** Who Are We? **

A decentralized court system for dispute resolution in blockchain

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.

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 the team on open source code. 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 will spend most of your time as the project owner of the server side magic that makes Kleros work.

All of our projects use the blockchain as the source of truth, but there are many backend challenges that are crucial to the Kleros ecosystem. You will take on projects that interact with the blockchain, support the user experience, use decentralized protocols, and handle important off-chain data.

There are also opportunities to get involved with smart contract development and product development.

The Ethereum ecosystem is innovating quickly; so above all, you will be learning new things all the time.

Some of the responsibilities include:

  • Back-end development using Node, Python, Go or a language of your choice.
  • AWS infrastructure maintenance.
  • Developing software to interact with the Ethereum blockchain.
  • Architect, build and maintain a sustainable backend server infrastructure.
  • Taking responsibility for improving and maintaining existing projects.
  • Interfacing with and supporting our front-ends decentralized applications.


Salary range: $50k-$100k per year

Equity: 0.05%-0.1%
