1755 - Azure Network Engineer

Sigma Defense is seeking an Azure Network Engineer with deep Microsoft Azure expertise, rather than a general cloud administrator who has occasionally configured networking.

I candidati sono invitati a leggere attentamente tutti gli elementi di questo annuncio. La preghiamo di inviare la sua candidatura tempestivamente.

This individual should be comfortable taking ownership of complex connectivity problems involving multiple networks, security boundaries, routing paths, firewalls, and cloud environments. The ideal candidate understands how traffic should move through an Azure architecture and can design secure solutions that provide required connectivity without unnecessarily expanding the network attack surface.

Equal Opportunity Employer/Veterans/Disabled: Sigma Defense Systems is an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, or protected veteran status and will not be discriminated against on the basis of disability.
