Teams at Achira

Conduct research to develop generative and sampling models for molecular systems, integrating probabilistic inference, deep learning, and reinforcement learning. Design, train, prototype, and benchmark diffusion, autoregressive, flow-based, and latent-variable architectures. Map between simulation and reality, collaborate with chemists and physicists, and work with engineers to deploy scalable research on distributed compute. Contribute end-to-end from ideation to production in a hybrid San Francisco/New York environment.

Develop and evaluate representation-learning architectures for atomistic systems, including equivariant GNNs and geometric transformers; design pre/mid/post-training curricula and RL strategies; prototype, benchmark, and scale research into reusable components; collaborate with physicists, chemists, and engineers to ground models in physical principles and deploy on distributed infrastructure.

Achira seeks a proactive Office Manager to oversee daily operations, manage logistics and vendor relationships, support employee experience, and enhance office culture in a fast-paced startup environment.
