Thermophotonic (TP) Device Engineer
Role Overview

We are looking for a highly skilled Thermophotonic (TP) Device Engineer to work on design, fabrication, and optimization of high-efficiency thermophotonic energy conversion devices. This role involves full-stack device development, including epitaxial growth, wafer processing, characterization, packaging, and thermal-photonic performance modeling. Experience with III V semiconductor materials and device physics is strongly preferred.
Key Responsibilities
Design and develop high-efficiency photovoltaic and thermophotonic devices, including multijunction III-V structures, GaSb/InGaAs cells, spectral-selective energy converters, and photonic energy amplifiers.
Perform epitaxial growth using MOCVD / MBE, including reactor operation, precursor selection, growth recipe optimization, and in-situ monitoring systems (RHEED, pyrometry, interferometry).
Lead semiconductor wafer-level processing:
Photolithography
Wet dry etching (RIE, ICP)
Metallization and ohmic contact engineering




Surface passivation and anti-reflection coatings
Thin-film and dielectric deposition (ALD, PECVD, sputtering, evaporation)
Develop optical and photonic structures including selective emitters, photonic crystals, interference filters and dielectric mirrors for spectral control.
Oversee device packaging, thermal interface engineering, and interconnect architecture for high-temperature operation.
Collaborate with system engineering teams to integrate devices with thermal emitters, optical coupling assemblies, power electronics, and energy storage interfaces.
Support cooling, heat extraction thermal management for high-temperature applications.
Evaluate scaling readiness, fabrication partnerships and production.
Required Skills Qualifications
Bachelor s/Master s/PhD in Semiconductor Physics, Materials Science, Electrical Engineering, Nanotechnology, Photonics, or related field.
3 10 years of experience in semiconductor devi
