Overview:
Role Summary:
Build and integrate the blockchain infrastructure layer that underpins digital asset custody and tokenization platforms. The posting describes this as a hands-on engineering role focused on Layer-1 blockchain integration, core blockchain infrastructure, wallet engineering, and custody-related blockchain workflows.
Key Responsibilities:
• Integrate enterprise systems with existing Layer-1 blockchains and evaluate or extend Layer-1 capabilities to meet custody, scalability, and resiliency needs.
• Engineer for chain-level mechanics such as transaction lifecycle, finality, forks, reorgs, and event propagation, while ensuring blockchain integrations remain reliable under stress conditions and production loads.
• Design and build core blockchain infrastructure services including indexers, event processors, block explorers, observability tooling, chain data services and APIs, and interoperability or cross-chain integration components.
• Build and support wallet architecture, transaction creation and signing workflows, submission pipelines, and integration with custody key management systems such as MPC, HSMs, and signing services.
• Support custody-related blockchain workflows covering on-chain transaction execution, event monitoring and reconciliation, and chain-specific failure handling and recovery patterns.
• Help define safe patterns for interacting with smart contracts and token standards from custody platforms, aligned to custody approvals and risk controls.
• Apply modern engineering practices and AI-augmented development approaches for protocol analysis, code development and testing, documentation, and knowledge sharing.
Source-Supported Qualification Themes
• 7+ years of professional software engineering experience.
• Hands-on experience building or integrating blockchain or distributed ledger systems.
• Strong understanding of Layer-1 blockchain protocols and transaction lifecycles.
• Experience building backend services, APIs, and infrastructure components.
• Proficiency in one or more languages such as Go, Java, Rust, Python, or similar.
• Ability to work effectively across custody, security, and platform teams.
• Strongly preferred: experience with blockchain indexers, explorers, or chain analytics systems; familiarity with wallet architecture and blockchain signing workflows; exposure to crypto custody platforms or security-sensitive financial systems; and experience using AI tooling to support complex software development.
