Job title: Blockchain and Web3 Security Auditor
Job type: Full-time employment
Location: Paris, Rennes, Buenos Aires OR Remote
Are you fascinated by the new possibilities offered by the Blockchain and Web3? Do you want to bring your experience and creativity into this world to help secure this area? Do you want to experience what is being done at the forefront of the field? If yes, we are looking for you!
Within the Quarkslab Lab, you will participate in the expansion of our activities related to blockchain technologies, that we started in 2018. Specifically, Quarkslab specializes in wallet and infrastructure security audits.
By relying on the different expertise of our project manager and engineers, for example in cryptography or fuzzing, you will participate in software based security evaluations of whole ecosystems, not only smart contracts. You'll be working with a team in source code reviews that will require that you deep dive into several blockchain technologies, grasp the code architecture, and finally look for logic security vulnerabilities that could lead to DoS or double spending.
We are looking for a curious person interested in taking up new challenges and investigating new categories of security vulnerabilities. At Quarkslab, we enjoy writing tools and perform research to smooth our audit activities and get better results. Within this role, you will have the opportunity to work on R&D projects in which you will step up and define new methodologies and tools to facilitate blockchain vulnerability research, and to share your knowledge in conferences.
Prior knowledge of blockchain ecosystems is not mandatory, as long as you are a fast learner and willing to discover new languages, such as Rust, Go, and frameworks. Some experiences in source code auditing is obviously important, but that is something that you can definitely learn with us!
Still interested? Do not waste more time and apply today.
