• Design and build reusable Web3 platform services for tokenization, transaction processing, blockchain connectivity, wallet integration, event ingestion, indexing, and token lifecycle management.
• Build backend services that interact with blockchain nodes, smart contracts, signing systems, custody platforms, and off-chain systems.
• Develop common blockchain abstraction layers that can support multiple networks, including Besu, Canton, Ethereum/EVM, Layer 2 networks, permissioned chains, and future enterprise blockchain platforms.
• Build integrations with Hyperledger Besu, Ethereum-compatible networks, and permissioned EVM chains.
• Implement blockchain connectivity using JSON-RPC, WebSocket subscriptions, ABI encoding/decoding, event logs, transaction submission, transaction status tracking, and smart-contract queries.
• Support engineering patterns for Canton/Daml-based blockchain networks, including validator or participant connectivity, application package lifecycle, transaction authorization, and workflow integration.
• Work with Daml application concepts, including DAR package deployment, versioning, installation validation, and application enablement.
• Build or integrate services that support Canton->
• Partner with platform, infrastructure, and operations teams to evaluate Canton validator strategies, including self-hosted and provider-operated models where applicable.

Smart Contract & Tokenization Integration Engineering

• Design, develop, integrate, and review smart contracts for tokenized asset and programmable workflow use cases. Support smart-contract security practices, including threat modeling, static analysis, fuzzing, invariant testing, and secure deployment pipelines.
• Integrate with institutional wallet, custody, signing, and authorization platforms that support tokenized asset workflows.
• Design transaction orchestration workflows covering request validation, policy checks, approval routing, signing, submission, confidence tracking, retries, and exception handling.
• Support address or account registration, transaction limits, allowlists, signing policies, approval workflows, and operational controls.

Wallet, Signing & Transaction Orchestration Integration

• 5+ years of software engineering experience building distributed systems, backend platforms, financial systems, blockchain infrastructure, custody platforms, trading systems, or high-scale transaction systems.
• Strong hands-on Web3 engineering experience. Deep understanding of Ethereum/EVM, including smart contracts, ABI encoding, transaction lifecycle, gas/fee handling, nonce management, logs/events, confirmations, and finality.
• Experience building backend services that interact with blockchain nodes, wallets, smart contracts, signing systems, or custody platforms.
• Experience with JSON-RPC, WebSocket subscriptions, blockchain event indexing, smart-contract integration, transaction monitoring, and blockchain data models.
