Description
Purpose and mission The Product Manager (PM) is the strategic owner of one or multiple product areas within Piano’s portfolio. The PM translates business goals, market signals, and client insights into a compelling product vision and a prioritized program backlog. They work at the intersection of business strategy, client value, product marketing, product  design  and technology feasibility, ensuring that the right things get built, in the right order, for the right reasons. In the  SAFe  6 model, the PM  operates  at the Agile Release Train level, driving the Program Increment (PI) and empowering Product Owners to  execute with  confidence and autonomy. In an AI-accelerated product landscape, a PM at Piano is expected to actively  leverage  AI tools to sharpen market analysis, accelerate discovery, generate insights from data, and move faster at every stage of the product lifecycle. AI fluency is not optional — it is a force multiplier for every other responsibility in this role. The Billing PM owns Piano’s subscription billing infrastructure — the engine where subscriptions are created, invoiced, upgraded, renewed, and managed through Stripe Billing. Piano is  in the midst of  a large-scale platform transformation, replacing its internal billing engine with Stripe Billing across every subscription lifecycle event. This is not a surface-level product role. The PM  operates  deep inside billing logic: proration, upgrade and downgrade flows, dunning, invoicing, term management, and the integration boundary between Piano’s orchestration layer and Stripe’s billing primitives. The right PM has done this before —  they’ve  integrated Stripe Billing at  scale,  they understand  what breaks when billing logic gets complex, and they move fast without breaking revenue. Core responsibilities 1. Product Vision & Strategy • Co-develop and  maintain  a clear, compelling product vision for Piano’s billing domain in close partnership with Product Leadership, aligned with Piano’s broader subscription platform strategy. As the domain matures beyond  initial  transformation, this role is expected to grow into full strategic ownership of the billing product area. • Develop and own the billing roadmap over a 3– 12 month  horizon, balancing new capabilities, technical quality, and business priorities. • Conduct ongoing market and competitive analysis to  identify  opportunities, threats, and strategic positioning — particularly in the billing and monetization infrastructure space and at the boundary between Piano’s orchestration layer and Stripe Billing capabilities. • Track Stripe’s product roadmap and shipped capabilities to  identify  opportunities for Piano — know when Stripe solves a problem natively versus when Piano must build. • Define and communicate product positioning, target segments, and go-to-market priorities in collaboration with Marketing and Sales. 2. Backlog Ownership at Program Level • Own and  maintain  the billing Program Backlog (Features and Enablers) in collaboration with Product Leadership, Architects, and other PMs. • Prioritize features using value-based frameworks (WSJF, RICE, business impact, strategic fit) and maintain a rolling, well-groomed backlog  at all times . • Lead PI Planning preparation for billing: define PI Objectives, present the roadmap to the ART, and make prioritization decisions during planning. • Validate Feature acceptance criteria before development begins and approve Features upon delivery. 3. Stakeholder Alignment & Communication • Serve as the primary voice of the customer and the market within the ART for billing-related work, translating needs into Features the team can act on. • Collaborate closely with Sales, Pre-Sales, Customer Success, and Support to gather and synthesize client feedback on billing pain points, invoicing requirements, and subscription management needs. • Communicate  the roadmap and strategic priorities clearly and consistently to all relevant stakeholders, including executive leadership. • Represent the product in customer-facing contexts: executive meetings, key account workshops, conferences, and strategic partnership discussions. 4. Business & Performance Management • Define and  monitor  billing product KPIs and OKRs, with particular focus on billing accuracy, subscription lifecycle efficiency, revenue recognition, churn impact, and integration reliability. • Conduct product ROI analysis to justify investment decisions and support budget and resource discussions. • Manage the billing product lifecycle from  inception  to end-of-life, making proactive portfolio decisions in collaboration with Product Leadership — including managing the transition from transformation mode to steady-state innovation. 5. Go-to-Market & Launch • Lead the go-to-market strategy for new billing capabilities and major releases: beta programs, internal training, sales enablement, and  release  communication. • Collaborate with Marketing and PMM teams to produce effective product messaging, particularly around billing flexibility and subscription management as competitive differentiators. • Define and oversee the internal release process to ensure teams are prepared before customer-facing delivery. Collaboration model The PM does not work in isolation. Success in this role depends on effective collaboration: • With Product Leadership (VP, Product and at the ART and Portfolio levels):  The Billing PM works in close partnership with the VP who owns the strategic platform vision. Key decisions on scope, investment, and direction are made jointly. The PM brings domain  expertise , execution judgment, and market intelligence; Leadership provides strategic framing and cross-product alignment. • With Product Owners:  POs are assigned per initiative. PMs provide strategic context, prioritized Features, and clear acceptance criteria. POs translate these into actionable stories. The PM should be a trusted partner and enabler for POs, not a bottleneck. • With Architecture & Engineering:  PMs work with Architects to understand Stripe Billing’s technical constraints, integration patterns, and platform capabilities. Technical feasibility informs prioritization and roadmap planning. • With Product Design:  The PM sets the user experience ambition, defining the problems to solve, the user outcomes to target, and the quality bar expected. For billing, clarity and reliability of billing-related surfaces are core inputs to design decisions. • With Customer Success, Consulting & Support:  The PM ensures proactive knowledge transfer before releases, clear internal documentation, and well-defined escalation processes, so that client-facing teams can resolve billing issues and answer questions with confidence, without systematically falling back on Product. • With GTM teams:  PMs  are responsible for  enabling Sales, Pre-Sales, and Marketing to confidently present and  sell Piano’s billing capabilities at all times . What success looks like • The billing roadmap is clear, up-to-date, and well understood by all stakeholders — reflecting both the platform strategy and the realities of Stripe Billing integration. • PI Objectives are ambitious yet realistic and are consistently met or exceeded. • Product Owners feel empowered, well-informed, and able to  operate  autonomously within their initiatives. • Billing drives measurable business value: subscription lifecycle efficiency, billing accuracy, revenue impact, and client satisfaction with billing operations. • The team builds the right things,  validated  by client outcomes and revenue impact, not just delivery volume. • Stripe’s evolving capabilities are tracked and  leveraged  proactively — the PM knows when to build and when to wait. • Field teams (Pre-Sales, Sales, Client Success…) are informed ahead of releases, equipped with the right materials, and feel like active contributors to the billing roadmap, not just recipients of it. • Strategic changes and trade-offs are communicated proactively and with confidence. Key competences Hard skills • Deep domain  expertise  in subscription billing, invoicing, and recurring revenue infrastructure • Hands-on experience with Stripe Billing integration and configuration — this is a must-have • Understanding of billing logic complexity: proration, upgrades/downgrades, dunning, tax handling, multi-currency, revenue recognition • Market and competitive intelligence in the billing and monetization space • Product strategy and  roadmapping • Business case development and ROI analysis • Scrum,  SAFe , and agility at scale • Data-driven decision making • Working  proficiency  in English • Other European languages are a plus • AI-augmented product practices (discovery, analysis, synthesis, prototyping, internal tooling) Required experience • Demonstrated PM experience leading billing, subscription management, or recurring revenue infrastructure products • Track record  of working on Stripe Billing integration at scale — configuring, extending, and  operating  Stripe Billing within a product platform • Experience on fast-moving, large-scale billing infrastructure projects with global reach • Strong research capabilities and domain depth in billing, monetization, and subscription economics • Understanding of how billing decisions affect downstream metrics: retention, LTV, churn, and revenue recognition • Experience working in or alongside payment provider ecosystems Employment & benefits • B2B contract • Hybrid work model • Benefits: 20 days of paid leave, Lunch Card, Luxmed
