使用ツール

Overview

• As 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 Duties

• You 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.
