About the Role

EFT Energy Solutions is a fast-growing European integrator and service partner specialising in commercial and industrial battery energy storage systems (BESS). As our Inside Sales & Customer Support specialist, you will be the day-to-day point of contact for our German-speaking customers and partners -- handling enquiries, preparing quotes, managing orders, and making sure every customer interaction is handled professionally and promptly. You will work closely with our field sales team to keep them focused on the road while you take care of everything behind the scenes. Over time, strong candidates will take on independent responsibility for smaller accounts, handling the full cycle from first contact to closed deal. The role is based remotely in Spain, with occasional travel to Germany for customer visits and industry events.

Key Responsibilities

1. Customer Support & Inside Sales

· Serve as the main contact for inbound enquiries from German-speaking installers, distributors, and partners

· Prepare and follow up on quotes, pricing requests, and product proposals

· Handle order processing and coordinate with logistics, finance, and technical teams

· Manage smaller accounts independently -- from first contact through to order confirmation and repeat business

2. Field Sales Support

· Back up the field sales team: prepare materials, handle follow-ups, and cover customer communication during travel

· Keep CRM data up to date: contacts, deal stages, account activity, and pipeline entries

· Support onboarding of new partners: documentation, account setup, and first-order coordination





· Help prepare sales presentations, product comparisons, and offer documents in German

3. Account Development

· Proactively follow up with existing customers to identify repeat order opportunities and new project needs

· Flag upsell and cross-sell opportunities to the field sales team

· Build strong working relationships with accounts through consistent, reliable communication

4. Internal Coordination

· Act as the bridge between German-speaking customers and internal teams

· Support translation and localisation of sales materials and communications into German

· Contribute to improving internal processes for customer communication and order handling

Requirements

· Fluent German at C2 / native level -- written and spoken; this is a hard requirement for this role

· Good English -- required for internal team communication

· Spanish language skills are an advantage

· 2-4 years experience in inside sales, sales support, customer service, or account management in a B2B environment

· Comfortable handling customer calls and written communication independently and professionally

· Organised approach to managing multiple open quotes, orders, and follow-ups simultaneously





· Experience with CRM tools

· Comfortable working remotely and collaborating with colleagues across Europe

· Willingness to travel occasionally -- customer visits in Germany and European trade events a few times per year

· Background in or enthusiasm for solar PV, battery storage, or energy technology is a plus

What We Offer

· A central role in a growing European energy storage business -- your work directly enables the sales team

· Remote work from Spain with adaptable working arrangements

· A small, international team with flat hierarchies and short decision-making paths

· Clear path to more responsibility: successful candidates will grow into independent account ownership

· Occasional travel to Germany and other European markets
