Senior Backend Engineer - Transaction
Ether.fi, New York +2
The role
We’re looking for a senior backend engineer to own core parts of our card program: transaction processing, authorization and decline handling, disputes, and the services around them. You’ll work on a small team where engineers own problems end to end, from understanding why a user’s card was declined to shipping the fix and measuring whether it worked. Anything a neobank would build is on our roadmap.
What you will do
- Own core backend services for our card program, including authorization, clearing, refunds, and dispute flows
- Reduce user friction from card declines: find root causes in transaction data, work with our issuing partners, and ship fixes
- Make product calls alongside design and ops: decide what to build, cut scope where it doesn’t serve users, and track outcomes after launch
