Application Security Architect at Oceaneering – Houston | Jobyssey

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

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, 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.

Security Defect Management & Risk Visibility

Implement centralized tooling to:
- Aggregate SAST, SCA, DAST, and pen 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)
- % 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.
