Power Electronics Controls Engineer, Energy Storage

The role

You will lead the design and implementation of control systems for Battery Energy Storage Systems and mixed-asset energy sites. This involves designing control algorithms, developing digital twins, and leading hardware-in-the-loop testing.

What you will do

• Design and optimize advanced control algorithms for high-power BESS
• Develop bidirectional DC/DC and AC/DC control schemes
• Build high-fidelity Digital Twins of power stages and grid environments
• Architect and lead Hardware-in-the-Loop testing environments
• Collaborate with battery and systems teams to implement control strategies
• Partner with electrical, firmware, and thermal engineers to define the roadmap

Required qualifications

• MSc in Electrical Engineering with a specialization in Power Electronics Control Systems and 3+ years of relevant industry experience
• Deep theoretical and practical mastery of high-efficiency power conversion
• Expert in resonant topologies (LLC, CLLC, DAB) and advanced multi-level architectures (FC and ANPC)
• Proven ability to design robust closed-loop controllers (Bode, Nyquist, State-Space)
• Implement controllers on digital signal processors (DSPs) or microcontrollers
• Expert-level MATLAB/Simulink and PLECS
• Strong proficiency in C for real-time embedded systems
• Experience with Python for automation, scripting, and data analysis
• Self-driven attitude to navigate ambiguity in a fast-paced R&D environment

Nice to have

• PhD
• Familiarity with grid-interconnection codes (e.g., IEEE 1547, UL 1741)
