You’ll be constantly exposed to new concepts, ideas, and frameworks from your peers, and as you work on different projects — challenging you to stay at the top of your game. You’ll join a network of builders that reaches the edge of our ecosystem. Consensys alumni have moved on to become tech entrepreneurs, CEOs, and team leads at tech companies.
What you’ll do
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. As such we work in close collaboration with the prover team and the Besu client team.
We are seeking an experienced Senior Java Software Engineer to contribute to the development of our zkEVM tracer. The ideal candidate will have a strong background in software engineering, specifically in Java, and a passion for blockchain technology. They will contribute to the design, development, and maintenance of the tracer and related components and will work closely with the research team.
Key Responsibilities:
- Design, develop, and maintain the zkEVM tracer.
- Collaborate with the research team to ensure that the tracer accurately implements the zkEVM protocol.
- Work with other teams to integrate the tracer into the existing infrastructure and architecture of Linea.
- Continuously evaluate and improve the performance and scalability of the tracer.
- 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.
- Strong project management skills and ability to work independently and manage multiple projects simultaneously.
- Strong communication and collaboration skills.
- A bachelor's degree in Computer Science or a related field.
- Experience in blockchain development is a plus
- Familiarity with zk-SNARKs or related zero-knowledge proof systems is a plus.
