OT PLATFORM & SCADA SOFTWARE DEVELOPER

PRIMARY OBJECTIVES Establish a verified inventory and capability map of the existing OT application portfolio, interfaces, data flows, duplication, dependencies and lifecycle constraints. Define a vendor-neutral target architecture for common OT data, integration, visualization, alarm/event, historian, reporting, identity, audit and workflow services. Reduce unnecessary standalone applications and duplicated functions through a controlled application-rationalization and migration roadmap. Create reusable software components, connectors and engineering standards that simplify future integration and reduce manual support effort. Coordinate with internal stakeholders and related suppliers to identify practical, secure and commercially sustainable implementation options. KEY RESPONSIBILITIES OT Platform Unification and Application Rationalization Assess DSM, DFR, PQ, SCADA, historian, alarm, reporting, engineering and other OT applications across control centers and substations. Document business and operational capabilities, system owners, interfaces, data sources, users, licensing, infrastructure, cybersecurity posture and support arrangements. Identify overlapping functions, isolated data stores, obsolete components, integration gaps, technical debt and opportunities for shared services. Define target-state principles, common data models, integration patterns, platform boundaries, transition states and a prioritized consolidation roadmap. Ensure the target design remains modular, interoperable and maintainable and does not create unnecessary product lock-in. Software Development and Systems Integration Design and develop middleware, services, APIs, adapters, data-normalization components, event processing, validation tools and automation scripts for OT integration. Integrate operational data through open interfaces and relevant power-system protocols, including IEC 60870-5-101/104, IEC 61850, DNP3, Modbus, OPC UA/DA and ICCP/TASE.2. Implement common functions for dashboards, alarms/events, trends, historian access, disturbance records, PQ information, reporting, workflow, identity and audit where technically appropriate. Apply structured software engineering practices covering source control, code review, automated testing, release management, configuration management and technical documentation. Supplier and Stakeholder Coordination Lead technical workshops with operations, protection, power quality, telecommunications, cybersecurity, infrastructure, database and engineering stakeholders. Coordinate with existing and prospective suppliers to confirm interface availability, data ownership, performance limitations, cybersecurity controls, licensing impacts and migration dependencies. Prepare technical requirements, interface control documents, evaluation criteria, clarifications and proof-of-concept scopes for solution selection. Evaluate options objectively against operational reliability, interoperability, maintainability, cybersecurity, scalability, lifecycle effort and total cost implications. Testing, Migration and Operational Support Prepare and execute unit, integration, performance, failover, recovery, cybersecurity, Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) test cases. Plan phased migration, coexistence, cutover, rollback and stabilization activities for live control-center environments. Support incident diagnosis and root-cause analysis across software, data, interfaces, servers, networks and third-party application boundaries. Maintain architecture decisions, interface mappings, configuration baselines, release notes, test evidence, as-built documents and support procedures. OT Cybersecurity and Governance Apply secure-by-design principles, network segmentation, least privilege, role-based access control, secure interfaces, audit logging, backup and disaster recovery. Support compliance with the utility's cybersecurity policies, IEC 62443 principles and applicable Saudi National Cybersecurity Authority OT requirements. Ensure changes follow approved architecture, change control, testing, release and operational-handover processes.

Desired Candidate Profile

The OT Platform & SCADA Software Developer will help the utility simplify and modernize its operational technology environment by consolidating fragmented applications into a secure, maintainable and vendor-neutral platform. The role will assess DSM, Digital Fault Recorder (DFR), Power Quality (PQ), SCADA, historian, alarm, reporting and related OT applications; define common platform services and interfaces; develop integration components; coordinate technical work with suppliers; and support phased migration without compromising control-center reliability or operational continuity.
