Senior Backend / Blockchain Engineer
Employment Type: Full-time | Location: Singapore, Indonesia, Malaysia
Job Description
Hydra X is building institutional-grade infrastructure across custody, exchange, tokenisation and digital asset networks.
We are looking for a Senior Backend / Blockchain Engineer with strong Web2 engineering fundamentals and practical experience, or strong interest, in blockchain and distributed ledger technologies.
A key priority workstream may involve the Canton Network, including applications for institutional asset issuance, settlement and transaction workflows. However, this is not a Canton-only role. The engineer should also be able to contribute to Hydra X’s broader products across custody, exchange, tokenisation and digital asset infrastructure.
Experience with Canton or DAML is a strong plus, but not mandatory. We are looking for someone with strong backend capability, blockchain familiarity and the ability to learn new technologies quickly.
Responsibilities
- Build production-grade backend services and applications for digital asset infrastructure.
- Design APIs, integration layers and services connecting Hydra X products with blockchain networks, distributed ledgers and enterprise systems.
- Support Canton-related workstreams where relevant, including technical exploration, integration design and implementation.
- Work with ledger concepts such as validator interaction, party-to-party workflows, asset issuance, transfers and settlement flows.
- Work with wallets, private keys, signing flows, identity and infrastructure-level authentication where relevant.
- Write unit, integration and end-to-end tests to ensure application logic is reliable and production-ready.
- Collaborate with DevOps on deployment, monitoring, observability and production hardening.
- Work with Product & Technology, Sales Engineering and Client Solutions to translate business and client requirements into technical solutions.
Qualifications & Requirements
Web2 / Backend
- Backend skills
You are comfortable in one or more backend languages such as Python, Go, Java, Kotlin, Scala, TypeScript or Node.js.
- API know-how
You can design and consume REST APIs, and understand authentication, pagination, retries, timeouts, idempotency and error handling.
- Database experience
You are comfortable with relational databases such as PostgreSQL, including schema design, migrations and query performance.
- System design
You understand how to design reliable backend services, integration layers and distributed systems.
- Testing mindset
You write unit, integration and end-to-end tests.
- Tooling
You are comfortable with Git, CI/CD pipelines and modern software development workflows.
Blockchain / Digital Assets
- Blockchain fundamentals
You understand addresses, transactions, smart contracts, consensus, immutability and blockchain network concepts.
- Smart contract or ledger experience
You have worked with, or are willing to learn, technologies such as Solidity, Rust, Hyperledger Fabric, Corda, DAML or similar.
- Wallets and keys
You understand private keys, wallets, signing flows and the security implications of handling digital assets.
- Node and network interaction
You have worked with blockchain nodes, validators or network APIs, or are comfortable learning how they operate.
- Digital asset workflows
You are interested in tokenisation, custody, settlement and institutional digital asset infrastructure.
Canton / DAML
- Canton and DAML
Prior experience is not required, but you should be excited to learn and work with Canton and DAML if relevant projects proceed.
- Institutional DLT workflows
Experience with permissioned networks, privacy-preserving ledgers or regulated financial infrastructure would be highly valuable.
Nice to Have
- Experience in capital markets, custody, exchanges, tokenisation or institutional digital assets.
- Experience working with regulated financial institutions or enterprise clients.
- Experience with Docker, Kubernetes, Helm, cloud environments, Prometheus or Grafana.
- Frontend experience with React, Vue or Angular.
Why Join Us?
- Build real institutional digital asset infrastructure used by regulated financial institutions.
- Work across custody, exchange, tokenisation and emerging digital asset networks.
- Help Hydra X build Canton capability while contributing to broader production systems.
- Join a team where engineering decisions need to balance innovation, security, regulatory expectations and production readiness.
