About ArthaNova

ArthaNova is an institutional-grade platform that tokenises real-world credit assets to deliver transparent, programmable liquidity for lenders and investors. Our architecture is blockchain-agnostic with a strong focus on XRPL and interoperability, and our regulatory strategy prioritises the  MAS FinTech Regulatory Sandbox Plus  in Singapore. We operate a hybrid build model : we  rent  non-strategic rails to move fast and  build  patent-capable differentiators.

Growth and Ownership :  Based on the quality of initial delivery, each role includes a pathway for rapid career progression and participation in our  Employee Share Option Plan (ESOP).

Location :  Remote-first (UK / EU / SG time zones preferred)

About the Role

Design, implement, and operate production-grade smart-contract and tokenisation components, and integrate them with secure cloud services and external data sources.

  • Architect and maintain secure cloud infrastructure for blockchain applications (AWS, Azure, or GCP).
  • Implement Infrastructure as Code using Terraform; contribute to robust CI / CD pipelines.
  • Apply security best practice for nodes, keys, wallets, and secrets management.
  • Build and integrate APIs and webhooks to connect on-chain events with off-chain systems.
  • Design data models and use SQL / NoSQL stores for off-chain state and analytics.
  • Conduct code reviews; enforce branching and release discipline with Git.
  • Collaborate with DevOps and Security to meet reliability, performance, and compliance objectives.
  • Track emerging protocols, frameworks, and standards relevant to tokenisation and market infrastructure.

Requirements

  • 5+ years of software engineering, including 3+ years in blockchain development.
  • Strong knowledge of Ethereum / Solidity and at least one of XRPL or Cardano.
  • Proven experience deploying blockchain solutions on AWS, Azure, or GCP.
  • Proficiency with Terraform and Git; solid CI / CD experience.
  • Hands-on integration of APIs, webhooks, and external data feeds.
  • Sound understanding of security principles, cloud IAM, and key management.
  • Competence with SQL (PostgreSQL / MySQL) and NoSQL (MongoDB / DynamoDB).
  • Clear written and verbal communication, with strong documentation practice.

    • Preferred

  • Containerisation and orchestration (Docker, Kubernetes).
  • Experience in DeFi, token standards, or Layer-2 solutions.
  • Observability, monitoring, and logging at scale.

    • What We Offer

  • Competitive compensation.
  • Fast-track progression based on delivery quality.
  • Eligibility for  ESOP  following strong initial performance.
  • Opportunity to shape patent-capable core components.
