Job Title::Architect Crypto Digital Asset Custody & Blockchain Platforms
Location: Onshore Austin / Dallas
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.
