Lead Engineer Pv & Bess

Welcome to Alstra Energy - one of Sweden’s leading companies in solar power and energy storage! For over 10 years, we have been driving the industry forward, and yet we’re only just getting started.

We support companies, property owners, investors, and landowners across Sweden in reaching their sustainability goals and improving their profitability through solar energy, energy storage, and balancing services. As a full‑service provider, we take responsibility for the entire process — from planning and consulting to installation and maintenance.

About the role
The Lead Engineer is responsible for leading and coordinating the engineering scope of Solar PV and BESS projects throughout development, tendering, execution, and commissioning. The role ensures technically optimized, compliant, and commercially competitive project solutions.

You will report to the Head of Engineering and be part of a team of approximately 15 people, including Lead Engineers, Engineers, and Electrical Power Engineers.

Areas of responsibility:

• Lead the project’s Engineering team through tendering, execution, and commissioning of Solar PV and BESS projects, ensuring technical excellence and alignment with project objectives.

• Develop, review, and approve engineering deliverables, including site layouts, drawings, PVsyst simulations, technical specifications, and tender documentation.

• Ensure that all engineering solutions are optimized, constructible, compliant with standards and regulations, and commercially competitive within the EPC framework.

• Coordinate cross‑functional engineering activities across internal disciplines, external consultants, and subcontractors, including RFQ preparation, technical evaluations, supplier assessments, and design optimization.

• Ensure Engineering delivers according to schedule to uphold all project payment milestones and maintain overall project progress.

• Develop, implement, and improve internal engineering processes to optimize work hours, strengthen quality, and enhance consistency across projects.

Who you are
You are a technically strong and experienced engineer with a background in solar energy and preferably also energy storage. You thrive in a leading role where you combine technical expertise with structure, coordination, and clear communication.

We also believe you have:

• Bachelor’s or Master’s degree in Electrical Engineering, Energy Systems, Renewable Energy Engineering or equivalent.

• 5–7 years of relevant experience in Solar PV engineering.

• Experience with BESS or hybrid solutions (strongly preferred).

• Experience leading technical activities during tendering and execution phases.

• Experience coordinating multidisciplinary teams and external consultants.

• Strong skills in PVsyst, AutoCAD, PVCase, or similar tools.

• Understanding of LV/MV systems, grid connection requirements, SCADA/PPC, and relevant standards.

• Strong communication skills in English.

As a person, you are structured, analytical, and solution‑oriented. You naturally take technical ownership, prioritize effectively, and manage multiple stakeholders with confidence. You combine technical accuracy with commercial awareness and enjoy both independent work and driving cross‑functional collaboration.
