Job Description

The Application Security Architect 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.

• Role provides the opportunity to work in a hybrid environment, working both virtually and in the Houston office when required.

Functions

RESPONSIBILITIES

• Define and govern application security requirements, controls, and assurance activities embedded within that model
• Partner with SCOE to ensure security is integrated without duplicating ownership of engineering platforms, tooling, or development standards
• Partner with Engineering, the Software Center of Excellence (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 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, IC/ICS, and custom software platforms.
• Build structured pen 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 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.
