Staff ML Engineer

KoBold Metals is a mineral exploration company using AI to explore for the metals we need for our transition to a low-carbon economy. KoBold’s business is discovering defining expanding and developing mineral resources and KoBold’s objective is to achieve a step-change improvement in exploration success: we aim to discover more tier 1 resources faster and with fewer failures.

KoBold has a global portfolio of more than 50 exploration properties targeting nickel copper cobalt and lithium which range from 100%-owned to partnerships with both majors junior explorers and prospectors.

Our team includes the best of the industry in exploration geoscience data science software engineering operations and business personnel. Prior to joining KoBold KoBold team members have made nearly 20 discoveries. Our exploration programs are co-led by our geoscientists and data scientists who develop exploration hypotheses rigorously quantify uncertainty in our understanding of the subsurface and design data collection programs that most effectively reduce uncertainty drawing upon a large suite of proprietary exploration technology built by our data scientists and software engineers. Our field programs validate and improve the system and have demonstrated material improvements over conventional exploration methods

KoBold is privately held and our investors include: institutional asset managers T. Rowe Rice and Canada Pension Plan Investments; technology venture capitalists Andreessen Horowitz Bill Gates’s Breakthrough Energy Ventures BOND Capital Standard Investments and Sam Altman’s Apollo Projects; and leading natural resources companies Equinor Mitsubishi and BHP.

About the position:

At KoBold we believe that a modern ML stack will enable systematic mineral exploration and materially improve the success rate. This role is a key ingredient to this strategy. As a member of our software engineering team you will apply software engineering and machine learning to large remote-sensing datasets in order to build scalable ML systems to help make high-speed high-quality decisions for our mineral exploration projects. Collaborating with our exceptional team of data scientists and geologists you will tackle complex scientific problems head-on and collectively pave the way for discoveries of vital energy transition metals like lithium copper nickel and cobalt. Together we can shape the future of mineral exploration and contribute to building a sustainable world.

Responsibilities of this role include:

• Architect implement and maintain foundational scientific computing libraries that will be used in Kobold’s mineral exploration analyses.

• In collaboration with other engineers build ML tooling to increase the velocity of our machine learning progress including enabling rapid prototyping in Jupyter notebooks; building experimentation evaluation and simulation frameworks; turning successful R&D into robust scalable ML pipelines; and organizing models and their outputs for repeatability and discoverability.

• In collaboration with data scientists build models to make statistically valid predictions about the locations of compositional anomalies within the Earth’s crust.

• Apply–and coach team members to use–engineering best practices such as writing testable and composable code

• Collaborate with data scientists geoscientists and engineers to invent the modern scientific computing stack for mineral exploration

Qualifications

Our ideal candidate will have:

• At least 5 years of experience as a software engineer data scientist or ML engineer though most great candidates will have closer to 10. Recent bachelor’s/master’s candidates are unlikely to be competitive.

• Track record of building production ML solutions or tooling that have delivered business value

• Proficiency with foundational concepts of ML

• Proficiency in Python ideally including array-based packages such as xarray and numpy

• Proficiency in a variety of parallel computing patterns for example using distributed computing frameworks such as Dask

• Flexibility to engage with data scientists and increase their productivity for both experimental and production workflows

• An open-mind and curious attitude to learn and embrace the unique challenges of applying machine learning to mineral exploration such as limited groundtruth data complex quality metric design and difficulties to create generalizable models

• Collaborative attitude to work with stakeholders with different backgrounds (data scientists geoscientists software engineers operations)

Work practices and motivation:

• Ability to take ownership and responsibility of large projects.

• Intellectual curiosity and eagerness to learn about all aspects of mineral exploration particularly in the geology domain. Open to working directly with geologists in the field. Enjoys constantly learning such that you are driving insights and innovations.

• Ability to explain technical problems to and collaborate on solutions with domain experts who aren’t software developers. A strong communicator who enjoys working with colleagues across the company.

• Excitement about joining a fast-growing early-stage company comfort with a dynamic work environment and eagerness to take on a range of responsibilities.

• Keen not just to build cool technology but to figure out what technical product to build to best achieve the business objectives of the company.

• Ability to independently prioritize multiple tasks effectively.
