Junior Software Developer

Department Globus Labs - Materials

About The Department Globus (www.globus.org) is a sustainable, non-profit unit within The University of Chicago delivering solutions to the research community worldwide. Globus develops and provides critical services that support scientific research for governmental, academic, and commercial organizations in a wide range of disciplines including life sciences, physics, and astronomy. We develop and operate commercial-quality, cloud-based software application and platform services used by 10s of thousands of researchers to manage their large–and growing–data management challenges. We have offices located at the NBC Tower in the heart of downtown Chicago and remote employees who work-from-home. Globus, together with Globus Labs, a research group within the University of Chicago, and part of the Data Science and Learning Division at Argonne National Labs, develop and deploy cutting edge technologies to solve new challenges facing the scientific community and enable break-through scientific discoveries.

Job Summary As a member of the Globus Labs research and software development team, this position will help launch and lead day-to-day work for the newly formed effort in AI interpretability applied to scientific discovery. The role sits at the intersection of mechanistic interpretability, scientific foundation models, and open data infrastructure. It offers a rare opportunity to shape a new research direction from the ground up while building software used by thousands of researchers. The researcher will also contribute to projects that use those models to uncover new scientific insight in domains including materials science, chemistry, catalysis, x-ray science, and more.

We’re looking for a highly skilled developer and emerging researcher with experience applying interpretability methods to large language models and scientific models and using these to understand and improve model performance while also extracting key scientific insights from the models. This work also supports open science initiatives backed by the NSF, NIST, DOE, and the Genesis Mission, as well as a growing set of frontier laboratory and industry collaborations. This at-will position is wholly or partially funded by contractual grant funding which is renewed under provisions set by the grantor of the contract. Employment will be contingent upon the continued receipt of these grant funds and satisfactory job performance.

Responsibilities

• Under the direction of the Principal Investigator, coordinate the day-to-day activities of the new effort in interpretability for scientific discovery. Help track workstreams, milestones, and deliverables, and raise issues to senior staff when needed.
• Assist in developing the group’s research roadmap and priorities so they align with broader laboratory goals.
• Serve as a primary hands-on contributor to research and engineering across group projects, helping keep technical quality consistent.
• Develop tutorials and onboarding materials, and organize regular group check-ins and technical discussions, so new members ramp up quickly and knowledge is shared.
• Implement and apply mechanistic interpretability techniques to scientific foundation models and AI systems. These include feature discovery, sparse dictionary learning, circuit analysis, probing, and activation steering.
• Help investigate how models trained on scientific data represent physical, chemical, and materials concepts, and assist in evaluating how reliable interpretability methods are in these settings.
• Build and maintain reusable tooling, pipelines, and GPU-accelerated workflows for interpretability experiments.
• Support foundation model training, agentic oversight frameworks, and autonomous laboratory efforts as part of a broader team working on scientific automation.
• Contribute to high-priority laboratory initiatives as assigned, including Globus GPU-accelerated inference, ISAAC and other Genesis programs, Terminal-Bench Science, and new laboratory and industry collaborations.
• Contribute developing, deploying, and managing data infrastructure services, including systems for publishing large datasets in materials science, chemistry, and other domains.
• Help define and document requirements and architecture for secure, scalable, asynchronous data access services.
• Develop, test, document, and maintain software on a cloud-based platform, including REST, command-lin…
