Core Responsibilities

Primary Functions

Perform on-site diagnostics and complex hardware repairs on a wide range of ATMs and peripherals (cash dispensers, recyclers, card readers, PIN pads, thermal printers), identifying root causes and executing repairs to restore full functionality while minimizing customer downtime.
Execute preventive maintenance (PM) programs according to manufacturer schedules and service-level agreements (SLAs), including cleaning, lubrication, firmware updates, component replacement, and functional verification to reduce future failures and extend device life.
Install and commission new ATM units and upgrades: rack and secure machines, install hardware modules, configure base software/firmware, validate peripheral connectivity, and perform first-run tests including cash dispenses and deposit acceptance when applicable.
Perform EMV chip reader removal and replacement, diagnose card reader failures, and test EMV transactions end-to-end to ensure chip and magnetic stripe transactions operate correctly and comply with industry standards.
Manage secure key injection and cryptographic key management tasks (e.g., DUKPT, Master/Session key procedures) using approved hardware security modules (HSMs) and follow strict chain‑of‑custody protocols and documentation requirements.
Troubleshoot and resolve network and communications problems impacting ATMs using TCP/IP diagnostics, VLAN/trunk verification, firewall/port checks, VPN troubleshooting, and coordination with network teams and ISPs to restore online services.
Replace and calibrate cash dispenser modules and recyclers, adjust cassettes, resolve cash jams, conduct note validation and counterfeit detection tests, and reconcile cash handling discrepancies per bank policy.
Maintain and service ATM safes and locking mechanisms, perform safe combination changes and key management under dual-control procedures, and document secure access events in accordance with banking security standards.
Apply software and firmware patches, perform OS-level updates for Windows Embedded / IoT or vendor OS, run vendor-supplied diagnostic suites, and escalate software bugs with detailed logs when issues require vendor engineering intervention.
Respond as the primary on-site representative for customer escalations, provide clear explanations of repairs and preventive recommendations to branch staff, and ensure a positive customer experience while protecting customer data and privacy.
Conduct parts replacement and inventory management: identify required spare parts during visits, update parts usage records, and coordinate replenishment to minimize MTTR (mean time to repair).
Perform ticket lifecycle management within the service management system: open accurate trouble tickets, update status and resolution notes, capture diagnostic logs and photos, and close tickets after verification with the customer.
Adhere to PCI-DSS, ADA, and corporate security and safety policies during all service activities—handle encryption devices and sensitive materials appropriately and complete required compliance documentation.
Execute emergency support and on-call rotations, attending to critical incidents outside normal business hours, triaging outages, and restoring critical cash access for impacted customers or branches quickly and professionally.
Conduct post-repair validation including end-to-end transaction tests, receipt printing verification, card retention checks, and capture transaction logs to confirm the machine is fully operational before leaving the site.
Liaise with vendors, manufacturers, and internal engineering teams for warranty claims, depot repairs, component RMA coordination, and to escalate complex technical issues requiring vendor engineering or remote patch releases.

Secondary Functions

Maintain detailed, organized service documentation including maintenance logs, photos of faults and repairs, incident reports, and regulatory compliance records to support audits and quality programs.
Provide informal on-the-job training and mentorship to junior technicians and contractors at job sites, sharing vendor-specific best practices, safety procedures, and troubleshooting techniques.
Support root cause analysis and continuous improvement initiatives by compiling failure trend data, suggesting part or firmware changes, and participating in post-incident reviews to reduce repeat failures.
Assist operations teams with site readiness checks prior to new deployments (power, network, environmental, ADA clearance), and coordinate site access scheduling with branch managers and security teams.
Participate in scheduled technical training sessions and vendor certification programs to maintain up-to-date knowledge of hardware families, software updates, and compliance requirements.
Support inventory and logistics by verifying parts shipments, performing basic warehouse checks, and coordinating the movement of refurbished or decommissioned units according to asset management policies.
