About Mercari

We believe the world needs a place where people can exchange their loved goods. That’s why we built Mercari—to connect people who want to buy and sell things of emotional value through their mobile phones. Mercari has grown to become a leading community-powered marketplace that brings together millions of people every day.

Mercari Dev Meetups

Position

Remote work is also possible.

Mercari’s culture has been central to the company since our founding, with the three core values of Go Bold, All for One, and Be a Pro. In addition, the “Trust & Openness” value was introduced to embody our culture of mutual trust, where information remains transparent and rules are kept to a minimum. Regardless of how big Mercari gets, our culture is essential to achieving our mission and will be promoted throughout our organization.

Team

Platform group is responsible for helping engineers at Mercari and its subsidiaries to build and deliver better products to our customers. We provide infrastructure and developer experience and make the service more reliable and engineer’s work easier.

Currently, the Platform group consists of 4 teams: Platform DX, CI/CD, Network and Platform infra. Platform DX is working on improving the developer experience. CI/CD is providing testing infrastructure, toolings, and the delivery system. Network is responsible for edge, Cloud, and data center networking. Platform infra is working on base Cloud management and observability tooling. By working with multiple layers of teams, we achieve the mission of the Platform group.

Recent or in-progress projects

The following is some of the recent or in-progress projects which Platform group is working on:

Provide a temporary role granting system for Kubernetes RBAC and Google Cloud Platform IAM. This allows developers and SRE not to have modification roles by default and get it only when required. With it, we move forward to Zero touch production and make the platform more secure (Platform DX)
Provide Kubernetes abstraction framework. Currently, developers need to handle the wall of YAML to deploy services. With this framework, we abstract many fundamental configurations away from developers' hands and reduce the cost of deploying new services (Platform DX)
Introduce Istio service mesh and working on from stabilization to supporting gradual adoption to 100+ microservices (See more details on talk at IstioCon) (Network)
Provide canary delivery pipelines on Spinnaker by leveraging the Istio feature provided by the Network team. The pipeline can be defined by the code and make it easy to generate and change by pull request (CI/CD)
Provide secure CI systems for automated infrastructure continuous delivery. We have terraform monorepo which manages different team’s service infrastructure. Before CI was executed by a single strong account, which has huge risk if leaked, but now it’s executed with delegated least privileged account for each team (Platform infra)
Migrate from zonal and routes-based Kubernetes cluster to regional and VPC-native Kuberntes cluster without any downtime and with less impacts on the product development. This cluster is our main multi-tenant cluster which runs 100+ microservices and receives 80,000+ req/sec (See more details on our engineering blog)
