How You Will be Successful

In your first year, you will independently lead OT discovery and assessment work that clients trust, produce client-ready deliverables that move decisions forward, earn credibility with both plant-floor and executive stakeholders, strengthen the delivery team through coaching and review, and contribute reusable OT methods that improve how AHEAD delivers.

Why This Role Matters

OT consulting is not about applying enterprise IT controls unchanged to a plant floor. It takes technical depth, operational humility, and the ability to make progress without losing sight of safety, reliability, or recovery. If you have spent your career understanding how industrial environments work and want to help organizations make them more secure and resilient, this role puts that experience in front of the clients who need it.
