⚠️ Common Mistakes to Avoid

  • Submitting a generic application without referencing rail systems or AECOM’s specific projects.
  • Overlooking the safety leadership aspect—this role is for an established safety professional, not just a systems engineer.
  • Failing to demonstrate hands-on experience with DOORS or ComplyPro; vague mentions won’t suffice.
