This role will support a large, complex industrial network and requires someone who can step into an existing environment, quickly understand the architecture, and contribute immediately with minimal ramp‑up.

• Work directly in production environments to validate, test, and implement solutions

• Experience supporting networks with:

  • Private LTE or Private 5G networks
  • Industrial networking use cases
• Familiarity working alongside:
  • OT engineers
  • Control systems teams
  • Plant operations
• Cisco certifications (CCNP, CCIE‑track) are a plus, but practical experience is valued more than credentials

Work Environment

• Onsite role in a steel manufacturing facility
• Must be comfortable:
  • Walking the plant floor
  • Climbing stairs
  • Working in hot and cold temperatures
• This role requires physical presence—remote‑only candidates will not be considered

Soft Skills & Cultural Fit (Critical)

• Self‑driven and proactive

• Comfortable navigating IT vs. OT dynamics
• Thick‑skinned and professional under pressure
• Able to work through conflict without taking things personally
