[Hiring] Senior Engineer @Hunt St

Role Description

We're looking for an experienced Senior Engineer (Level 3) to become the senior technical escalation point for complex infrastructure, cloud, networking, and cybersecurity issues while supporting the successful delivery of client projects.

The successful candidate will thrive in a fast-paced MSP environment, demonstrate exceptional technical depth across Microsoft technologies, networking, cloud platforms, and security, and be confident making independent technical decisions while supporting clients across multiple time zones.

  • Translate technical concepts into practical business outcomes.
  • Collaborate closely with Project Managers, Service Delivery Managers, and Account Managers to ensure excellent client outcomes.
