Infrastructure as Code awareness: Terraform/HCL basics.
Cloud platform fundamentals: AWS (compute, managed databases, storage, networking, and secrets management); familiarity with Azure or GCP is a plus.
Code Quality

Soft Skills
Team-first mindset - shares knowledge proactively, unblocks colleagues, and treats code review as a teaching opportunity rather than gatekeeping.
Active ownership - raises concerns early, follows through on commitments, and closes the loop without being reminded.
Honesty and transparency - surfaces bad news quickly, acknowledges mistakes, and documents lessons learned so the team does not repeat them.
Hard-working and dependable - comfortable sustaining high-quality output under delivery pressure without cutting corners on security, testing, or maintainability.
