About the company
Join a globally distributed security research team dedicated to protecting the next generation of blockchain applications and digital financial infrastructure. You will help secure decentralized applications, smart contracts, and onchain financial systems used by leading organizations worldwide.
Responsibilities
- Conduct comprehensive security audits of smart contracts used by decentralized applications, blockchain infrastructure, and financial institutions.
- Lead security audits independently from planning through final reporting, using AI as a core research collaborator.
- Participate in protocol design reviews and applied research engagements, evaluating system architecture, trust assumptions, threat models, and operational constraints.
- Collaborate with client engineering teams to analyze, design, specify, and improve smart contract mechanisms and security-critical protocol components.
- Integrate AI tools throughout the audit lifecycle to improve coverage and accelerate complex reasoning.
- Develop and maintain reusable security tooling, including AI agents, prompts, scripts, and automated workflows.
- Investigate emerging blockchain technologies, vulnerability classes, exploit techniques, and attack vectors.
- Document research findings and communicate technical risks clearly to clients.
- Continuously refine audit methodologies and research practices.
Requirements
- Practical experience in one or more relevant technical fields, including software development, cybersecurity, applied mathematics, distributed systems, cryptography, cryptoeconomics, game theory, or decentralized finance mechanisms.
- Hands-on experience designing and developing smart contracts.
- Strong working knowledge of Solidity and the Ethereum Virtual Machine (EVM) ecosystem, including common libraries, development frameworks, smart contract patterns, and protocol architectures.
- Regular, effective use of modern AI tools to improve security audits.
- Ability to critically evaluate AI-generated code and findings.
- Experience building or extending technical tools and workflows, such as custom scripts, prompts, AI agents, and reusable automation.
- Advanced English proficiency.
Nice to Have
- Experience with non-EVM blockchain ecosystems and programming languages, such as Canton, Move for Sui or Aptos, Go for the Cosmos SDK, Cairo for Starknet, Rust-based blockchains such as Solana or Stellar, or zero-knowledge circuits.
- Experience in crypto risk assessment, smart contract threat modeling, or evaluating the security of decentralized financial protocols.
- Experience collaborating directly with protocol teams on co-creative engagements.
- Background in Web2 security, including penetration testing, web application security, infrastructure security, or application security.
- Familiarity with formal verification, invariant testing, and advanced fuzzing tools such as Echidna, Foundry, Halmos, or Certora.
- Demonstrated participation in smart contract audit contests, such as Code4rena, Sherlock, or Cantina, or bug bounty platforms such as Immunefi or HackerOne.
- A portfolio of public security research.
Conditions
- Fully remote work with flexibility to work from anywhere.
- Flexible time off.
- Opportunities to meet teammates through company gatherings around the world.
- Eight weeks of paid leave for primary caregivers and four weeks for secondary caregivers.
- A one-time baby bonus of $3,600.
- Up to $500 in equipment support.
- Medical insurance coverage.
- Learning and professional development opportunities.
- A monthly stipend for a preferred coworking space.
