## Description

We're hiring a Test Engineer to own day-to-day operation of the solar simulator and lead the characterization and validation testing that feeds directly into our product development. This is a hands-on role for someone who likes working with real hardware, high-flux optics, and high-temperature systems , and who gets energized by the fact that the data they generate actually drives design decisions.

Key Responsibilities:

- Plan, set up, and execute test campaigns on the solar simulator, including thermal receiver characterization, material testing, and sub-system validation

- Design and build test fixtures, instrumentation setups, and data acquisition systems to capture high-quality experimental data

- Operate and maintain the simulator and supporting lab infrastructure , lamp arrays, optics, cooling, controls, and safety systems

- Perform flux mapping, spectral characterization, and calibration to ensure test conditions are well-understood and repeatable

- Instrument test articles with thermocouples, pyrometers, flow meters, flux sensors, and related diagnostics

- Develop data acquisition and control scripts (LabVIEW, Python, or similar) and automate repetitive test sequences

- Analyze test data, identify anomalies, and communicate results clearly to R&D, engineering, and leadership stakeholders

- Partner closely with design engineers to translate test findings into design improvements

- Write test plans, procedures, and reports; maintain rigorous records of configurations, calibrations, and results

- Enforce and continuously improve lab safety practices for high-flux, high-temperature, and high-voltage work

- Support troubleshooting and root-cause investigations on prototype hardware

Required Qualifications:

- Bachelor's degree in Mechanical, Aerospace, Electrical, or a related engineering field

- 3+ years of hands-on test engineering experience in a lab or prototype environment

- Experience designing and executing test plans, including instrumentation selection and test fixture design

- Proficiency with data acquisition tools (LabVIEW, Python, MATLAB, or similar) and common lab instrumentation

- Strong understanding of heat transfer, thermodynamics, or thermal-fluid systems

- Comfort working with high-temperature, high-voltage, or otherwise hazardous equipment, and a demonstrated safety-first mindset

- Clear technical writing and the ability to communicate findings to technical and non-technical audiences

Preferred Qualifications:

- Experience with solar simulators, high-flux testing, or other high-intensity optical systems

- Familiarity with thermal receivers, heat exchangers, or high-temperature storage materials

- Experience calibrating optical or thermal instrumentation (pyrometers, flux gauges, radiometers)

- Background in mechanical fabrication, machining, or hands-on prototype assembly

- Previous work in a fast-moving hardware startup environment

Additional Information:

What We Offer:

- Competitive salary and equity options

- Comprehensive benefits package, including health, dental, and retirement plans

- A dynamic work environment that fosters creativity and innovation

- Opportunities for professional growth and development in a rapidly evolving industry

- Relocation assistance
