Systems Engineer - Rust and Cryptography

NYMRemote

The Nym team is a world-class mix of privacy experts, engineers, and thinkers spread across Europe. We believe that user privacy underpins democratic freedoms in a networked world, and we're proud to help roll back the surveillance society.
Nym is looking for a skilled Rust Engineer with strong open-source exposure to join our Core Development Team, focusing on smart contracts, post-quantum secure networking, and cryptographic systems. This is a key engineering role in a world-class team working on the cutting edge of privacy tech, decentralized networking, and blockchain infrastructure.

🧭 In Your First Month, You Might:


  • Get up to speed with post-quantum security developments at Nym.
  • Write CosmWASM smart contracts.
  • Optimize performance of network tunnel devices in the Nym mixnet to route IP traffic efficiently.
  • Work on Cosmos L1 → L2 migration strategies and integrations with chains like Sui and Walrus.

🎯 Key Responsibilities:


  • Build and maintain advanced privacy-preserving network infrastructure.
  • Develop and audit cryptographic systems, especially around zk-credentials and e-cash.
  • Develop smart contracts for decentralized systems, including CosmWASM and blockchain-specific integrations.
  • Support integrations with wallets, explorers, and external systems.
  • Contribute to browser-ready WebAssembly components.
  • Champion post-quantum secure implementations across the stack.

Must Have:


  • 5+ years in back-end or systems-level engineering.
  • Proficiency in Rust, with strong experience in async programming (e.g., Tokio).
  • Deep knowledge of networking and cryptography.
  • Experience building or scaling distributed systems.
  • Comfort with cryptographic libraries and protocols.

Great to have: 


  • Experience with Cosmos, CosmWASM, and blockchain migrations (e.g., L1 to L2).
  • Familiarity with EVM, blockchain wallets, and smart contract ecosystems.
  • Contributions to open-source cryptography or privacy tech projects.

What we offer you: 


  • A diverse, global team of 50+, interested in learning and solving problems together.
  • 6 Weeks annual leave plus national holidays.
  • Yearly learning and development allowance.
  • IT hardware package tailored to your role.
  • Remote working (with a bias towards being able to do in-person meetups periodically).
  • A competitive salary.
