Power Systems Engineer/Technology Consultant

  • Full Time
  • London

Do you want to be involved in positively disrupting the energy sector and leading the transition to a low carbon energy future? If you’re up for the challenge and have the power systems engineering skills to make it happen, join us!


Reactive Technologies is a highly innovative (150+ patents granted), industry-leading, energy tech company. Reactive focuses on offering unique measurement and analytics services for Transmission and Distribution System Operators (TSOs and DSOs) and an enhanced Power Purchase Agreement (PPA) for renewable asset owners. To learn more about the company, please visit: www.reactive-technologies.com


As a start-up, we are agile, have a flat structure and reward good results. We offer a competitive salary, health and life insurance, pension and a modern, centrally located London office with flexibility offered for home workers.


Reactive Technologies is approaching energy system challenges in a very different way – applying innovative signal processing and data science technology to solve the greatest energy system challenges and redefine the status quo. This business unit offers three main services:

  • Measurement: Technology that measures critical grid metrics. We are the first company to offer accurate measurement of system inertia, allowing us to show TSOs how inertia impacts frequency margins in real time and enabling System Planners to predict future risks more accurately. We are actively building our product portfolio to drive change in the system operations realm.
  • Control: Building on real time measurements, we can detect and help TSOs respond to events faster and in a more dynamic way than ever before.
  • Analysis: We use our power systems, signal processing and data science expertise to understand and resolve challenges facing modern TSOs, DSOs and Independent Power Producers (IPPs).
