The arithmetization team provides the constraint system underlying Linea’s zkEVM and the execution traces built by the (zkevm) tracer. Traces are generated by hooking into the Besu execution client and are, along with constraints, the inputs for producing zero knowledge proofs of EVM execution.

- Participate in code reviews and ensure the codebase adheres to best practices and standards.
- Participate in the design and implementation of advanced “edge case” tests of the arithmetization.
- Documenting and providing support to the tracer users.
Qualifications:
- Strong background in software engineering, specifically in Java.
- Experience leading the development of a project from start to finish.
- Strong understanding of blockchain technology and the zkEVM layer 2 protocol.
- Strong problem-solving skills and ability to think creatively.
