• You have experience with technical proposals, tenders, and system specifications
• You communicate confidently in English
• You hold a degree in Engineering, Electrical, Energy, or a related field
• You’re proactive, self-driven, and comfortable in a fast-paced, international environment

• enjoys solving problems, not just selling products
• thrives at the intersection of technology and business
• wants to actively shape the energy transition - not just talk about it

Why Lyten:

• Work with next-generation battery technology
• Play a real role in scaling BESS across Europe
• Join a fast-growing, international team
• Competitive compensation (starting from 12,000 PLN/month + benefits)
