About H.E.A.T.

H.E.A.T. develops power plant control software with a focus on resilience, market integration, and bringing AI-based tooling to service. Our customers are EPC/Distributors/IPP combining gensets (diesel, gas, CHP) with renewables and industrial batteries.

The Role

As Senior Sales & Partnership Manager, you will own and grow relationships with our most important partners while actively identifying and developing new strategic partnerships. You will seek out companies where H.E.A.T. can become a long-term technology partner and take those relationships from initial contact through to established collaboration.

Rather than focusing on quick, transactional sales, you will build lasting partnerships and organizational alignment, helping partners integrate H.E.A.T.’s software into their core processes and project portfolios. The role combines proactive business development with patient, hands-on relationship management and requires the ability to navigate and collaborate with large industrial organisations.

What You’ll Do:

• Own and develop long-term relationships with our key partners. Build a strong understanding of each partner’s organisation and needs.
• Identify and develop new strategic partners, from initial targeting and outreach through to establishing long-term commercial relationships.
• Work with the founders to create account plans and agree on clear milestones.
• Build trusted relationships across management, commercial and technical teams. Support partners in incorporating H.E.A.T. into their sales, design and delivery processes.
• Coordinate closely with H.E.A.T.’s product and engineering teams to ensure partner needs are understood and addressed.
• Identify growth opportunities with partners such as training and longer-term commercial agreements.

What You Bring:

• 5+ years of experience in Sales, Key Account Management, Product Management or similar roles in the battery, power generation- or industrial technology sector.
• Track record of managing and developing highly technical partnerships that require thorough product and industry understanding.
• A relationship builder who listens carefully, understands how organisations function and can bring different stakeholders together.
• Ability to operate independently in an early-stage company. Comfortable travelling (primarily within Europe).

Nice to Have:

• Prior experience working with generator/CHP distributors or manufacturers, EPCs, system integrators or similar.
• Fluency in German.
