We are looking for a Payment Integration Specialist to join Straal, who will bridge the gap between technology, product, and banking partners to make payments effortless.
We are not looking for a pure software engineer or a traditional project manager. We need someone with an analytical mindset (a background in QA/testing or technical support is ideal) who is comfortable navigating test flows with VPNs, digging into API docs, and jumping on calls with external partners or internal product teams. Your mission is to ensure our bank integrations (Open Banking, SEPA, and local payment methods) are smooth, UX-validated, and optimized for high checkout conversion.
Key responsibilities:
-
Map end-to-end integration paths, research technical requirements, and oversee the full lifecycle of new and existing bank integrations.
-
Test payment flows from the end-user perspective by managing test environments, configuring accounts, using VPNs, and validating UI filters.
-
Monitor integration performance, optimize bank selection layouts, and eliminate checkout friction points based on data insights.
-
Benchmark integration flows and performance against competitors and industry standards.
-
Drive technical issues and improvements end-to-end – from identifying root causes and gathering diagnostic data to coordinating with Dev, Product, Ops, and external providers.
-
Establish clear, repeatable onboarding and testing processes for upcoming bank integrations to help scale payment infrastructure.
-
Maintain proactive day-to-day communication with bank representatives, external providers, and internal teams.
-
Collaborate with data analysts and business stakeholders to evaluate performance metrics and prioritize upcoming integrations.
Minimum qualifications:
-
Experience in fintech, payments or e-commerce (particularly with Open Banking, SEPA, or payment gateways)
-
Strong technical understanding of web applications and browser architecture, with hands-on proficiency in Chrome DevTools.
-
Hands-on technical testing, troubleshooting network/browser issues, and capturing reproducible diagnostic data.
-
Ability to read and interpret technical API documentation and map complex integration dependencies.
-
High degree of ownership and curiosity – independently researching flows and documentation without relying on predefined templates.
-
Strong, proactive communication skills with a natural drive to connect with people and partner effectively with both engineering and business teams.
-
Proven track record of driving cross-functional initiatives to completion, collaborating closely with Tech, Product, and Analytics to validate hypotheses and measure conversion impact.
-
Fluent in English and Polish (written and spoken)
-
Ability to use AI tools effectively and responsibly in day-to-day workflows.
-
Availability to work in a hybrid setup (2–3 days per week from our Warsaw office).
Nice to have:
-
Practical experience testing APIs directly using Postman.
-
Strong eye for UX/UI design patterns and best practices in checkout flows.
