Senior Software Engineer - Cryptography

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.

responsibilities

• 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

requirements

• 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

• 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.
