Let me tell you about the role
We are looking for a Senior Solution Architect with a strong focus on Payments Architecture to help design and deliver secure, scalable, and cost-effective technology solutions across our fuel, EV charging, and convenience retail business.
You’ll focus on detailed solution design and technical architecture within the payments domain, supporting both consumer-facing and in-store ecosystems. This includes POS systems, payment gateways, and integrations with acquirers, issuers, and third-party providers. You will design end-to-end payment flows (authorization, clearing, settlement) and ensure alignment with industry standards and security requirements.
This role is ideal for an experienced Architect who brings strong hands-on expertise, thrives in delivery-focused environments, and is ready to take ownership of solutions for focused projects or components within larger products/programmes. You will work closely with technical leads and delivery teams to translate complex payment requirements into robust digital solutions.
Key Responsibilities
Solution Design & Delivery
Design detailed, modular solution architectures with a strong emphasis on payment systems and integrations.
Lead the solution design for small-to-medium payment initiatives or contribute to larger architecture workstreams.
Collaborate with engineering teams to ensure high-quality implementation aligned with architecture principles and payment domain requirements.
Deliver Solution Architecture artefacts including sequence diagrams, payment flows, interface contracts, deployment models, and integration designs.
Technology & Standards
Apply MACH principles (Microservices, API-first, Cloud-native, Headless) and cloud-native design approaches, ideally with AWS services.
Ensure payment solutions align with industry standards such as PCI-DSS, EMV, ISO 8583, and tokenization practices.
Build foundational elements like security, observability, resiliency, and integration into all solutions.
Work within defined architecture standards, helping evolve reusable patterns and frameworks within the payments domain.
Collaboration & Delivery Enablement
Partner with business and technology teams to understand payment requirements and define pragmatic solutions.
Support agile delivery teams by providing ongoing architectural guidance during implementation.
Translate architectural decisions into actionable technical designs and development tasks.
Compliance & Risk Management
Embed security and compliance standards (e.g., PCI-DSS, encryption, data protection) into all solution builds.
Identify risks in payment processing and integrations early, proposing mitigation strategies aligned with governance frameworks.
Qualifications
Technical & Professional Skills
Bachelor’s degree in Computer Science, Engineering or equivalent experience.
At least 3–5 years in hands-on solution architecture or technical leadership roles.
Strong experience crafting and delivering payment architectures in retail or digital ecosystems.
Deep understanding of digital payments and retail payment systems, including authorization, clearing, and settlement flows.
Experience integrating with POS systems, payment gateways, acquirers, issuers, and third-party providers.
Familiarity with payment standards and protocols such as PCI-DSS, EMV, ISO 8583, and tokenization.
Exposure to modern payment trends including contactless payments, digital wallets, real-time payments, and API-driven ecosystems.
Experience designing solutions using cloud-native architectures, ideally on AWS.
Proficient in integration design patterns, API architecture (REST, event-driven), and microservices.
Good understanding of architecture domains (application, data, infrastructure, integration, and security).
Knowledge of DevOps practices, CI/CD pipelines, and agile delivery models.
Strong problem-solving and analytical skills, with the ability to evaluate…
