• Hands-on with Kubernetes and containerization (Docker).
• Good grasp of system design, API design, and network protocols.

Frontend proficiency:

• Comfortable with HTML/CSS/SCSS (BEM/SMACSS or similar methodologies).

Engineering foundations:

• Degree in Computer Science or related field (or equivalent experience).
• Excellent knowledge of CS fundamentals, database theory, and code-testing practices.
