Job summary

Cowboy Space Corporation is building the hardware, automation, and measurement systems to study radiation effects on electronics. You will own reusable radiation test infrastructure—from circuit design to reproducible results—and contribute to a modular motherboard platform for heavy-ion testing across devices and campaigns.

This hands-on, on-site role requires collaboration with radiation effects engineers, avionics designers, and test facilities to extend capabilities for new components and

Qualifications

• A degree in electrical engineering, computer engineering, physics, or a related discipline, or equivalent practical experience.
• Hands-on experience testing electronic hardware under radiation, with an understanding of single-event effects and total ionizing dose.
• Experience designing, bringing up, and debugging PCB-based test hardware, including bias circuits, component interfaces, and electrical measurements.
• Ability to develop maintainable test automation and data-analysis software in Python or a comparable language.
• Practical experience with instruments such as source measure units, oscilloscopes, power supplies, and data-acquisition systems.
• Careful measurement and documentation habits: checking calibration and setup behavior, preserving raw data, investigating anomalies, and explaining the limits of a result.

Responsibilities

• Develop reusable test electronics. Design and bring up motherboards, device-specific daughterboards, bias and protection circuits, fixtures, and interfaces for component radiation testing.
• Document the interfaces so new devices can be tested without rebuilding the entire setup.
• Build reliable test automation. Develop software for instrument control, stimulus generation, electrical characterization, event logging, and data reduction.
• Make runs recoverable and preserve hardware, software, and instrument configurations alongside the measurements.
• Own measurement quality. Establish calibration and verification procedures for the electrical measurement chain.
• Characterize uncertainty, repeatability, noise, timing, and event-detection limits so the team can distinguish device behavior from test-system artifacts.
• Prepare and execute radiation campaigns. Develop procedures, perform readiness checks, and operate test setups for heavy-ion and other component radiation tests.
• Coordinate sample preparation, beam access, and facility interfaces with the relevant specialists.
• Make exposure and response data traceable. Confirm required beam and dosimetry information with facility staff, record exposure conditions and device operating states, and correlate those records with electrical measurements and observed events.
• Turn test runs into engineering evidence. Characterize devices before, during, and after exposure as required; investigate unexpected results; and deliver reproducible analysis, clear reports, and documented limitations for review with radiation effects and component engineers.
• Sustain the broader test capability. Improve related characterization benches, data-acquisition tools, fixtures, documentation, and checkout procedures. Use lessons from each campaign to reduce setup errors and make future testing easier to repeat.
