What this job involves:

What your day-to-day will look like:

Vulnerability & Patch Management

• Identify vulnerabilities in BMS/OT connected assets; plan and validate remediation paths using vendor resources and security advisories.
• Test new software versions in a development environment; create and validate baselines prior to production deployment.
• Execute patching across BMS supervisory devices (JACE/JENEsys), HVAC equipment controllers, and building technology applications.
• Deploy approved software updates; support vendors and contractors through deployment; troubleshoot post-deployment issues.

Certificate & Credential Management

• Renew and manage certificates for JACE/JENEsys devices, BMS supervisory equipment, HVAC controllers, and server infrastructure supporting BMS applications.
• Sign and manage certificates for assets connected to the building/OT network; support certificate automation initiatives as they are introduced.

Product Onboarding & Technical Intake

• Review and validate device onboarding and offboarding across diverse networks, including IP address, MAC address, and certificate signing.
• Support new OT product onboarding end-to-end: lab testing, proof-of-concept validation, intake documentation, and asset scanning (e.g., Qualys, Tenable, or Phosphorus.io).

BMS Operations, Troubleshooting & Monitoring

• Troubleshoot and restore BMS systems and services including offline and unresponsive assets; review system alerts and coordinate incident triage and resolution.
• Monitor servers and storage supporting building technology applications; manage application backups and coordinate hardware replacements.
• Respond to support requests from facility teams, property managers, and facility management partners; troubleshoot application and network issues affecting building technology operations.

Application Technology Ownership & SME

• Manage overall technology health, stability, security, and compliance of BMS and building technology applications; oversee application lifecycle from onboarding through retirement and decommissioning.
• Serve as the primary Subject Matter Expert (SME) for application support, governance, enhancements, and risk management; manage vendor relationships for application maintenance and upgrades (e.g., Siemens, Distech, Lynxspring, or other Niagara-based controls contractors).

Project Implementation

• Support BMS controls cutovers, system startups, and new user group creation for new construction and retrofit projects.

Required Qualifications:

Education

• Bachelor's degree in Information Technology, Technical Management, or a related technical field (equivalent work experience will be considered in lieu of degree).

• Vulnerability identification and patch management for OT/BMS assets; working knowledge of Qualys, Tenable, or Phosphorus.io; full software release lifecycle management (testing, baseline, deploy, troubleshoot).
• PKI certificate lifecycle management for building control systems and supporting servers; compute infrastructure operations: server monitoring, backup management, DR testing.
• Experience as a technical SME for BMS or OT application ownership, including compliance and lifecycle governance.

Process & Governance Knowledge

• Experience submitting and tracking technology change requests in ServiceNow or equivalent ITSM platforms; familiarity with OT/IoT security frameworks (e.g., NIST SP 800-82).
• Ability to navigate enterprise IT governance environments where OT/BMS intersects with corporate IT security policy.

Soft Skills

• Independent, self-managing; translates technical findings into actionable items for non-technical stakeholders.
• Vendor-neutral and collaborative when working alongside multiple integrators, contractors, and managed service providers.

Preferred Qualifications:
