Join our global team of world-class engineers working on the Authlete Server!

  • Implement support for new standards related to OAuth 2 and OpenID Connect

  • Add new features to our products and services

  • Investigate and support issues reported by customers

  • Refactor and redesign for the upcoming major release

  • Improve performance, maintainability, and robustness


This position requires very strong, demonstrated skills in Java development. We use Java 11 EE. Our development and production environment is highly containerized so familiarity with Docker or Kubernetes is a plus. You can use your preferred editor, tools, and OS for development.


You must speak English or Japanese well, and proficiency in both is a plus, as well as proficiency in other languages. Reading and writing in English is required for this position.


Depending on your skills and interests you will also have a chance to work on other code-bases and programming languages, such as working on our SDKs that are available for many languages and frameworks. You may be involved in DevOps automation, front-end development, automated tests and conformance testing, and integration with 3rd party, cloud services, or customer systems.


Our work style is flexible; you will be entrusted with responsibility for your work and managing your time. Full remote or hybrid is possible. We have an office at Finolab (fintech startup center) in Otemachi (near Tokyo Station) where you can hang out with co-workers and join events. Full-time permanent or contract, or part-time is negotiable. We have offices in Tokyo (HQ), London, and Dubai, and team members all over the world with a wide variety of backgrounds. We accept candidates from outside Japan who can work remotely and have experience in managing their own time, such as freelancing. We are open to discussing supporting visa application and moving to Japan for members who have worked with us remotely first.

Authlete provides a backend for implementing authorization and identity solutions based on OAuth 2, OpenID Connect, Financial-grade API, Open Banking, and related standards. Our services are widely used globally by customers in a wide range of industries such as fintech, banking, entertainment, healthcare, travel, and media.

Our work style is flexible with regard to both time and location. We have team members located all over the world and a global customer base. The company was founded in 2015 and is headquartered in Tokyo, Japan.
