eero, an Amazon company, builds the Wi-Fi and networking systems that homes and businesses rely on every day.

You'll own the commercial relationship, from start to finish, with an assigned set of eero's Tier 1 EMS/ODM partners in the US and Asia. That means negotiating multi-year master agreements, leading RFQs for new programs, and managing contract manufacturing spend across your partner portfolio. You'll negotiate directly with those partners' executive teams, set the commercial terms for how eero builds its products with them, and hold them to their commitments on cost, quality, delivery, and flexibility You'll work with eero Hardware Engineering, Manufacturing, Quality, Planning, Operations, Finance, and Legal, and procurement teams. Together you'll shape eero's long-term manufacturing footprint. Key job responsibilities Commercial strategy and negotiation • For your assigned Tier 1 EMS/ODM partners, negotiate all commercial aspects of eero's relationship: Master Supply Agreements and Statements of Work, multi-year pricing, manufacturing value-add (MVA) and margin structures, NRE, tooling and IP ownership, payment terms, liability, warranty and epidemic failure, excess and obsolescence (E&O) liability, capacity commitments, and exit and transition terms. • Lead competitive RFQs for new programs and re-sourcing events in your portfolio. Own the full process: strategy, partner shortlist, should-cost targets, award recommendation, and signed contract. • Build and defend should-cost and total landed cost models (BOM, MVA, freight, duty and tariff, FX, inventory carrying cost) • Deliver year-over-year structural cost reductions, and own the contract manufacturing cost roadmap for your partner portfolio against annual operating plan targets.

Run executive business reviews, resolve escalations at the senior level, and act as eero's senior commercial voice with those partners. • Run partner governance and scorecards for your partners, using a common framework across eero's Tier 1 portfolio. Scorecards cover cost, quality, delivery, responsiveness, flexibility, and business continuity. Use commercial levers to drive performance. Risk, flexibility, and financial accountability • Structure agreements that protect eero from demand volatility: upside flexibility, downside liability caps, lead-time commitments, and buffer, VMI, or hub arrangements. • Own the commercial resolution of E&O, purchase price variance (PPV), NRE, and partner claims. • Contribute to tariff, trade compliance, and geopolitical risk, including country-of-origin strategy and supply continuity planning. Leadership and mechanisms • Set the operating mechanisms the OEM and supply chain team runs on: monthly business reviews, pricing cadence, quarterly business reviews, and contract lifecycle management. • Raise the commercial bar across eero Operations through coaching, templates, and negotiation playbooks. • Travel 1-2 weeks per quarter to partner sites in Asia and North America. A day in the life You might start your morning preparing a strategic proposal for a major partner negotiation, then shift to a cross-functional working session where you align product, engineering, and business teams on a new market opportunity. After lunch, you could be leading a business review with senior leadership, presenting data-driven insights and recommendations. Later, you'll connect with a mentee to discuss their career development before closing out with a call to an external partner's executive team to advance a deal that's been months in the making.
