The APS Team boasts a highly motivated, skilled, talented, and friendly team spread across Tokyo, Singapore, India, and China. We are looking for someone who can quickly integrate and collaborate effectively with our team.

We are seeking a Staff Engineer to join our team and help us define the next generation of our advertising platform. This is not just a coding role; it is a position of architectural and technical cultural leadership.

You will own the end-to-end product development lifecycle, leveraging a modern tech stack and AI-augmented workflows to deliver high-impact solutions. We are looking for a technologist who doesn't just keep up with the industry, but shapes it—someone who thrives on building scalable systems, mentoring the next generation of engineers, and integrating AI to push the boundaries of productivity and software quality.

If you are a builder who values technical rigor, thrives in cross-functional environments, and is eager to contribute to Rakuten’s expansive global ecosystem, we want to talk to you.

Responsibilities:

Project Execution & Engineering Excellence

  • Technical Leadership: Translate complex business requirements into robust, scalable, and maintainable technical specifications and architectural designs.
  • Lifecycle Ownership: Own the full SDLC—from initial design and implementation to deployment, monitoring, and proactive maintenance across all environments.
  • Quality Assurance: Conduct rigorous code reviews, ensuring adherence to design patterns, security best practices, and long-term maintainability.
  • System Stewardship: Maintain a deep understanding of the product ecosystem to identify technical debt and architectural bottlenecks. Proactively propose and lead initiatives to refactor or enhance systems for better performance and scalability.
  • AI-Driven Productivity: Leverage advanced prompt engineering to automate repetitive tasks—such as documentation generation, legacy code refactoring, and test suite creation—to maximize team bandwidth.
  • Partnership: Act as the primary technical bridge between Product, Design, and Engineering. Translate high-level business objectives into clear, actionable technical plans.
  • Team Growth: Actively mentor junior engineers and interns. Foster a culture of technical excellence by providing constructive feedback, guiding career progression, and promoting best practices in software design.

Requirements:

  • Experience & Impact: 8+ years of professional software engineering experience, with a proven track record of leading complex, large-scale web application projects from inception to production.
  • Architectural Mastery: Deep hands-on expertise in Java (Spring Boot/Batch) and Cloud-native architectures (GCP ecosystem: BigQuery, DataProc, Composer). Ability to design for scale, performance, and high availability.
  • Data Strategy: Strong proficiency in both relational (MariaDB/MySQL) and NoSQL (MongoDB) databases, with the ability to choose the right data storage strategy for specific architectural needs. AI-Augmented Engineering:
  • Agentic AI: Demonstrated experience in designing or implementing Agentic AI workflows (e.g., using frameworks like LangChain, n8n, dify, or custom agent orchestration) to solve complex business problems.
  • Analyzing complex business systems, industry requirements and governance, and creating solution designs from them
  • Soft Skills & Ownership: A "get-things-done" mindset with demonstrated accountability for system health and team output. Excellent communication skills, with the ability to distill complex technical constraints into business-friendly insights.

Technical Proficiencies

  • Languages & Frameworks: Java (Spring Boot/Batch), JavaScript/TypeScript (HTML5/CSS3).
  • Data & Infrastructure: MariaDB/MySQL, MongoDB, GCP (BigQuery, DataProc, Composer).
  • Tools & Process: Version Control (Git), Agile/Scrum, Task Management (Jira).

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
