Senior Data Security Engineer
Dallas, IA - USA
Job Summary
HF Sinclair is seeking a Senior Data Security Engineer in Dallas Texas. Serves as the technical authority responsible for defining and operationalizing the enterprise data security execution model. This role is accountable for translating data security intent (governance privacy policy) into repeatable enforceable and observable controls across production environments with particular focus on application API analytics & automation and AIdriven data access paths.
As the first dedicated data security engineering role this position provides handson technical leadership while simultaneously shaping architecture standards maturity targets and implementation sequencing. The role partners closely with Cybersecurity Architecture Cloud Engineering Data & Analytics and Application teams to ensure data security capabilities are designed for execution speed not theoretical completeness.
This role intentionally prioritizes reducing current exposure before enabling advanced use cases. Secure analytics and AI are treated as outcomes of maturity not parallel initiatives.
Data Security Execution (Primary)
- Define and maintain data security reference architectures and control patterns focused on:
- Applicationmediated data access
- API exposure and servicetoservice data flows
- Automation orchestration and machinedriven access AI/ML workloads etc.
- Define and monitor data security capability maturity across structured unstructured and applicationcentric domains aligned to the enterprise cybersecurity taxonomy.
- Translate architectural intent into implementable standards and technical design criteria that engineering teams can execute without ambiguity.
- Define & maintain enterprise data classification labeling & protection standards across structured & unstructured data.
- Participate in architecture reviews & modernization initiatives to ensure secure data handling requirements are incorporated into application cloud analytics integrations & automation solutions
Data Exposure Reduction & Control Engineering
- Lead technical efforts to identify and reduce existing data exposure with emphasis on:
- Access path patterns and permissions across SaaS cloud service third-party integrations and business applications
- Application and API data flow monitoring
- Data protection capabilities supporting classification monitoring access governance & data loss prevention requirements
- Design and implement controls that operate at execution points including:
- Data access monitoring tied to application context
- Enforcement patterns beyond static DLP or perimeter controls
Secure Enablement of Analytics and AI
- Serve as the technical advisor for securing data used in analytics automation and AI initiatives.
- Collaborate with peer IT and business teams to embed security controls into data pipelines feature stores and model interaction layers.
- Explicitly sequence AIrelated security work to avoid increasing risk through premature enablement.
Selective Cloud Security Engineering Support (Secondary)
- Provide targeted cloud security engineering support where it directly impacts data exposure including cloud storage data platforms SaaS and identitydriven data access patterns.
- Collaborate with technical peers on generalized cloud posture management particularly where it directly reduces data risk.
Operationalization & Incident Readiness
- Define datacentric detection and response patterns to improve monitoring.
- Partner with SOC and Engineering teams to ensure response workflows are realistic tested and actionable.
Role Relationships & Boundaries
- Cybersecurity Architect: Peer relationship. Joint ownership of architecture coherence; this role owns data security execution detail while the Architect owns enterprisewide alignment.
- Data Governance & Privacy: Consumers of intent and constraints; this role owns how those constraints are enforced in production.
- Cloud & Application Engineering: Execution partners; this role defines what secure means in practice and helps teams implement it.
