Job Description & How to Apply Below
- 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-style workflows, institutional transaction authorization, wallet integration, and node connectivity.
- 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.
- Support address or account registration, transaction limits, allow lists, signing policies, approval workflows, an operational controls.
- 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, Web Socket subscriptions, blockchain event indexing, smart-contract integration, transaction monitoring, and blockchain data models.
- Strong understanding of wallet infrastructure, transaction signing, address management, custody concepts, and key-management patterns.
- Strong backend engineering skills in one or more languages such as Java, Go, Kotlin, Type Script, Rust, Python, or C++.
- Experience with APIs, microservices, event-driven architecture, messaging systems, cloud-native engineering, and production operations.
- Ability to independently own complex engineering problems from design through production delivery.
- Experience with Canton, Daml, validator/participant concepts, DAR deployment, or institutional blockchain workflows.
- Experience with Hyperledger Besu, permissioned EVM networks, or private blockchain deployments.
- Experience with Canton, Daml, validator/participant concepts, DAR deployment, or institutional blockchain workflows.
- Experience with smart-contract audits, fuzz testing, invariant testing, static analysis, formal verification, or secure smart-contract deployment.
- Experience building blockchain indexers, transaction orchestration systems, custody integrations, token lifecycle platforms, or wallet-policy engines.
- Experience with token standards such as ERC-20, ERC-721, ERC-1155, ERC-1400, ERC-3643, or other permissioned-token frameworks.
- Experience building systems in regulated, security-sensitive, or high-value transaction environments.
- Relevant blockchain certifications or training are a plus, including Besu training/certification and Digital Asset Daml/Canton-related certification paths
