Modeling & Simulation Engineer

Modeling & Simulation · Seattle, Washington

First Mode is a creative engineering company solving the toughest problems on and off the planet, with the goal of having an outsized impact on the world around us. We build the barely possible.  

From our state-of-the-art manufacturing and production facilities in Seattle and Perth, we design and deliver resilient, reliable solutions for the most demanding and constrained frontiers in existence. In the last year our engineers built a 2MW hydrogen fuel cell and battery powerplant to retrofit a three-story, 300-metric-ton-capacity diesel haul truck; designed the power source and refueling system for the world’s first endurance race vehicle to be powered by liquid hydrogen; and delivered spaceflight hardware headed 370 million kilometers from Earth to asteroid 16 Psyche. 

While each project is unique, we typically meld together robotics, automation, systems engineering, modeling and simulation, and advanced fabrication to create a new future across many industries. If you have exceptional talent and a vision for the future, we want to talk. 

First Mode is seeking to add new members to our engineering team focused on modeling and simulation. We’re looking for individuals who have passion, experience, and hard-won lessons in the art of model development. You enjoy diving into new platforms and technologies to figure out how they work and appreciate the thrill of seeing your work bring a physical system to life. This role is open to engineers from Engineer level through to Senior Engineer.
