Blockchain Engineer

The Fluence on-chain protocol is an essential part of the project. The on-chain part serves as a global medium that stores application configurations and dependencies, controls access rights against licenses issued by authors, and facilitates payments. We are looking for a seasoned engineer, expert in distributed systems, with previous experience of building and deploying blockchains.

Your challenges:

  • Probabilistic billing model for computing resources based on cryptographic computation proofs
  • Implement an epoch-based payment model for a two-sided computing marketplace
  • Staking and slashing protocols
  • Two-sided computing marketplace that dynamically matches resource providers and customers, on-chain and off-chain
  • Working with Filecoin EVM and Wasm actors

We expect:

  • 4+ years in a solidity engineer role
  • Hands-on experience with distributed consensus protocols, Byzantine fault tolerance (BFT)
  • Hands-on experience with cryptographic primitives, public key infrastructure, data and privacy protection techniques
  • Basic understanding of cryptographic algorithms
  • An interest in decentralized technology and Web 3

Nice to have:

  • Experience with Substrate, Tendermint, or other implementations
  • Background in cryptography, networking, or academia
  • Experience with Rust

Location: Remote

Commitment: Full-time

About Cloudless Labs

At Cloudless Labs, we are working on new decentralized network protocols to make the internet more open and secure. We believe that open source and open protocols enable better technology for the future of humanity.

Cloudless Labs is a distributed team of engineers residing across the US, Asia, and Europe. Our culture is remote-first, self-managed, and we value transparent decision making and an open source ethos.

Our primary project is Fluence, a decentralized serverless platform & computing marketplace powered by blockchain economics. Fluence is a global, permissionless, scalable, and secure alternative to centralized cloud computing platforms. Using Fluence, developers build and deploy applications to a network of compute providers, who compete on price and performance and, to be paid and earn rewards, they constantly prove that they are serving applications.

We are looking for new great additions to the Cloudless Labs core team. We would like to speak to people who are interested in decentralized technology, empathetic, humble, passionate about their work, and strive for excellence. We expect that candidates are experts in their field, keep up to date with recent developments, and are excellent communicators, both in oral and written form.
