SWE - Backend

Why Achira

Join a world-class team of scientists, ML researchers, and engineers working together to reshape the future of drug discovery.

Work on cutting edge ML infrastructure at frontier scale : massive compute, massive data, and massive ambition.

Own impactful work end-to-end — from ideation to architecture to deployment on large-scale infrastructure.

Work in an environment that rewards rigor, speed, and a builder’s mindset.

About the Role

Achira is building best-in-class foundation models to solve the most challenging problems in simulation for drug discovery and beyond. Atomistic Foundation simulation models (FSMs) as world models of the physical microcosm span machine learning interaction potentials (MLIPs), neural network potentials (NNPs), and diverse classes of generative models.

We are seeking an experienced and passionate Backend Software Engineer to join our growing team. You will be instrumental in designing, building, and maintaining the scalable backend systems that power our ML infrastructure. This role demands a high degree of ownership, a deep understanding of software design principles, and a commitment to building robust, maintainable, and high-performance services. You will play a key role in shaping our technical roadmap and driving technical excellence within a fast-paced, collaborative environment.
