## Description

Argonne Security is seeking a Physical security focused Data & Systems Engineer specializing in access-control modernization, Lenel/DSX analytics, PACS configuration, and enterprise security data standardization. Skilled in C/Java, Python, SQL, Power BI, and ETL pipelines, with a proven ability to automate processes, integrate multi-source PACS data, and build dashboards that surface modernization progress, risk posture, and asset readiness.

 * To perform the essential functions of this position successful applicants must provide proof of U.S. citizenship, which is required to comply with federal regulations and contract.
 * Must be able to obtain and maintain a DOE "Q" clearance.

Core Responsibilities

Access Control Modernization (DSX * Lenel OnGuard)

 * Analyze DSX door, reader, panel, and hardware data to support consolidation of legacy PACS systems into Lenel OnGuard.
 * Map DSX objects to Lenel equivalents, ensuring accurate hardware relationships, access-control logic, and migration-ready datasets.
 * Standardize naming conventions, door identifiers, and hardware mappings to enable clean PACS migration.
 * Prepare structured Lenel import datasets (doors, readers, access levels, badges, timezones, panel mappings).
 * Validate DSX * Lenel mappings using SQL queries, DSX exports, and physical-security field documentation.
 * Modernize physical-security processes, data flows, and system configurations to strengthen overall security posture.

Lenel OnGuard Configuration & SQL Development

 * Work directly with Lenel SQL tables (AccessLevels, Readers, Hardware, Panels, Timezones, Badge, Personnel) to build audit-ready PACS datasets.
 * Configure Lenel hardware objects: readers, controllers, doors/locks, I/O relationships, panel communication paths, and timezones.
 * Develop Lenel workflows for badge provisioning, access-level assignments, and automated data-quality checks.
 * Build SQL queries and stored procedures to identify misconfigured access levels, missing readers, offline hardware, badge anomalies, and DSX/Lenel mismatches.
 * Collaborate with Physical Security and vendors to validate configuration changes and ensure DOE compliance.

Security Analytics, Reporting & Dashboards

 * Build Power BI dashboards showing modernization progress, hardware readiness, and DSX * Lenel migration status.
 * Develop SQL-driven reporting pipelines integrating DSX exports, Lenel SQL Server data, and supplemental Excel/S3 sources.
 * Produce audit-ready reports for Physical Security and Facilities across large, distributed campuses.
 * Implement automated data-quality checks for duplicate door IDs, missing hardware relationships, incorrect badge/access mappings, and PACS cleanup tasks.

Secure Software Engineering & ETL

 * Develop backend/frontend components supporting physical-security analytics, geospatial asset mapping, and AI-driven exploration.
 * Build Python/SQL ETL pipelines maintaining up-to-date inventories of doors, readers, panels, and access levels across DSX and Lenel environments.
 * Create performance-critical ingestion modules for reliable processing of complex JSON and nested security data.

Ability to model Argonne's core values of impact, safety, respect, integrity, and teamwork.
