Job Description:

MRJ Recruitment is partnering with a global leader embarking on a large-scale payments transformation, reimagining their payments platform from the ground up.

We’re looking for a hands-on Technical Solutions Architect with a strong engineering background and deep payments expertise. You’ll define the architecture for a new, scalable payments ecosystem driving decisions that shape authorisation, capture, settlement, and reconciliation across multiple services and integrations.

What you’ll do:

  • Own and define the end-to-end target architecture across services, APIs, and operational components.
  • Lead early discovery, evaluating options, assessing risks, and shaping decisions at pace.
  • Design resilient, secure systems for payment flows covering banking, card schemes, and service provider integrations.
  • Set standards for engineering quality: API design, observability, reliability, and deployment.
  • Collaborate closely with engineering and product teams to turn complex requirements into elegant, scalable solutions.

What you’ll bring:

  • Engineering-first approach, you started in software engineering and evolved into architecture.
  • Deep payments knowledge, hands-on experience across authorisation, capture, and settlement.
  • Integration expertise with PSPs, acquirers, or networks (e.g. Worldpay, Adyen, Stripe, Square, Vocalink).
  • Strong banking and card scheme understanding, both technically and operationally.
  • Modern tech toolkit: Kotlin, Rust, React/Next.js, Android (or equivalent).
  • Comfortable shaping architecture in greenfield programmes with high ambiguity and big impact.
  • Clear communicator, able to influence technical direction across engineering and leadership teams.
