  • Proven ability to lead and coordinate multidisciplinary engineering teams.
  • Excellent communication skills, both written and verbal.
  • Ability to balance technical rigor with project schedule and cost constraints.
  • Client-focused, proactive, and solution-oriented.

Preferred Experience:
