About the company:

KoBold Metals is pioneering Digital Exploration by applying statistical modeling, big data aggregation, and foundational ore-deposit science to materially improve the pace and efficacy of natural resources exploration. We are deploying our Machine Prospector tool to discover new ethical sources of Ni, Cu, Co, and Li critical for the electric vehicle revolution.


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. 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, and Standard Investments; and natural resources companies Equinor, BHP, and Mitsubishi.

About the role

LOCATION REQUIREMENT: Remote in Boston and able to drive

We are looking for an experienced Executive Assistant to primarily provide expert, remote administrative support to our Chief People Officer while also executing Boston-based tasks for our executives in the area, and flexing across other departments as needed. 

The ideal candidate approaches each day with an open mind and a can-do attitude. They solve the problems they face with an unflappable demeanor, organized plans, and sophisticated solutions. We are a quickly growing organization with a global presence. Our days are varied, and our EA function serves as the glue that keeps our leaders whole. The right candidate will be viewed as making things easier and better.

Here are a  handful of things that came up this week that would be great to have this EA work on:

  • Create and manage process documentation – Develop comprehensive guides, manuals, or reference materials by gathering information from multiple stakeholders, organizing content, and ensuring accuracy and completeness.

  • Lead cross-functional projects – Act as the project lead for initiatives requiring collaboration across departments, managing timelines, deliverables, and communication to completion.

  • Conduct confidential analyses and reporting – Compile and analyze sensitive internal data to produce clear, actionable reports for leadership decision-making, ensuring information is accurate, secure, and well-presented.

  • Develop reusable tools and resources – Build reports, templates, and frameworks that not only meet immediate needs but can be leveraged for future use.

  • Coordinate document handling and approvals – Facilitate the preparation, review, and execution of important company documents, including obtaining necessary signatures in a timely manner.

  • Capture and visualize workflows – Participate in process-mapping sessions, take detailed notes, and produce visual representations of workflows or procedures, managing feedback and iterations until finalized.

  • Serve as a trusted liaison – Maintain a high level of discretion when working with sensitive matters, ensuring clear, professional communication between executives, teams, and external partners.

Responsibilities

  • Basic support: calendar, email, travel, and reimbursements
  • Advanced support (will increase over time): serve as proxy in meetings and provide synthesis of content and next steps, identify trends in the employee experience needing to be addressed, and assume ongoing responsibility for bodies of work (e.g., co-lead All-hands administration)
  • Special projects: examples above illustrate the type of things in this category, as they are varied in topic, skills required, location, and more
  • Flexibility: provide admin support elsewhere in the org as needed

Requirements:

  • 5+ years of experience as an executive admin, People Operations person, and/or Chief of Staff at a growing company 
  • Trustworthy without exception
  • Strong project management skills with the ability to work independently and drive initiatives to completion.
  • Exceptional organizational skills and attention to detail.
  • High level of discretion and integrity when handling sensitive or confidential information
  • Proficiency with productivity tools (Google Workspace, Microsoft Office) and diagramming software (Lucidchart, Miro, or similar).
  • Ability to work effectively in a fast-paced, dynamic environment.
  • Great at using spreadsheets or similar apps to create reports and build tools
  • Flexible 
  • Proven ability to anticipate issues and solve them before they manifest by thinking ahead
