Senior Software Engineer to own the fiat edge of an institutional blockchain payments network: banking rails, partner integrations, and on/off-ramps between fiat and stablecoins settled on-chain. SWIFT, ACH, or equivalent rails experience required. Blockchain protocol experience a strong plus. Go, Java, or Rust. 5+ years.

The salary range for this role is $120,000 – $240,000 per year.

About Global Settlement

Global Settlement ( globalsettlement.com ) is building institutional-grade blockchain settlement infrastructure that bridges traditional banking and digital markets through stablecoins, commodities, FX, and real-world assets (RWAs). Think the global settlement reach of SWIFT, rebuilt for real-time, regulated digital asset transactions.

The role

You own the fiat side of the network: banking rails, payment integrations, and the connections between traditional finance and settlement on GSX Chain. We are launching banking products on GSX rails with US and cross-border corridors first, and this role exists to make fiat move in and out of the network reliably, compliantly, and at institutional volume.

This is a blockchain payments role. Every rail you integrate terminates in an on-chain settlement event, so you will work with chain finality, stablecoin issuance and redemption, and the settlement protocol every day. Blockchain protocol experience is a big advantage coming in. If you bring deep payments-rails experience without it, expect to build that protocol depth here, fast, because the job requires it.

What you’ll do

• Build and operate integrations with banking partners, payment providers, and custodians: account opening, funding, payout, and FX.
• Own fiat funding and payout flows end to end, including on- and off-ramps between fiat and stablecoins settled on GSX Chain.
• Build the compliance and reporting surfaces those rails require: transaction monitoring hooks, reconciliation, and regulatory reporting.
• Translate between banking operations and chain settlement so a wire on one side and a finalized on-chain transaction on the other are always the same event.
• Design for partner-first launch: abstract provider APIs so we can swap or add rails without rewriting the product.
• Work directly with the ledger and settlement engineers and with partner engineering teams during integration.
• This role is a hands-on coding role with roughly 80% of your time spent coding, 10% of time spent strategizing and coordinating with team members, and 10% of your time spent documenting.

What you bring

• 5+ years of backend engineering, including hands-on payments or core-banking integration work.
• Direct experience with SWIFT, ACH, Fedwire, SEPA, or equivalent rails, and with the reconciliation problems they create.
• Engineering in a regulated environment: you know what KYC, AML, and audit requirements do to a system design.
• Production depth in Go, Java, or Rust, and the flexibility to switch stacks as the roadmap moves.
• Working understanding of blockchain settlement and finality, enough to reason about it when fiat is on the other side, and the drive to go much deeper.
• Startup work ethic and heavy use of productivity and coding tools to multiply your own output and the team’s. You can take a three-bullet brief and execute without hand-holding.
• Blockchain protocol or node infrastructure experience on Ethereum, Cosmos, Hyperledger, Canton, or comparable L1/L2 networks. This is the single biggest differentiator between candidates.
• Stablecoin on/off-ramp, issuance, or FX conversion systems.
• Neobank or banking-as-a-service platform experience, and cross-border payout corridors (US to Africa or LatAm especially).
• CBDC or tokenized-deposit pilot exposure.

Note:

This is a payments engineering role at the boundary between banking rails and on-chain settlement. The core focus is bank, provider, and custodian integrations, fiat funding and payout flows, reconciliation, and the compliance surfaces regulated rails require, each of which terminates in a settlement event on GSX Chain. If you have never integrated a production banking or payment rail, or you are looking for a pure smart contract or application role, this may not be the right fit.

• Ground-floor opportunity to architect settlement infrastructure used by sovereign and enterprise clients
• Direct impact on how digital assets move through the global financial system
• Work at the intersection of blockchain infrastructure, traditional finance, and regulatory innovation
