Careers
Build the Future of Search
DemandSphere is a small, focused team building the platform enterprise brands use to understand their presence across SERPs and AI search. We're based in Tokyo with team members worldwide.
Tokyo Office
Founded in Tokyo in 2010. Our engineering and product teams are based here, with deep roots in the Japanese and APAC search ecosystem.
Remote-First
Most of the team works remotely across time zones. We care about output and ownership, not hours in an office.
Y Combinator S10
We've been building in this space for 15+ years. Profitable, independent, and growing - no fundraising pressure, just product focus.
How We Work
Ownership over process
We're a small team. Everyone owns their area fully - from architecture to deployment. No ticket queues, no handoffs.
Data is the product
We process petabytes of search data daily. If you're excited about data engineering, NLP, or building systems that work at scale, this is the place.
Search is changing fast
AI Overviews, LLM answers, agentic search - the landscape shifts weekly. We build for what's next, not what was.
Global by default
Our customers span 200+ markets. Our team spans continents. English and Japanese are both working languages.
No open positions right now
We're not actively hiring at the moment, but we're always interested in hearing from exceptional people - especially in engineering, data science, and search.
