Key Responsibilities

Design, build, and maintain the core platform and internal tooling that supports zkSync protocol and application development.

Develop high-performance services and infrastructure components for both L1 and L2 systems.

Optimize CI/CD pipelines, testing frameworks, and developer workflows to improve iteration speed and reliability.

Conduct research, prototype solutions, and produce high-quality technical documentation.

Collaborate with Protocol, DevEx, Core Engineering, and Security teams to shape platform architecture and long-term infrastructure roadmap.

Ensure platform components meet high standards of scalability, security, and performance.

Experience with strongly typed languages (Go, Rust, C++, Scala) — Rust experience highly valued.

Familiarity with smart contract development workflows (Foundry, Yul, Solidity tooling) is a strong plus.

Deep experience with CI/CD, observability stacks, release pipelines, and environment orchestration.

Solid understanding of algorithms, data structures, and system performance optimization.

Knowledge of cryptographic primitives, Merkle trees, or low-level protocol components is a bonus.

Core Competencies

Ownership mindset with a history of operating in environments with high technical accountability.

Strong cross-functional communication and the ability to collaborate with protocol and product teams.

Passionate about developer experience, internal tooling excellence, and building leverage for engineering teams.

Curious, proactive, and motivated to push the boundaries of what’s possible in zero-knowledge infrastructure.

Fluent written and spoken English.
