About Build

Build Minato-ku, Tokyo

Build.io helps teams ship products faster without managing infrastructure. Their engineers work across infrastructure, automation, and AI-integrated pipelines, supporting large-scale customers in the US, EU, and Japan alongside experts in security, AI, and open source development.

About the position

You’ll join a small, highly technical team working across Build.io’s platform and the broader modern development stack. This is a hands-on role for someone who is curious, adaptable, and excited to keep learning across infrastructure, tooling, and product development.

Responsibilities

  • Contribute to the development of Build.io’s PaaS across different parts of the stack
  • Build and improve tooling, systems, and workflows that support modern product development
  • Work across software, infrastructure, and automation depending on team needs
  • Help troubleshoot customer issues and support technical implementations
  • Assist with sales-related technical questions and demos when needed
  • Participate in the on-call rotation and support production systems responsibly
  • Learn from and collaborate with a multidisciplinary technical team

Requirements

  • Degree in Computer Science or self-taught and comfortable with advanced peers
  • 3+ years of professional software development experience
  • Comfort developing alongside AI tooling, ideally asking for token limits to be raised
  • Positive attitude teammate that is not afraid to roll up their sleeves and support technical customer needs, sales implementations, and participate in on-call rotation

  • Experience with containers and orchestration tools such as Docker and Kubernetes
  • Relevant certifications such as CKA, CKS, or CKAD
  • Security-related certifications, or demonstrable experience working on security-focused engineering problems
