Payments Systems Consultant / Architect

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.

About our client

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

Offer & Terms

OFFER & TERMS
- Two ways to join a stable, Fortune 500-backed international company — full-time employment (HPP) or a long-term B2B contract.
- Direct impact on the architecture and performance of systems clearing millions of card transactions a day, with a real migration to ship.
- HPP: 110,000–140,000 CZK gross/month + up to 10% annual bonus. B2B: up to 180,000 CZK/month (registered freelance/business licence required).
- 5 weeks of vacation + 5 additional paid days off (HPP)
- CZK 18,000/year allowance for vacation, sport or leisure (HPP)
- Meal vouchers fully covered; pension contribution (HPP)
- Flexible hours and hybrid mode; language courses; mental-health support and online medical service (HPP)
- Office refreshments and snacks (HPP)

100.000 - 110.000 Kč

One of the world's largest logistics networks — land, sea, air, 220+ countries. The IT backbone behind it: 5,600+ specialists globally. The Prague team is part of core engineering delivery, not a regional satellite. For this specific mobile area, there are two analysts based in Prague right now. You'd be the third. Mobile use cases on the platform are expanding. The engineering capacity is there. What's missing is clarity — what to build, why, and in what order. The previous person in this role moved into a broader function within the company. People here grow — they don't leave. This position is re-opening at a time when the mobile scope has grown, so it's not a straight replacement. The work has expanded beyond what two people can own alone.What Matters Most: Forget a long checklist. This role comes down to three things: * You understand delivery — you can tell a clean backlog from a mess. You know what "done" should feel like before the first ticket gets written. * You think in problems, not tickets — you don't take a brief at face value. You dig until you find the real ask, then shape the solution. * You push back with substance — stakeholders expect a real conversation, not a nod. The dev team expects clarity, not ambiguity. You're comfortable holding that line on both sides. English at a level where written communication does the heavy lifting — you're distributed across time zones, so a well-written update or requirement doc often replaces a call. Your async written English matters as much as your spoken English. High-level mobile knowledge matters — Android/iOS ecosystem, app lifecycle, enterprise distribution. You won't write code. But you need to know what the conversation is about. Nice to Have: * Experience in enterprise or regulated environments * Basic orientation in cloud platforms (Azure, AWS, GCP) from a business perspective * Experience with internal mobile app distribution * Agile certifications (Scrum, SAFe, or similar) These describe the platform context — not hard filters for selection.Your job is to close the gap between what the business wants and what gets built. That means going past what stakeholders say they need. Finding the actual problem. Pushing back on weak briefs. Coming back to the team with a backlog that makes sense and can be picked up without another round of back-and-forth. The team covers the full product lifecycle end-to-end — from build to run. Around 15 people: developers make up the majority, with testers, delivery roles, a dedicated architect, and support. The Prague hub is small — three people, including this role. The rest of the team is internationally distributed across multiple time zones. You'll report directly to the Head of Mobile Delivery. That setup matters: you won't be a local BA coordinating within arm's reach. You'll be the bridge between Prague and a globally distributed team — which means strong written communication and the ability to move things forward without waiting for someone to follow up on you. Stakeholders know their domain. Conversations are direct, not hand-holding. Your influence here comes from expertise, not mandate. You don't own the final call — that sits with the business owner. But you're the one who shapes the quality of the decision before it gets made. That's what this role is actually about. After 12 months: delivery in your area is faster and more predictable. Requirements stop being a guessing game. Cross-timezone handoffs are clean — not a bottleneck. Stakeholders come to you early — not after things have already gone wrong. Key Responsibilities: * Go to stakeholders, understand the real problem behind each request, push back on weak briefs, and find the better solution — not just the easier one * Translate business needs into user stories, acceptance criteria, and backlog items the team can pick up and run with — no open questions left hanging * Run agile ceremonies: refinement, sprint planning, retrospectives — the team understands not just what they're building, but why * Keep business, development, and delivery connected across a globally distributed team — everything in English What This Role Is NOT: * Not a developer role — you won't write code * Not a passive role — you're not waiting for tasks, you're creating clarity * Not a Product Owner position — you'll shape and influence backlog decisions, not own them * Not a support or shift-based role Operating Model: Prague office, 2 days a week. Agile delivery. English is the working language — all communication, written and spoken, no exceptions. No shifts, no on-call. The team is internationally distributed; the bulk of the work happens through structured time-zone overlap, not pure async — but your written communication needs to carry weight when overlap ends. Tech context: Android/iOS (enterprise distribution), Node.js and Python backend, Jira, Confluence. Multiple product lines in scope.Interested?
