About the Team
At Trendyol Core Commerce, we build innovative, data-driven strategies that power sustainable growth and global expansion.
From seller experience to new market launches, we turn insights into action—fast. Our cross-functional teams shape the future of commerce with bold ideas, real-time impact, and a deep sense of ownership. In a fast-paced, collaborative environment, we grow together — as individuals and as a team.

We are seeking a strategic and customer-driven Marketplace Seller Support Specialist to guide our regional operations across the CEE market. In this highly visible role, you will bridge the gap between our third-party support vendors and internal cross-functional teams. By evaluating service quality from the seller's perspective, you will ensure our vendor teams deliver an exceptional support experience while maintaining operational efficiency. This is a unique opportunity to shape international vendor operations from end to end and serve as the primary voice of our sellers in a fast-paced, growing environment.

Responsibilities

  • Manage the day‑to‑day operations of outsourced agent teams handling marketplace seller requests.
  • Coordinate with planning teams to facilitate capacity planning, staffing adjustments, and ongoing training schedules.
  • Monitor team performance against SLAs and KPIs, designing supportive, actionable plans to elevate service quality.
  • Collaborate closely with Quality and Training departments to identify capability gaps and implement targeted development programs.
  • Lead incident response for escalations, seamlessly coordinating with legal, risk, and central operations teams during seller crises.
  • Facilitate a continuous feedback loop from vendors to central business teams to improve tools, policies, and cross-functional processes.
  • Initiate and manage development projects focused on streamlining agent workflows and adapting to emerging seller needs.

Expected Qualifications

  • University degree, preferably in Engineering, Economics, or Management.
  • Experience in digital experience, project management, process improvement, or vendor-operations management; e-commerce background is a plus.
  • Excellent analytical and problem-solving skills, with the ability to translate operational insights into practical business solutions.
  • Strong stakeholder management and cross-functional collaboration abilities to effectively align external vendors with internal teams.
  • Capable of managing crises and complex escalations calmly while maintaining a customer-first mindset.
  • Adaptable and highly responsible, comfortable working iteratively to optimize processes and balance operational costs with seller satisfaction.
  • Excellent written and verbal communication skills in Romanian (native level) and English.

What We Offer
- Hybrid working model with flexibility: a schedule that helps you find the right balance between flexibility and team bonding, including work-from-abroad opportunities and a summer working model.
- Personalised training allowance and learning opportunities: Use your annual budget for any training or conference of your choice, explore our Learning Management System (LMS) anytime, and join in-person learning sessions offered throughout the year.
- Responsibility from day one: Take full ownership from the start in a culture where every voice is heard and valued.
- A diverse, international team: Collaborate with global peers across our offices in Berlin, Amsterdam, Dubai, and beyond, in a startup-spirited and collaborative environment.
- Opportunities to grow with the best: Tackle meaningful challenges, develop through hands-on experience, and grow with the support of expert guidance and global mentoring.
- Meaningful connections beyond tasks: Be part of team rituals, events, and social activities that help us stay connected and inspired.
