## Job description

Mercari is Your Marketplace. We make it super easy to sell (or buy) almost anything. We all have things we don’t use, never used or simply outgrew. But that stuff still has value. Mercari gives you the power to simply sell it, ship it, and earn some cash for it. Fashion to toys. Sporting goods to electronics. All the brands you know and love. Our mission is simple: to make selling easier than buying. And with 50M+ downloads in the U.S. and 350k+ new listings every day, we're just getting started.

As a Software Engineer, Data, you will be developing and enhancing our marketplace platform's data infrastructure. You will work with modern data technologies, build scalable data pipelines, and collaborate with cross-functional teams to deliver high-quality data solutions. This role emphasizes data engineering best practices, including governance, security, and compliance. In this role you will mentor and guide junior engineers, and help build strong engineering practices within the team.  You will leverage AI tools and technologies to enhance workflows and processes to improve efficiencies, and you will apply development tools, including AI assistance, to deliver quality code efficiently.

What you’ll be doing:

- Design, develop, and maintain scalable data pipelines using GCP services like Dataform, BigQuery, and Airflow
- Optimize data processing and storage, focusing on performance and cost efficiency
- Write comprehensive data quality tests to ensure data reliability
- Work closely with data teams to implement complex data models
- Develop reusable data components and shared libraries
- Mentor junior engineers and provide constructive feedback through code reviews
- Contribute to technical documentation and architectural decisions

What you’ll need:

Bachelor's degree in Computer Science, Data Science, Engineering, or a related field (or equivalent experience)

- 4+ years of experience in data engineering
- Experience with GCP data services (BigQuery, Dataform, Dataflow, Pub/Sub)
- Experience setting up CI/CD pipelines for data processing

- Programming experience in Python, SQL or Typescript
- Strong understanding of how data is applied to solve business problems

Bonus Points:

- Dashboard Development in BI Tools (Looker, PowerBI, Tableau)
- Experience with Machine Learning or Data Science concepts.
- AI Automation knowledge and experience
- Data & AI Governance experience

This position is based in the San Francisco Bay Area with an expectation of in-office 2 days per week.

The applicable salary range for this role is $146,000 to $219,000 for applicants located in the San Francisco Bay Area.

Why Mercari:

Small enough to make an impact, but established enough to provide the stability you need to be successful, Mercari is the best of both worlds. At Mercari you are encouraged to take risks. And when you do, you can do it confidently, knowing you have a team and a company that supports you.
