Job Title: Thermophotonic (TP) Device Engineer
Location: Bangalore, India
Job Type: Full-Time | In office
Experience: 3–10 years

Role Overview
We are looking for a highly skilled Thermophotonic (TP) Device Engineer to work on design, fabrication, and optimization of high-efficiency PV and thermophotonic energy conversion devices. This role involves full-stack semiconductor 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
Device Engineering & Fabrication
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.

Characterization, Testing & Simulation
Conduct optical, electrical and material characterization:
IV, CV, EQE/IQE, electroluminescence, photoluminescence
Hall mobility, carrier lifetime, AFM, SEM, TEM, XRD
Thermal cycling and failure/degradation analysis
Utilize advanced simulation tools:
TCAD Sentaurus, Silvaco, Lumerical, COMSOL, LightTools
MATLAB/Python for analytical modeling
Analyze thermal-radiative coupling
