Senior Security Engineer

Single Point Global - Austin, TX


Sr. Security Engineer

Security administration is a hands-on role that requires a high level of technical expertise. The person in this position is responsible for a broad range of tasks, including the day-to-day administration of information security tools and devices, as well as first-level and second-level support for security information and event management (SIEM), and may include significant responsibilities for the security administration of a wide variety of IT systems across the enterprise.

Additionally, as legal and regulatory compliance drivers continue to grow in impact and importance, many of the security Engineer's tasks may also be part of an audit support function.

The individual in this position interacts closely with product vendors and service providers, with personnel from various IT departments — including the application development, operations and network, and privacy teams — and with business departments. In-depth knowledge of [Company Name]'s operating systems and security applications, as well as a working knowledge of basic network protocols and tools, is also required.
