Job Description

Position: Technical Project Engineer – Energy Solutions

Location: Wiesbaden

Key Responsibilities:

1. Technical Sales Support

Provide in-depth technical support to the sales team, including the design and customization of solutions tailored to customer needs across utility-scale and C&I (Commercial & Industrial) verticals.

2. Project Engineering Interface

Lead technical communication throughout the project lifecycle. Ensure mutual understanding of deliverables, responsibilities, and performance criteria between internal teams and external clients/partners.

3. System-Level Solution Design

Deliver integrated system configurations involving PCS (Power Conversion System), MV transformers, battery racks, and EMS/BMS platforms. Optimize proposals for functional performance and grid compliance.

4. Local Grid Regulation Expertise

Interpret and apply grid connection requirements across different European countries (e.g., CEI 0-21/0-16 in Italy, G99/G100 in the UK, NTS/REE in Spain). Maintain close tracking of regulatory updates and certification needs.

5. Technology Transfer & Learning

Rapidly master the architecture, key parameters, and integration logic of PCS, energy storage containers, and associated control systems. Deliver internal documentation and customer training when required.

6. Cross-Cultural Collaboration

Act as a bridge between the China R&D team and European project stakeholders, ensuring smooth technical handover and localized adaptation of product specs.

Credential Requirements:

• Educational Background

Bachelor’s degree or above in Electrical Engineering, Power Electronics, Energy Systems, Control Systems, or related fields.

• Industry Experience

Minimum 3 years of technical experience in one or more of the following sectors:

• PV/ESS inverter or PCS (power conversion system) design/application

• DC conversion systems or hybrid DC/AC platforms

• Battery system integration (LFP, NMC, etc.)

• Renewable energy + battery hybrid projects (e.g., PV + storage, wind + storage)

• Energy storage for grid services (FCR, FRR, peak shaving, islanding, etc.)

• Grid Knowledge

Practical understanding of the European electricity grid structure and standards is required. Familiarity with at least one national grid code in detail (e.g., Germany, Spain, Italy, France) is essential.

• Language Skills

Fluency in English is mandatory. Proficiency in at least one additional European language (e.g., Spanish, Italian, German) is highly preferred.

• Project Exposure

Prior experience collaborating with local European partners (e.g., EPCs, integrators, grid operators) on real storage or hybrid energy projects is strongly preferred.

• Learning Agility

Ability to quickly absorb technical knowledge related to PCS topologies, grid-forming/inertia modes, EMS dispatching logic, and safety standards. Adapt well to fast-paced international environments.

Preferred Traits:

• Familiar with European storage certification processes (e.g., VDE 4105/4110, CEI 0-16)

• Hands-on with technical tools such as CAD, PSCAD, PVSyst, DIgSILENT

• Experience in system commissioning, FAT/SAT, or site-based support is a plus
