Own the acquiring-side authorization platform that clears card transactions in milliseconds. First you carry it through a host migration (BASE24 → PowerZac); then you keep developing, certifying and running it. The core of the job is analysis, solution design and product ownership of the platform.
Prague, hybrid — two days in the office. Open as full-time employment (HPP, 110,000–140,000 CZK gross/month + bonus and benefits) or as a long-term B2B contract (up to 180,000 CZK/month).
Czech or Slovak for the local team; English at B2–C1.
A leading international technology company specializing in the development and operation of payment systems — part of a Fortune 500 group, with technology used daily by millions of customers and businesses across continents. It keeps investing in innovation, including blockchain and digital-currency technologies, while its focus stays on secure, reliable real-time transaction processing.
The Prague team runs the core systems behind card payment authorization — and it's a Czech/Slovak-speaking team, not a place where you work purely in English across time zones. This role sits in the Authorization Centre and owns the product side of the authorization system, with the Acquiring part at its core.
Job description
WHY THIS ROLE EXISTS NOW
The team is mid-way through a strategic, multi-year migration: away from the current authorization host BASE24 (ACI) onto a new platform, PowerZac. The core system is delivered by a group subsidiary; the Prague team owns configuration, operations and the development around it — including the PERL scripts that translate messages into the various protocols.
The work runs from GAP analysis and implementation to connecting existing customers and surrounding systems onto the new solution.
Be clear-eyed about what this is. A host migration on a live authorization system is rare, and payment-authorization roles at this depth (DORA, PSD3 and Open Finance keep pushing demand) open maybe once every couple of years in CZ/SK. But it isn't only the migration — once the new host is in, you own its ongoing development, scheme certifications, improvements and day-to-day run. Migration is phase one of a long-term platform role.
ROLE / MISSION
You'll learn how the authorization system works end-to-end and own the design of solutions on the Acquiring side. You sit between business and the development team: you turn requirements into designs, estimate the effort to deliver them, and act as the single point of contact across teams — locally and globally. You'll report to the Core Processing Senior Director. It's an analytical, product-minded role with an IT background. It rewards curiosity, the willingness to dig into how things actually work, and the confidence to bring a bit of healthy disruption into an established team and sell your ideas. On a full-time basis it's a long-term seat: beyond the migration you keep developing, maintaining and improving the acquiring authorization platform. After the first months you're the person who understands the Acquiring authorization flows end-to-end, scopes and estimates new requirements with the team, and carries card-scheme certifications through without hand-holding.
KEY RESPONSIBILITIES
- Analyse business requirements with the Authorization Centre development team and others (e.g. the eCom team), design solutions and estimate the effort to deliver them
- Work into the relevant specifications, mainly from card associations (Mastercard, Visa, AMEX and others)
- Collaborate with the IT team and developers on new solutions — including out-of-the-box ones
- Examine and evaluate current systems; analyse and document interfaces between PowerZac and various customer and internal systems
- Run the certification process with card associations and support testing
- Provide operational support to customers, mainly at the level of association-rules design
- Stay current with solutions, products and technologies and share what you learn with the team
- Act as the single point of contact for various teams locally and globally
- Report progress honestly using the right tools (e.g. JIRA)
WHAT THIS ROLE IS NOT
- Not a pure development role — you'll read and understand PERL and write SQL, but the centre of the job is analysis, design and product ownership
- Not a BAU / support seat — this is change agenda, a real migration to ship, not ticket triage on a stable system
- Not a wait-for-the-assignment role — you bring ideas, prioritise, and stand behind your designs
- Not a lone-hero role — as the client puts it plainly: we're not looking for a hero, but a team player
OPERATING MODEL
Prague office, hybrid — two days a week in the office, the rest from home. You'll work in a Waterfall environment while several surrounding teams run Agile — being comfortable moving between both is part of the job. Daily cooperation with colleagues across global teams.
Requirements
WHAT MATTERS MOST
This role comes down to a few things:
- Payments depth: 5+ years as a Solution Consultant or within the payment-card industry; you know the banking / card sector, online payments, authorization, cryptography and e-commerce.
- Authorization hands-on: ISO 8583 message flows, an authorization switch/host (BASE24, PowerZac or similar) and dual-message processing.
- Design + value mindset: you define and explain algorithms, scope and estimate effort with the team, communicate openly with stakeholders, and don't over-engineer where it isn't needed.
Czech or Slovak for daily work within the local team; English at B2–C1.
NICE TO HAVE
(This is context, not a hard filter.)
- SQL and the ability to read and understand PERL scripts (a big plus)
- Scheme certification with Visa / Mastercard / AMEX (acquirer certification, test cycles)
- EMV, contactless and eCom (3-D Secure); familiarity with STIP (stand-in processing)
- PCI-DSS; hands-on software development and documentation background

- Two ways to join a stable, Fortune 500-backed international company — full-time employment (HPP) or a long-term B2B contract.
