The role

You will keep the systems that connect the plant floor to the enterprise running — historians, networks, interfaces and the boundary between IT and OT.

What you will do

  • Support and maintain manufacturing IT/OT infrastructure and interfaces
  • Manage historian, MES and control system integrations
  • Maintain OT network segmentation, patching and backup regimes
  • Support 24/7 manufacturing including on-call rotation
  • Partner with automation and security on plant system changes

What success looks like at 12 months

Plant system availability is high and measured, integrations are documented, and OT changes go through control without disrupting production.

What we require

  • Experience with industrial IT, OT networks or manufacturing systems
  • Networking fundamentals and troubleshooting ability
  • Understanding of change control in a regulated environment
  • Availability for on-call support of a 24/7 site

What we would like, but will teach you

  • Historian or MES experience
  • OT security experience
  • Military communications or network background

If you meet the required list, apply. We cap the preferred list at four items on purpose, and we would rather read an application from someone who is 70% there and hungry.

Military & veteran candidates

Military communications and network backgrounds transfer directly.
