株式会社天地人のfixed-term project engagement｜Site Reliability Engineer (SRE)の求人

[ 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 define what 'reliable' means for this platform and then engineer it: SLIs and SLOs for every client-facing service, proactive monitoring that catches degradation before users do, disciplined incident response, and relentless elimination of the failure modes and toil that erode reliability over time.

[ Reports To ]
Cloud Operations Manager / Senior DevOps Manager
[ Project Language ]
English (professional working proficiency or higher required)

[ KEY RESPONSIBILITIES ]

• Define SLIs/SLOs (availability, latency, freshness of analytics data) for platform services with the Cloud Operations Manager; implement error-budget tracking.
• Build and tune monitoring, alerting, and dashboards; drive alert quality (actionable, low-noise) across the stack.
• Serve in the on-call rotation; lead incident response as incident commander for major events, and author blameless postmortems with tracked follow-ups.
• Engineer reliability improvements: redundancy, graceful degradation, retry/timeout policies, capacity planning, and load testing.
• Automate operational toil — deployment safeguards, self-healing, runbook automation — in partnership with the Lead DevOps/SRE.
• Perform production-readiness reviews for new services and tenants before launch.
• Analyze reliability trends and report SLO attainment; recommend prioritization when error budgets are at risk.
• Contribute chaos/failure-injection testing to validate resilience assumptions.

[ 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.
