Mass Properties Engineer

Archer is an aerospace company based in San Jose, California building an all-electric vertical takeoff and landing aircraft with a mission to advance the

Benefits

of sustainable air mobility. We are designing, manufacturing, and operating an all-electric aircraft that can carry four passengers while producing minimal noise. Our sights are set high and our problems are hard, and we believe that diversity in the workplace is what makes us smarter, drives better insights, and will ultimately lift us all to success.

We are dedicated to cultivating an equitable and inclusive environment that embraces our differences, and supports and celebrates all of our team members. Join Archer Aviation's Mass Properties team and play a critical role in bringing electric vertical takeoff and landing (eVTOL) aircraft from concept to certified reality. As a Mass Properties Engineer, you'll be the backbone of our weight and balance programs—ensuring every gram counts as we push the boundaries of sustainable urban air mobility.

This isn't a desk job. You'll get hands-on with actual aircraft, manage data that directly influences flight performance, and see your work take to the skies.

What You'Ll Do

Own Critical Data Programs Lead day-to-day execution of mass properties programs across multiple aircraft platforms Build and maintain the master database tracking weight, CG, and inertia for all aircraft variants—the single source of truth for the entire engineering organization Bridge Design and Reality Partner with design, structures, and systems teams to validate mass assumptions and drive weight optimization decisions Manage the evolution of mass data from early estimates through measured flight hardware—you'll track every component's journey Get Hands-On with Aircraft Conduct aircraft inspections and lead weighing operations—this role gets you on the factory floor and around actual aircraft Execute weight and balance audits that ensure flight safety and performance targets Support Certification & Compliance Prepare documentation and analysis supporting FAA certification activities Ensure all mass properties data meets regulatory

Requirements
