Senior Power Systems Engineer

£65-80k / Hybrid - London

IONATE is a deep technology scale-up building the technology backbone for smart grids. We are seeking a Senior Power System Engineer to take ownership of power system modelling, leading projects from early-stage concept to commercial deployment in the field.

With a strong focus on power systems development, high-granularity data analysis and grid modelling, you will play a central role in leading or participating in design reviews and technical discussions. You will bring a rigorous engineering mindset, combining innovative thinking with sound technical reasoning to solve complex challenges.

In addition, you will support business development, project execution, and test activities, helping to ensure that all these are completed within schedule and budget.

What you will do:

• Develop and maintain high-fidelity power system models to support grid analysis, requirements definition, and product development.
• Perform power system simulations and EMT simulations including load flow, short-circuit and fault analysis, transient stability, fault-ride through, and harmonic propagation studies.
• Conduct detailed data analysis to evaluate network behaviour, power quality, dynamic performance, and overall system reliability.
• Lead technical design reviews and provide engineering guidance across cross-functional teams.
• Contribute to IONATE’s product architecture definition and the integration of our solution into electrical networks, ensuring compliance with applicable grid codes and regulatory standards.
• Collaborate closely with hardware, software, transformer, and control engineers to validate system-level performance from simulation through to field deployment.
• Provide technical input to business development activities, including feasibility assessment, technical proposals, and customer engagements.
• Produce clear, structured technical documentation of methodologies, assumptions, analysis, and results to support internal governance and external certification processes.
