within authorization boundaries

• Use DHS-mandated enterprise information assurance (IA) compliance tools

• Specialized knowledge and experience evaluating system, network, or infrastructure security controls against FISMA, FIPS, and NIST requirements

• Knowledge and experience with vulnerability scanning execution, assessment, and analysis

• Knowledge and experience with application security, database security, and network security

• Knowledge and experience using Splunk in an enterprise environment

• Ability to assess and weigh current and evolving security threats in an operational environment

• Excellent communication and interpersonal skills, including the ability to explain technical risk to both engineers and non-technical stakeholders

Preferred

• Hands-on background in software development, system administration, or DevOps engineering

• An information technology certification related to your subject matter expertise, such as a security certification (e.g., CISSP, CGRC, CSSLP, CCSP, CompTIA Security+ or SecurityX), a development certification (e.g., Oracle Certified Professional: Java SE Developer, AWS Certified Developer – Associate), or a systems or cloud certification (e.g., RHCE, CKA, AWS Certified Security – Specialty)

• Proven experience as an Information Security Engineer, including current experience providing security support to DHS

• In-depth knowledge of federal cybersecurity regulations and standards

• Experience with scripting and automation (e.g., Python, PowerShell, or Bash)

• Strong understanding of security infrastructure, risk management, and compliance

• Proficiency in security tools, technologies, and best practices
