Top Tech Jobs & Startup Jobs in Seattle, WA

Design and develop tools for verifying the correctness of smart contracts, extend verification algorithms, and collaborate with engineers on technical solutions.

Join a security research team to develop analysis tools, review sandbox/VM and network modules, discover vulnerabilities and create PoC exploits for distributed systems, and publish findings. Research areas include malware analysis, vulnerability detection, network anomaly detection, mobile app analysis, reverse engineering, and fraud detection.

Design and implement frontend components for the Solidity compiler, optimize performance, develop integration layers, and collaborate with researchers to enhance security features.

Lead and perform application and network penetration tests, source code and cloud security reviews, and produce clear pentest reports. Research and develop pentesting tools/methods for blockchain and Web3, contribute to community content, and support client security engagements.

Serve as a public-facing Web3 security researcher: engage the community via social media, speak at conferences, give interviews, collaborate cross-functionally with CertiK teams, and support marketing and product feedback while performing technical Web3 security work.

Develop and optimize LLM-driven AI agents to automate smart contract security audits. Collaborate with blockchain security teams to research, prototype, and productionize threat detection, risk assessment, and automated vulnerability analysis for blockchain environments.

Perform smart contract and protocol audits, consult with external blockchain teams on remediation, conduct security research, and build internal security tools and methodologies to protect Web3 projects and clients.

Perform end-to-end blockchain security services including consulting, manual code reviews and audits of smart contracts and protocols (Solidity, Go, Rust), threat modeling, property-based and gas-related testing, penetration testing, and deliver detailed security assessments to clients.

Perform smart contract and blockchain audits to find and analyze vulnerabilities, define attack models, extract exploit characteristics to build feature-analysis tooling, and research/adopt analysis tools and emerging blockchain security technologies.

Perform guided audits of smart contracts, blockchain protocols, and dApps to identify and remediate vulnerabilities. Contribute to security tooling and research, explore attack vectors, and support process and methodology improvements under senior guidance.
