Full Job Description
We are seeking an experienced Power Controls Engineer to join the satellite power systems team. You will be responsible to develop models and state estimation algorithms for satellite power system including solar arrays, power conversion, and energy storage.

You will work closely with a world-class team of engineers and business leaders to build/integrate models for satellite power system including battery model (equivalent-circuit, aging, physics-based) and solar array degradation model. You will also work on state estimation algorithms such as battery state of charge, battery state of health, and state of power of a battery which can be deployed on embedded or cloud platforms. You will be responsible for overall modeling & algorithm design, deployment, and test verification.

You will work with large datasets to evaluate health of battery over life and track accuracy of models and performance of system to vehicle requirements. You will also work on development and implementation of power system fault detection and mitigation.

Export Control Requirement: Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Key job responsibilities

- Develop and integrate battery models (equivalent-circuit, aging, physics-based)

- Develop, deploy, and verify state estimation algorithms such as battery state of charge, battery state of health, and state of power of a battery.

- Develop and integrate power system models including solar arrays, power conversion, and energy storage.

- Develop and implement satellite power system fault detection and mitigation.

BASIC QUALIFICATIONS

- Bachelor's degree in a related field

- 5+ years experience in simulation, modeling, and state estimation for lithium ion battery packs.

- 2+ years experience and working knowledge of Matlab or Python to extract, process, and store information from large datasets.

PREFERRED QUALIFICATIONS
