Jobtailor; Hyderabad; On-site; INR 1,200,000 - 2,100,000; Full time

Job summary

Jobtailor is seeking an experienced embedded software test engineer to define the V&V strategy for IEC 61850 protocol stacks and to deploy scalable test automation across SCL configurations and SV/GOOSE messaging. You will lead the full validation of the IEC 61850 stack and integrate automated suites into CI/CD pipelines.

The role requires 5+ years in embedded testing, expertise in MMS/GOOSE/SV, and hands-on experience with HIL testing using RTDS/OPAL-RT platforms.

Qualifications

• Bachelor’s or Master’s Degree in Electrical/Electronics, Power Systems, or Computer Science.
• Minimum 5+ years of experience in embedded software testing with IEC 61850 (Data models, SCL/CID files, GOOSE, SV, MMS) and IEEE 1588/PTP synchronization.
• Experience with CI/CD integration for automated regression testing and exposure to IEC 62443 cybersecurity standards in mission-critical environments.
• Strong understanding of power system protection, SCADA architectures, and experience with real-time power system simulators for HIL testing.
• Proven experience with GE Vernova Grid Automation products or comparable advanced protection relay platforms and their configuration software.
• Proven ability to design/deploy automation frameworks using Playwright, Cypress, or Python-based suites for protocol testing.
• Extensive experience validating protection relay performance in a digital process bus architecture, SV/GOOSE-based tripping schemes.

Responsibilities

• Define and own the V&V strategy for IEC 61850 protocol stacks, SV integration, and substation features.
• Design and deploy scalable, high-efficiency Test Automation Frameworks for SCL configurations and MMS/GOOSE/SV messaging.
• Lead validation of the full IEC 61850 stack with MMS/GOOSE/SV compliance.
• Oversee project estimation, planning, and execution for NPI and LCS projects with CI/CD integration.
• Develop custom automation tools (Playwright, Cypress, Python) and utilize HIL platforms (RTDS/OPAL-RT) for validation.
• Collaborate with global systems engineering teams to translate substation requirements into automated validation suites.

Job description

Responsibilities

• Define and own the V&V strategy for IEC 61850 protocol stacks, Sampled Values integration, and digital substation communication features within the Gridbeats ICT/SCT & APS product lines.
• Design and deploy scalable, high-efficiency Test Automation Frameworks to validate SCL configurations, MMS/GOOSE/SV messaging, and perform network stress/latency testing.
• Serve as the primary technical authority for IEC 61850 (Ed 1/2) implementation. Lead the validation of the full communication stack, ensuring strict adherence to MMS, GOOSE, and Sampled Values (SV) messaging requirements.
• Lead project estimation, planning, and execution for NPI and LCS projects. Integrate automated test suites into CI/CD pipelines (e.g., Jenkins/GitLab) to enable continuous, shift-left validation.
• Lead the development of custom automation tools (Playwright, Cyprus, or custom Python-based suites) and utilize Hardware-in-the-Loop (HIL) simulation platforms (e.g., RTDS, OPAL-RT) to verify protection relay behaviour under transient and steady-state conditions.
• Partner with global systems engineering teams to translate complex substation requirements into robust, automated, and secure validation suites.

Requirements

• Bachelor’s or Master’s Degree in Electrical/Electronics, Power Systems, or Computer Science.
• Minimum 5+ years of experience in embedded software testing with deep expertise in IEC 61850 (Data models, SCL/CID files, GOOSE, SV, MMS) and IEEE 1588/PTP synchronization.
• Experience with CI/CD integration for automated regression testing and exposure to cybersecurity standards (IEC 62443) in mission-critical environments.
• Strong understanding of power system protection, SCADA architectures, and experience with real-time power system simulators for HIL testing.
• Proven experience with GE Vernova Grid Automation products or comparable advanced protection relay platforms and their associated configuration software.
• Proven experience with IEC-61850 configuration tools like IED & System configuration tools.
• Proven ability to design/deploy automation frameworks using tools like Playwright, Cyprus, or custom Python-based suites for protocol testing.
• Extensive experience validating protection relay performance in a digital process bus architecture, replacing conventional copper wiring with SV (IEC 61850-9-2) and GOOSE-based tripping schemes.
• Proven ability to execute complex utility fault scenarios (e.g., evolving faults, high-impedance faults, power swings) using secondary injection kits (e.g., Omicron, Megger) integrated with real-time digital simulators.
• Rigorous verification of protection function response times (e.g., differential, distance, and overcurrent) under varying network conditions, specifically measuring the impact of network congestion on GOOSE message delivery and SV stream stability.
• Proficiency in setting up "system-level" test environments to verify the seamless exchange of data between IEDs, Merging Units, and station controllers from different manufacturers.
• Experience preparing for and executing formal Type Testing and IEC 61850 Conformance Testing, ensuring that all protection algorithms meet defined accuracy and speed requirements under both static and dynamic network environments.

Core Competencies

Demonstrates expertise in IEC 61850 protocol stacks, including GOOSE and SV messaging, and the ability to design and implement robust test automation frameworks for power systems. Proficient in CI/CD integration and validation of protection relay performance in digital substation environments.
