The Opportunity

Our Grid Automation business unit offers a comprehensive portfolio of solutions, encompassing substation automation, communication networks, grid automation services, grid edge solutions, and enterprise software solutions. These offerings address all key segments associated with the energy system, including generation, transmission, distribution, industries, transportation, and infrastructure sectors.

How You'll Make an Impact

  • Master's degree in Electrical Engineering (Power Systems).
  • Deep knowledge of power system protection, with an emphasis on busbar protection (fault studies, CT behavior including CT saturation, settings coordination, selectivity).
  • Hands-on experience configuring, testing, and validating protection IEDs using engineering tools and IEC 61850 engineering artifacts (ICD/CID/SCL).
  • Proficiency in C++ and ADA for protection/embedded application development, with a strong debugging, code review, and unit/integration testing discipline.
  • Practical experience with Adwin Pro test systems and OMICRON-based automated testing (test plan design, automation, and regression execution).
  • Proven track record of delivering complex features to release milestones—from architecture to implementation and integration.
  • Experience in triaging and resolving product feedback end-to-end, including root cause analysis, implementation proposals, and validation.
  • Direct customer support and interaction to elicit true requirements and propose solutions that minimize unnecessary firmware changes where feasible.
  • Collaboration with support, Product Management, and cross-functional teams; creation of clear operational documentation for engineering and test teams.
  • Working knowledge of Azure DevOps (Boards/Repos/Pipelines) or equivalent for backlog, CI/CD, branching, and version control.

Your Background

  • Familiarity with IEC standards for protection systems (IEC 61850, IEC 60255); experience analyzing and closing conformance test findings.
  • Test automation at scale, data-driven validation, and integration with automated test system toolchains.
  • Strong systems engineering mindset across the product lifecycle; ability to produce concise implementation proposals for complex features.
  • Experience crafting customer-specific adaptations to reduce rework and future changes.
  • Scripting to accelerate workflows and test harnesses such as Ruby; comfort in learning new languages and tools quickly.
  • Effective communication with distributed teams; ability to take ownership of ambiguous, cross-domain tasks outside the comfort zone.
  • Support for type tests and factory/acceptance testing; ability to produce step-by-step operation guides for stable system operation.
