About Mercari

Circulate all forms of value to unleash the potential in all people

"What can I do to help society thrive with the finite resources we have?" The Mercari marketplace app was born in 2013 out of this thought by our founder Shintaro Yamada as he traveled the world. We believe that by circulating all forms of value, not just physical things and money, we can create opportunities for anyone to realize their dreams and contribute to society and the people around them. Mercari aims to use technology to connect people all over the world and create a world where anyone can unleash their potential. For more information about Mercari Group’s mission, seeMercari’s Culture Doc



Organization/Team Mission

Mercari's data analytics environment is used by around 1,200 employees per month (approximately 60% of our entire workforce). With offerings like "Socrates," our LLM-based analytics application, our data infrastructure is already one of the most advanced in Japan.

However, the needs for data utilization and the surrounding technologies are changing rapidly. This creates new challenges daily, as our existing approaches find it difficult to meet the growing demand for enhancements.

To adapt to these changes, we are actively leading new approaches, such as automating the data modeling lifecycle. Our goal is to build an environment where data products can significantly accelerate product development. By leveraging AI/LLM to solve these structural challenges, we will streamline the data experience for all employees and maximize the value we provide to our customers.

Seehere for more information about our mission and values.



Work Responsibilities

This role will lead the evolution of Mercari's data analytics environment to its next phase. You will be responsible for building a highly automated and intelligent data ecosystem, enabling all employees to derive value from data with the highest levels of efficiency and trust.

Responsibilities:

  • Continuously improve and add value to existing data products used company-wide, such as Socrates, Basic Tables, Semantic Layer, and various dashboards.
  • Utilize technologies like AI/LLM to build a mechanism that automates the entire data modeling lifecycle, from identifying opportunities for optimization through to design and implementation.
  • Define and implement a semantic layer to act as a Single Source of Truth (SSoT) for both humans and AI, thereby reducing the risk of decisions based on incorrect data.
  • Develop a business metadata foundation to convert department-siloed knowledge (such as marketing strategies) into a common, company-wide asset.
  • Collaborate with corporate functions (e.g., HR, Finance) to transform department-specific operational data into data products, thereby enhancing the cross-functional decision-making foundation.

Note: The scope of work is not fixed and will change flexibly according to the scale of challenges the team faces and technological progress.



Unique Challenges

  • Leading at the Forefront: Mercari is a leader in applying data and AI, exemplified by our LLM application, "Socrates." Because we are at the forefront, you will be tackling challenges that others have yet to encounter.
  • Beyond Traditional Engineering: This is not a conventional data engineering role focused on simply preparing data. You will step into an unprecedented field, tasked with unleashing the synergy between data, AI, and human intelligence.
  • Solving Next-Generation Problems: The success of our advanced tools has introduced new, complex problems, such as managing query performance at scale and maintaining data trust in an automated environment. Your challenge will be to lead the way by:
    • Building an autonomous system where AI continuously drives the data modeling lifecycle.
    • Architecting a semantic layer from the ground up to serve as a single, reliable source of truth for both people and algorithms.

Your work will directly enhance the quality of company-wide decision-making and maximize the value we deliver to our customers. This is a chance to define the future of data-driven organizations.



Qualifications

  • Required Experience/Skills
    • Resonates with the mission and values of the Mercari Group and its individual companies
    • Experience collaborating with stakeholders who use data and leading initiatives to solve business challenges
    • Strong interest in, or hands-on experience with, improving data platforms and streamlining operations using AI/LLM
    • Experience designing, building, and managing data marts in a data warehouse (e.g., BigQuery) using SQL
    • Experience designing and implementing data governance and semantic layers using BI tools such as Looker

  • Preferred Experience/Skills
    • Proactively keeps up with fast-changing technology trends, especially in AI/LLM, and applies them effectively in day-to-day work
    • Experience managing projects, particularly in gathering and prioritizing requirements from multiple stakeholders and defining project scope

    • Japanese: B2 (Must)
    • English:  B2
