Coopérative Kleros jobs

A decentralized court system for dispute resolution in blockchain

** Who Are We? **

Kleros is a tight-knit team, supported by a large community, that works together to democratize access to justice using cutting edge technologies. We are deeply integrated with the Ethereum ecosystem, but our mission transcends it.

Our core is a blockchain-based decentralized protocol that crowdsources arbitration. In other words, an online court system, secured by cryptography and game theory. Check out our website to learn more (kleros.io).

We are community leaders, crypto- economists, designers, engineers, makers, mathematicians, thinkers, and writers. Our tasks are incredibly varied and exciting. Building a digital justice system and integrating with applications comes with all the usual challenges of your favorite tech companies plus so much more!

** Who Are We Looking For? **

We’re proud to have created an environment where everyone feels safe speaking their minds, and everyone is heard and considered. Collective thinking is the best way for everyone to succeed.

We place a lot of trust in each other, and we have flexible work schedules. You are welcome to relocate to work out of the Lisbon’s office, but almost all of our team works remotely.

Ultimately, this means we look for exceptional people who will share our vision. We compensate them competitively and ensure they are motivated to succeed and grow together. The % indicated in the `Equity Range` field corresponds to a PNK token allocation. You will also get voting rights in the Kleros Cooperative.

Job Description

Are you passionate about decentralization and building the new governance systems that will make the old ones obsolete? If so, read on.


What Will You Do?

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!
