About this role

As Principal Engineer in the CTO Office (Developer Productivity), this role leads developer productivity and developer experience across Money Forward Cloud and the wider group, spanning engineering teams in Japan and Vietnam. Working closely with the CTO, engineering leaders, CISO, PRE/SRE, and product teams, the role surfaces productivity friction, proposes data-driven solutions, and aligns stakeholders on where to invest. Responsibilities include evolving the Backstage-based internal developer portal (DFP) with templates, shared libraries, CI/CD pipelines, and golden paths; defining and measuring productivity using DORA/SPACE metrics via Apache DevLake, BigQuery, and Looker Studio; leading developer-tooling programs end to end, including CI/CD, build-time improvements, documentation, and AI tools/agents on the internal AI platform; and standardizing effective practices across the company. The role also supports architecture/governance reviews and FinOps initiatives where they touch developer experience, and communicates proposals and results to engineers and executives in both Japanese and English. Requires senior-to-principal-level experience leading cross-team or company-wide developer productivity or platform engineering initiatives, hands-on experience with modern CI/CD and internal developer portals, and business-level fluency in both Japanese and English.
