Senior Drilling Engineer

Senior Drilling Engineer About the Company The mining industry has steadily become worse at finding new ore deposits, requiring >10X more capital to make discoveries compared to 30 years ago. The easy-to-find, near-surface deposits have largely been found, and the industry has chronically under-invested in new exploration technology, relying on the manual techniques of yesteryear — even as demand accelerates for copper, lithium, and other metals to build electric vehicles, renewable energy, and data centers. KoBold builds AI models for mineral exploration and deploys those models — alongside our novel sensors — to guide decisions on KoBold-owned-and-operated exploration programs. Since our founding in 2018, KoBold has become by far both the largest independent mineral exploration company and the largest exploration technology developer. Our data scientists and software engineers, who come from leading technology companies, jointly lead exploration programs with our renowned exploration geologists. KoBold has proven its first discovery with materially less capital than the industry average and found one of the best copper deposits ever discovered: the copper is far more concentrated than the global average of copper mines, and this asset alone is expected to generate meaningful revenue for decades. KoBold has a portfolio of more than 60 other projects, each of which has the potential for another high-quality discovery. KoBold is privately held; investors include institutional asset managers T.

Rowe Price and Canada Pension Plan Investments; technology venture capitalists Andreessen Horowitz, Breakthrough Energy Ventures, BOND Capital, Durable Capital, StepStone, and Standard Investments; and natural resources companies Equinor, BHP, and Mitsubishi. About the Role: In the role of Senior Drilling Engineer, you will design, plan, and provide technical oversight of drilling programs across KoBold’s global exploration portfolio. You will work closely with our science teams to translate exploration objectives into hole designs, drilling programs, and operational plans that deliver safe, high-quality data collection at optimal cost. You will report to the Vice President Field Operations and collaborate daily with Geologists, Data Scientists, Field Operations, Drilling, HSE, and other functions. Your primary responsibility will be to serve as the technical lead for drilling engineering on multiple concurrent projects across diverse geographies and commodities. Responsibilities Design and Plan - Lead hole design, drilling method selection, and rig specification for complex exploration drilling programs including diamond core, sonic, reverse circulation and air core programs - Develop comprehensive drilling execution plans: scope, cost estimates, schedules, risk assessments, and procurement strategies - Complete detailed engineering design to inform the development of drilling programs for various hole types including casing design, torque and drag analysis, directional drilling design, mud system design. - Complete detailed root cause analysis on all downhole failures with a particular focus on rod string and thread failures, stuck in hole, wireline failures and the correlation to dogleg severity, hole trajectory, and adherence to good drilling practices.
