You will prevent funds loss or state corruption by identifying edge cases in distributed systems.</li><li>Hardened Infrastructure: Architect and secure our cloud-native footprint (AWS/GCP), ensuring that validator nodes, signing services, and P2P networking are resilient against both traditional DDoS and protocol-specific eclipse attacks.</li><li>Application &amp; Lifecycle Security: Build and maintain the Secure SDLC for our products. This includes automated security analysis (SAST/DAST) in CI/CD, managing high-stakes bug bounties, and performing manual penetration tests on our financial APIs.</li><li>Cryptographic Operations: Design and manage mission-critical Key Management Systems (KMS). You will lead the implementation of Multi-Party Computation (MPC), Threshold Signatures (TSS), and HSM integrations to secure private keys at scale.</li><li>Detection &amp; Response: Develop specialized monitoring for both Cyber threats (unauthorized access, lateral movement) and On-chain threats (channel jamming, fee-siphoning, or routing anomalies).</li><li>Security Expert: Serve as the subject matter expert for engineering teams, bridging the gap between standard web security and crypto-native security</li></ul><h2>WHAT WE ARE LOOKING FOR:</h2><ul style="min-height:1.5em"><li>Experience: 6+ years in Security Engineering with a proven track record that spans Infrastructure, Application Security, and Blockchain/DeFi.</li><li>Crypto Understanding: Hands-on experience with cryptographic primitives (Elliptic Curve, Schnorr, Merkle Trees) and a fundamental understanding of Layer 2 scaling (Lightning Network).</li><li>Systems Programming: High proficiency in Python, Rust or Go. You should be capable of auditing systems-level code for memory safety, race conditions, and cryptographic flaws.</li><li>Adversarial Expertise: A history of identifying vulnerabilities in decentralized protocols or high-scale distributed systems. You think three steps ahead of the attacker.</li><li>Compliance &amp; Frameworks: Understanding of how to apply traditional frameworks (NIST, OWASP) to the non-traditional world of decentralized finance and self-custody.</li><li>Education: A CS degree is ideal, but we also value contributions to open-source security tools or a history of disclosed vulnerabilities in the crypto space.</li><li>Communication: Ability to translate complex cryptographic risks into actionable engineering requirements for non-security peers.</li></ul>Lightspark is on a mission to build an open payment protocol for the Internet at scale and therefore we’re committed to creating a more inclusive and diverse workplace to reflect the customers we serve.
