About the role

Key responsibilities & impact

You are responsible for the entire commercial process: from first outreach to contract signature.
You independently build a pipeline within the industrial SME sector and engage the right decision-makers.
You conduct discovery calls, attend on-site meetings and translate clients’ technical and economic concerns into concrete solutions.
With support from our technical team, you perform analyses of customer sites.
You negotiate, keep opportunities progressing through the sales process, and persist even when decisions take multiple iterations.
You actively contribute market feedback to product, positioning and messaging.
You expand and refine our existing sales playbook.

Requirements

What you’ll need

At least 3 years of experience in B2B sales, project sales or consulting-oriented sales.
Proven closing experience: you have driven deals from acquisition or early qualification through to signature yourself, ideally in six-figure project business.
Motivation to build your own pipeline, proactively approach new customers and follow through consistently.
Experience in energy, photovoltaics, battery storage, contracting, energy efficiency or technical capital goods.
Experience with industrial SMEs or complex, consultative investment projects.
Strong understanding of economic and technical topics and the ability to explain business cases clearly.
Professional demeanor when interacting with executive management, technical decision-makers, energy managers and procurement.
High level of autonomy, a fast learning curve and enthusiasm for driving significant impact in a young company.
Business-fluent German, as nearly all customer conversations take place in German.
Willingness to attend regular on-site meetings with customers across Germany.
A clear plus but not required: a technical, engineering or energy-economics background.

Benefits

Comp & perks

€60,000 to €130,000 total compensation, consisting of base salary and variable pay.
Good setup: attractive Berlin office, BahnCard 50, expense reimbursement and equipment of your choice.
Direct impact: with every system you sell you support the energy transition, reduce energy costs for industrial companies and contribute to measurable CO₂ savings.
Growth market — battery storage: build expertise in a market that is currently expanding and will grow in importance in the coming years.
Validated sales approach: you won’t start from zero. We actively sell ourselves, have satisfied customers and will provide you with market knowledge, arguments and references.
Work directly with the founding team: you’ll work closely with the founders, benefit from short decision-making paths and actively shape FION’s commercial development.
Steep learning curve: develop in sales, energy, product understanding, customer strategy and company building.
Significant room for growth: you can test new approaches, help build processes and potentially take on more responsibility in the sales team.
Product with growing demand: you’re not selling a nice-to-have — you’re selling a product with clear economic benefits in an increasingly relevant market.
We are an early-stage company. Not everything is perfect, and that’s precisely why you can make a big impact here. At the same time we’re not starting from zero: we actively sell, know our customers and understand what works. You will build on a real foundation.
