Senior Sales Executive — Energy Storage (BESS)

About the company:

KIEFER is building Greece's integrated AI ecosystem. From renewable energy infrastructure and AI systems to robotics and enterprise applications, we connect the technologies that power Europe's intelligent future. Founded in 2014, KIEFER has delivered 600MW+ of energy projects and is now developing sovereign AI infrastructure, enterprise AI products and physical AI systems for Greece and Southeast Europe.

KIEFER TEK is expanding its EPC capabilities in energy storage and is looking for a senior commercial leader to drive the growth of its BESS business

You will originate and close utility-scale BESS EPC contracts with developers, IPPs, funds and industrial off-takers, running deals end to end from first meeting to signature alongside Engineering, Procurement and PMO, and shaping the pricing and contracting approach for a newly prioritised portfolio. You will also lead the differentiation argument that increasingly decides these deals — how energy management, analytics and AI-assisted dispatch optimisation improve availability, revenue stacking and levelised cost of storage.

What you'll do

• Map the Greek and regional storage landscape and build a structured, prioritised pipeline
• Run opportunities end to end — qualification, technical scoping, proposal build-up, negotiation, and handover to PMO after signature
• Shape pricing architecture and contracting models (turnkey EPC, EPC wrap, Balance of Plant, EPC + long-term service agreements) with Engineering, Procurement and Finance
• Translate CAPEX, EPC scope, round-trip efficiency, degradation/augmentation and availability guarantees into commercial narratives that hold up to investor and lender scrutiny
• Lead the digital and AI value conversation — forecasting, dispatch optimisation, state-of-health analytics — and its effect on revenue stacking and levelised cost of storage
• Track tender schedules, capacity mechanisms, grid connection terms and competitor positioning
• Maintain CRM discipline and produce reliable weighted-pipeline forecasts
• Represent KIEFER TEK at industry conferences, tenders and investor events

What we're looking for

• 5–7+ years in Sales or Business Development within Energy, EPC or Renewables, with a track record of closing complex, long-cycle B2B contracts
• Direct exposure to utility-scale BESS strongly preferred; adjacent experience in Solar PV, Wind, substations or grid connection works valued
• Working command of BESS commercial fundamentals — revenue stacking, augmentation, EPC vs. BoP scope splits, availability guarantees, levelised cost of storage
• Genuine literacy in AI and digital optimisation of energy assets, and the ability to apply AI tools to your own commercial work
• Bachelor's degree in Engineering, Energy, Business Administration or related field (Master's a plus)
• Fluency in Greek and English
• Valid Category B driving licence and readiness to travel 30–40%, primarily in Greece with regular travel across SE Europe

What we offer

• Competitive compensation package, with full pay transparency throughout the recruitment process

• Performance-based bonus linked to commercial results

• Company car and fuel allowance

• Private medical insurance

• Professional development in BESS, energy markets and AI-enabled energy solutions

• Participation in key industry conferences and events

• High level of autonomy and direct access to senior management

• The opportunity to play a key role in developing KIEFER TEK’s Energy Storage business
