Blockchain Security Software Engineer, Hexagate

📋 Description

• • Join Chainalysis Inc. as a Blockchain Security Software Engineer within our innovative Hexagate team, a dynamic group at the forefront of cybersecurity for blockchain and Web3 assets.
• • This role is pivotal in safeguarding digital assets by operating at the critical intersection of cybersecurity and blockchain technology, an environment characterized by constant adversarial threats and the imperative for rapid response.
• • You will be instrumental in developing and deploying a cutting-edge, real-time on-chain detection and response platform.
• • This platform leverages advanced techniques including Machine Learning (ML)-driven threat intelligence, sophisticated custom detection mechanisms, and a powerful Large Language Model (LLM)-powered rules engine to provide robust protection for on-chain assets.
• • Your primary responsibility will be to "track real threats," which involves meticulously analyzing active attack patterns. This includes understanding and dissecting various malicious activities such as wallet compromises, sophisticated money laundering flows, phishing-driven asset drains, and interactions with malicious smart contracts.
• • A core function of your role will be to "build detections." This entails translating observed attacker behaviors and threat intelligence into actionable monitors using our proprietary internal monitoring language (DSL), heuristic analysis, and signals derived from ML models.
• • You will be responsible for "validate and tune" these detections. This critical step involves rigorously measuring their precision and recall, actively working to minimize false positives, and continuously hardening the detections to prevent sophisticated evasion tactics by attackers.
• • The ability to "operationalize fast" is paramount. You will collaborate closely with fellow engineers to ensure that newly developed detections are shipped into production safely and efficiently, encompassing thorough testing, controlled rollout strategies, vigilant monitoring, and the capability for swift rollback if necessary.
• • You will "drive coverage" by proactively identifying gaps in our existing detection capabilities. This involves proposing new signal sources, expanding detection logic to encompass a wider range of blockchains and digital assets, and ensuring comprehensive protection across the evolving blockchain landscape.
• • "Partner closely" with product managers and other engineering teams to ensure that our detection strategies are tightly aligned with customer workflows and response actions, providing maximum value and utility.
• • This role offers a unique opportunity to work on challenging, impactful problems in a rapidly evolving industry, contributing directly to the security and trustworthiness of the cryptocurrency ecosystem.
• • You will be part of a global organization with teams across Denmark, the UK, Canada, the USA, and Israel, collaborating with exceptionally talented individuals who are passionate about solving complex technical challenges.
• • The engineering team is driven by a passion for tackling the hardest technical problems and building products that foster trust in cryptocurrencies.
• • You will contribute to creating user-facing products that are supported by a flexible and scalable data platform, enabling the company to adapt quickly to industry changes and deliver continuous value to customers.
• • The Hexagate team specifically focuses on building cybersecurity products that protect on-chain and Web3 assets, operating in an adversarial space where constant vigilance and swift action are essential.
• • You will gain deep insights into the mechanics of blockchain transactions, token standards, address behavior, bridge functionalities, and concepts like MEV and mempool dynamics, as well as common attacker playbooks.
• • The role requires a strong aptitude for reasoning about evasive behaviors and translating abstract threat narratives into concrete, implementable detection rules.
• • You will be at the forefront of developing real-time threat intelligence and response capabilities within the blockchain security domain.
• • This position demands a blend of deep technical expertise in software engineering, a keen understanding of cybersecurity principles, and a specialized knowledge of blockchain technology.
• • The opportunity to influence the direction of blockchain security tooling and contribute to a safer digital asset ecosystem is significant.
• • You will be empowered to take ownership of your work, from initial threat analysis to production deployment and ongoing refinement.
• • The collaborative environment encourages knowledge sharing and continuous learning, fostering professional growth and development.
• • Your contributions will directly impact the security posture of numerous organizations and individuals utilizing blockchain technology worldwide.
• • This role is ideal for a proactive and analytical individual who thrives in a fast-paced, challenging, and intellectually stimulating environment.
• • You will be working with a modern technology stack, including Python, Rust, Go, Kubernetes, AWS, and real-time streaming technologies, providing ample opportunities to expand your technical skillset.
• • The company's mission to build trust in cryptocurrencies is a powerful motivator, and this role is central to achieving that mission through robust security engineering.
• • You will be part of a company that values diversity and inclusion, fostering a supportive and collaborative work environment.
• • The opportunity to shape the future of blockchain security is immense, making this a truly exciting and rewarding career move.
