Company Overview

KoBold Metals

Berkeley, California, United States

2018

Approximately 90 employees (source: research.contrary.com). No public revenue figures available for 2023 or later.

What They Do

KoBold Metals specializes in AI-driven mineral exploration, focusing on sourcing critical battery metals such as copper, lithium, cobalt, and nickel. Unlike companies that generate renewable energy directly, KoBold's mission is to support the electrification movement by ensuring a steady supply of essential minerals needed for energy storage solutions (source: cbinsights.com). The company employs advanced technologies, integrating geosciences with machine learning, historical drilling data, satellite imagery, and geological surveys to create predictive models that function similarly to a "Google Maps" for underground mineral deposits (source: carboncredits.com). With a portfolio of 40 patents primarily in drilling technology and petroleum production, KoBold is positioned at the forefront of mineral exploration innovation (source: cbinsights.com). The company generates revenue by securing land claims, owning stakes in discovered resources, and forming joint ventures with mine operators, targeting battery producers as indirect customers (source: research.contrary.com).

Projects & Track Record

As of December 2022, KoBold Metals has established positions in over 30 projects across three continents, beginning with cobalt prospecting in northern Quebec, near Glencore's Raglan nickel mine, and expanding into lithium detection in the same region (source: research.contrary.com). A significant ongoing project is the Mingomba Deposit in Zambia, which is a $150 million joint venture announced in December 2022 with EMR Capital and ZCCM-IH, targeting one of the largest copper discoveries in over a decade, as revealed in July 2024 (source: carboncredits.com). Other notable efforts include a joint venture with BHP covering 500,000 square kilometers in Western Australia, and ground-breaking activities at Disko Island in Greenland for cobalt and nickel in collaboration with Bluejay Mining (source: research.contrary.com). The company is also exploring opportunities in Saskatchewan, Ontario, Quebec, and has plans for U.S. lithium projects, showcasing its broad geographic presence and strategic partnerships (source: carboncredits.com).

Recent Developments

In June 2023, KoBold Metals successfully raised $195 million at a valuation of $1.15 billion, marking a significant milestone in its funding journey (source: investclub.sv). The company secured an additional $491 million toward a $527 million funding round as of a recent regulatory filing, achieving unicorn status with a valuation exceeding $1 billion and targeting $2 billion, backed by prominent investors such as Andreessen Horowitz and T. Rowe Price (source: carboncredits.com). The latest funding round of $491 million occurred on October 4, 2024, further solidifying its financial foundation (source: golden.com). Additionally, in July 2024, the company announced the discovery of the massive Mingomba copper deposit in Zambia, utilizing its AI capabilities to enhance exploration efficiency (source: carboncredits.com).

Working There

KoBold Metals offers a range of roles primarily focused on geoscience, AI and data science, exploration operations, and business development, reflecting its commitment to mineral prospecting and joint ventures (source: research.contrary.com). The company employs approximately 90 individuals, with its careers page indicating potential openings at its Berkeley headquarters (source: linkedin.com). The culture at KoBold is characterized by a high-leverage, tech-driven environment that aims to tackle climate challenges through electrification, drawing on the diverse experiences of its team members who have backgrounds in academia, investing, and hard sciences (source: research.contrary.com). While specific benefits are not publicly documented, the innovative and collaborative atmosphere suggests a focus on fostering creativity and problem-solving in the energy-technology intersection.

Job Description

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. In the six years since founding, 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.

We are hiring Software Engineers to accelerate our mission.

About The Role

At KoBold, software engineers have the unique opportunity to embed directly with their users and learn the ins and outs of mineral exploration and geology while developing state of the art technology solutions. Unlike traditional software engineering roles, we don't simply ship code and passively wait for feedback about its utility: our userbase includes our colleagues... and ourselves! While there are real technical challenges in making mineral exploration data broadly searchable and accessible to both humans and machines, we believe that solving these technical challenges cannot be done without "getting our hands dirty" - sometimes literally! - by embedding directly with the exploration teams and even occasionally (~once a year) joining our colleagues in the field, be it in Zambia, Canada, or Arizona, to experience the impact of our software in real time.

As a Software Engineer on the Data Systems Engineering team at KoBold, your main role will be to enable systematic exploration and materially improve exploration success rates by making mineral exploration data broadly accessible to humans and machines. Past projects have included SIP (the Structured Ingest Pipeline), DataKit generation (producing curated sets of data on demand), and RAG (Retrieval Augmentation Generation, utilizing natural language processing on unstructured data). Our tech stack is primarily python and includes Django, React, AWS, and additional technologies like Retool and Prefect.

Your work will empower KoBold to unlock invaluable insights and streamline intricate scientific processes. Collaborating with our exceptional team of data scientists, geologists, and other software engineers, you will have the opportunity to tackle complex problems head-on and collectively pave the way for the 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.

This role be responsible for:

  • Deep engagement with exploration geologists and data scientists, continual learning about mineral exploration, and tailoring technology development to the needs of exploration project scientists
  • Building data pipelines and tooling for deriving advanced human and machine insights from exploration data, often leading a small group of software engineers to successful delivery
  • Developing expertise in KoBold's Data Systems and deeply understanding how they impact exploration
  • End-to-end ownership of projects from design to implementation and testing to continued engagement with colleagues on exploration teams using your solutions
  • Responding well to design and code feedback, also providing feedback to teammates
  • Operationally managing the team's services and assisting scientific colleagues with our tooling

Qualifications

  • 4+ years of software engineering experience, ideally building production cloud data systems
  • Proficiency with Python
  • Ability to write production-quality code that is correct, readable, well-tested, scalable and extensible
  • Skilled in large-scale system design
  • A track record of taking ownership from definition of the problem and delivering projects with demonstrated impact in an iterative manner
  • Intellectual curiosity and eagerness to learn about all aspects of mineral exploration, particularly in the geology domain. Enjoys constantly learning such that you are driving insights through using our tools in exploration and willing to work directly with geologists in the field.
  • Ability to explain technical problems to and collaborate on solutions with domain experts who are not 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 an evolving 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.

Nice to Haves

  • Experience with modern frontend frameworks such as React
  • Experience with geospatial data and building map-based experiences
  • Familiarity with containerization and container orchestration platforms, such as Docker, AWS ECS, Kubernetes, etc.
  • Formal education or job exposure to natural sciences
