The Opportunity

Our team is seeking a Software Engineer to contribute to the development of computational chemistry tools, and bridge the gap from R&D prototypes to stable, well-test, production-ready implementations.

As we continue to expand our portfolio of capabilities – spanning physics-based simulations, large-scale data and knowledge graphs, machine learning, and massively parallel computing – we require reliable and efficient software to drive it.

We are looking for an experienced engineer who can enhance our team’s work through the creation of clean software and collaboration with a team of computational chemists, physicists, AI experts, and software engineers. This should be founded in a good understanding of the technical challenges and scientific concepts in the drug discovery space, and deep experience building efficient and maintainable implementations of AI- and physics-based simulation software.

Key Responsibilities:

Maintain and extend existing scientific software packages, and drive the full lifecycle of new ones:
- Architect and implement cutting-edge scientific and ML software alongside subject matter experts
- Adopt current practices and ensure stability through testing
Work closely with the Engineering Team to deploy these modules into the SandboxAQ’s simulation platform:
- Manage dependencies, containerize, and integrate software into CI/CD pipelines
- Integrate with the compute and data backends
- Define API endpoints and schemas
- Collaborate with the engineering team to build UI components
Maintain and support production deployments of scientific software packages
Foster a work culture of curiosity and kindness

Essential Skills & Experiences:

Bachelor's degree in a relevant scientific discipline (for example physics, chemistry, biology, or computer science)
At least 5 years professional experience in software development, designing and developing well-maintained software systems and collaborating with domain experts to design solutions that meet their needs
Strong Python proficiency including experience with numeric and performance libraries like Numpy
Experience with ML libraries like PyTorch
Experience with relevant development tools and environments (git, Unix/Linux, cloud-based platforms, containerization)
Experience using LLM tools and coding harnessed to build quickly while producing understandable, secure, maintainable code that’s a strong foundation for long-term development.
Ability to rapidly write good quality code while not letting the perfect become the enemy of the good
Ability to devise, communicate internally and own technical roadmaps, in a self-directed environment
Desire to work in a fast-paced team with diverse professional experiences and viewpoints

Highly Desired Skills & Experience:

Experience developing software for scientific applications
Familiarity with open source scientific and molecular libraries such as OpenMM, RDKit, Scikit-learn
Experience with modern deep learning architectures
Experience with the drug discovery and drug development processes
