Application Security Architect

About the role

This role is responsible for building and operationalizing Oceaneering’s enterprise application security program, embedding security into the software development lifecycle (SDLC), CI/CD pipelines, and developer ecosystem. The position offers a hybrid work environment, combining virtual work with occasional in-office presence in Houston.

Responsibilities

• Define and govern application security requirements, controls, and assurance activities embedded within the SDLC model.
• Partner with the Software Center of Excellence (SCOE) to integrate security without duplicating ownership of engineering platforms, tooling, or development standards.
• Collaborate with Engineering, SCOE, and Cybersecurity leadership to reduce software supply chain risk, implement DevSecOps practices, and enforce secure development standards aligned to Zero Trust principles.
• Application Security Program Leadership:
  • Establish and lead an enterprise Application Security (AppSec) governance framework, including Secure SDLC and vulnerability management policies.
  • Drive adoption and enforcement of secure coding standards, security testing requirements, and remediation SLAs across all application teams.
  • Build a risk-based AppSec roadmap aligned to business criticality, “crown jewel” applications, and regulatory requirements.
  • Serve as the central authority for secure software supply chain controls and application risk posture.
• Developer Security & Environment Strategy:
  • Design and implement a secure developer program addressing:
    • Developer workstations vs. business PCs.
    • Removal of excessive local admin privileges.
    • Elimination of unmanaged builds and compilers.
  • Lead transformation to secure developer environments, including:
    • Virtualized or hybrid development models.
    • Centralized build infrastructure.
    • Controlled developer access aligned with Zero Trust.
  • Reduce risk associated with:
    • Local code storage.
    • Unvetted open-source dependencies.
    • Developer endpoint compromise.
• DevSecOps & CI/CD Pipeline Security:
  • Architect and implement a secure CI/CD pipeline with embedded controls:
    • SAST, SCA, DAST integration.
    • Secrets scanning.
    • Artifact integrity and provenance validation.
    • Pipeline enforcement (GitHub → CI → Artifact Repository → Test Environments).
  • Ensure no production artifacts bypass secure pipelines and all builds are traceable and verified.
  • Partner with SCOE to standardize DevSecOps tooling and pipeline templates enterprise-wide.
• Application Security Testing & Validation:
  • Establish an enterprise-wide application testing program, including:
    • Static (SAST), Dynamic (DAST), and Software Composition Analysis (SCA).
    • Manual and automated penetration testing for critical applications.
  • Expand testing beyond web applications into embedded, ICS, and custom software platforms.
  • Build a structured penetration testing program for crown jewel applications, including third-party partnerships and remediation tracking.
  • Ensure security validation is embedded in CI/CD gates before production deployment.
• Threat Modeling & Secure Architecture:
  • Lead implementation of threat modeling capabilities for critical applications to identify design flaws early in the SDLC.
  • Define and enforce secure-by-design principles across engineering teams.
  • Collaborate with architects and engineering to integrate Zero Trust architecture, segmentation, and secure design patterns.
• Security Defect Management & Risk Visibility:
  • Implement centralized tooling to:
    • Aggregate SAST, SCA, DAST, and penetration test findings.
    • Provide a single pane of glass for application risk.
    • Drive prioritization and remediation of vulnerabilities based on business risk and technical severity.
  • Establish KPIs such as:
    • Mean time to remediate (MTTR).
    • Percentage of critical vulnerabilities fixed before release.
    • Coverage of testing across applications.
• Developer Enablement & Training:
  • Build and lead a role-based application security training program for developers, architects, and QA.
  • Provide:
    • Secure coding guidance (language-specific).
    • Secure development playbooks and reference architectures.
  • Partner with SCOE to embed security practices into daily developer workflows and pipelines.
• Integration with Software Center of Excellence (SCOE):
  • Expand the SCOE charter to include DevSecOps governance and enforcement.
  • Drive:
    • Adoption of enterprise CI/CD standards.
    • Secure pipeline templates.
    • Standardized DevSecOps toolchain.
  • Improve visibility and enforcement of security policies across all development teams.

Requirements

• Bachelor’s degree in Information Technology, Cybersecurity, Computer Science, Engineering, or related field, or equivalent experience.
• Minimum 3 years of experience supporting security monitoring, SIEM, or security engineering platforms.
• Minimum 1 year of experience administering Splunk Enterprise.
• Minimum 1 year of experience supporting Cribl or similar log management technologies.
• Minimum 1 year of experience with Syslog architecture and log ingestion technologies.
• Minimum 1 year of experience supporting Managed Detection and Response (MDR) services or Security Operations Centers.
• Minimum 1 year of experience working with Windows, Linux, network, and cloud log sources.
• Familiarity with Operational Technology (OT) and Industrial Control System (ICS) environments.

Qualifications (Preferred)

• Splunk Certified Administrator or Splunk Certified Architect certification.
• Experience with industrial networking and OT/ICS environments.
• Experience integrating enterprise logging platforms with MDR providers.
• Knowledge of NIST Cybersecurity Framework, IEC 62443, or ISA/IEC industrial security standards.
• Experience with scripting and automation using PowerShell, Python, or similar tools.
• Familiarity with Microsoft Azure and cloud security monitoring.
