We are looking for a Senior Engineer to build and scale security infrastructure for our Transaction Threat Protection team, protecting customer transactions in real time.
This role sits at the intersection of high-volume transaction security and decentralized finance (DeFi), requiring an engineer who balances deep technical execution with a strong product mindset.
What Youll Do:
Systems Architecture: Design and maintain scalable, secure cloud infrastructure capable of processing high-velocity financial data.
Security Engineering: Develop automated systems to detect and mitigate threats within both traditional payment flows and DeFi protocols (Smart Contracts/Web3).
AI-Augmented Development: Integrate the latest AI tools (e.g., Claude Code, Cursor, Copilot, LLM-based analysis) into your workflow to increase engineering velocity and security coverage.
Product Ownership: Partner with product teams to ensure security features provide a seamless user experience without compromising safety.
