Description

[Introduction]

Our Mission:
Mercari is a Japan-based company with the mission of “create value in a global marketplace where anyone can buy & sell.” Having continuously worked toward this goal since our founding in 2013, we are now transforming from a startup into a global player. While this transformation brings its own specific set of challenges, we believe that solving them one after another will allow us to fully achieve our mission. Are you interested in working together to take on these exciting challenges?

Our Culture:
To achieve our mission at Mercari, our organization and each of our employees share the same values and perspectives. Our individual guidelines for action are defined by our three values: Go Bold, All for One, and Be a Pro. Our organization is also shaped by our four foundations: Sustainability, Diversity & Inclusion, Trust & Openness, and Well-being for Performance. Regardless of how big Mercari gets, the culture will remain essential to achieving our mission and something we want to preserve throughout our organization.

We invite you to read the “Mercari Culture Doc,” which summarizes the behaviors and mindset shared by Mercari and its employees. We continue to build an environment where all of our members of diverse backgrounds are accepted and recognized, and where they can thrive while holding dear Mercari’s culture.


[Position Overview]

Work Responsibilities:
At Mercari, we have been making changes in order to implement a microservice architecture on the backend of our app. However, some of our core systems (for example, the Item Transaction feature) are still running as part of the PHP monolithic application that has supported our growth so far. Our team is responsible for developing and maintaining these core systems. Given that the systems are complex and have a long history at Mercari, agile development remains a challenge for us. To solve this, we have to ensure that our core systems are loosely coupled in order for us to both augment these systems and contribute to our business growth going forward.

The Mercari Engineering Division has defined this new direction as building a "Robust Foundation for Speed." In order to achieve our company mission under this new direction, rather than migrating to microservices, we have taken on a more essential and worthwhile challenge: modularizing. Specific work responsibilities for this position include the following:
・Developing and maintaining core features (PHP or Go, etc. as needed)
・Designing loosely coupled/modular systems
・Working with PMs on a series of development tasks (plan, design, implementation, QA, release, etc.)
・Investigating inquiries from customer support or other development teams
・Conducting system operation tasks, including responding to alerts while on call

Bold Challenges:
Besides your software engineering skills, in this position, you will be able to utilize comprehensive problem-solving skills. You will need to approach these problems by setting and testing hypotheses, and you will need a lot of curiosity and attention to detail in order to tackle core systems that run a huge number of item transactions everyday. These are important systems that handle user assets, so it’s important to go beyond our team’s domain to understand the features’ end-to-end behavior and how they relate to other features. Some features, however, can be hard to fully understand simply by reading the code because they are too complex or old. This will require that you embrace some level of uncertainty and strategically set and test hypotheses to check them. Additionally, you will need to always keep your goals in mind and try to find solutions thinking outside the box.

Required Experience:
・Shared belief in Mercari’s mission and values
・Experience developing and operating systems for large-scale products, selecting technologies and improving their codebase
・Experience in API development using programming languages such as Go, PHP, or Java
・Experience in designing and developing with databases (MySQL or similar RDBMS)
・Ability to design and develop products while considering performance and scalability
・Extensive knowledge of object-oriented software development, networks, memory management, and software testing
・Good communication skills to collaborate with stakeholders and teammates on product development 

Preferred Experience:
・Domain knowledge in e-commerce, order management, payments, shipping and delivery, etc.
・Experience with project management or team leadership
・Experience with Scrum
・Experience developing and operating systems using microservice architecture
・Knowledge of and experience with databases (RDBMS/NoSQL), networks, Linux, monitoring systems, logging, and SLO/SLA
・Experience with software development in the cloud (GCP, AWS or Azure)
・Experience contributing to an open-source project

Language Requirements, fulfilling either of the following combinations:
・English: Proficient (CEFR - C1) / Japanese: Basic (CEFR - A2) preferred
・English: Basic (CEFR - A2) preferred / Japanese: Proficient (CEFR - C1)
