The posting
We are looking for an experienced Senior IT Network Engineer to own and support Spire’s corporate and back-office network environment.
Reporting to the Global IT Director, this is a hands-on role with primary responsibility for the design, implementation, operation, reliability, and lifecycle management of the corporate network.

- Develop and maintain scripts, infrastructure-as-code, and automation used to deploy, configure, monitor, or manage corporate network services.
- Implement and maintain monitoring and alerting to identify network availability, reliability, capacity, and performance issues.
- Plan and execute network hardware, software, certificate, circuit, and service lifecycle activities.
- Support office openings, moves, expansions, consolidations, closures, and network infrastructure changes in partnership with End User Technology, Facilities, carriers, and vendors.
- Manage or coordinate ISP, carrier, circuit, and network-vendor relationships where required.
- Follow disciplined change-management practices, including planning, peer review, testing, documentation, rollback planning, and post-change validation.
