Job Description
Who you are
You have a strong background in blockchain technology and security, with experience in developing monitoring systems that ensure compliance and safety in crypto transactions. Your expertise in Spring Boot allows you to build robust backend systems that can handle complex security requirements. You understand the intricacies of Anti-Money Laundering (AML) regulations and have a keen eye for identifying potential risks associated with blockchain activities.
You are skilled in analyzing hacker addresses and developing algorithms that track malicious activities on-chain. Your familiarity with economic models, particularly MEV (Miner Extractable Value), enables you to simulate attack vectors effectively. You are detail-oriented and have a proactive approach to identifying vulnerabilities in blockchain systems.
You thrive in collaborative environments and enjoy working with financial institutions, blockchain projects, and law enforcement agencies to provide comprehensive security support. Your communication skills allow you to convey complex security concepts to non-technical stakeholders, ensuring everyone understands the importance of security measures.

You will develop algorithms for identifying and tracking on-chain hacker addresses, ensuring that our systems remain secure against potential threats. Your work will involve analyzing risks and providing insights into the security landscape of blockchain transactions.
You will collaborate with cross-functional teams to enhance our blockchain security defense systems, ensuring compliance with AML regulations. Your role will require you to stay updated on the latest trends in blockchain security and adapt our strategies accordingly. You will also conduct thorough analyses of attack vectors, using your knowledge of MEV economic models to simulate potential threats and develop countermeasures.
Your contributions will directly impact the safety and reliability of our services, helping to build trust with our users and institutional partners. You will be expected to document your findings and present them to stakeholders, ensuring transparency in our security practices.
