Architect Crypto Digital Asset Custody & Blockchain Platforms

Job Title: Architect Crypto Digital Asset Custody & Blockchain Platforms Job Summary Experience: 12+ years preferred We are hiring an Architect Digital Asset Custody & Blockchain Platforms to define and lead the technical architecture for digital asset custody, tokenization, blockchain infrastructure, wallet services, cryptographic key management, and resilient custody workflows. This is a senior hands‑on architecture role operating across blockchain platforms, secure distributed systems, HSM/MPC‑based key management, custody policy controls, and production‑grade operational resilience. Key Responsibilities Define end‑to‑end architecture for digital asset custody platforms across wallets, blockchains, environments, policy systems, and operational workflows. Lead architecture for Layer 1 blockchain integrations, transaction lifecycle handling, finality, forks, reorgs, event propagation, and chain‑specific recovery patterns. Architect blockchain infrastructure services including indexers, event processors, chain data APIs, observability tooling, and interoperability components. Design institutional‑grade key management solutions using HSMs, MPC, secure key generation, storage, rotation, signing, recovery, and backup patterns. Define wallet architecture for transaction creation, signing workflows, submission pipelines, smart contract interaction, and token standard support. Lead architecture for a custody policy engine covering authorization, approvals, limits, segregation of duties, exception handling, auditability, and enforceability. Establish disaster recovery and incident response architecture for key recovery, quorum loss, chain events, custody failures, and operational recovery. Provide technical leadership across engineering, security, risk, operations, SRE, architecture, and leadership stakeholders. Use GenAI and agentic AI tools to accelerate architecture design, threat modeling, protocol analysis, testing, documentation, and reviews while maintaining engineering rigor. Required Qualifications 12+ years of experience in software engineering, platform engineering, secure systems engineering, or architecture. Strong experience designing secure, scalable, observable, and fault‑tolerant distributed systems. Hands‑on experience with blockchain or distributed ledger platforms, especially Layer 1 protocols and transaction lifecycles. Experience architecting backend services, APIs, data pipelines, blockchain infrastructure, and observability components. Deep understanding of cryptographic systems, secure key management, HSMs, MPC, signing workflows, and custody‑grade controls. Experience with wallet architecture, custody workflows, transaction controls, and secure blockchain transaction processing. Strong understanding of resilience, disaster recovery, incident response, operational risk, and audit‑ready system design. Programming experience in one or more languages such as Go, Java, Rust, Python, C, or C++. Ability to influence technical direction and communicate risk‑based architecture trade‑offs to technical and non‑technical stakeholders. Preferred Qualifications Experience with crypto custody platforms, digital asset platforms, tokenization platforms, or blockchain infrastructure. Experience with blockchain indexers, explorers, chain analytics, event processing, and reconciliation systems. Familiarity with Web3 security tooling such as Slither, Mythril, and Foundry Fuzzing. Experience collaborating with security auditors such as Trail of Bits, Halborn, or similar firms. Prior ownership of disaster recovery design, security runbooks, incident response processes, or post‑incident remediation. Experience applying AI tools to architecture, engineering, documentation, testing, and review workflows.
