Specialist OT Engineer

Location: Brisbane, Queensland, Australia; Cremorne, Victoria, Australia; Sydney, New South Wales, Australia

Department: Operations

As a Specialist OT Engineer, you’ll be joining the IT & Security team responsible for maintaining High System Integrity Protection Scheme (SIPS) Performance at Waratah Super Battery; the most powerful BESS globally. In addition, the team recently achieved commercial operation date (COD) alongside the first full month of operational reporting for Akaysha’s Ulinda Park BESS.  

Building on this momentum, the role will focus on establishing and sustaining stable, reliable day-to-day OT system operations across multiple live sites. You will play a key role in supporting BAU activities, maintaining system integrity, and ensuring OT environments operate safely and predictably over time. 

Each site presents unique technical and operational considerations, offering the opportunity to deepen your experience in supporting the reliability, performance, and security of operational technology systems. This includes hands on involvement with SCADA servers and HMIs, as well as PCS, BMS, and EMS subsystems, throughout the operations and maintenance phase of largescale energy assets.  

Your expertise will be critical in enabling stable, visible and secure OT environments across Akaysha’s portfolio of assets with your work making a tangible impact as you: 

• Manage and maintain OT infrastructure—including SCADA, HMIs, BESS, gateways, and historians—while overseeing configuration, documentation, system health, automation, and lifecycle planning. 
  
  
• Support secure, governed OT–cloud integration (Azure/AWS) with accurate, high‑quality data flows for real‑time analytics and AI‑driven maintenance 
  
  
• Apply OT cybersecurity and compliance practices across AESCSF/IEC‑62443, hardening, secure access, monitoring, vulnerability management, asset control, backups, and SOCI requirements. 
  
  
• Maintain and troubleshoot OT system performance and communications across SCADA, RTUs, historians, and BESS subsystems while resolving incidents, supporting on‑call operations, and improving OT architectures and practices. 
  
  
• Coordinate OT vendor support, technical reviews, compliance, lifecycle planning, Tier 2/3 assistance, and commissioning activities while reviewing documentation and deliverables. 

Travel to AU sites once every 2-3 months or when needed, is a requirement of this position. The role can be based at Akaysha’s Melbourne (HQ), Sydney or Brisbane office with the option to work in a hybrid capacity – spending time in the office, and at home. 

Making an impact in this role will rely on proven expertise in the following areas:   

• Industrial Control Systems (ICS) & SCADA 
  Expertise in configuring and optimising ICS environments, including SCADA, HMIs, PLCs, RTUs, and IEDs for real‑time operations.
  
  
• Industrial Communication Protocols 
  Skilled in applying and interpreting industrial protocols - Modbus, DNP3, IEC 61850, and OPC/OPC‑UA—to ensure reliable device and system communication. 
  
  
• OT Cybersecurity 
  Proficient in applying OT security frameworks (AESCSF, IEC 62443) to guide hardening, segmentation, and secure system architecture. 
  
  
• Troubleshooting & Systems Diagnostics 
  Skilled in diagnosing faults across OT networks, control systems, data pipelines, and BESS subsystems using structured problem‑solving and root‑cause methods. 
  
  
• Cloud‑Integrated OT Systems 
  Knowledge of OT–cloud integration patterns, including telemetry pipelines, secure connectivity, and cloud‑based monitoring and analytics. 
  
  
• Vendor & Contractor Coordination 
  Experienced in coordinating technical validation and lifecycle activities with OEMs, service providers, and contractors across reviews and assessments. 
  
  
• Technical Documentation 
  Proficient in producing clear, accurate technical documentation, including diagrams, procedures, system records, and operational artefacts.
