Sensors Intern
About The Position
WindBorne Systems is supercharging weather models with a unique proprietary data source: a global constellation of next-generation smart weather balloons targeting the most critical atmospheric data. We design, manufacture, and operate our own balloons, using the data they collect to generate otherwise unattainable weather intelligence. Our mission is to eliminate weather uncertainty, and in the process help humanity adapt to climate change, be that predicting hurricanes or speeding the adoption of renewables. We are building a future in which the planet is instrumented by thousands of our microballoons, eliminating gaps in our understanding of the planet and giving people and businesses the information they need to make critical decisions. The founding team of Stanford engineers was named Forbes 2019 30 under 30 and is backed by top investors including Khosla Ventures. WindBorne's balloons carry custom meteorological sensors that measure temperature, humidity, pressure, wind, and altitude across some of the harshest environments on Earth. Every sensor we fly is built, calibrated, and validated in-house. This role sits at the center of that pipeline: you'll own sensor manufacturing processes, constantly improve our calibration infrastructure, and dig into flight data to understand how our sensors perform in the atmosphere. When something drifts, biases, or breaks, you'll be the one figuring out why and fixing it. You'll design and fabricate tooling and bring calibration systems to production readiness — and the sensors you build and calibrate fly on every balloon in the constellation. We've quadrupled the size of our balloon constellation in the last year, and you'll be essential as we continue to scale at the same pace.
Requirements
- Bachelor's degree or higher in Physics, Meteorology, Electrical Engineering, Mechanical Engineering, or a related STEM field
- Hands-on prototyping skills: soldering, CAD, machine shop, 3D printing, laser cutting
- Can rapidly prototype, iterate, and push things to production
- Strong physics intuition and first-principles thinking
- Python proficiency for data analysis and scripting
- Linux/bash comfort — ability to navigate systems, run scripts, and work in the terminal
- Data and statistical analysis skills
- Ability to work with LLMs to accomplish software tasks
- High agency: can own projects end-to-end with minimal oversight
Nice To Haves
- Experience with temperature, pressure, or humidity chambers
- Familiarity with low-temperature systems
- PCB design or modification experience
- Sensor calibration methods in any capacity
- Background in experimental physics or instrumentation
Responsibilities
- Relentlessly optimize meteorological sensor manufacturing processes
- Design and fabricate tooling and fixtures for soldering, conformal coating, and assembly workflows
- Bring calibration systems to production readiness and improve existing calibration infrastructure, which includes temperature, pressure, and humidity chambers
- Develop new measurement tools and methods for sensor characterization
- Investigate sources of bias, systematic error, and contamination, and eliminate them
- Help with sensor R&D and test new sensing concepts in flight
- Analyze sensor flight performance data: sift through data, categorize trends, make clear plots, and present findings
