[ 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 build the interfaces utility teams use daily: interactive map layers showing infrastructure risk, analytics dashboards, and multi-language UI components. Your work must be responsive, fast on constrained networks, and consistent across the languages and locales of the Global South markets the platform serves. [ Reports To ] Lead Frontend & UX Architect [ Project Language ] English (professional working proficiency or higher required) [ KEY RESPONSIBILITIES ] - Build modular, reusable UI components within the project design system. - Implement interactive map layers and geospatial visualizations (risk heatmaps, asset overlays, temporal comparisons). - Develop analytics dashboards with filtering, drill-down, and export capabilities. - Ensure responsive design across desktop, tablet, and mobile, with performance budgets for low-bandwidth users. - Implement multi-language UI compatibility: externalized strings, locale-aware formatting, and layout resilience for text expansion, in collaboration with the I18N Engineer. - Write component and integration tests; participate in code and design reviews. - Integrate frontend telemetry and error monitoring. - Collaborate with the UX/UI Designer to translate high-fidelity designs into pixel-accurate, accessible implementations. [ 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).
