Senior Staff Applications Engineer - Spark

Crusoe is on a mission to accelerate the abundance of energy and intelligence. As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster.

We're in the midst of the greatest industrial revolution of our time. The demand for AI compute is boundless, and power is a bottleneck. We're solving that — with an energy-first approach that makes AI infrastructure better for the world and faster for the people innovating with AI.

We're looking for problem-solving, opportunity-finding teammates with a sense of urgency, who believe in the scale of our ambition and thrive on a path not fully paved — people who want to grow their careers alongside a team of experts across energy, manufacturing, data center construction, and cloud services.

If you want to do the most meaningful work of your career, help our customers and partners advance their AI strategies, and be part of a high-performing team that believes in each other, come build with us at Crusoe.

We are seeking a Senior Staff Applications Engineer to own how Spark answers the question of technical fit. You will build and maintain the evaluation framework that determines whether a site, partnership, or commercial opportunity is viable for the Spark modular data center (MDC) and Spark-Liquid (DLC) product lines, and you will support the Energy Development Group (EDG), business development, and partner teams as they apply it. When an opportunity is undefined, unconventional, or contested, you are the Spark team's point of contact, the person who answers the hard product questions and delivers the technical verdict.

Spark is on a path to deploy hundreds of megawatts of modular capacity, and every megawatt of it begins as an unqualified site on a map. Your judgment about where this product can be applied, not the design of the product itself, is what converts that pipeline into deployable capacity.

• Experience with modular, containerized, or prefabricated infrastructure product lines.

• Familiarity with agency certification and AHJ coordination for modular electrical equipment across varied jurisdictions.

• Deep familiarity with energy development, interconnection processes/queues, and behind-the-meter site configurations.

• You prefer purely theoretical design work over applied, rapid feasibility assessments.

• You require complete data and fully finalized engineering designs before making a technical recommendation.

• You struggle to communicate complex engineering tradeoffs to commercial partners or executive stakeholders.
