Companies like Mercury, Flex, and Novo rely on Lithic's developer-friendly APIs, direct network connections, and flawless reconciliation to launch and scale card programs in weeks, not years.

We're proud to be backed by world-class investors who share that vision, including Bessemer Venture Partners, Index Ventures, Spark Capital, Stripes, and Mastercard, along with many others.

We're a team of 170+ across 26 states and 7 countries, headquartered in New York City.

Lithic's Treasury Operations team owns the movement of money across our card issuing infrastructure — network settlement, sponsor bank transfers, and the reconciliation that keeps it all provable. This is a hands-on, high-ownership role for someone who wants to learn the inner workings of payments and fintech infrastructure, not just observe them from a reporting layer.

You'll be running a critical, time-sensitive engine every day — and at the same time, working alongside the Head of Treasury Operations to improve how that engine works as the function scales. You’ll also work cross-functionally across a wide range of teams (Finance, Treasury Engineering, Risk, Analytics, Processing, Customer Success, Bank Operations) — this role sits at the center of a lot of different workflows, not off in a silo.

What you'll do

Execution (50%)

Own day-to-day execution of network settlement transfers (Mastercard, Visa) and related treasury transfers across sponsor banks
Operate in a time-sensitive environment where errors or delays have immediate downstream consequences
Support reconciliation and ensure transfers tie out against expected activity
Be a reliable, detail-oriented operator of an existing process — accuracy and consistency matter as much as speed

Process Optimization (20%)

Take existing workflows and make them better: fewer manual steps, stronger controls, cleaner audit trails
Identify friction or risk in current processes and propose (and build) improvements
Balance improvement work against the need for strong financial controls — nothing gets streamlined at the expense of auditability

Project Support (30%)

Support the Head of Treasury Operations on larger initiatives as the function scales
Contribute analysis, documentation, and execution support to new treasury infrastructure, reporting, or process builds

Ongoing

Run ad hoc data analysis (SQL, Excel) to answer operational and financial questions on the fly
Support downstream audit and reporting needs tied to settlement and reconciliation activity
Be available outside normal business hours in rare emergency situations (e.g., a failed settlement or bank-side issue)

What you'll learn

This role is a front-row seat to the nuts and bolts of card issuing and payments infrastructure — network settlement mechanics, sponsor bank relationships, and the guts of how money actually moves through a modern fintech stack. You'll come out of this role with a depth of operational fintech knowledge that's hard to get anywhere else.

What you'll bring

2–4 years of relevant experience in treasury operations, funds transfer/money movement operations, cash management, or a closely adjacent operational finance role
Experience with reconciliation and financial controls — you understand why the numbers need to tie out, not just how to make them tie out
Strong Excel and Google Sheets skills, including comfort with (or willingness to learn) Google Apps Script for automating recurring workflows
SQL proficiency for querying and validating data (we use Snowflake and Metabase); Python or other scripting is a plus, not a requirement
