Solidity Engineer, Gateway

Zama’s recently released Zama Confidential Blockchain Protocol enables confidential smart contracts on top of any L1 or L2 using FHE.

This position is within the Zama Gateway team. The Gateway is the central orchestrator within Zama’s FHEVM protocol, coordinating interactions between users, host chains, coprocessors, and the Key Management Service (KMS).

We are seeking a skilled and motivated Solidity Engineer to join our Gateway team, developing the rollup infrastructure that ensures both functional reliability and on-chain security through mechanisms like DAO, multisig, and ownership control built on top of the Ethereum stack — hence, strong familiarity with Ethereum and its ecosystem is essential.

You’ll work shoulder-to-shoulder with a team of esteemed engineers and play a pivotal role in designing, fine-tuning, and ensuring the sustained excellence of Zama’s Confidential Blockchain infrastructure.

Only candidates in the US East Coast or Canada (or more broadly within the Eastern time zone, UTC-5) are eligible.

Responsibilities

• Design, implement, and optimize the smart contracts powering the Gateway’s rollup, ensuring robustness, scalability, and secure integration with Zama’s confidential blockchain protocol

• Apply best practices in blockchain security, including multisig, DAO governance, payment and cross-chain (Layer 0) models.

• Collaborate with engineers, cryptographers, and DevOps to build, review, and deploy reliable on-chain components.

• Contribute to developer documentation, internal tooling, and community support.

• Stay up to date on rollups, Layer 2 scalability, and emerging blockchain protocols.

• Ensure gas efficiency through a deep understanding of calldata, memory, storage, and event trade-offs.
