Electrical Engineering Intern, Test and Characterization

RadianX; Redwood City (CA); On-site; USD 34,000 - 44,000; Part time

Job summary

RadianX is seeking an electrical engineering intern to test perovskite solar panels and develop test fixtures and automation. You will perform IV characterization on cells and modules using our solar simulator and outdoor tests, contributing to customer-ready data.

This paid internship starts immediately at our Redwood City site, with part-time schedules acceptable. You will collaborate with a small engineering team and gain hands-on PV testing experience.

Qualifications

• Enrolled in or recently graduated in electrical engineering, physics, or materials science.
• Hands-on lab experience with a multimeter, oscilloscope and bench power supply.
• Ability to read a schematic and solder.
• Python or a similar language for instrument control and data analysis.
• Clear, concise written summaries of tests and results.

Responsibilities

• Panel testing: measure IV curves of perovskite cells and modules with a solar simulator.
• Calibration and methods: maintain light intensity, spectrum and uniformity; write test procedures.
• Test automation: extend scripts for SMU and multi-panel tests to reduce manual steps.
• Data and reporting: maintain test database and compare results across batches.
• Failure analysis: design small experiments to isolate underperformance causes.
• Fixtures and prototypes: design 3D-printed fixtures and assemble power-management boards.
• Lab practice: follow ESD and handling procedures and document setups for repeatability.

About the company

RadianX is a seed-stage hardware startup based in the Bay Area building a new source of power for frontier applications, from robotics and connected edge devices to the built environment. Our technology turns everyday surfaces into power sources. We are a small, focused team: an exited founder, NASA engineers, and materials scientists who have spent their careers turning emerging technology into products and scaling the operations behind them. Our first products are already in customers' hands.

Who we hire

Most of what we do has not been done before. The people who do well here have built something they can point to, whether a test setup in a research lab or a board they designed and brought up for a project team. They hold a high standard for their own work, which in a test role means data that someone else can reproduce.

The role

We're hiring an electrical engineering intern to test our perovskite solar panels. Most of the work is characterization: measuring how cells and modules perform on our solar simulator, under indoor light and outdoors, and making sure the results are accurate enough to share with customers. The rest is building the fixtures and test automation that make that work faster, and helping assemble prototypes for customer programs.

This is a paid internship with an immediate start, working directly with our engineering team.

What you'll do

• Panel testing: Measure current-voltage (IV) curves of perovskite cells and modules on our solar simulator, in our indoor light chamber and outdoors, and extract efficiency, fill factor and maximum power.
• Calibration and methods: Keep the test stations calibrated for light intensity, spectrum and uniformity, and help write the test procedures behind our product specifications.
• Test automation: Extend the scripts that run our source-measure units and multi-panel test rig, so that more panels are tested with fewer manual steps.
• Data and reporting: Maintain our panel test database, compare results across production batches, and write up findings for the engineering team.
• Failure analysis: Design small experiments that isolate why a panel underperforms, for example whether a low fill factor comes from interconnect resistance or from the cell itself.
• Fixtures and prototypes: Design and 3D-print test fixtures, and assemble and debug the power-management boards (MPPT and PMIC) used in customer prototypes.
• Lab practice: Follow our procedures for ESD, battery and sample handling, and document your setups so that others can repeat your measurements.

What you'll bring

• Enrolled in, or recently graduated from, a bachelor's or master's program in electrical engineering, physics, materials science or a related field.
• Hands-on lab experience with a multimeter, oscilloscope and bench power supply.
• Solid circuit fundamentals, and the ability to read a schematic and solder.
• Python or a similar language for instrument control and data analysis.
• Careful measurement habits: you record test conditions, repeat measurements and question results that do not make sense.
• Clear, short written summaries of what you tested and what you found.
  

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, such as a solar car, Formula SAE Electric or 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).
  

Why join

• Learn perovskite photovoltaics and low-power energy harvesting on real hardware, working directly with the engineers who design our panels and power electronics.
• Help build the test methods for a new class of energy-harvesting hardware.
• Your measurements go directly into the data we share with customers and into our decisions on product quality.
