Job description
This is a remote position.
Our client is building the infrastructure that enables humanitarian organizations to use stablecoins without requiring blockchain expertise.
Rather than building another wallet or payment application, we're creating an orchestration layer that connects donors, NGOs, compliance providers, blockchain networks, regulated financial institutions, and local payout providers through a single API.
Blockchain is the infrastructure—not the product.
Our platform orchestrates the complete payment workflow, including:
Funding and treasury management
Compliance and sanctions screening
On-chain transactions
Reporting and audit trails
Beneficiary payouts
Local off-ramp integrations
We integrate best-in-class providers for custody, compliance, blockchain connectivity, and financial settlement instead of replacing existing financial infrastructure.
About the Engagement
This role begins as a project-based contract focused on delivering key milestones for an upcoming pilot.
The initial engagement is deliverables-based, with clearly defined objectives and timelines. Upon successful completion of the pilot and continued platform growth, there is a strong opportunity to transition into a long-term full-time engineering role.
You'll work directly with the founding team and Technical Lead, helping shape the architecture and technical direction of the platform.
