Security Engineer

Company Description

Voltus is the leading platform connecting distributed energy resources to electricity markets, delivering less expensive, more reliable, and more sustainable electricity. Our commercial and industrial customers and grid services partners generate cash by allowing Voltus to maximize the value of their flexible load, distributed generation, energy storage, energy efficiency, and electric vehicle resources in these markets.

Job Description

Operating as a virtual power plant, our platform delivers the grid of the future today. Our software coordinates and dispatches actual megawatts across thousands of grid-connected sites within regulated wholesale energy markets, managing real financial settlements for the customers behind them. In this position, you will secure real-time energy dispatches, thousands of integrations, and live telemetry for critical infrastructure where system availability and data integrity directly affect physical power distribution and real people.

In this role, you will manage security holistically and make critical, actionable decisions daily, with the independence to shape the program's evolution. You will design and secure software to safeguard virtual critical energy infrastructure, directly enabling the climate energy transition. Your responsibilities will cover a wide range of challenges: establishing our detection and response capabilities from their foundations, leading end-to-end incident response, transforming vulnerability noise in a large monorepo into actionable insights for engineering teams, and operating on both sides of the AI frontier, utilizing agentic tools to amplify your output while establishing the guardrails the company will adopt.
