Lifelong learning. You recognise areas for growth and proactively learn new skills and knowledge for your current and prospective areas of responsibility.
Vision & planning. You can plan your work several weeks ahead and can juggle multiple projects at once. You know when to postpone a task to keep your workload manageable.
Thoroughness. You cover every important aspect of your task leaving out no crucial detail.
Proactiveness and initiative. You offer help if you have spare capacity. You take initiative and pitch your own projects to others.
Critical thinking. You question every judgement, claim or number and can engage in a healthy debate with your teammates.
Dynamic, out-of-the-box mindset. You can challenge existing ways, abandon well-trodden paths and embrace the new in the name of the great.
What we are offering
Competitive Salary
Depending on the candidate's skill level, our target salary range is 14-20M JPY per year for a full-time position and equity compensation (options).
(01)
Flexible Schedule
Outside scheduled team meetings, teammates are free to work on their tasks independently. When to work is a personal choice. Just do not overwork – that is inefficient.
(02)
Autonomy
High autonomy is crucial for us – the small and agile team can achieve a breakthrough if its members are professional and independent. However, we promote helping each other. That is crucial too.
(03)
Low Bureaucracy
What we value most are performance and results, not a strict process following. However, metrics, processes, and documentation are important too. We just keep their priorities low.
(04)
Medical Allowance
Compensation of overseas health insurance and additional medical costs, yearly health checkup.
(05)
Language Courses
Support for English and Japanese language training.
(06)
Other
Visa Sponsorship, Relocation Allowance, Travel Allowance, Monthly commute expense in Japan, Japanese Social Security.

How we are different
Not just an ML
(01)
People tend to think that AI is solely Machine Learning, like ChatGPT (or DALL-E 2, or Microsoft Bing, or ChatSonic). We are building our solution on an alternative architecture which incorporates ML as a part.
Going beyond
(02)
We put much effort into profound research and development of new underlying technologies rather than reusing existing ones. We like to explore unfairly neglected and non-conventional approaches to AI.
Safety and Alignment
(03)
We want to be responsible in our research and development. We don't turn our noses up at AI safety research and take the issue of alignment seriously.
