Estes develops and manufactures exceptional zero-emission power systems that unlock true scale and performance for the electrification of the commercial vehicle and equipment markets. Estes will democratize electrification by enabling powertrain solutions at better cost and performance than diesel solutions, for both high-volume established OEMs making thousands of vehicles per year, and industry newcomers making next generation electrified vehicles and equipment.
Here's the ugly truth. Approximately 3.9 million barrels of diesel fuel (equal to 5.8 Terawatt-hours of energy) are consumed every day across the United States, mostly by commercial vehicles and equipment. That's 1.66 megatonnes of CO2 GHG emissions every day. That's 353 kilotonnes of NOx and 9.92 kilotonnes of SOx gases emitted, poisoning our people and planet, every day.We exist to move the needle on transitioning a century old diesel burning industry to electric.
What are our principles to solve this problem? Simple.
The Impact You'll Make / About the Role : As our first dedicated Test Engineer, you will architect, build, and lead all aspects of product testing – from equipment selection to data-driven design feedback – laying the foundation of a world-class validation organization. This highly visible and impactful role requires a hands-on engineer eager to establish our lab infrastructure, develop robust test methodologies from the ground up, and drive the rigorous validation of our high-voltage battery packs. You will play a critical role in ensuring the safety, performance, and reliability of our products from early concept through launch and beyond, with significant opportunity for professional growth and future team leadership.
