[ 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 guarantee that what ships to utility clients works — across services, browsers, languages, and data conditions. You will design and implement the automated test suites that gate every release, covering functional correctness, API contracts, performance, and the geospatial/analytics behaviors unique to this platform. [ Reports To ] Lead DevOps/SRE (functional) / Cloud Operations Manager [ Project Language ] English (professional working proficiency or higher required) [ KEY RESPONSIBILITIES ] - Define the overall test strategy: coverage targets, test pyramid, environments, and release quality gates. - Design, implement, and maintain automated test suites — API/contract tests, end-to-end UI tests, and regression packs — integrated into CI/CD. - Build performance and load-testing scenarios for high-volume API and map-serving workloads; publish benchmark reports. - Test multi-tenant behaviors: data isolation, per-tenant configuration, and permission boundaries. - Validate multi-language builds in cooperation with the I18N Engineer and Localization Manager (pseudo-localization, locale-specific formatting checks). - Verify data-pipeline correctness: ingestion validation, transformation accuracy, and analytics-output sanity checks against known fixtures. - Track, triage, and report defects with clear reproduction steps; own quality metrics and release-readiness reporting. - Coach developers on testability and shift-left quality practices. [ 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.
