Toss Lab, Inc.Toss Lab Inc. is the developer of “JANDI” which is a cloud communication service

for collaboration within a team. JANDI eliminates the ine�ciency that occurs in

collaboration and stimulates communication between employees. In order for

us to provide this service we need more than anything exceptional developers,

and we are devoting ourselves beyond any startup to seek talent with the same

DNA as the current developers. Our vision is to change the communication

market by providing a product with the best technology created in an

environment where developers create their own culture and are recognized.

We are recruiting passionate developers that can share this dream from the

initial stage and experience the upcoming stages of growth together.

JANDI is serviced JS-based for Web, Native iOS, and Android.

For a fast market response it will be hard for us to avoid Technical Debt ,

but to make up for it we are in the process of applying CI(xUnit, Jenkins etc).

We actively use Wiki(Con�uence), ITS(Jira, New Relic), and

Communication tool(JANDI) and introduced Scrum (Jira Agile) from

the beginning, �ne tuning the development culture to �t us.

UX (User Experience)

JiHoonPeter

When developing based on a single page

application, the application structure can get

complicated and messy. So similar to the back-end

we invest a lot of time in making the application

structure elaborate and simple.�We put quality

before development of functions, so we would like

a person that is not bothered by aggressive

refactoring work based on test codes.

Analytics Statistics Concept, SQL, Java

RDBMS, NoSQL (MongoDB),

BigData Analysis (Hadoop),

GA (Google Analytics) or Mixpane,

and other Languages

I would like a person with a basic understanding

of statistics to lead or perform the research

together. A person that has experience with

big data would be even better to match our

future needs for it.

I can freely discuss structural

basis of Java, in order to �nd

Just as it is important to e�ectively deliver your own opinion, it is also important to

logically respond to other people’s opinions.�Psychologically it is said that the �rst

reaction to an opinion di�erent from my own will be emotional.�Jandians engage in

dialogue in the form of opinion vs opinion, regardless of the counterpart’s authority or

age. We believe the ability to consciously set aside emotions when engaging in

dialogue is an e�ective method of drawing a productive conclusion.

MY OPINION OPPOSING OPINION

CENTER

Developer Job PostingToss Lab, Inc.

We ponder endlessly on raising the quality for a successful project.

But insisting only on raising quality and not responding quickly to the market

can a�ect the whole business in a startup. Jandians always ponder on the balance

between speed and quality to ensure that the Technical debt that arises from

following the market response is not accumulated.

2. Balance Between Speed and Quality

SPEED TREND

WE SHOULD HAVE THE FUN OF FOLLOWING USEFUL TRENDS.

Jandians have strong urge for growth. Everyone has a surprising amount of research

spirit for new technology.�However we are cautious not to become a trend shopper

that would hastily apply these to our service. We are equally cautious of a narrow

viewpoint of trying to solve all problems with only one technology that we would be

con�dent with.

3. Balance Between Trend and Practicality

If global service operation experience, full stack development skills, and experience

working at a rapidly growing startup are a major part of your personal goal, we want you.

By nature of startups, responsibility in your work is the most important quality.

We are not looking for people that are simply looking for a job.

If you have a lot of interest in open source projects, development community,

blogs, and other activities, we want you.

We want people that can build a spectacular development culture

(Scrum, TDD, Code review) with us together.

We want to work with these type of people.
