Job Summary

About the role

  • Integration — Connect the platform to custody providers, wallet infrastructure, node providers and SaaS blockchain platforms; integrate with core banking, payments and ledger systems.
  • Security & resilience — Apply secure coding practices, participate in architecture and threat reviews, and support audit, compliance and production readiness.
  • Collaboration — Work in a cross-functional agile squad with architects, DevOps, security, product owners and blockchain operations; mentor engineers and share knowledge.
