About This Role
This engineering role focuses on designing and building reusable Web3 platform services for tokenization, transaction processing, blockchain connectivity, wallet integration, event ingestion, indexing, and token lifecycle management. It involves developing backend services that interact with various blockchain components and establishing engineering standards for smart contract development and security practices.
Responsibilities
- 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, Web Socket 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
- Design, develop, integrate, and review smart contracts for tokenized asset and programmable workflow use cases
- Work with Solidity, EVM token standards, upgradeable contracts, proxy patterns, access-control models, permissioned-token designs, and contract event models
- Build smart-contract interaction layers that manage ABI encoding, calldata construction, transaction simulation, event decoding, and contract state reads
- Establish engineering standards for smart-contract development, testing, deployment, versioning, rollback planning, and production change governance
- 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, confirmation tracking, retries, exception handling, and audit logging
