Principal Engineer (Developer Productivity) , CTO Office, Tokyo

仕事内容

OverviewAs Money Forward continues to scale our product portfolio and engineering organization, strengthening developer productivity has become a strategic priority for the CTO Office and the broader MF Engineering group. We are evolving our developer experience, platforms, and governance to support increasingly complex products and a growing number of engineers in Japan and Vietnam. To accelerate this transformation, we are looking for a Principal Engineer who can take ownership of developer productivity as a company-wide capability. You will be a key partner to the CTO, engineering leadership, and cross-functional stakeholders in defining and executing this strategy. Responsibilities and DutiesYou will lead developer productivity and developer experience initiatives across Money Forward Cloud and the wider group, working closely with engineering teams in Japan and Vietnam, the CISO and PRE/SRE organizations, as well as Product and management. While architecture and governance leaders own company-wide technical design, you will own how productively developers across the company work and how smoothly they can deliver high-quality software. Bridge the CTO, engineering leadership, and Product to surface real productivity problems, propose data-informed solutions, and align on which value areas to prioritize and invest in first. Make full use of DFP (our Backstage-based developer portal) and evolve it where it provides leverage—so product teams can self-serve common needs such as templates, shared libraries, CI/CD pipelines, standard patterns, and golden paths—treating it as one productivity lever rather than a goal in itself. Define and instrument engineering productivity: select appropriate metrics (such as DORA, SPACE, or team-specific indicators), measure honestly using our productivity-data stack (Apache DevLake, BigQuery, Looker Studio), and use these insights to identify friction points and demonstrate impact. Lead developer-experience and tooling programs end-to-end, including developer tooling, CI/CD and build-time improvements, internal documentation and templates, and especially the rollout of AI tools, agents, and workflows on our internal AI Platform—covering technical design, implementation, and adoption. Identify practices that work well in specific teams and scale them across the organization by codifying patterns, sharing knowledge, and driving adoption through communication, enablement, and change management. Partner with the CISO and PRE/SRE organizations on security and reliability initiatives that touch developer experience, ensuring secure and reliable defaults without owning those mandates directly. Partner with the FinOps owner to embed cost awareness into developer tooling and golden paths, helping teams make cost-effective architectural and operational choices while not owning the overall cost program yourself. Support the architecture and governance review process where it intersects with developer experience, ensuring that standards and guidelines are practical, discoverable, and easy for teams to adopt. Communicate clearly and credibly with both engineers and executives in English and Japanese, including proposals, status updates, decision records, post-implementation reviews, and success stories. Required Skills and Experience Extensive experience as a senior or principal-level engineer leading cross-team or organization-wide initiatives related to developer productivity, platform engineering, or developer experience. Strong hands-on experience with modern CI/CD pipelines, build and test automation, and developer tooling for cloud-native applications. Practical experience designing and operating internal developer platforms or portals (e.g., Backstage or similar), including defining golden paths, templates, and shared services. Solid understanding of software engineering metrics and productivity frameworks (e.g., DORA, SPACE), including the ability to design meaningful metrics and avoid misuse. Experience working with data pipelines and analytics tools (e.g., Apache DevLake, BigQuery, Looker Studio or equivalents) to collect, transform, and visualize engineering data. Proven track record of partnering with security, reliability, and operations teams to embed good practices into development workflows. Demonstrated ability to lead technical design, run experiments, and deliver incremental improvements in complex, multi-team environments. Excellent communication skills in both Japanese and English, with the ability to tailor messages to engineers, managers, and executives. Preferred Skills and Experience Experience building or operating large-scale, multi-language or multi-region engineering organizations, especially involving Japan and other countries (e.g., Vietnam). Hands-on experience with AI-assisted development tools (e.g., code generation, code review, test generation) or implementing AI workflows into existin
