(Senior) Strategic Partner Manager (f/m/d)

At Moss, we give finance professionals the power to automate their day-to-day and make forward-thinking decisions.

Our culture is what makes that possible: we play to win, we obsess over quality, and we win as One Moss, and it works. Moss closed a €35 million Series C in August 2026, crossing a €1 billion valuation, and became one of Europe's fintech unicorns. Join us for what's next.

Moss is building its strategic partnerships function from scratch, and this is one of the first two hires shaping it. You'll take target platforms from zero relationship to live, revenue-generating integration, owning the sourcing, business case, and delivery for each one.

This is a build phase: you'll define your own playbook rather than follow one. You'll report to the Senior Director Partnerships and work closely with Product and Engineering on integration scope, and with the Channel team where partnerships overlap with existing ERP integrators.

Your responsibilities

• Source and build strategic partnerships from scratch, identifying platforms that fit Moss's customer base and growth priorities

• Navigate complex partner organisations to reach the right decision makers, from founders and C-level contacts at smaller platforms to Heads of Partnerships at larger ones

• Build the commercial and technical case for each partnership and secure buy-in from both Moss leadership and the partner's stakeholders

• Own each partnership end-to-end, from an initial referral or lightweight integration through to a live, revenue-generating relationship

• Partner with Product and Engineering to scope integration requirements and manage delivery against Moss's API and roadmap

• Collaborate with the Channel team where accounting-platform integrators already exist, to avoid overlap and align on commercialisation

• Define and adjust your own playbook, prioritising partners by revenue potential and strategic fit as the market picture sharpens

About you

• 5+ years in business development or partnerships within B2B SaaS, fintech, cloud, or payments

• At least 2 years specifically in strategic partnerships or integration-led partner roles, having built relationships from scratch rather than managed an existing book

• Working knowledge of APIs and how software platforms integrate with external partner systems

In addition, here are the skills and attributes we are looking for:

• Thrives with full ownership of a plan and pipeline, without needing day-to-day direction

• Brings structure to ambiguous, still-being-built processes and partnerships

• Communicates progress, blockers, and trade-offs clearly across product, engineering, and leadership

• Balances ambition with realism, adjusting timelines to partner readiness and internal constraints without losing momentum
