About the Role

About us

BlockchainUnmasked is revolutionizing cryptocurrency forensic investigations through advanced automation, data ingestion, and digestion technologies, combined with cutting-edge security solutions. Our flagship product, Sherlock, is a powerful platform designed for real-time tracking, tracing, and analysis of crypto crimes, dramatically accelerating investigation times to boost success rates in interdiction, recovery, and prevention. We also pioneer ultra-secure wallets and hardware tokens with quantum-resistant technology. We’re looking for an experienced Smart Contract Developer to help build the next generation of secure blockchain infrastructure, enhance forensic capabilities, and ensure airtight security in decentralized environments.


Role overview

As a Smart Contract Developer, you’ll design, develop, audit, and optimize smart contracts that integrate with our AI-driven forensic analysis platform and our secure crypto wallet and hardware token. You’ll work closely with blockchain architects, cryptographers, and security experts to build robust, gas-efficient, and attack-resistant smart contracts.


Key responsibilities

  • Design, develop, and deploy secure and efficient smart contracts on Ethereum, Bitcoin L2s, Solana, or other relevant blockchains.

  • Collaborate with forensic engineers to integrate on-chain transaction tracing and investigative tooling.

  • Implement multi-signature, threshold cryptography, and secure key management mechanisms within smart contracts.

  • Develop and optimize zero-knowledge proofs (ZKPs), MPC, and privacy-enhancing cryptographic techniques where needed.

  • Conduct formal verification, fuzz testing, and security audits to identify and mitigate vulnerabilities.

  • Ensure cross-chain interoperability and work on bridging protocols where necessary.

  • Work on automated alerting and enforcement mechanisms, enabling law enforcement to freeze or track illicit assets in real time.

  • Document and maintain clean, well-structured, and auditable code that meets compliance and forensic standards.
