Senior Manager (m/f/d) - Battery Value Chain at cylib GmbH

Your mission

This role sits at the intersection of sourcing and sales with a strong initial focus on the sourcing side. You will take end-to-end ownership of commercial opportunities from origination through negotiation and closing – working closely with interdisciplinary teams across the organization:

• You own the acquisition of battery feedstock – production scrap and end-of-life batteries – across selected channels and partners.
• You build and develop relationships with relevant partners across the battery, recycling, and waste ecosystem.
• You develop, structure, and negotiate sourcing and off-take agreements and drive them toward execution and closing.
• You drive commercial activities on the sales side for recycled products such as black mass, lithium carbonate, MHP, and related outputs.
• You monitor market developments, pricing trends, competitor activity, and partnership opportunities across the battery recycling ecosystem and translate them into actionable priorities.
• You evaluate the commercial attractiveness and strategic fit of sourcing and sales opportunities.
• You represent cylib as a trusted and capable partner in the circular battery materials market, including at fairs and conferences.

Your profile

• You bring several years of experience in business development, key account management, commercial partnerships, sourcing, or sales — in the battery, recycling, waste, metals, chemicals, or adjacent industrial sectors.
• You have a strong network in the battery industry, or recycling ecosystem, and know how to open doors, build trust, and develop long-term relationships in complex industrial markets.
• You have a good understanding of production scrap, end-of-life batteries, recycling value chains, or industrial waste streams.
• You are comfortable with the full commercial cycle: from spotting an opportunity to structuring a deal and getting it across the line.
• You are proficient with standard CRM systems and use them to track opportunities and keep your pipeline under control.
• You think and act like an owner by taking full end-to-end responsibility for your topics, setting your own priorities, and driving them to completion.
• You thrive in environments where structures are still being built and not everything is defined yet.
• You communicate clearly and confidently with internal and external stakeholders – in both German and English; further languages are a plus.
