Card issuing APIs and operations platform for fintech

Software Development New York 51–200 employees Privately Held

Lithic operates a card issuing processor API that abstracts away legacy infrastructure complexity for fintech companies. The stack—Java, Python, Node.js, PostgreSQL, AWS—is standard backend fintech, but the hiring mix reveals the real work: 10 of 17 active roles are engineering, with senior engineers dominating. The project list (card and account lifecycle features, developer tooling, Rust platform work) and pain points (ledger reliability, reconciliation, resilience, scaling production) show a company building infrastructure reliability and operational tooling in parallel to product velocity.
