System Engineer PV & BESS - Spain

¡Hola a todos y bienvenidos a Sungrow! We are so excited to share this opportunity with you — a role that sits right at the intersection of cutting-edge renewable energy technology and the digital backbone that keeps it all running safely and smartly.

As our System Engineer PV & BESS based in Spain, you will be the technical heartbeat connecting our solar and battery energy storage systems with the wider digital world. Curious what that looks like day to day? Here we go:

• You will act as the primary technical interface with external SCADA, PPC, and EMS vendors — defining and validating communication architectures that keep our systems talking to each other seamlessly.
• You will support engineering activities, FAT/SAT testing, and commissioning — ensuring industrial communication protocols such as Modbus (RTU/TCP), IEC 61850, IEC 60870-5-104, and DNP3 are correctly implemented across projects.
• You will analyze customer technical specifications related to cybersecurity and IT/OT architectures, translating complex requirements into clear equipment definitions and configurations.
• You will assess cybersecurity risks across our systems and coordinate mitigation actions with both internal teams and external stakeholders — keeping our projects safe, compliant, and resilient.
• You will monitor and interpret applicable cybersecurity standards and regulations — including IEC 62443, ISO 27001, and grid operator requirements — ensuring full product compliance and supporting audits and conformity assessments.
• You will prepare and maintain high-quality technical documentation — from network architectures and communication matrices to cybersecurity guidelines — while also supporting presales activities by reviewing and responding to technical specifications.

Alright, alright — that sounded pretty exciting, didn't it? Now, to truly thrive in this role and grow with us for the long run, your background should look something like this:

• You hold a degree in Electrical Engineering, Telecommunications, Networks, Industrial Automation, or a closely related field — and you bring proven hands-on experience in SCADA and control system integration.
• You have solid experience working with PPC/EMS environments and interacting with external technology vendors and end customers in real-world project settings.
• You are fluent in industrial communication protocols (Modbus, IEC 61850, DNP3, IEC 60870-5-104) and comfortable navigating IT/OT architectures, industrial networking (Ethernet, TCP/IP, VLANs, firewalls), and OT cybersecurity principles.
• You have a good understanding of network segmentation, access control, and secure remote access — and you are familiar with industrial cybersecurity standards such as IEC 62443 and ISO 27001.
• Experience with inverters, PCS, and BESS technologies is a strong plus, as is knowledge of utility or grid operator cybersecurity requirements.
• You communicate effectively in Spanish and English at a C1 level; any additional European languages are a welcome bonus.
• Experience with inverters, PCS, and BESS technologies is a strong plus, as is knowledge of utility or grid operator cybersecurity requirements.

At Sungrow's Spain team, you won't just be another engineer — you'll be a key player in one of the most dynamic and purpose-driven corners of the energy transition. Our local team works at the forefront of solar and battery storage deployment across the Iberian Peninsula and beyond, combining global expertise with a close-knit, collaborative spirit.

We offer a role with real technical depth and variety, the chance to work on meaningful large-scale renewable projects, and the support of a global greentech leader with strong roots in inverter technology, battery storage, and EV charging solutions. We believe in growing our people as fast as we grow our technology — and in Spain, that means being part of something truly exciting.
