We are seeking a highly motivated intern to take ownership of developing a spacecraft electrical power system simulation in Python-from design through verification-and to thrive in hands-on problem-solving during rapid prototyping. The ideal candidate is a rigorous systems thinker who proactively identifies, troubleshoots, and resolves modeling challenges across the full lifecycle of software development. You'll be embedded in a fast-paced, highly collaborative environment, working side-by-side with engineers to model, test, and refine a simulation of spacecraft power dynamics. You must be capable of quickly diagnosing and resolving technical issues in real-time and driving solutions that keep the project timeline on track.

Responsibilities

• Implement a Python-based Coulomb counter engine for tracking spacecraft battery charge and discharge.
• Develop load models for constant current, constant power, and constant resistance components.
• Implement common load metadata via class inheritance (e.g., name, UID, subsystem, parent load).
• Add composite load support for aggregating multiple load types.
• Track and report average power over time for each load.
• Model spacecraft power sources:
• Battery operating at voltage corresponding to its state of charge.
• Solar array following its IV curve at the current battery voltage.
• Integrate power source and load models into a time-step simulation loop.
• Export simulation results to CSV/JSON for external analysis and Grafana visualization.
• Participate in weekly reviews to test, validate, and improve model accuracy.

Qualifications

• Currently pursuing or recently completed a degree in Electrical Engineering, Computer Engineering, Physics, or related technical field.
• Familiarity with Python programming and object-oriented design.
• Basic understanding of electrical power systems and circuit theory (voltage, current, resistance, power).
• Strong problem-solving skills and ability to work independently with guidance.
• Good written communication for documenting code and simulation assumptions.

Benefits
In addition to compensation, York Space Systems is proud to offer a comprehensive benefits package including medical, dental, and vision insurance along with PTO and a 401K.
