Remote Smart Building Jobs in Missouri (NOW HIRING)

• Review smart contracts for decentralized applications, blockchain infrastructure, and financial institutions, identifying vulnerabilities, assessing their severity, and clearly presenting findings to clients.
• Lead security audits independently from planning through final delivery, using AI as a primary collaborator and partnering with other researchers when additional attack perspectives are valuable.
• Participate in protocol design reviews, analyzing architecture, trust assumptions, security models, and operational constraints before implementation begins.
• Collaborate directly with protocol engineering teams on co-creative engagements involving research, mechanism design, specification, and smart contract development.
• Design and develop smart contracts as part of research and client engagements, applying strong security and engineering principles throughout the development lifecycle.
• Integrate AI effectively into audit workflows and develop reusable skills, agents, prompts, scripts, and processes that improve team productivity and security coverage.
• Conduct open-ended research into emerging blockchain technologies, vulnerability classes, attack vectors, and novel security mechanisms.
• Document research findings and contribute insights to internal security knowledge bases and the broader blockchain security ecosystem.
• Work closely with clients and fellow researchers to communicate technical risks, security recommendations, and complex findings clearly and effectively.

Requirements:

• Hands-on practical experience in one or more relevant areas, including software development, cybersecurity, applied mathematics, distributed systems, cryptography, cryptoeconomics, game theory, or DeFi mechanisms.
• Proven experience designing and developing smart contracts, in addition to auditing or reviewing them.
• Strong working knowledge of Solidity and the Ethereum/EVM ecosystem, including common libraries, frameworks, and smart contract design patterns.
• Extensive experience using modern AI tooling as part of daily technical work to expand audit coverage, reason through complex systems, and accelerate high-quality security analysis.
• Ability to critically evaluate AI-generated code and outputs rather than relying on them without technical validation.
• Experience building and extending personal or team tooling, including AI skills, agents, prompts, scripts, or complete security workflows.
• Advanced English proficiency with strong written and verbal communication skills.
• Experience with non-EVM ecosystems or blockchain technologies such as Canton, Move, Cosmos SDK/Golang, Cairo, Rust-based blockchains, or zero-knowledge circuits is a plus.
• Experience with crypto risk assessment, smart contract risk analysis, or threat modeling is highly desirable.
• Web2 security experience in areas such as penetration testing, web application security, infrastructure security, or application security is an advantage.
• Knowledge of formal verification, invariant testing, or advanced fuzzing tools such as Echidna, Foundry, Halmos, or Certora is beneficial.
• Experience participating in audit contests or bug bounty platforms, including Code4rena, Sherlock, Cantina, Immunefi, or HackerOne, is a plus.
• A track record of publicly sharing security research through published findings, technical articles, conference presentations, or open-source security tooling is advantageous.

Benefits:

• Fully remote work environment with flexibility across locations.
• Opportunities to meet teammates through company gatherings around the world.
• Flexible time off to support sustainable work and personal needs.
• 8 weeks of paid leave for primary caregivers.
• 4 weeks of paid leave for secondary caregivers.
• One-time $3,600 baby bonus.
• Up to $500 in equipment support to build an ideal home office.
• Medical insurance coverage.
• Learning and development opportunities to support continued professional growth.
• Monthly stipend for a preferred co-working space.
