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 auditing
- 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.

Get Access To All JobsTips for Finding Visa Sponsorship as a Blockchain Engineer
Map your degree to the role
Blockchain engineering sits at the intersection of software development and cryptography, so your degree field matters. A computer science, mathematics, or electrical engineering degree maps cleanly to the specialty occupation definition USCIS uses to approve H-1B petitions.
Target employers with active LCA filings
Use Migrate Mate to find U.S. employers with verified LCA sponsorship history for engineering roles. Focusing on companies that have already certified blockchain or software engineer positions cuts your research time and signals genuine sponsorship willingness.
Distinguish smart contract from infrastructure work
Employers filing an LCA need to define your role precisely. Smart contract auditing, consensus protocol development, and distributed ledger architecture each map to different job codes, so make sure your offer letter title and duties match what the LCA describes.
Check prevailing wage tiers before negotiating
The DOL requires your offered wage to meet the prevailing wage for your location and role. Run your job title through the OFLC Wage Search before you receive an offer so you know which wage level a compliant employer must meet.
Prepare for specialty occupation RFEs early
USCIS has issued Requests for Evidence on blockchain roles when job duties appear too broad or when the employer can't show a consistent degree requirement for the position. Collect job postings, org charts, and project documentation that demonstrate the role requires a specific bachelor's degree.
Align your portfolio with LCA job categories
Employers in DeFi startups and enterprise blockchain teams often hire under software developer or computer and information research scientist categories. Structure your portfolio and resume around the technical duties that anchor those classifications, not just the word 'blockchain.'
Frequently Asked Questions
Does a Blockchain Engineer role qualify as a specialty occupation for H-1B purposes?
Yes, as long as the position normally requires at least a bachelor's degree in a directly related field such as computer science, software engineering, or mathematics. The key is that the employer must be able to show the specific role requires that degree, not just any bachelor's degree. Roles focused on protocol development, cryptographic system design, or distributed systems architecture typically pass this test.
What degree do I need to get H-1B sponsorship as a Blockchain Engineer?
USCIS looks for a bachelor's degree or higher in a field directly related to the job duties. Computer science, software engineering, information systems, and applied mathematics are the most defensible. Degrees in finance or economics are harder to justify unless the role is squarely in blockchain-based financial systems. If your degree is in a related but adjacent field, strong coursework in cryptography or distributed computing strengthens your petition.
Which visa types can cover Blockchain Engineer sponsorship beyond H-1B?
Australian citizens can use the E-3 visa, which has its own annual cap of 10,500 and no lottery. Chilean nationals may qualify under H-1B1 visa, capped at 1,400 annually, and Singapore nationals under a separate H-1B1 allocation capped at 5,400. All three require a Labor Condition Application and specialty occupation evidence. If you're already working in the U.S. on OPT or STEM OPT, your employer can file while you remain authorized.
Are Blockchain Engineer roles difficult to get sponsored for compared to other software roles?
The specialty occupation bar is the same as for any software engineering position, but blockchain roles face more scrutiny because the job title is newer and some employers haven't yet established internal hiring standards requiring a specific degree. Roles at established fintech firms or enterprise software companies with documented job requirements tend to have smoother LCA and petition processes than early-stage crypto startups.
Where can I find employers actively sponsoring Blockchain Engineer visas?
Migrate Mate lists U.S. employers with verified sponsorship history for engineering roles, searchable by role and city. This lets you focus your applications on companies that have already demonstrated they sponsor visas, rather than finding out late in the process that a company doesn't have an immigration program in place.
What is the prevailing wage requirement for sponsored Blockchain Engineer jobs?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
