Deskripsi pekerjaan Senior Backend Engineer PT Hydrax Teknologi Indonesia
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.
What You’ll Do
- 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.
Technical 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.
