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.ResponsibilitiesYou’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/JSWhile building distributed applications on top of the Ethereum stack might be one of your tasks, the focus will be on core development.
