# Senior / Principal Computational Materials Scientist (Xora Portfolio Company)

> Xora Innovation · San Diego, United States (Hybrid) · Full-time · Posted 2026-10-06

**Workplace:** hybrid

**Department:** XVL

## Description

**ABOUT THE ROLE**

Elemynt is building an AI-native platform for discovering and qualifying materials and precursors for advanced semiconductor manufacturing. We are hiring two computational scientists to leverage our physics-based simulation stack — from atomistic chemistry through process-scale behavior — to fuse it with machine-learned models in a way that shortens the path from candidate molecule to qualified process in semiconductor manufacturing.  This is a hands-on technical role in a small team. You will pick the methods, build the workflows, run the calculations, and be accountable for whether the predictions hold up against fab data. 

**WHAT YOU WILL DO**

-   Model precursor chemistry, surface reactions, and thin-film growth and etch mechanisms using DFT (periodic and molecular) ranking pathways for ALD, ALE, CVD, and epitaxy processes. 
-   Build, train, and fine tune machine-learned interatomic potentials on DFT data and deploy them in large-scale MD and kinetic simulations. 
-   Run classical and reactive MD (LAMMPS, ReaxFF) for film nucleation, defect evolution, interface formation, and plasma–surface interaction. 
-   Bridge atomistic results into continuum and process-level models (for example; Sentaurus Process, Victory Process, custom kinetic Monte Carlo) to predict conformality, selectivity, throughput, and device-relevant film properties. 
-   Design simulation campaigns that feed active-learning and generative models — you will define what is computed, at what fidelity, and why. 
-   Work directly with customer process engineers at IDMs, foundries, OEMs, and materials suppliers to validate predictions against experimental and fab data. 
-   Establish reproducible, automated simulation infrastructure (workflow managers, HPC/cloud orchestration, data provenance). 

**WHAT WE ARE LOOKING FOR**

**Required**

-   PhD in chemistry, physics, materials science, chemical engineering, or a closely related field. 
-   5+ years of post-PhD industry experience at a semiconductor IDM, foundry, equipment OEM, materials or precursor supplier, or an EDA / molecular-modeling software company. 
-   Demonstrated production use of DFT (VASP, Quantum ESPRESSO, CP2K, QuantumATK, Gaussian, ORCA, or equivalent) on semiconductor-relevant chemistry — deposition, etch, doping, interfaces, or defects. 
-   Hands-on experience with molecular dynamics, including force-field or MLIP selection, validation, and interpretation. 
-   Working familiarity with process simulation / TCAD (for example; Sentaurus, Victory, or equivalent) and an understanding of how atomistic results translate to process outcomes. 
-   Strong Python; comfortable building and automating workflows (ASE, pymatgen, AiiDA, FireWorks, or similar). 
-   Track record of predictions that changed an experimental or engineering decision. 

**Strongly preferred**

-   Experience training or fine-tuning MLIPs / universal potentials and knowing when they fail. 
-   Kinetic Monte Carlo or microkinetic modeling of surface processes. 
-   Exposure to plasma chemistry modeling (etch, PEALD). 
-   Publications or patents in ALD/ALE mechanism, precursor design, or process modeling. 
-   Prior work with customer-facing technical validation in a fab or supplier setting. 
-   Detailed knowledge of semiconductor manufacturing processes and materials. 

**What makes this different**

-   A founding-stage role shaping how AI and physics-based models are used in semiconductor materials R&D.   
-   You will see your predictions tested against real process data within weeks, not years. 
-   Freedom to choose methods and tools without legacy constraints.
