Senior Onchain Investigator

As a Senior Onchain Investigator at Coinbase, you own end-to-end onchain investigations into threat actors targeting Coinbase and the crypto ecosystem. You'll cluster illicit wallets, fuse OSINT with onchain evidence, and turn findings into detections, blocks, and decisions that protect customers and products. This role leads investigation methodology for the team, not just individual cases.

What you'll do

• Own complex onchain investigations into threat actor infrastructure, scam networks, exploits, and related abuse targeting Coinbase and Base
• Drive clustering and attribution of illicit actors using blockchain analytics, OSINT, and internal data, then operationalize results into Vertex Synapse and downstream controls
• Build OSINT and onchain analysis pipelines, queries, and dashboards that automate detections and scale investigative capacity across the team
• Lead post-incident reviews and root cause analyses to identify gaps and recommend enhancements to controls, detection, and overall security posture
• Partner with product, engineering, and risk teams to embed threat and abuse mitigation strategies into the product development lifecycle from ideation to launch
• Lead new investigative techniques, teach them across Security, and brief executives with clear risk, impact, and recommended actions

What you bring

• 5+ years of investigations, including 3+ years investigating onchain illicit activity, cryptocurrency abuse, or blockchain intelligence, with a track record of independently leading investigations from collection through stakeholder action
• Deep knowledge of blockchain ecosystems and protocols, including tracing across chains, bridges, mixers, and laundering patterns
• Proficiency with Python or Go and SQL for data analysis, scripting, or tooling development in support of intelligence workflows and automation
• A track record of creating investigation methods, dashboards, or pipelines that other investigators adopt
• Proven ability to translate complex technical analysis into clear, actionable intelligence for both technical and non-technical stakeholders, including executive briefings
• Skilled in conducting open-source intelligence (OSINT) research across a wide range of topics
• Ability to utilize generative AI responsibly, maintaining human oversight to deliver business-ready outputs and drive measurable improvements in workflow efficiency, cost, and quality

What we offer

• Annual base salary of $180,370 USD to $212,200 USD, varying by location
• Equity and bonus eligibility
• Benefits including medical, dental, vision, and 401(k)
