Elektroingenieur (m/w/d)

Job Description

Industrial heat accounts for nearly a quarter of global energy demand, and most of it still relies on fossil fuels. At ENERGYNEST, we're changing that.

We help industrial companies replace gas with clean, cost-competitive heat through integrated power-to-heat and thermal storage solutions. By combining engineering, energy expertise, and innovative business models, we're making industrial decarbonization commercially viable today.

Founded in 2011, ENERGYNEST is an international team of engineers, project developers, commercial experts, and problem-solvers united by one ambition: accelerating the transition to a fossil-free industry. If you enjoy tackling complex challenges, taking ownership, and building something that matters, you'll fit right in.

Why you should join our team

• Work on a relevant challenge: decarbonizing industrial heat with a proven technology in operation
• Join an international, growing company with a strong technical and commercial foundation
• Flexible working model, including working from home
• Flat hierarchies and close collaboration across teams and locations
• Modern office in central Hamburg (Gänsemarkt)
• Mobility & employee perks: fully covered Deutschlandticket, access to Corporate Benefits, and JobRad leasing options
• Modern IT equipment and setup for office and remote work

What you will do

The hired engineer will own the electrical scope of our industrial energy projects from feasibility through proposal and design, with a heavy focus on driving cost-efficient technical decisions.

• Electrical Architecture & Design: Define optimal electrical configurations (MV-LV), select and size key equipment (transformers, MV switchgear, cabling), and develop basic and detailed engineering documentation, including Single Line Diagrams (SLDs).
• Grid Integration & Client Interface: Assess client network feasibility, interpret grid data, and design the point of connection for integrating projects into existing industrial MV networks or future renewable (PV/wind) assets.
• Power System Studies: Conduct critical engineering evaluations, including load flow analysis, short-circuit calculations, and equipment sizing.
• Techno-Economic Optimization: Apply strong commercial judgment to evaluate design alternatives (e.g., assessing one vs. two transformers, or LV vs. MV connections) to optimize project CAPEX and competitiveness.
• Proposal & Supplier Support: Provide technical evaluations for ongoing project proposals, review supplier solutions, and verify that third-party equipment meets project requirements.

Your skills and experiences

We are looking for a fully autonomous, senior-level technical professional with a proven track record in medium-voltage grid connections and a strong understanding of the financial impact of engineering decisions.

• Experience: Approximately 6-10 years of experience with a solid background working in electrical EPC contracting, substation engineering, utilities/grid companies, or renewable energy integration (PV, wind, BESS).
• Technical Domain Expertise: Deep knowledge of medium-voltage systems (typically 10-30 kV), power transformers, MV switchgear, and electrical protection systems.
• Software Proficiency: Essential command of AutoCAD or EPLAN for design, combined with strong, recommended capability in power systems analysis software such as DIgSILENT PowerFactory or ETAP.
• Languages: Business fluent in German & English.
