About the Company
We are an early-stage scientific software company building a computational platform for modeling chemical reactivity in complex molecular systems. Our platform combines quantum chemistry, machine learning, and molecular simulation to help scientists understand and predict molecular behavior where reactivity, dynamics, and structure determine performance. Initial applications include therapeutics, radiopharmaceuticals, catalysis, and related chemistry-intensive fields.
We are looking for an early technical hire who can help turn advanced molecular simulation methods into reliable, deployable workflows for real scientific and commercial problems.
The Role
As a Computational Chemistry / Molecular Simulation Engineer, you will build and deploy ML/QM simulation workflows for modeling chemical reactivity. You will work across molecular dynamics, quantum chemistry, machine-learned interatomic potentials, scientific software engineering, and external scientific partner projects.
This role is well suited to a recent PhD, postdoctoral researcher, or equivalent technical contributor who wants to move quickly in an early-stage startup environment. You should be comfortable with ambiguity, independent execution, and building useful systems rather than only running isolated research calculations.
What You Will Do
You will:
- Build data pipelines for DFT, QM/MM, and molecular simulation training data.
- Fine-tune MACE or related machine-learned interatomic potential models.
- Run validation against reference QM, DFT, and QM/MM data.
- Develop reproducible molecular simulation workflows for reactive chemistry problems.
- Package computational workflows for external scientific partner projects.
- Integrate simulation pipelines with cloud and HPC infrastructure.
- Translate scientific problems into reliable computational workflows.
- Write clear documentation and maintain production-quality scientific code.
