Senior Material Science and Growth Engineer

About the role

Besxar Space Industries is developing off‑Earth semiconductor foundries. The Senior Material Science and Growth Engineer will lead the development of growth processes and hardware for Fabships, turning ambiguous mission requirements into repeatable, manufacturable semiconductor recipes.

Key responsibilities

• Lead R&D of semiconductor material growth and epitaxial processes, including recipe development, trade studies, and integration across deposition sources, chambers, and tooling.
• Design and execute experiments to understand growth dynamics, characterize materials (SEM, XRD, spectroscopy), and feed results back into process improvements.
• Operate, maintain, and improve advanced vacuum and thin‑film deposition systems (MBE, CVD, PVD, ALD, sputtering, evaporation).
• Translate mission and system requirements into manufacturable growth processes that balance performance, yield, throughput, cost, and schedule.
• Build the foundational knowledge base – recipes, process windows, characterization standards, and DOE practices – for a new manufacturing platform.

Required profile

• Master's or PhD in Materials Science, Electrical Engineering, Semiconductor Physics, or related field, or equivalent practical experience.
• 5+ years of progressive experience in semiconductor materials growth, taking processes from experimentation to repeatable manufacturing.
• Hands‑on experience with vacuum systems and thin‑film deposition technologies.
• Strong experimental mindset and ability to work autonomously in ambiguous, fast‑paced environments.

Required skills

• Epitaxy, crystal growth, thin‑film deposition (MBE, CVD, PVD, ALD, sputtering, evaporation).
• Materials characterization techniques: SEM, XRD, spectroscopy, AFM, TEM, XPS, photoluminescence, ellipsometry, RHEED, Hall transport measurements.
• Design of Experiments (DOE), statistical process control, data‑driven process optimization.
• Experience with vacuum system operation, leak control, and in‑situ diagnostics.
