Kira builds banking infrastructure for global companies operating across borders.
We enable businesses to launch usd bank accounts, payments, and stablecoin rails for their customers — even if those customers live outside the u.s. Today companies like exchanges, fintechs, marketplaces, and payment platforms use kira to move money between fiat and crypto, across countries, and across banking systems.
We are not building a fintech app.
We are building the underlying financial operating system.
This role is for engineers who want to design systems that banks themselves rely on.
The role
we are hiring a senior banking infrastructure architect engineer to design and build the core financial infrastructure powering kira.
You will architect and implement the foundational systems that make kira a programmable bank:
the core banking ledger
a proprietary ai-driven transaction monitoring / kyt engine
this is not a feature team role.
You will define how money moves through the company.
You should be comfortable making irreversible decisions — data models, ledger invariants, reconciliation strategy, and regulatory‑grade auditability.
What you’ll build
1) core banking ledger
design and implement the system of record for money at kira.
You will own:
double‑entry ledger architecture
balance correctness guarantees
idempotent posting engine
multi‑currency accounting (fiat + stablecoin)
historical audit reconstruction
time‑travel queries for compliance investigations
high‑throughput posting engine (not batch accounting)
your job is to ensure balances are never wrong — even during outages, retries, and partial failures.
2) banking-as-a-service infrastructure
build the orchestration layer between kira and sponsor banks / payment rails.
You will design:
virtual account routing
payment ingestion and normalization
