role overview

We are looking for a curious, open-minded software engineer with a passion for building quality production systems software. Research is an important component of what we do, however, our passion is to change the world by shipping great software.


  • Designing APIs for cryptographic libraries that are easy to use and hard to misuse 
  • Implement cryptographic tools and algorithms 
  • Signature schemes, including multi and threshold signatures
  • Distributed key generation algorithms
  • Merkle trees
  • Encryption schemes
  • Zero-knowledge proofs
  • Key management
  • Authentication mechanisms and securing data in flight and at rest
  • Ensuring secure coding practices and compatibility with client-based applications (browsers, Ledger devices, etc.)
  • Help us change the world


  • Have a good understanding and experience in using cryptographic protocols (encryption and signature schemes, zero-knowledge proofs, etc.)
  • Have previous experience in systems security and implementation best practices
  • Have experience in implementing cryptographic primitives and using hardware/trusted execution environments (smart-cards, HSM, SGX, SEV, etc.)
  • Have a deep understanding of at least one of the following languages: C, C++, Rust or Go
  • Have experience in deploying systems that run 24x7x365. Building the monitoring, alarming, and tooling required to keep them healthy
  • Have a Bachelor's degree in Computer Science, or a closely related field. The unique challenges at Elrond have attracted many engineers with advanced degrees, however, your practical experience is more important to us than your educational background

culture & perks

  • Flexible working hours
  • Start-up atmosphere where everybody is agile without being AGILE
  • The opportunity to create something really meaningful that will be used by millions of people
  • Competitive salary
  • Fast, dynamic & unique working environment

about us

Elrond is a distributed transactional computation protocol which relies on a sharded state architecture and a secure Proof of Stake consensus mechanism. While most other blockchain networks require custom hardware and high energy consumption, Elrond runs on average computers.

By employing sharding, a method of parallelizing data & transactions processing, Elrond’s performance will scale up with the number of computers joining the network, reaching more than 100.000 transactions per second while growing increasingly decentralized.

Elrond represents a highly scalable, fast and secure blockchain platform for distributed apps, enterprise use cases and the new internet economy.

We think every successful initiative is the result of a tremendous team effort from a passionate, focused, and forward-thinking group of individuals.
