- Freshness 15 / 15 How recently it was posted. Older postings are likelier to be filled or abandoned.
- Remote clarity 15 / 15 Whether "remote" means anywhere, or is quietly restricted to one country.
- Role specificity 6 / 10 Whether the listing is tagged well enough to tell what the role actually is.
- Corroboration 5 / 10 Whether more than one source carries this listing.
- Pay transparency 0 / 25 A published salary range, worth more than any other single factor because it is what a candidate cannot find out without applying.

- Ensure secure handling of payment data and compliance (PCI DSS)
- Maintain and monitor existing PSP connections; resolve integration issues
- Set technical direction, review code, and mentor other engineers
- Build reporting and logging for payment operations and troubleshooting
- Support anti-fraud, AML, and KYC checks within payment flows
Requirements:
- 5+ years backend engineering experience (API and integration heavy)
- Strong Ruby / Ruby on Rails expertise; production Go experience strongly preferred
- Proven experience integrating PSPs or payment gateways
- Solid understanding of payment flows, webhooks, and transaction lifecycles
- Knowledge of PCI DSS and secure handling of financial data
- Experience with reconciliation, idempotency, and error-handling patterns
- Experience designing and scaling distributed backend systems
- Experience in fintech, payments, or forex/CFD brokerage preferred
- Strong attention to reliability, security, and detail
What We Offer:
- Fully remote role
- Schedule: Monday–Friday, 9:00 – 18:00
