Summary #︎

At Kamu we are developing a novel Web3 technology that, similarly to the invention of SQL database 40 years ago, will write a new chapter in humanity’s transition towards data economy.

This is your opportunity to join an ambitious early-stage startup that has already secured funding, and work on a technology that will shape the future of data science from a place of relative financial stability.

About us #︎

Kamu is building a unique decentralized network for the exchange and collaborative processing of structured data (whitepaper). Think of it as GitHub on top of a decentralized database, where people and organizations can share near real-time data streams, and data scientists can collaboratively compose them with SQL into high-quality data products ready for use by data-centric apps and for AI/ML. The network guarantees that all data is 100% auditable and verifiable and brings superior automation, accountability, and transparency to the data flows that underpin our society.

Kamu is backed by multiple investors and companies including Protocol Labs (the creators of IPFS and Filecoin) and Dell Technologies.

We are:

• A distributed, multinational company with a presence in Canada, Ukraine, and Portugal
• A highly technical group with decades of experience in big data, distributed software, and PhDs in AI/ML and computer science
• A team that takes pride in delivering quality products and efficient workflows
• Strong believers in Web3, decentralization, and personal data ownership
• Open Source enthusiasts who develop technology in the open, and constantly share progress with the community through publications and conferences.

About you #︎

Your career has been on a steady rise and you are constantly looking for new opportunities to improve your skills and learn new technologies while ideally contributing to projects that can make a real difference in the world and have a high societal impact.

You put the team and the goal before ego and prefer to be a small fish in a big tank, as it gives you more opportunities to learn and better yourself.

You are self-motivated and autonomous - once goal is clear you can be relied upon to drive it to completion while seeking help when necessary.
