We're reinventing aircraft from the engine forward. Backed by Y Combinator and a16z.
About the role
Build and maintain time-domain models of the HV and LV power system, from component models (batteries, generators, inverters, DC-DC converters, chargers, actuators) up to the full aircraft Analyze bus stability, including the interaction between source and load impedances and the negative incremental impedance of tightly regulated converter loads Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- BS, MS, or PhD in electrical engineering with a focus on power systems or power electronics
- 5+ years of experience modeling and analyzing power systems with power electronic sources and loads, e.g. aircraft, electric vehicle, ship or DC microgrid power systems
- Proficiency in time-domain simulation of power electronic systems (Simulink/Simscape Electrical, PLECS, or equivalent) and in scripting (Python, MATLAB)
- Strong understanding of DC bus stability: small-signal analysis, impedance-based stability criteria (e.g. Middlebrook) and constant power load behaviors
- Experience with both switching and averaged converter models, and with choosing the model fidelity each analysis needs
- Working understanding of batteries, electric machines, motor drives and converter control loops

Astro Mechanica is looking for a Senior Electrical Engineer to model the electrical power system of our aircraft. The aircraft has an HV bus (e.g. 800V DC) and a low voltage DC bus. These buses connect HV batteries, 1 MW-class generators and engine loads, inverters, DC-DC converters, chargers and actuators, and the loads vary widely across the mission. You will build...
