Skills
Must have
- Willingness to be based in Tokyo. This is a hybrid role, not a fully remote position, but you do not need to be in Japan already: we sponsor the work visa and support your relocation.
- 5+ years of professional native Android development experience.
- A track record of shipping and operating production Android apps on the Play Store.
- Experience shipping Android apps without AI assistance. You are expected to understand every line of code that ships, hand-written or AI-generated.
- Strong Kotlin skills and deep familiarity with the modern Android stack.
- Comfortable using analytics and Firebase (Crashlytics, Analytics, or similar) to monitor and improve a live app.
- Daily working proficiency with Claude Code and Claude Design. AI-assisted development is our standard.
- A self-starter who can own a product area with minimal direction.
- Professional working English. Japanese is not required.
- Comfortable in a small, fast-moving startup environment.
Nice to have
- Web or React Native experience.
- Experience being in charge of an iOS app, as owner or lead.
- Experience in entertainment, creator economy, or fan community products.
- Experience with payments, subscriptions, or in-app purchases.

Take ownership of the Queri Android app, our flagship product, and lead native mobile development from architecture to release.
About Queri
Queri is a startup building the next generation of fan engagement infrastructure.
Through personalized videos, chat, global fan clubs, and community features, we help creators and fans connect on a deeper level.
We support a wide range of talent, indie idols, pro wrestlers, musicians, comedians, cosplayers, and influencers, helping them deepen fan relationships, monetize, and expand their reach in Japan and internationally.
Queri is already live and generating revenue. From here, we are expanding from one-to-one fan communication into subscription fan clubs, scalable community experiences, and AI-powered products for creators, fans, and entertainment businesses.
We are looking for an experienced Android engineer to take ownership of our flagship app and help shape the future of fan engagement, creator technology, and AI-powered consumer products.
Fan Engagement
Engaging global fans directly through fanclubs, merch, tickets, and community.
B2B Intelligence
Showing where global demand exists for entertainment IP.
Activation
Converting demand into sponsorships, campaigns, events, and market expansion.
The Role
As Tech Lead / Android Developer, you will take over the Android version of the Queri app, our flagship product, owning the native codebase end to end: architecture, implementation, releases, and quality.
You will work directly with the CTO and closely with the CEO, designers, and the rest of the team to plan features, ship them to production, and keep the app fast, stable, and loved by fans and creators.
We are a small team that ships quickly, and AI-assisted development is how we work. Claude Code and Claude Design are used daily across the company, and you will be expected to use them as force multipliers.
That said, we are not looking for vibe coders. You should have deep experience shipping native Android apps without AI assistance, and you are expected to understand every line of code that ships, whether you wrote it by hand or generated it with AI.
This is a hands-on leadership role: you will set the technical direction for mobile, lead development as the team grows, and be the person responsible for everything that reaches the Play Store.
