Fractional CTO / Technical Co-founder

Full Spectrum Imaging seeks a Fractional CTO to drive technical development of IDIA, a Randomised Foil Mask and Compressed Sensing reconstruction system that adds spectral information to existing X-ray detectors. This role involves leading prototype development from TRL 3 to validation, working with government partners across NIH, DHS, and NSF.

This is an equity-only founder-level position until first government contract or partnership revenue closes. The ideal candidate combines technical expertise in X-ray physics with entrepreneurial drive to build a hardware-software solution for medical, security, and industrial imaging applications.

• Lead design of Randomised Foil Mask including material selection and manufacturing path
• Direct Compressed Sensing reconstruction algorithm development with consulting experts
• Own development and execution of comprehensive test plans
• Build prediction-chain software pipeline using SpekPy, NIST data, and detector models
• Serve as technical voice in proposals and customer engagements
• Shape technical narrative across government agencies and OEM partners

• Strong technical aptitude in X-ray or CT physics including tube spectra and reconstruction methods
• Experience with Compressed Sensing theory and implementation
• Background in hardware integration or detector systems
• Entrepreneurial mindset with willingness to work for equity initially
• Ability to work 5-10 hours per week remotely in US timezone
• PhD student, postdoc, or early-career scientist/engineer preferred
