Über diese Powertrain Architect — Hybrid-Electric Propulsion Stelle bei Archer
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.
THE ROLE
As Powertrain Architect, you will evaluate and size the hybrid-electric propulsion system for a next-generation eVTOL — spanning combustion engine selection, electromagnetic sizing, thermal management, and battery behavior — and contribute the resulting models into Archer's broader vehicle-level sizing and optimization stack. You will work closely with the Vehicle and Structures Architects to close the powertrain within the overall vehicle concept.
WHAT YOU'LL DO
- Evaluate and trade hybrid-electric powertrain architectures (series, parallel, turbo-electric), integrating battery energy storage and electric motors/inverters, with a turboshaft-driven generator as one of the configurations considered.
- Size electric motors and generators from first principles, validating and refining designs with electromagnetic solvers as needed.
- Size the thermal management system architecture — heat exchangers, ducting, and coolant line routing — for all major powertrain components, using thermal/CFD tools as needed.
- Generate performance and efficiency maps for electric motors and generators across the operating envelope.
- Model battery charge and discharge behavior (C-rates, thermal behavior, degradation) to inform sizing and duty-cycle decisions.
- Estimate thermal limits and duty cycles for motors, inverters, and batteries across representative mission profiles.
- Build powertrain models suitable for integration into Archer's larger vehicle-level MDO stack, supporting the vehicle-level sizing and performance predictions led by the Vehicle Architect.
- Collaborate with the structures and vehicle architects on packaging, weight, and integration of the full powertrain stack.
WHAT YOU'LL NEED
- Background in hybrid-electric, turbo-electric, or conventional turbine aircraft propulsion (aerospace or adjacent high-power industries).
- Some background in optimization, including multidisciplinary design optimization (MDO), is necessary.
- Experience in at least two of the following three areas is required: electromagnetic sizing of motors/generators; thermal management system sizing; battery modeling (equivalent-circuit or electrochemical).
- Proficiency with electromagnetic design tools such as ANSYS Maxwell, Motor-CAD, JMAG, or similar is desired.
- Proficiency with thermal/CFD design tools such as ANSYS Icepak, Fluent, or similar is desired.
- Strong Python proficiency for powertrain modeling and trade studies is strongly preferred.
- Turboshaft/turbine integration experience is desired.
