Staff Quality Engineer, Workflow Platform, Nagoya

Overview

You’ll lead quality engineering for a new shared platform that lets Money Forward product teams add approval and document-submission workflows without building those capabilities from scratch. Working across REST APIs, Kafka-based events, micro-frontends, and multi-tenant infrastructure, you’ll build confidence in the behaviours no single component team can validate alone - including service contracts, end-to-end workflows, failure recovery, performance, and reliability.

You’ll join the QA team as a Staff IC, reporting to the QA Manager and working across the teams that build and integrate the platform. Your initial focus will be taking the platform from its first staging release through hardening and production launch. You’ll work hands-on alongside developers and component QA engineers: identifying systemic risks, improving testability and observability, automating critical validation, and turning evidence into clear release-readiness recommendations. Beyond launch, you’ll establish the quality architecture and engineering practices that allow the platform to evolve safely.

Responsibilities and Duties

• Define and evolve a risk-based quality strategy for the platform, covering service contracts, cross-service workflows, tenant isolation, failure recovery, performance, and reliability.
• Design and implement automated validation at the layers where it provides the most confidence, including API and event contracts, service integration, and critical end-to-end workflows.
• Lead performance and resilience testing to expose capacity limits, latency risks, unsafe retry behaviour, and failure modes before they affect production.
• Work with developers to improve the platform’s testability and observability, including useful telemetry, controllable test environments, and reliable test data.
• Bring together evidence from component teams and system-level testing, clearly communicate residual risk, and make release-readiness recommendations.
• Coach component QA engineers and developers in platform quality practices, and create reusable approaches that allow teams to validate their own changes effectively.

Required Skills and Experience

• Quality engineering for a shared platform. You’ve been technically responsible for quality for a production platform or shared service used by multiple products or engineering teams. You can show how you identified and addressed risks between the platform and its consumers - for example, contract compatibility, integration behaviour, tenant isolation, or coordinated changes across systems.
• Hands-on test and software engineering. You’ve designed and implemented maintainable automated tests and supporting tools for production systems, including APIs, service integrations, and end-to-end workflows. You’re comfortable reading application code, debugging failures across system boundaries, and contributing improvements directly.
• Performance and resilience engineering. You’ve designed and run load, stress, or failure-recovery tests for production systems. You can interpret application, infrastructure, database, and messaging telemetry to find bottlenecks and failure modes, then work with engineers to address them.
• Technical leadership across teams. You’ve led a quality initiative involving multiple engineering teams without relying on line-management authority - for example, aligning teams on risk, establishing shared practices, coaching engineers, and communicating evidence clearly enough to support release decisions.
• DevOps & CI/CD ecosystems. Basic proficiency with DevOps and CI/CD tools (e.g., CircleCI, GitHub Actions, ArgoCD) to support high-frequency platform delivery.
• Scalable automation architecture. Experience architecting robust, scalable test automation frameworks that integrate seamlessly into CI/CD pipelines and handle multi-tenant complexity.

Preferred Skills and Experience

While not specifically required, tell us if you have any of the following:

• Distributed and event-driven systems. Experience testing production systems made up of multiple independently deployed services, including API and message contracts, partial failures, schema compatibility, delivery semantics, ordering, retries, and idempotency.
• Micro-frontend integration testing. Experience validating embedded web components and their interactions with host applications, ideally using browser-automation tools such as Playwright.
• Cloud-native performance analysis. Experience combining load-testing results with metrics, logs, and traces from Kubernetes-based systems to isolate application, database, or messaging bottlenecks.
• Workflow or financial-software experience. Experience testing systems involving approval routing, delegation, permissions, auditable state transitions, or financial data.
• Experience in AI development and/or experience in using AI tools to improve development processes.
  • Money Forward is at a major turning point, shifting "from Cloud to AI." We are currently driving "AX (AI Transformation)"—the next step beyond DX—with the goal of providing "Digital Workers," where AI agents autonomously execute tasks. As we enter a phase of evolving into Japan's No. 1 back-office AI company by integrating AI agents into all of our products in the future, we are looking for individuals who can contribute to AI-driven development and value creation.

Language Requirements

• Japanese Language Requirements：No Japanese Language Requirement
  • The ability to collaborate with Japanese-speaking colleagues or read Japanese product documentation is helpful, but Japanese is not required for this role.
• English Language Requirements：Professional communication in English. 
  • You can discuss technical designs, write clear quality and risk assessments, and explain release-readiness evidence to engineers and stakeholders in English.

Who We’re Looking For

We are looking for someone who is passionate about building high-quality, reliable products and who sees QA as a strategic function rather than a final checkpoint.

You should enjoy working closely with cross-functional teams, facilitating discussions, and aligning diverse stakeholders around quality goals.

You are comfortable working in an evolving environment, where requirements and technologies change, and you proactively adapt testing strategies accordingly.

If you are motivated by the opportunity to shape QA practices in an AI-driven, cloud-native environment, you will thrive in this role.

Technology Stack

• Backend: Kotlin (Spring)
• Frontend: React
• Platform: AWS, Kubernetes, Terraform

Work Environment

At Money Forward, we provide an environment where we can create world-class services together, and we are looking forward to welcoming you.

• Provided PC Specs: We provide PCs equipped with the latest CPUs (MacOS or Windows). Custom-made PCs tailored to business requirements and replacements with the latest OS are also possible.
• Systems to Enhance the Development Environment: Peripheral devices necessary for work (such as displays, mice, keyboards) can be purchased as office supplies. Generally, you can choose from standard products (catalog), and if conditions are met, you can apply for non-standard products as well. (*Excluding certain group companies)
• Money Forward Library: We have a library system where you can freely borrow books, ranging from technical books to management books. Desired books can be purchased at the company's expense.
• Referral Driven: We cover the cost of recruitment meals. There is a referral reward system.
• Conference Participation Support: The company partially covers participation in domestic and international conferences, such as RubyKaigi and Google I/O.
