Careers
Build the product
and the business with us.
TokyoScaler is a Tokyo-based technology company building generative AI products and taking on contract development. We are hiring people who build, people who bring in the work, and people who keep the business running. Join full-time, on contract, or as an intern — whichever fits you.
Open positions
One interview, no resume required. "I just want to hear more" is a perfectly good reason to reach out.
Full-time / Contract
Engineer
Own the work end to end, from shaping requirements through design, implementation, and operations. Contract development, our own products, or joining a client's team — we adjust the mix to what you want.
- Professional experience in web, mobile, or backend development
- Experience with TypeScript / React / Flutter / Python is a plus
- Please prepare a skill sheet and a portfolio (no resume needed)
Full-time / Contract
Corporate Sales
Open new contract development and AI adoption deals, then carry them through proposal, quoting, and close. Building the proposal together with our engineers is part of the job.
- Comfortable with everyday IT tools — we run on SaaS and generative AI
- B2B sales experience welcome (IT industry experience not required)
- English, Korean, or Spanish is a plus
Full-time / Contract
Generalist
A broad role across sales, operations, PR, and back office — whatever the business needs to grow. You take part in deciding what we do, from the start.
- Comfortable with everyday IT tools — we run on SaaS and generative AI
- Able to think and act independently
- No prior experience in the role required (potential-based hiring)
Internship / Contract
Internship (Engineering / Business)
Not practice exercises: you work on code we ship to clients and on inquiries that actually arrive. Everything you write gets reviewed and returned with feedback.
- For engineering: basic programming knowledge (any language)
- For business: no experience required
- From around 8 hours per week, adjustable around your studies
Why work with us
AI is in production here
We ship generative AI features to clients and use AI in our own work. Nothing stops at a proof of concept — it has to actually run.
Real ownership
In a small team you take part in deciding what we do, regardless of seniority or title. Roles and stages aren't split into narrow slices.
Every position is fully remote
Work from anywhere in Japan, on flexible hours you can fit around your studies, your main job, or your life.
