fixed-term project engagement｜I18N Engineer

[ ABOUT TENCHIJIN ] Tenchijin Inc. is a Tokyo-headquartered space-tech company and JAXA (Japan Aerospace Exploration Agency) certified venture. Through its land-evaluation and analytics platform, Tenchijin COMPASS, the company fuses earth-observation satellite data, geospatial and environmental layers, IoT and ground-sensor feeds, and clients' operational data with proprietary AI to deliver multimodal analytics for utilities and infrastructure enterprises. Tenchijin's flagship water-infrastructure solution, KnoWaterleak, assesses pipeline deterioration and leak risk from space-derived insights and is used by a growing number of water utilities to prioritize inspection and investment, reduce non-revenue water, and extend asset life. [ ABOUT THE PROJECT ] The Global South Project is an 18-month initiative (October 2026 – March 2028) to design, build, and deploy a scalable, secure, AI-ready analytics platform tailored to utilities and infrastructure operators across Global South markets. The project adapts Tenchijin's satellite-data and GeoAI capabilities to regions facing aging or rapidly expanding infrastructure, constrained budgets, and limited field-inspection capacity — delivering risk assessment and decision-support tools that improve infrastructure management workflows. All positions are contract-based and fully remote, operating as one distributed, cross-border team with English as the working language. [ ROLE SUMMARY ] You will architect the internationalization foundation that lets one codebase serve many languages, scripts, and locales correctly — and you will evangelize I18N practices so every engineer builds world-ready by default. Your work determines how fast and how cleanly the platform can enter each new market. [ Reports To ] Lead Frontend & UX Architect [ Project Language ] English (professional working proficiency or higher required) [ KEY RESPONSIBILITIES ] - Architect and maintain the internationalization framework across frontend and backend: string externalization, ICU message formatting, pluralization, and locale negotiation. - Implement locale-aware handling of dates, times, time zones, numbers, units (metric conventions, currency), and collation throughout the stack. - Ensure Unicode correctness end to end (storage, processing, rendering) and readiness for complex scripts and future RTL support. - Build tooling for the localization pipeline: string extraction, pseudo-localization builds, screenshot generation for in-context review, and CI checks that block hard-coded strings. - Audit code and designs for I18N defects; define and enforce I18N standards, linting rules, and review checklists. - Evangelize I18N best practices: run training sessions, write internal guidelines, and support engineers across teams. - Partner with the Localization Manager to keep the engineering pipeline and vendor workflow seamlessly connected. - Support locale-specific configuration for geospatial content (map labels, place names, coordinate/unit display). [ WHAT WE OFFER ] - A central role in applying satellite data and AI to real infrastructure challenges, with measurable social and environmental impact in Global South markets. - Fully remote, cross-border collaboration with senior specialists across cloud, GeoAI, product, and design. - Competitive contractor compensation commensurate with experience and scope. - Direct exposure to earth-observation technology, including data ecosystems built with Japan's space agency (JAXA). Tenchijin Inc. is an equal-opportunity organization. We evaluate all applicants on qualifications and merit, without regard to nationality, race, religion, gender, age, or disability.
