• Participating in daily dispatch operations: selecting trucks for orders, assigning field staff teams to jobs, and making sure each order has the right crew and vehicle.
• Distributing field staff teams across orders based on schedule, location, job complexity, availability, and operational needs.
• Monitoring whether orders are properly covered: team assigned, truck assigned, notes updated, and all key details checked.
• Supporting dispatchers during busy hours, complex jobs, delays, changes, or unexpected situations.
• Monitoring task completion and quality of service.
• Adapting and training new dispatchers: giving instructions, explaining processes, providing feedback, and supporting their growth.
• Participating in creating and documenting processes that are missing or need improvement.
• Maintaining constant communication with dispatchers and other departments: Sales, Customer Support, HR, drivers, and field staff.
• Resolving non-standard situations: vehicle breakdowns, delays, staffing shortages, schedule changes, client issues, or team replacements.
• Updating CRM and reports: tracking orders, comments, payments, fines, tolls, vehicle maintenance alerts, and other operational details.
• Suggesting process improvements to increase speed, structure, and quality of operations.

This role is a great fit if you:

• Can combine leadership with hands-on operational work.
• Can manage multiple tasks and keep the team organized.
• Stay calm under pressure and think clearly.
• Take responsibility for team results, not just your own tasks.
• Understand that dispatching is about speed, accuracy, communication, and attention to detail.
• Can delegate tasks effectively and provide constructive feedback.
• Support new team members and share knowledge practically.
• Can resolve conflicts without escalation, balancing client and company interests.
• Are ready to be actively involved in daily operations, not only supervise from the side.
   

If you have recognised yourself and are ready for a new challenge, we are waiting just for you!

• Співпрацювати із зовнішніми експертами та консультантами, перетворюючи їхні рекомендації на практичні рішення для щоденної роботи команд.

Досвід, який стане твоєю перевагою:

• 2–4 роки досвіду на позиції координатора, менеджера проєктів або операційного спеціаліста з роботою між кількома командами;
• Відмінні організаційні навички та здатність доводити справи до завершення — ви закриваєте всі відкриті питання;
• Впевнене володіння Jira та Confluence, комфортна робота з налаштуванням workflow і дашбордів;
• Комфортне використання AI-інструментів у щоденній роботі;
• Практичний досвід роботи щонайменше з одним no-code інструментом автоматизації.

Ми цінуємо:

• Допитливість: ви ставите уточнювальні запитання, щоб краще зрозуміти проблему, процес або робочий потік;
• Мислення людини, яка доводить справи до кінця: ви завершуєте розпочате, а незакриті питання вас турбують;
• Мислення людини, яка підтримує порядок: ви підтримуєте організованість не час від часу, а постійно. Документація, фолоу-апи та невеликі покращення не залишаються поза увагою;
• Увага до деталей: ви помічаєте невідповідності, відсутність відповідальних осіб і блокери, які інші можуть не побачити;
• Готовність ставити під сумнів: ви висловлюєте свою думку, якщо щось не має сенсу, роблячи це конструктивно та з повагою.

Наші клієнти пропонують конкурентні переваги для підтримки вашого професійного та особистого зростання, зокрема:

• Орієнтація на здоров’я та добробут;
• Медичне страхування;
