Blockchain and Ethereum Developer

brainbot technologies is working on cutting edge blockchain development.

We are a major contributor to Ethereum, a Blockchain 2.0 system which supports turing complete smart contracts and is a platform for rapid development of decentralized applications (DApps). The platform also comes with a secure messaging infrastructure (Whisper) and a DHT based storage (ipfs).

Our core product is HydraChain which is an extension to Ethereum for enterprises.

You’ll work on the client core and/or build applications based on the Ethereum and HydraChain platforms. Most of the work will be on open source software.

To get an idea about the tools we are using, please take a look at the code:

As we are relying on PyPy and gevent, we are currently using Python 2.7 but plan to move to Python 3 once PyPy is compatible with Python 3.3.

Note: We do not use Django. The architecture of decentralized applications which are build on top of Ethereum is: local ethereum-node <- jsonrpc -> HTML/JS
While building distributed applications on top of the Ethereum stack might be one of your tasks, the focus will be on core development.
