While this role is level-agnostic, it is best suited for engineers with experience owning and working in highly ambiguous problem spaces.</p>\n<p>About the company:\nThe mining industry has steadily become worse at finding new ore deposits, requiring &gt;10X more capital to make discoveries compared to 30 years ago. KoBold Metals builds AI models for mineral exploration and deploys those models,alongside our novel sensors,to guide decisions on KoBold-owned-and-operated exploration programs.</p>\n<p>About The Role:\nIn this role, you will partner with exploration and engineering teams to build reliable, scalable infrastructure that makes it easier to turn data and models into real-world exploration insights. You will improve observability, streamline MLOps workflows, and maintain shared tools like JupyterHub that enable faster experimentation and collaboration. Your work will help create a solid foundation for scientists and engineers to focus on discovery instead of infrastructure.</p>\n<p>Responsibilities</p>\n<ul>\n<li>Design, build, and operate compute infrastructure that is both scalable and reliable to support critical services.</li>\n<li>Work closely with engineering teams to embed observability, reliability, and security throughout the software development process.</li>\n<li>Create and maintain automation for monitoring, deployments, and incident response to keep operations efficient and predictable.</li>\n<li>Lead or support capacity planning, performance reviews, and system tuning to ensure stable and efficient systems.</li>\n<li>Join the on-call rotation and take part in incident response, troubleshooting, and resolution.</li>\n<li>Develop and refine monitoring and alerting to catch issues early and reduce downtime.</li>\n<li>Establish and maintain disaster recovery and business continuity practices that protect the organization against failures.</li>\n<li>Regularly review and improve our tools and processes to strengthen system visibility and reliability.</li>\n<li>Investigate points of fragility in distributed systems and understand how complex systems behave under stress in order to improve resilience.</li>\n<li>Continually learn about mineral exploration through reading, discussions with exploration team members, periodic rotation on an exploration team and time in the field with geologists</li>\n</ul>\n<p>Qualifications</p>\n<ul>\n<li>5+ years of experience as an Infrastructure Engineer, Site Reliability Engineer or in a similar role</li>\n<li>Strong scripting and programming skills (Python, Go, Java or JavaScript/ Node.js )</li>\n<li>Experience with IaC tools like Terraform and container orchestration tools like Kubernetes and Docker</li>\n<li>Experience with cloud platforms such as AWS</li>\n<li>Experience operating or administering JupyterHub in a multi-user environment</li>\n<li>Understanding of MLOps workflows, including model training, deployment, and related tooling</li>\n<li>Excellent communication &amp; collaboration skills and a continuous improvement mindset</li>\n<li>Proven ability to troubleshoot complex issues and implement effective solutions</li>\n<li>Proven ability to thrive in dynamic and evolving environments, effectively navigating uncertainty and incomplete information.</li>\n<li>Proven ability to grow expertise, influence &amp; educate others</li>\n<li>Comfortable making informed decisions with limited data, adapting quickly to new circumstances, and maintaining focus on strategic objectives while driving clarity for the team.</li>\n<li>Intellectual curiosity and eagerness to learn about all aspects of mineral exploration, particularly in the geology domain.
