About Cocone

With their mobile apps, Cocone wants to create a fun digital environment where people can interact and share experiences. They hope their apps will help their users have fun and feel even more fulfilled with their lives.

Cocone is hiring more members to work on building their in-house products, doing everything from ideation to design to engineering. They hope to further increase the speed of development and handle everything from ideation to design to marketing the products.

Visa Sponsorship
Cocone supports candidates in getting a work visa from the start of their employment to the end (for JP office).
Paid Leave
- Weekends and holidays
- Annual paid leave, congratulation or condolence leave, New Year's leave, special leave, maternity leave, childcare leave, etc.More than 120 days off per year

Engineer Interview Process
(1) Document screening

Resume (Japanese 履歴書 with photo) Curriculum vitae (Japanese 職務経歴書)

(2) First interview: Member of leadership

It is not necessary to bring paper documents (electronic is fine)

(3) Second interview: Business managers or executives
- 1. Resume
- 1. Online personality test (about 5 minutes)
- 1. Proof of your annual income (a copy of your withholding tax or most recent monthly pay stub / data can be sent)
There’s typically around 1 week between each step, but timing of the steps and requests for submissions may vary depending on the selection process.

It normally takes 1-2 months from interview to hire.
Remote Work
Currently, Cocone allows employees to work remotely up to 8 times per month.
Work style
- Normally, Cocone uses a “flex time” system with core hours from 11:00 AM to 4:00PM. But with the COVID-19 situation they’re using a full-flex system with no core time.
- Cocone has a system that allows employees with children to spend 1 hour a day on childcare and reduce their work hours to 7 per day instead of 8. There’s no decrease in compensation for anyone utilizing this system.
Diversity
Cocone has a diverse group of employees, so it’s a relatively easy environment to get used to even for non-Japanese new members. They provide Japanese classes as well as regular events to help members interact with their co-workers and build relationships.
Parents and Family
Many of Cocone’s members have children, so they’ve introduced a childcare free time system. They’re also understanding of the need to take time off to handle issues related to childcare (sudden sickness etc).
Working at COCONE
- Cocone's team is flat and there is no job hierarchy.
- In a 2019 ranking of "companies worth working for" in Japan (in which 480 companies participated), Cocone ranked 27th. We are planning to hire more engineers as our business expands, especially for Pokemini（ポケコロ）. We're aiming to create an environment where you can grow as an engineer and enjoy Silicon Valley-level benefits.
