  • Support project-specific modeling needs by adapting or developing models as required

Internal Collaboration & Thought Leadership

  • Work closely with software engineering teams to integrate modeling requirements into product development
  • Contribute to QA/QC processes for models and modeling workflows

    • Familiarity with international grid codes (e.g., Australia, Germany, Europe)
    • Understanding of Agile or modern software development workflows
    • Exposure to both regulated and deregulated electricity markets.
