About the Role

Fast-growing international tech company in Tokyo is looking for a Senior Software Engineer to lead the transition from a core monolith to a scalable Service-Oriented Architecture. You will act as a technical lead shaping architectural strategy, driving domain boundaries, and selecting the modern tech stack to support rapid Asian market expansion.

Responsibilities

  • Evaluate and choose modern, statically-typed languages for future services, prioritizing type safety, concurrency, and developer experience.
  • Partner with product managers to refine technical specifications, define domain boundaries, mentor engineers, and set engineering standards.
  • Design scalable database schemas and distributed workflows that ensure transaction integrity, payment consistency, and high availability.
  • Drive a "you build it, you run it" culture by implementing zero-downtime deployment strategies, CI/CD pipelines, and robust monitoring.

Requirements

  • Demonstrated experience with statically-typed languages such as Go, Kotlin, Scala, Rust, or C#, including async/concurrency paradigms.
  • Proven background designing SOA/microservices while maintaining and refactoring monolithic codebases.
  • Hands-on experience with scalable storage and database solutions (e.g., AWS Aurora, Cassandra).
  • Practical experience with CI/CD tools (GitHub Actions, CircleCI) and monitoring/logging stacks (Datadog, Grafana, Prometheus).
  • Fluent written and verbal communication skills in English with an entrepreneurial, problem-solving mindset.
