Overview:

Join a team where innovation meets mission. Our AI, cloud, cyber, and modernization solutions save agencies thousands of hours, safeguard national security, and strengthen health and humanitarian missions worldwide. With 1,700+ team members, 1,500+ AI/data experts, and 100+ prime contracts, we deliver at scale and with purpose.

We’ve been recognized as a Top Workplace by the Washington Post for six straight years and named to the Inc. 5000 Fastest Growing Private Companies 13 of the past 14 years. Credence is a welcoming home for those looking to grow and contribute to positive change. We encourage all employees to expand beyond their boundaries, dive into important world-changing Federal challenges.

Credence has a pending need for Information System Security Engineers (ISSE) at multiple levels (Jr./Mid/Sr.) to support our work at various locations slated to begin mid-summer 2026. The ISSE is responsible for designing, developing, and integrating secure information systems. Working closely with architects, developers, and security teams, the ISSE ensures that security requirements are embedded throughout the system lifecycle - from initial design to deployment and maintenance. This role involves conducting threat modeling, implementing security architectures, and validating system compliance with applicable standards such as NIST, RMF, and DOW directives. The ISSE is instrumental in bridging the gap between cybersecurity policy and technical implementation.

Core Responsibilities include, but are not limited to:

  • Identify information protection needs for an IS and Network Environment
  • Define IS and Network Environment security requirements in accordance with applicable cybersecurity requirements
  • Design security architectures for use within the IS and Network Environment
  • Design and develop cybersecurity-enabled products for use within an IS and Network Environment
  • Integrate and/or implement security with Cross Domain Solutions (CDS) for use within an IS and Network Environment
  • Develop and implement security designs for new or existing network system(s). Ensure that the design of hardware, operating systems, and software applications adequately address cybersecurity requirements for the IS and Network Environment.
  • Design, develop, and implement network security measures that provide confidentiality, integrity, availability, authentication, and non-repudiation
  • Design, develop, and implement specific cybersecurity countermeasures for the IS and Network Environment
  • Develop interface specifications for the IS and Network Environment
  • Develop approaches to mitigate IS and Network Environment vulnerabilities and recommend changes to network or network system components as needed
  • Ensure that network system(s) designs support the incorporation of our customer's directed cybersecurity vulnerability solution
