• We expect you to be a good engineer and be comfortable with the usual developer workflow, such as reviewing others’ pull requests, being ready to work on a new part of the codebase, debugging bugs here and there, and documenting the decisions and steps taken
• Communication is asynchronous because the team (and the company) are distributed in several time zones. It happens in English, so you must be fluent enough to communicate your ideas and designs and participate in discussions
• A good candidate would also be proactive, passionate, thorough, and have an eye for detail. We would like you to be open to learning new things
• Prior experience with blockchain is a nice bonus but otherwise, it is good if you have a strong understanding of distributed systems in general
• We are looking for someone with a strong Haskell background
• An ideal candidate is familiar with the wide Haskell ecosystem of libraries and has worked or at least made an effort to understand the concepts behind fundamental libraries and concepts like lenses, Template-Haskell, CBOR, GHC Generics, STM, Effects systems, mtl, pipes, SOP, etc
• We use only some of these, but listing them gives a general overview of our expectations

Desirable

• IO Global is seeking a Senior Software Engineer (Haskell Developer) to join its Consensus team
• The Consensus layer is an open-source implementation of the Ouroboros family of Consensus protocols written in Haskell. It ties together the Ledger, Network, and Cardano Node components
• We work closely with the teams that develop them, asking and answering questions and making and responding to requests. The Consensus layer also handles block forging and storage, so serialization is also an essential part of the codebase
• We favour writing understandable Haskell, emphasising documentation and readability to explain the complex choices behind our code
