Role Title: Security AI Operations Engineer

Organization: Value Added Services / Security Operations

Role Overview The Security AI Operations Specialist bridges automated AI systems and human security operations. This role is responsible for the day-to-day supervision, quality control, and execution of AI-assisted security workflows.

Working alongside the Security Automation & AI Engineering team, the Specialist manages "Human-in-the-Loop" (HITL) triage queues, maintains and updates knowledge bases feeding generative models, audits AI outputs for accuracy, and ensures prioritized investigation tasks are routed seamlessly to front-line security analysts and consultants.

Key Responsibilities

• AI Workflow Supervision & Human-in-the-Loop (HITL) Routing
• Review and validate low-confidence alert enrichments, threat summaries, and triage recommendations generated by AI agents.
• Assign, dispatch, and track complex security investigations, policy changes, and incident response playbooks to appropriate Tier 2/3 analysts and consultants.
• Serve as the operational escalation point when automated pipelines encounter exceptions, edge cases, or platform integration errors.
• Knowledge Base & Prompt Lifecycle Management
• Curate, clean, and organize internal runbooks, standard operating procedures (SOPs), threat intelligence, and product documentation stored in Amazon Bedrock Knowledge Bases and Amazon OpenSearch Service.
• Audit AI retrieval quality and document gaps in knowledge coverage that lead to model hallucinations or poor responses.
• Perform routine prompt adjustments and template maintenance, submitting structured enhancement tickets to engineering when underlying code changes are required.
• Quality Assurance & Performance Auditing
• Regularly audit AI-generated outputs (incident summaries, triage context, customer reports) against human analyst benchmarks to ensure high fidelity and operational safety.
• Identify recurring false positives or hallucination patterns, collaborating directly with automation engineers to refine model guardrails and prompt evaluation datasets.
• Track and report on operational KPIs, including Mean Time to Respond (MTTR), task assignment velocity, and analyst AI adoption.
• Team Enablement & Operational Feedback
• Train security analysts and services teams on prompt best practices, effective use of internal AI copilots, and feedback submission workflows.
• Gather front-line feedback and feature requests from security practitioners to help shape the automation engineering roadmap.
• Sales
• Partner with the Sales Engineering team to develop and deliver Value-Added Services (VAS) proof-of-values (POVs), clearly demonstrating the business value and impact of these services.
• Collaborate with Account teams to accelerate time-to-value for Thales solutions among non-VAS customers, strengthening customer adoption, retention, and renewal outcomes.

• Experience: 3–5+ years in a Security Operations Center (SOC), Managed Security Services (MSSP), IT Service Management (ITSM), or technical workflow coordination role, including 2+ years working with AI/Gen AI-enabled tools or workflows.
• Cybersecurity Foundation: Working knowledge of security operations, threat lifecycle, alert triage, WAF, API security, and common security frameworks (e.g., MITRE ATT’CK, NIST).
• AI & Workflow Tooling: Practical experience interacting with generative AI tools, prompt workflows, and enterprise ticketing/orchestration platforms (e.g., Jira, ServiceNow, PagerDuty, or SOAR platforms).
• Cloud & Search Interface Familiarity: Working comfort navigating the AWS Management Console (specifically Amazon Bedrock, Amazon OpenSearch Dashboards, and CloudWatch metrics).
• Communication & Documentation: Strong technical writing skills with experience authoring security runbooks, SOPs, and structured process documentation.
