BESS Hardware Engineer
Back to all

We are a European energy technology company focused on advancing energy storage through innovative software and system design. Our mission is to develop safer, smarter and more sustainable alternatives for modern energy infrastructure. We are focused on transforming energy storage through advanced software, AI, and innovative battery technologies. Our solutions aim to deliver safer, more sustainable, and cost-effective alternatives to traditional systems.

We are looking for a hands-on BESS Engineer to help design and build Battery Energy Storage System (BESS) solutions as the company scales across Europe.

This role is ideal for an engineer who enjoys turning concepts into working systems — designing, prototyping, testing, and improving products in a fast-moving environment. You will play a key role in developing early-stage solutions and supporting their evolution into commercial products, ensuring reliability, safety, and compliance with European grid requirements.

What You’ll Do

  • Contribute to building and developing a high-performing engineering and R&D function

  • Design, develop, and integrate BESS system architectures, including batteries, inverters, EMS integration, and grid connection

  • Build and test prototypes and pilot systems

  • Support the transition from prototype to commercial product

  • Collaborate closely with hardware, software, and integration teams

  • Work on system protection, power quality, and control strategies

  • Perform system testing, troubleshooting, and performance optimization

  • Ensure compliance with EU grid codes, safety standards, and international requirements

  • Support technical documentation, certification, and regulatory processes

What We’re Looking For

  • Master’s degree (or equivalent) in Electrical Engineering, Energy Systems, Power Electronics, or a related field

  • Several years of experience in energy storage, power systems, renewables, or related technologies

  • Strong hands-on experience with BESS components and system integration

  • Experience with grid-connected systems, inverters, and battery technologies

  • Ability to design, build, test, and iterate on real hardware systems

  • Practical, problem-solving mindset suited to a startup environment

  • Experience with European or international energy projects is a plus

  • Strong communication and presentation skills

  • Fluent English and Finnish are required

Why Join Us

  • Opportunity to build energy storage solutions from the ground up

  • Hands-on engineering role with direct technical impact

  • Work in a fast-growing energy technology environment

  • Exposure to European markets with global technical standards
