Engineering Manager (Platform Engineering) - Mercari

Tokyo
Remote OK - Anywhere in Japan
Full-time
March 21, 2024

Position Overview

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)

Role

We are looking for an engineering manager of one of the teams in the Platform group, who has a strong background (or interest) in platform or infrastructure system development.

Bold Challenges

As an engineering manager of the team, you can lead and support the team to have such a large impact. As the base infrastructure team, the team has lots of stakeholders.

About メルカリ

日本初のユニコーン企業、メルカリは日本で最も多くのユーザー数を誇る、フリーマーケットアプリを運営しています。国籍に関わらず国内外から優秀な人材を大規模に採用しています。シリコンバレーにもオフィスがあり、アメリカ向けにローカライズしたメルカリアプリを開発し、アメリカのフリーマーケット市場でもシェアを拡大しているグローバルテック企業です。

「限りある資源を循環させ、より豊かな社会をつくりたい」。創業者である山田進太郎氏が世界一周の旅で抱いた、そんな問題意識によって生まれたのがフリマアプリ「メルカリ」です。テクノロジーの力によって、世界中の個人と個人をつなぎ、誰もが簡単にモノの売り買いを楽しめる。それにより資源を循環させる豊かな社会、個人がやりたいことを実現できる社会をつくっていきたいと考えています。

これまで中古品の売買は、実店舗で行うのが一般的でした。しかし、お店に行くのに時間がかかること、お店の品揃えが限られていること、販売店が介在することで買い手も売り手も価格が不明瞭になるなどの問題がありました。また、中古品を売買するためのオンライン・オークション・サイトでは、出品手続きが難しかったり、入札に時間がかかったりするなどの問題がありました。

メルカリでは、誰もがスマートフォンを使って簡単に商品を売買することができます。また、配送業者やコンビニエンスストアとの提携により、簡単で安価な配送方法を実現しています。買う側も売る側も個人を対象としたサービスなので、不要なものを簡単に売ってお金にする楽しさや、ユニークな中古品を見つけて買うワクワク感を誰でも味わうことができます。

Japanese Language Policy
Mercari doesn’t require Japanese skills for developers to do their day to day jobs. It’s becoming a pretty international company, but they have many Japanese engineers, so the more Japanese you know the better.

Mercari believes that it’s essential for team members to meet halfway during daily communications. They use the CEFR Framework to understand language levels and guide members in improving their skills. See more info on CEFR and Mercari’s language support here.
Visa Sponsorship
Mercari sponsors Japanese visas for engineers. The only condition is that you meet the requirements of the Japanese government (but this is the case at every company). This usually means that you'll need a bachelor's degree or 10 years of demonstrated work experience in your field.
Paid Leave
- Two days off per week (Saturday and Sunday), Japanese national holidays, New Year's vacation
- Paid Leave (starting with 10 days, adding 1 day each year)

Diversity
There is more diversity in the world than any of us can imagine. Diversity & Inclusion (D&I) is strongly linked to Mercari’s mission as we aim to build a company environment where everyone can be themselves and work to their fullest potential.

Diverse Backgrounds

We already have members with many diverse backgrounds at Mercari. Our goal is for everyone to have equal chances to do their best work, without dividing individuals into groups based on age, gender, sexual orientation, race, religion, physical ability, or any other identifying feature, and without classifying anyone as “majority” or “minority.” We strive to create various policies and initiatives to make this a reality.

No Quotas

Mercari does not set quotas, such as a 50:50 gender balance or a specific number of countries represented, because we feel labeling groups and people in terms of numbers goes against our ideal of respecting the diversity inherent to all individuals. Meaningful efforts towards diversity are reflected not in the quantitative goals many companies tend to rely on, but in the thoughts and behavior of every person within.

Our Focus

Providing fair chances for members of all backgrounds Fostering a culture of learning to allow everyone to reach their full potential Creating an organization built on trust so that everyone working here feels like they truly belong Our first step is for D&I to take root in the thoughts and actions of all members at Mercari.
