About the Role
We are hiring an AI Blockchain Security Engineer for a leading fintech company's security and AI team in the San Francisco Bay Area.
This role focuses on building AI-driven systems for blockchain security research, smart contract analysis, and onchain threat detection. You will work at the intersection of AI agents, blockchain infrastructure, and offensive security to improve automated vulnerability discovery and security investigation workflows across Web3 ecosystems.
Key Responsibilities
Build AI-assisted systems for smart contract security analysis and vulnerability detection.
Research and develop AI agents that analyze smart contracts, protocol logic, and cross-chain transaction flows.
Build internal tooling for automated security investigation, exploit analysis, and threat detection across blockchain ecosystems.
Improve AI reasoning over large codebases, protocol interactions, wallet activity, and complex execution flows.
Collaborate with security researchers, protocol engineers, and infrastructure teams to strengthen security monitoring and incident response.
Stay current with emerging blockchain attack techniques, AI security trends, and evolving Web3 infrastructure.
Requirements
A degree in computer science, artificial intelligence, blockchain, or security.
Experience in one or more of the following:
blockchain security
smart contract auditinView Postingg
vulnerability research
Familiarity with blockchain ecosystems, EVM internals, smart contract execution, and transaction lifecycle analysis.
Understanding of common Web3 attack vectors, including:
reentrancy attacks
access control vulnerabilities
signature replay attacks
oracle manipulation attacks
cross-chain bridge exploits
Familiarity with security practices such as vulnerability analysis, blockchain security monitoring, attack investigation, or exploit validation.
Experience building AI workflows, retrieval systems, tool-calling agents, or LLM-powered security tools.
A strong analytical mindset and a genuine interest in AI-driven security research and blockchain infrastructure.
Preferred
Familiarity with blockchain-related cryptography: hashing, digital signatures, Merkle trees, MPC, or consensus mechanisms.
Work Setup
Full-time, on-site in the San Francisco Bay Area.

Tips for Your Blockchain Engineer Job Search
Tailor your resume to the chain
Hiring managers scan for the specific blockchain network you've built on, whether Ethereum, Solana, Hyperledger, or another. List the chain first, then the layer, then the protocol. Generic blockchain experience without naming the stack gets filtered out fast.
Show audited or deployed contract work
Include links to verified contract addresses on block explorers or to public audit reports. Reviewers distinguish between engineers who wrote contracts in a tutorial and those who shipped production code, so on-chain proof closes that gap immediately.
Filter openings by layer and use case
Roles split sharply between layer-one protocol work, layer-two scaling, DeFi application development, and enterprise permissioned ledgers. Applying to every blockchain opening wastes time. Narrow to the layer you know best so your resume reads as a direct fit.
Apply early to roles that fit
Migrate Mate lists blockchain engineer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Prepare for a live coding whiteboard on Solidity or Rust
Most technical screens test you on gas optimization, reentrancy vulnerabilities, or ownership patterns in real time. Practice writing and explaining these patterns aloud, not just silently, because interviewers want to hear your reasoning as you code.
Negotiate equity vesting with token unlocks in mind
Offers from blockchain-native companies often combine cash, equity, and token grants with separate vesting schedules. Understand when each component unlocks before comparing total compensation, and ask directly whether token grants are subject to cliff periods or clawbacks.
Blockchain Engineer Jobs: Frequently Asked Questions
Which companies are hiring the most blockchain engineers?
The companies hiring the most blockchain engineers right now include MITRE, Mastercard, and Itransition, with the largest share of openings in Virginia, New York, and Texas, based on current listings on Migrate Mate as of November 2026. Demand is concentrated in fintech, enterprise software, and financial services firms building or expanding on-chain infrastructure.
How many blockchain engineer jobs are remote?
About 75% of blockchain engineer openings are fully remote or hybrid as of November 2026, making it one of the more location-flexible engineering disciplines. Smart contract development, protocol research, and DeFi application work tend to be the most remote-friendly sub-areas, while roles involving on-premise enterprise ledger deployments are more likely to require in-person attendance.
How do you become a blockchain engineer?
Start by building a strong foundation in distributed systems, cryptography, and at least one systems programming language such as Rust or Go. Then learn a smart contract language like Solidity by deploying real contracts on a public testnet. Build and publish two or three complete projects, contribute to open-source blockchain repositories to gain peer review, and pursue a recognized credential such as a Certified Blockchain Developer certification to validate your skills to employers.
Can you get a blockchain engineer job with little experience?
You can get hired as a blockchain engineer with limited experience if your portfolio demonstrates working, deployed code rather than just coursework. Build a DeFi protocol clone, a simple NFT contract, or a layer-two bridge on a public testnet and link to verified contract addresses. Many early-career roles in blockchain-native startups prioritize demonstrated curiosity, code quality, and a grasp of security patterns over years on a resume.
What does the blockchain engineer interview process look like?
The process typically opens with a recruiter screen focused on your blockchain background and the specific chains you've worked on. A technical phone screen follows, usually covering smart contract security, gas efficiency, or consensus fundamentals. The final stage is a take-home project or live coding session where you write, deploy, or audit a contract. Some companies add a system design round that tests how you integrate on-chain logic with off-chain infrastructure.
Where can I find and apply to blockchain engineer jobs?
You can find and apply to blockchain engineer jobs on Migrate Mate, which lists current openings from companies across the United States. Search by role, location, or specialization, find the listings that match your background, and apply directly to each one.
