ERP Integration Product Manager

At Medius, we believe finance should empower strategy, not stress. Founded in Sweden in 2001, we’ve grown from a local startup into a global leader in cloud-based spend management. Thousands of organizations trust our AI-powered solutions to simplify processes, eliminate manual work, and give finance teams clarity, confidence, and control.

If you want to make a real impact, see your ideas come to life, and shape the future of finance, Medius is the place for you.

Job overview

Medius connects to our customers' ERPs so invoices get coded, approved and paid without anyone retyping anything. As ERP Integration Product Manager for either our SAP or our D365 F&O integration, you own it: what it does, what gets built next, and whether it holds up when a customer's finance team is closing the month.

You'll work in the Connect area and report to the Group Product Manager for Connect.

What you’ll do

• Own and prioritise the backlog for your ERP integration, balancing customer needs, technical debt and roadmap goals.
• Run discovery with customers, partners and internal teams. Use AI and agents where they help you get to the real problem faster (synthesising calls, mining support tickets, testing assumptions), and be clear about where you still need to talk to a human.
• Turn what you learn into specs that engineers and AI coding agents can build from: clear problem statements, epics, user stories and acceptance criteria.
• Define test cases and scenarios, and test the work properly before you accept it.
• Work daily with engineering in sprints. Answer questions, make trade-offs, accept finished work.
• Shape the Connect roadmap with ERP-specific insight: market trends, ERP release cycles and customer demand.
• Work with Product Managers in other areas on cross-product discovery. Share customer insight, agree the problem and scope, and make sure ERP integration needs show up early rather than late.
• Be the ERP subject-matter expert for Customer Success, Support, Sales and Implementation.
• Keep an eye on the SAP or Microsoft ecosystem (release waves, APIs, deprecations) and work out what each change means for us.
• Share patterns with the other Connect Product Managers so the integration framework stays consistent.

What we’re looking for

• Real product management experience (Product Manager, Product Owner, or a functional or technical consultant who has moved into owning product decisions) in B2B SaaS or an ERP environment.
• Working knowledge of either SAP (S/4HANA, ECC, MM, FI, ABAP) or D365 F&O (accounts payable, general ledger, taxes, TMS and landed cost).
• A good grasp of finance and AP processes: invoice-to-pay, master data, posting and payment flows.
• An understanding of integration concepts: APIs, event-driven patterns, authentication and error handling.
• Hands-on, practical use of AI tools in your own product work, ideally agents in discovery or analysis. We care more about what you’ve actually tried and learned than which tools you’ve used.
• Some experience with spec-driven development, or a real appetite to learn it. That means writing specs precise enough that the people (and agents) building from them don’t have to guess.
• Clear written and spoken English, for technical and business audiences alike.
• You can pick up a problem and run with it without being chased.

Nice to have

• Hands-on ERP implementation or integration project experience.
• Agile practice and backlog tools (Jira, Azure DevOps).
• Familiarity with other ERPs in the Connect portfolio (D365 Business Central, NetSuite).

What We Offer

• Well-being perks: MyBenefit Program, Private Healthcare, Life Insurance, B-Day Off, Training Budget
• Fun & Connection: Summer & Winter Parties, Team Events
