Senior QA Engineer - SCADA, WAMS & Grid Integration

JOB TITLE: Senior QA Engineer - SCADA, WAMS & Grid Integration
REPORTS TO: QA Lead/Programme Delivery Manager
LOCATION: Warwick or Wokingham (2 days a week onsite)

Role Overview

We are seeking an experienced Test Quality Assurance Specialist to join our mission-critical Energy Management Systems (EMS) programme. You will be responsible for assuring the quality of our next-generation GridOS WAMS and GE Reliance AEMS platforms.

This is not a purely execution-focused role. You will act as the Voice of Quality, governing test strategies, leading defect triage, and ensuring that complex integrations involving IEC protocols, Middleware, and APIs meet the stringent reliability standards required for Real Time power network operations.

Key Responsibilities

1. Test Strategy & Quality Governance (The "Assurance" Element)

• Define, review, and enforce the overall Test Strategy, Test Plans, and Entry/Exit Criteria across multiple workstreams.

• Act as the primary QA representative in Agile ceremonies (PI Planning, Sprint Reviews), providing quality dashboards and risk assessments to Product Owners and Delivery Managers.

• Lead defect triage meetings, driving the prioritisation and resolution of blocking issues.

• Review test evidence and execution reports produced by other testers to ensure maximum coverage and adherence to central testing standards.

• Identify process gaps and implement continuous improvements within the QA life cycle.

2. SCADA, WAMS & Protocol Testing

• Validate the functionality, performance, and reliability of GE Reliance AEMS and GridOS WAMS systems.

• Execute and oversee end-to-end testing of telemetry data flows, ensuring accurate data acquisition and network model visualisation.

• Conduct rigorous conformance and interoperability testing for IEC 101 (Telemetry) and IEC 61850 (Substation Automation) protocols.

• Oversee Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) for substation integration points.

3. Integration & Middleware Validation

• Design and execute test scenarios for data exchange between the SCADA environment and external enterprise systems via Oracle MFT (Managed File Transfer) and Mulesoft APIs.

• Validate error handling, data transformation logic, and latency for all integration touchpoints.

4. Defect Management & Reporting

• Manage the end-to-end defect life cycle using JIRA/XRAY, ensuring all issues are clearly documented, reproducible, and tracked to closure.

• Produce detailed test summary reports and quality metrics for senior stakeholders.
