Nature of work no kras
Vague JD — no KRAs present to derive a specific nature of work.
Tech stack maturity
Modern Cloud Native
Backend development today is typically built around cloud-hosted services, containers, CI/CD, and distributed systems, but AI is usually only an optional integration rather than the core of the role.
