We're a fast-growing freight brokerage with a mission bigger than logistics. We’re building a business on excellence, integrity, and purpose — putting service first in all that we do.

• Execution Partner: Step in wherever needed — from vendor coordination to special projects — to keep momentum strong.

What We’re Looking For

• Experience in executive operations, business management, or a related field (freight/logistics experience is a plus, but not required).
• Strong project management and organizational skills — you thrive on structure, clarity, and follow-through.
• Excellent written and verbal communication.
• Tech-savvy and comfortable learning new tools quickly.
• A balance of strategic thinking (anticipating needs, seeing the big picture) and tactical execution (rolling up your sleeves to get things done).
• Someone who is dependable, resourceful, and thrives in a fast-paced, growing startup environment.
• Someone who speaks both Ukrainian and English is a preference! 

Why Join Us?

• Be part of a values-driven company that believes in service first.
• Work closely with the CEO and leadership team, gaining unique exposure to the inner workings of a scaling logistics company.
• Help shape systems, processes, and culture in the early stages of growth.
