ZK Research Engineer (Blockchain - Zones team)

Logos Execution Zone (LEZ) is a programmable blockchain that cleanly separates public and private states while keeping them fully interoperable. Developers can build apps that operate across transparent and privacy-preserving accounts without changing their logic. Privacy is enforced by the protocol itself through zero-knowledge proofs (ZKPs), so it is always available and automatic. 

LEZ aims to deliver full programmability in a hybrid public/private model, with the same flexibility and composability as public blockchains. Developers write and deploy programs in LEZ without addressing privacy concerns. Privacy is protocol-level: programs do not change, accounts are treated uniformly, and private execution works out of the box.

In this role, you will be responsible for actively participating in research, prototyping ideas, transforming research prototypes into production, and conducting code reviews.

Your responsibilities will also include planning, implementing, and shipping end-to-end functionality. As well as profiling bottlenecks, hardening cryptographic components and testing them. 

The candidate should have experience with modern cryptography, familiar with zero-knowledge virtual machines (zkVMs), blockchain or other peer-to-peer systems, and motivated by decentralisation and privacy.

• →Improve existing protocol mechanisms and actively participate in research.
• →Transform research output into production systems.

• Solid Rust knowledge.
• Understanding of cryptography and zk-based blockchain systems.
• Ability to propose improvements to the core protocol. 
• Experience working across different time zones. 
• Strong asynchronous team work.
• Alignment to IFT / Logos values https://logos.co/manifesto.

• Experience with RISC0.
• Participated in building blockchain projects.
• Conducted and implemented core protocol level systems.
• Experience in testing systems and identifying vulnerabilities.
