QLDB is serverless and highly scalable, allowing customers to scale effortlessly to support the demands of their applications.

We are looking for software engineers who thrive on creative problem solving and enjoy the challenge of operating mission critical systems under extreme loads. An ideal candidate will be able to dive into complex database and distributed systems problems to invent simple and elegant solutions.

The simplicity has given Mixin the ability to irreversibly confirm transactions in seconds.

The mainnet has been running since Feb 2019 and processed millions of real Bitcoin transactions. Compared to a similar project Bitcoin Lightning Network, Mixin has more than 1200 BTC in the network and much much more active transactions.

Mixin Messenger is a unique digital wallet and end-to-end encrypted messenger built on Signal protocol. We see it as an important entrance to Mixin Network, to help people transfer all their crypto assets and their messages securely.

The Job

Most of our engineers are somewhat full-stack engineers, and with focus on some specific platforms. 3 on server, 3 on Android, 2 on iOS, 2 on deskotp, 2 on web, and of course they have some interleaves.

Now we are expecting you to have excellent skills in web technology, and the passion to build open source project with great user experience. You will mainly have three kind of works to focus, but you are free to choose some new one.

  1. Open data visualization. Our code is open source, and Mixin Network is a public ledger. So we need to build an explorer for it.
  2. Create the framework for Mixin Messenger bot. Our Messenger has many active users, they use many popular bots, but we still don't have an bot framework for developers. You may create the framework to help developers creating better bots.
  3. Build useful and interesting bots. We build our own bots for both internal use and public use, some are just showcases maybe.
