Blockchain Security Engineer

zeroShadow is a Web3 security company protecting the next generation of decentralised systems through proactive security intelligence and rapid incident response.

We're building tools that help protocols, exchanges, and on-chain organisations prevent attacks before they happen - and react instantly when seconds matter.

zeroShadow is seeking a Blockchain Security Engineer to join our TORCH vSOC team. This exciting role involves an intermediate level of understanding of smart contracts across EVM, Solana, and other ecosystems focused on designing, developing, and implementing blockchain and smart contract (Web3) solutions for zeroShadow's clients. This role involves direct engagement with clients to understand their needs and build tailored capabilities, with a particular emphasis on on-chain asset monitoring and alerting solutions. In the event of an incident, our team will then work closely with the client to analyze and triage attack vectors and contain vulnerabilities in compromised smart contracts.

If you’re excited about empowering a safer Web3 ecosystem, you’ll thrive here.

What You'll Do

• Direct engagement with clients to understand their needs and build tailored capabilities, with a particular emphasis on on-chain asset monitoring and alerting solutions.
• Build custom monitoring across various blockchain analytics tools such as Hypernative, Hexagate, Tenderly, Blockaid and Guardrail.
