Software Development
Blockchain / Web3, Software Engineer
You will be part of Kleros’ software development team, working closely with our CTO and our Lead Developer. You will develop software needed for Kleros to run: write code, participate in code reviews, conduct tests and deal with potential bugs and vulnerabilities reported through our bug bounty programs and audits.
You can work remotely. Even though there are not set hours (apart from a few weekly team calls), you will be expected to deliver high quality work within the defined deadlines. Kleros is more of a close-knit family than a hierarchical team. Your input and suggestions will be heard and we encourage debate and discussion.
You will have plenty of freedom and responsibilities and are expected to be a pro-active member of our team. You’ll have the chance to be one of the pioneers of the blockchain revolution and decentralized justice!
