Senior Engineer – Blockchain Platforms

As a Senior Engineer - Blockchain Platforms at Core AI Consulting, you build and integrate blockchain infrastructure supporting digital asset custody and tokenization platforms. This hands-on role focuses on Layer-1 blockchain integration, core infrastructure services, wallet engineering, and custody-related blockchain workflows. You collaborate with custody and security teams to ensure blockchain interactions are secure, reliable, observable, and production-ready.

What you'll do

• Integrate enterprise platforms with Layer-1 blockchains and evaluate protocols based on custody, scalability, security, and resilience requirements
• Design and build blockchain infrastructure services, including indexers, event processors, chain-data APIs, observability tools, and cross-chain components
• Develop wallet services and transaction pipelines covering transaction creation, signing, submission, monitoring, and reconciliation
• Integrate wallet services with MPC, HSM, key management, and signing platforms
• Design for chain-specific conditions such as finality, forks, reorganizations, network congestion, and transaction failures
• Develop safe patterns for interacting with smart contracts, token standards, and blockchain networks
• Ensure blockchain data pipelines and services are accurate, scalable, testable, observable, and auditable
• Support troubleshooting, incident response, failure recovery, and root-cause analysis across distributed blockchain environments
• Use generative and agentic AI tools to accelerate protocol analysis, development, testing, documentation, and knowledge sharing

What you bring

• 7+ years of professional software engineering experience building or integrating blockchain, cryptocurrency, or distributed ledger systems
• Strong understanding of Layer-1 protocols, transaction lifecycles, finality, forks, reorganizations, and event propagation
• Proficiency developing backend services, APIs, event-driven systems, and infrastructure components
• Proficiency with blockchain indexers, explorers, chain analytics, or on-chain data platforms
• Proficiency in wallet architecture, transaction signing, and blockchain submission workflows
• Strong experience with smart contracts, token standards, and cross-chain interoperability
• Proficiency integrating with MPC, HSM, key management, or digital asset custody platforms
• Strong troubleshooting skills in distributed, asynchronous, and security-sensitive environments
• Ability to collaborate effectively across engineering, custody, cybersecurity, risk, and platform teams
• Strong experience in Go, Java, Rust, Python, or a comparable programming language

Nice to have

• Experience using generative or agentic AI tools to support complex software engineering workflows
