Electrical Engineering Intern

About the Company

RadianX is a seed-stage hardware startup in the Bay Area developing a new power source for frontier applications.

About the Role

We're hiring an Electrical Engineering Intern to test our perovskite solar panels. This role involves characterization, building test fixtures, and assisting with prototype assembly. This is a paid internship with an immediate start, working directly with the engineering team.

Key Responsibilities

• Panel testing: Measure current-voltage (IV) curves of perovskite cells and modules on a solar simulator, in an indoor light chamber, and outdoors. Extract efficiency, fill factor, and maximum power.
• Calibration and methods: Maintain test station calibration for light intensity, spectrum, and uniformity. Assist in writing test procedures.
• Test automation: Extend scripts for source-measure units and multi-panel test rigs to increase testing efficiency.
• Data and reporting: Maintain the panel test database, compare results across production batches, and write up findings for the engineering team.
• Failure analysis: Design experiments to isolate causes of panel underperformance.
• Fixtures and prototypes: Design and 3D-print test fixtures. Assemble and debug power-management boards (MPPT and PMIC) for customer prototypes.
• Lab practice: Follow procedures for ESD, battery, and sample handling. Document setups for repeatability.

Requirements & Tech Stack

• Hands-on lab experience with a multimeter, oscilloscope, and bench power supply.
• Solid circuit fundamentals.
• Ability to read a schematic and solder.
• Python (or similar) for instrument control and data analysis.
• Careful measurement habits, including recording test conditions, repeating measurements, and questioning inconsistent results.
• Ability to write clear, short written summaries of tests and findings.

Qualifications

• Enrolled in, or recently graduated from, a bachelor's or master's program in electrical engineering, physics, materials science, or a related field.

Strong Signals

• Coursework or research in photovoltaics, semiconductor devices, or power electronics.
• Experience with source-measure units, solar simulators, or spectrometers.
• Hardware project-team experience (e.g., solar car, Formula SAE Electric, robotics team).
• CAD (SolidWorks or Fusion) and 3D printing.
• Embedded experience, including flashing and debugging microcontrollers and working with I²C devices.
• Familiarity with energy-harvesting power management ICs and maximum power point tracking (MPPT).
