Java Jobs in Web3

Role Overview

We are seeking a Senior Engineer – Blockchain Platforms to build and integrate the 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. The engineer will collaborate with custody and security teams to ensure blockchain interactions are secure, reliable, observable, and production-ready.

Location – Austin/Dallas/Charlotte/Bay Area

Key Responsibilities

• 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.

Qualifications

• 7+ years of professional software engineering hands-on experience building or integrating blockchain, cryptocurrency, or distributed ledger systems.
