Senior Product Manager (Payments)

• At Medius, you’ll join a diverse, global community where curiosity is celebrated, ideas matter, and innovation never stops
• Medius Payments is a fast-scaling product within Medius’s Spend Management platform, with an ambitious roadmap spanning the UK, Benelux, Nordics, France, and North America
• We serve customers from upper mid-market to enterprise, and our payments capability — including B2B card programs — is a strategic growth driver for the business
• We’re looking for a Senior Product Manager to own a significant domain within Medius Payments, sitting at the intersection of B2B card products, payment rails, partner integrations, and spend management workflow automation
• This is a senior, highly executional role for someone who has shipped complex B2B payments products at scale and can operate across strategy, discovery, and delivery without losing altitude
• You’ll own the vision and roadmap for your domain, work hands-on with engineering and design, navigate payment partner relationships, and ensure our card and payment capabilities meet the commercial, and compliance demands of mid-market and enterprise Finance teams across multiple geographies
• You’ll be the payments product voice in cross-functional conversations and a go-to expert for cards (virtual, commercial, and buyer-initiated), payment rails, and B2B payables flows
• This is not a coordination role — you’ll spend most of your time doing the work
• Own the product roadmap and outcomes for your domain within Medius Payments, with particular focus on B2B card programs (virtual cards, commercial cards, buyer-initiated payments) and underlying payment rails
• Define and defend prioritization decisions with clear commercial and customer rationale, balancing near-term execution with longer-term strategic bets
• Monitor the B2B payments landscape — including emerging payment schemes, open banking developments, and regulatory shifts across US, UK and EU — and translate these into actionable roadmap inputs
• Write and refine detailed PRDs, user stories, and acceptance criteria; own specs from discovery through to release
• Partner closely with engineering and design to shape solutions, review flows, and ensure delivery quality — including rolling up your sleeves on 3rd-line support and bug triage
• Drive integration design with external payment partners, card scheme networks, and banking providers, ensuring technical and commercial alignment
• Translate product vision and complex regulatory requirements into clear, scalable product requirements without losing commercial pragmatism
• Serve as the senior payments’ product expert in commercial, sales, and customer conversations — articulating capability, limitations, and roadmap direction without over-committing
• Build and maintain strong working relationships with payment partners
• Collaborate with Medius Suite PMs to ensure Payments changes are coordinated across the broader AP and Spend management platform — even small changes can have large-scale downstream or upstream impact
• Support go-to-market teams with product expertise, enablement materials, and launch documentation
• Work with the legal and regulatory team to monitor global payment regulation changes and proactively adjust execution plans to maintain compliance readiness across all active geographies
• Apply sound risk and control thinking to product design, particularly for card issuance, payment initiation, and supplier-facing flows
• This role is a Pod Lead in Medius’s AI-native operating model. You are the single accountable leader of one of the Payments value stream pods — directing the work, leading engineers’ day to day, and owning the outcome. There is no engineering manager beneath you
• Drive agent leverage within the pod
• Use AI tooling to accelerate discovery
• Own pod velocity as a first-class accountability: spec build ship
