- Technical Stack: Proficiency in at least one modern programming language (Python, Go, or similar), familiarity with cloud platforms (preferably GCP), containerization, and CI/CD practices
- Adaptability: Strong track record of working across shifting priorities and unfamiliar domains, comfortable learning quickly and context-switching between operational, integration, and security tasks
