Industries / Fintech
Engineers who understand flow of funds, compliance, and the real cost of getting it wrong.
The reality on the ground
Compliance velocity vs. product velocity.
Every feature touches audit scope. You need engineers who ship without forcing a SOC 2 rewrite.
Sponsor bank timelines.
BaaS contracts don't care about your sprint. Integration quality shows up in month-end reconciliation.
Ledger integrity at scale.
One off-by-one in reconciliation and finance spends the week in spreadsheets.
Where we plug in
Our engineers have shipped production code against sponsor banks, processors, card programs, and crypto rails. They understand double-entry, idempotency, and why a retry queue matters more than a feature flag.
Payments & rails
ACH, wires, RTP, FedNow, local rails. Integrations with processors, not just webhooks.
Ledger & reconciliation
Double-entry accounting systems, journal engines, flow-of-funds modeling.
BaaS & card programs
Treasury Prime, Direct-to-bank, Lithic, Marqueta. Issuing, authorization flows, settlement.
Stablecoin rails
USDC/USDT on/off-ramps, cross-border, custody, wallets. Treasury flows across on-chain and fiat.
Industry fluency
Not keywords on a résumé — systems, standards, and vendors our engineers have worked inside of in production.
Rails & programs
Processors & cores
Compliance
Crypto & stablecoins
What we've shipped

Roles we staff most
Ledger & backend engineers
Double-entry, idempotency, reconciliation at scale.
Payments integration devs
Processor APIs, webhooks, retry queues, sandbox-to-prod parity.
Fraud & risk engineers
Rules engines, signal ingestion, decisioning pipelines.
Core banking integration leads
FIS / Fiserv, file-based workflows, ISO 20022 migrations.
The bar we hold
SOC 2–aware from day one.
Audit-trail logging, least-privilege access, evidence-ready change management.
PCI scope-limitation by default.
Cardholder data never touches systems that don't need it. Tokenization-first thinking.
Ledger-safe defaults.
Idempotency keys, retry semantics, and immutable journals are our starting point.
BAA/NDA-ready onboarding.
Legal, compliance, and background-check processes move in parallel with engineering matching.
Embed senior engineers into your team — people who understand your stack, your regulators, and your sponsor bank.
