Job Title: Blockchain Architect Zero-Knowledge Proof (zk-SNARKs) Specialist

Job Type: Contract

Senior Level Experience Required:

15+ years in software development, 10+ years in blockchain technologies, 5+ years with zero- knowledge proofs

Job Summary:

We are seeking a highly experienced Blockchain Architect with deep expertise in Zero- Knowledge Proofs (zk-SNARKs) and other privacy-enhancing technologies. The ideal candidate will be responsible for designing and implementing advanced blockchain solutions with a strong focus on privacy, scalability, and regulatory compliance. This role requires hands- on experience with zk-proof development frameworks (e.g., Circom, SnarkJS, ZoKrates), smart contract engineering, and decentralized identity systems. You will lead architecture and implementation initiatives across enterprise-grade blockchain platforms such as Ethereum, Hyperledger Fabric, and Polkadot.

Key Responsibilities:

  • Architect and implement secure, scalable, and privacy-preserving blockchain solutions using zk-SNARKs and related technologies.
  • Lead the development of zk-rollups, confidential tokenization platforms, and decentralized identity (DID) systems.
  • Work with cross-functional teams to integrate zero-knowledge proofs into enterprise- grade blockchain stacks.
  • Guide development teams on best practices for zero-knowledge cryptography, including trusted setup, Groth16, and PLONK proving systems.
  • Collaborate with research and innovation teams to prototype and test cutting-edge cryptographic protocols.
  • Conduct security reviews and smart contract audits for privacy-preserving applications.
  • Interface with clients to gather technical requirements, propose solutions, and deliver end-to-end blockchain architecture.
  • Mentor junior engineers and contribute to internal knowledge sharing on zk technologies. Required Skills & Qualifications:
  • Proven experience in zero-knowledge proof systems: zk-SNARKs, zk-STARKs, Bulletproofs, zk-rollups.
  • Hands-on expertise with Circom, ZoKrates, SnarkJS, Groth16, and PLONK.
  • Deep understanding of Ethereum, Hyperledger Fabric, Polkadot, and other Layer 1/Layer 2 blockchain platforms.
  • Strong programming skills in Solidity, Rust, Go, Python, and JavaScript.
  • Experience with DeFi protocols, tokenization, and privacy layers (e.g., zkSync, Mina, Tornado Cash).
  • Strong grasp of cryptographic data structures like Merkle Trees and secure hashing algorithms.
  • Proficient in cloud platforms and DevOps tools: AWS, Azure, Docker, Kubernetes, GitHub Actions.
  • Familiarity with DID systems and privacy regulations (GDPR, HIPAA).
  • Excellent problem-solving, communication, and project leadership skills.
  • Note
