MARA is seeking a Senior Power Systems Automation Engineer to design, implement, commission, and maintain power automation and SCADA systems across our data center, mining, generation, and utility-interconnected sites. These environments include large-scale electrical infrastructure such as substations, switchgear, meters, protective relays, RTACs, PLCs, generator controls, communication gateways, and energy management integrations. In this role, you will assess site requirements, define the appropriate control and monitoring architecture, evaluate and select hardware, coordinate installation, configure field communications, and commission reliable systems in production environments. You will also configure communication flows between site equipment, utilities, generation assets, third-party operators, and MARA’s internal energy management and operations platforms. The ideal candidate has a strong electrical engineering foundation, hands-on experience with power generation or utility-scale electrical systems, and practical expertise implementing SCADA, automation, telemetry, and industrial communication solutions in the field. This role requires someone who can move comfortably between engineering design, vendor coordination, site implementation, commissioning, troubleshooting, documentation, and long-term operational support.
ESSENTIAL DUTIES AND RESPONSIBILITIES:
Site Assessment & Solution DesignAssess data center, mining, generation, and utility interconnection requirements to determine appropriate SCADA, automation, telemetry, and control solutions. Design site-level power automation architectures for monitoring, control, dispatch, curtailment, generation coordination, alarm management, and operational visibility. Develop designs that account for site electrical topology, utility requirements, generation assets, substations, switchgear, meters, relays, RTACs, PLCs, communication networks, and operator workflows. Define device lists, point lists, control narratives, communication paths, failure modes, integration requirements, and commissioning criteria. Evaluate tradeoffs across safety, reliability, maintainability, cost, vendor support, cybersecurity, field complexity, and long-term operability. Collaborate with systems engineers, solution architects, electrical engineers, software engineers, and operations teams to align site designs with broader energy management and operational goals.
Power Automation & SCADA Implementation:
Design, configure, deploy, and maintain SCADA and power automation systems for site electrical infrastructure.
Evaluate and select hardware such as RTACs, RTUs, PLCs, protective relays, meters, gateways, network devices, HMIs, and related field equipment.
Configure and integrate intelligent electronic devices, including relays, meters, breakers, switchgear controls, generator controllers, and other site electrical assets.
Develop and maintain point databases, tag mappings, alarm definitions, control logic, device configurations, and telemetry models.
Coordinate with vendors, contractors, electricians, controls technicians, and site teams to support installation, checkout, and field implementation.
Ensure implemented systems are practical, supportable, and appropriate for real-world operating conditions at large electrical sites.
Communication & EMS Integration:
Configure reliable communication flows between site equipment, utility systems, generation assets, third-party operators, and internal energy management platforms.
Implement and maintain industrial communication protocols such as Modbus TCP/RTU, DNP3, IEC 61850, OPC UA, MQTT, or similar technologies.
Configure Modbus servers, protocol gateways, and data interfaces that expose validated site telemetry and control points to internal systems.
Ensure telemetry, control commands, alarms, and status points are mapped, validated, documented, and supportable.
Design communication architectures that support secure data exchange, resilient operations, observability, and maintainability.
Troubleshoot protocol, network, device communication, data quality, latency, and integration issues across field and enterprise systems.
Commissioning, Reliability & Field Support:
Plan and execute factory acceptance testing, site acceptance testing, commissioning, and validation for new or upgraded power automation systems.
Verify telemetry, control paths, alarms, interlocks, failover behavior, command permissions, operating procedures, and emergency states before production handoff.
Support ongoing maintenance, upgrades, troubleshooting, and root-cause analysis for SCADA and power control systems.
Develop redundancy, fail-safe, backup, and recovery approaches for critical control and monitoring functions.
Partner with operations teams to ensure systems are safe, reliable, understandable, and aligned with site operating requirements.
Travel to data center, mining, generation, substation, and utility-interconnected sites as needed for assessment, installation coordination, commissioning, troubleshooting, and maintenance.
Documentation & Cross Functional Execution:
Create and maintain documentation for SCADA architectures, communication diagrams, device configurations, point mappings, control narratives, test plans, runbooks, and maintenance procedures.
Communicate technical decisions, risks, dependencies, field constraints, and implementation status clearly to engineering and operational stakeholders.
Provide technical guidance to operators, technicians, and engineering partners on system behavior, troubleshooting, and operational best practices.
Review vendor proposals, drawings, submittals, and implementation plans for technical fit, reliability, maintainability, and integration impact.
Help establish repeatable standards for power automation, SCADA integration, commissioning, telemetry validation, and site handoff.
