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.
