Payment Integration Engineer

CXM Direct LLC · Cyprus (Remote) · Full-time · Posted 2026-09-23

About the Role

  • We are an international broker. Our clients fund and withdraw through approximately 60 payment methods across Asia, Africa, LATAM, and the Middle East.
  • Payments Product is now a standalone function, and we are building the team around it. This is an early core hire.
  • We are looking for a Payment Integration Manager who will own payment integrations end to end—from the initial technical call with a provider through to stable production.
  • You will also be the first line of response for every payment incident and the person responsible for deciding whether a new integration is ready to go live.
  • This is a technical operations role rather than a coordination role.

Key Responsibilities

Available integration types

  • Produce a 90-day breakdown of deposit attempts, categorised by outcome:
  • Abandoned during redirect
  • Completed but never confirmed back to the platform

Essential Qualifications & Experience

  • 4+ years of experience in payments, PSP integrations, or fintech platforms, with hands-on ownership of integrations rather than coordination alone.
  • Working knowledge of APIs, webhooks, asynchronous payment statuses, callback mechanics, confirmation models, redirect flows, and common failure modes.
  • Ability to review provider API specifications and identify missing information.
  • Experience using Postman or equivalent tools for API testing.
  • Experience performing structured checkout testing across mobile and desktop.
  • Proven ability to investigate live payment incidents using logs and API responses.
  • Ability to distinguish provider-side issues from platform-side problems.
  • Experience translating incomplete or ambiguous technical documentation into clear specifications for engineering.
  • Strong communication skills and composure during incidents.
  • Basic knowledge of using AI tools in daily work.
  • Working proficiency in both English and Russian, as both languages are used daily.
  • What Success Looks Like in the First Year

First Few Months — Operational Ownership

Take ownership of first-line payment incidents, build the payment method and provider catalogue using documentation and direct investigation, and produce the 90-day deposit attempt analysis.

By Mid-Year — Integration Acceptance Standards

Establish the integration acceptance framework and apply it to a live provider onboarding process, from initial engagement through production launch.

Second Half — Established Processes & Decision-MakingAs the team expands, a Systems Analyst will assume responsibility for formal verification, while the integration acceptance gate remains under your ownership.

Maintain an accurate and up-to-date provider catalogue, ensure the integration acceptance gate is fully operational, and take ownership of incident-related decisions.

Our recruitment process consists of four stages

  • HR Interview: Background, motivation, and overall role alignment.
  • Technical Interview: Payment integration knowledge, technical tools, hands-on experience, and incident diagnosis.
  • Product & Problem-Solving Interview: Integration decisions, prioritisation, and practical problem-solving.
  • Final Interview: Discussion with senior stakeholder.

Benefits

Fixed monthly compensation of \[depending on experience\]

  • Fully remote work within GMT to GMT+4, with no relocation required
  • End-to-end ownership of a provider from first call to production, and the go or no-go decision on every integration
  • Scope that grows with the business: cards, alternative payment methods, a card programme and new entities
  • Corporate AI tooling as part of the working process
