What impact you will have

The Product Line Owner is the end-to-end business leader for a product line of high-density cooling racks for AI and high-density compute. Acting as a “mini-GM,” the PLO owns market insight, product strategy, roadmap, and financial performance (P&L) from concept to end-of-life. The role combines deep technical understanding of liquid cooling and high-density AI infrastructure with strong business, negotiation, and stakeholder-management skills, ensuring the product line delivers sustainable revenue, margin, and customer value in a global, multicultural environment.

What you’ll do

1. Market and Customer Insight

• Build a deep understanding of the global market for advanced cooling AI infrastructure (hyperscalers, colos, micro-DCs, OEMs, integrators, telcos, enterprises).

• Conduct regular interviews with strategic customers, partners, and channels to understand AI density roadmaps, cooling strategies, constraints, and buying criteria.

• Analyse competitors (tanks, racks, CDUs, integrated micro-DCs) and adjacent technologies, identifying differentiation and white spaces for the product line.

2. Product Strategy, Roadmap, and Portfolio Management

• Define and maintain the product line vision and multi-year roadmap for high-density racks, and associated options (CDUs, manifolds, power integration, enclosures, services).

• Decide on new products, variants, and cost-down initiatives, balancing performance, density, cost, sustainability, and time-to-market.

• Align the product line roadmap with company strategy, sales priorities, strategic partnerships and industrial capabilities, in close collaboration with CPO and Engineering.

3. Business Case and P&L Ownership

• Own the P&L of the product line: build and update business cases, set volume and margin ambitions, and track performance versus plan.

• Define pricing structures (per rack, options, services) and discount frameworks with Finance and Sales, ensuring margin discipline in a high-CAPEX B2B context.

• Monitor revenue, gross margin, mix, and pipeline; propose and drive corrective actions (portfolio, pricing, cost, go-to-market) when targets are at risk.

4. Cross-Functional Leadership and Execution

• Lead cross-functional product line forums, bringing together Sales, Engineering, Supply Chain, Manufacturing, Quality, Sustainability, Compliance/Certification, Maintenance, and Support.

• Negotiate priorities and trade-offs (features, cost, lead time, density targets) with these teams, ensuring clarity of requirements and realistic commitments.

• Act as the single accountable owner for key product decisions and as the main escalation point for issues impacting the product line.

5. Product Definition and Lifecycle Management

• Translate market and customer insights into clear product requirements: thermal and power envelopes (e.g. 300–1000+ kW/rack), AI server types and form factor, fluid types, materials, serviceability, safety, certification, and integration constraints.

• Own the full lifecycle: introduction, growth, maturity, and end-of-life, including SKU/option strategy, complexity control, and migration paths to new generations.

• Ensure product documentation (spec sheets, integration guides, TCO/value tools) accurately reflects capabilities and constraints.

6. Sales and Go-to-Market Support

• Support Sales and Technical Sales Specialists on deals: positioning vs competition, solution configuration, trade-off discussions (density vs redundancy, CAPEX vs OPEX, cooling architecture choices).

• Contribute to launches, major bids, and strategic partnerships by preparing pr
