What you'll own

• Customer management & field engagement. Identify and build relationships with new customers. Attend meetings, site visits, technical presentations and solution discussions alongside senior team members. Support commissioning, start-up and handover for pilot and early customer installations.
• Technical sales support. Understand customer requirements and help shape technical solutions based on our technology that fit their needs while aligning with our commercial goals. Support pre- and post-sales activities as a conduit between the customer and MAGNOTHERM technical team.
• Proposals & documentation. Prepare technical proposals, drawings, calculations and supporting documentation for customer opportunities, working from standard configurations toward tailored solutions.
• CRM & market insight. Maintain opportunity and customer records in our CRM (HubSpot), tracking activities and deal progress. Monitor market trends, competitor activity and customer feedback to help inform GTM strategy and product development.
• Coordination & knowledge. Support project planning, equipment selection, delivery and implementation scheduling in coordination with our technical teams. Build product knowledge to support training for customers, partners and GTM colleagues. Travel occasionally within Europe to support customer visits, trade fairs and site assessments.

What you would ideally bring to the table

Must-have skills & experience

• A Bachelor's degree in engineering, a technical discipline, business, or a comparable field (or equivalent experience).
• Strong technical aptitude and the ability to translate customer requirements into practical solutions.
• Strong, confident communicator with both technical and non-technical audiences.
• Structured, self-driven, and dependable — comfortable owning tasks without heavy oversight.
• Comfortable with standard business tools and CRM systems (we use HubSpot).
• German language skills (C1+), English language skills (C1+). Please note that the language requirements for this role are non-negotiable.
• Willingness to travel within Europe as needed (please note you will be at our Darmstadt HQ the majority of the time, this is only occasionally).

• Exposure to industrial, cold chain, HVAC, refrigeration or related technical markets.
• Interest in or experience with channel/distributor relationships.
• Strong problem-solving and analytical skills.

What makes this role unusual

• You're not just supporting deals — you're helping define how an entire industry evaluates and adopts a cooling technology that doesn't exist anywhere else yet.
• Direct exposure to founders, engineering and GTM leadership from day one, with real room to help shape how technical sales works at MAGNOTHERM.
• Opportunities to expand your skillset, grow with the company, or develop into a more senior role.

What you will get from the job

• Flexible hours and 30 days of vacation.
• Compensation aligned with startup standards, with room to grow as the company scales.
• A team that's sharp, interdisciplinary, and doesn't take itself too seriously.
• The chance to pioneer technology that actually helps the planet.
• Ownership, responsibility, and a culture where learning from mistakes is expected.
• A front-row seat as a deep-tech company scales.
• Memes. Good ones. And lots of them.
