Janus is building the financial operating system for global freight: AI-powered freight document intelligence (live in production with paying customers), stablecoin-powered same-day settlement, and shipment-data-underwritten working capital. Freight forwarders pre-finance shipments, wait 30-90 days to get paid, and settle cross-border through correspondent banking that costs 2-4% and takes days to clear. We fix that in layers - documents, then payments, then credit.
We're looking for a hands-on blockchain engineer to own our on-chain and fintech integrations as we move from documents into payments and credit. This is not a protocol-research role - it's a shipping role. You'll stitch together stablecoin rails, on/off-ramps, yield products, lending infrastructure, and compliance tooling into a coherent banking product for freight forwarders, across multiple chains.
Engagement
- Contractor, full-time: August - December 2026 (approx. 4 months)

What You'll Build
Payments Orchestration
- Design and build our routing proxy across multiple money orchestrators and stablecoin on/off-ramp providers, so every customer payment automatically gets the best rate, corridor, and settlement speed
- Own the architecture decisions for how cross-border settlement flows through the platform
Yield Generation & Curated Vaults
- Integrate tokenized yield sources (tokenized treasuries and other real-world assets) so idle customer balances earn yield natively in the product
- Build curated vaults we manage on behalf of customers - segregated, compliance-friendly vault structures holding real-world assets
Lending & Receivables
- Help tokenize shipment documents and receivables and share them with lenders and asset platforms on our platform
