Blockchain Unmasked is hiring a

Web3 Smart Contract Developer

About Us
BlockchainUnmasked is working to make crypto crime solvable. We aim to streamline cryptocurrency forensic investigations through advanced automation combined with cutting-edge solutions. We work with our investigative partners to dramatically accelerate investigation times and boost success rates in interdiction, recovery, and deterrence.

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.

What We’re Looking For

Must-Have Skills

• 3+ years of experience in smart contract development.

• Proficiency in Solidity, Rust, or Move (depending on target chains).

• Experience with Ethereum (EVM), Bitcoin L2s, Solana, or other blockchains.

• Strong understanding of DeFi protocols, security best practices, and attack vectors (reentrancy, flash loans, etc.).

• Familiarity with cryptographic techniques such as ZKPs, MPC, homomorphic encryption, and key management.

• Ability to work in a fast-paced, security-first, and research-driven environment.

Nice-to-Have Skills

• Experience with cross-chain protocols, bridges, or interoperability frameworks.

• Familiarity with wallet integrations, custody systems, or hardware-backed key management.

• Experience with on-chain forensic analysis and blockchain analytics is a huge plus.

• Experience in formal verification tools like Certora, Slither, or Echidna.
