Job Description

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.

We are hiring a Chemical/Process Engineer to help accelerate our mission.

About the position

In this role, you will identify and evaluate emerging mineral processing technologies suitable for processing and refining ore produced by KoBold projects. You will consider opportunities and model tradeoffs and process options from ore to final metal product. You will design and implement tests with processing partners to evaluate a wide variety of process steps such as communition, leaching, flotation, hydrometallurgy, pyrometallurgy, direct ion extraction, and in-situ leaching. You will work closely with our metallurgy and commercial teams to identify cost and environmentally optimal methods to process specific KoBold ore compositions.

Ultimately, your role is to help KoBold process the metals needed to enable the energy transition by driving evaluation and partnerships for next generation mineral processing.

Responsibilities

The Chemical/Process Engineer will:

  • Identify and rigorously evaluate emerging mineral processing technologies that are suitable for ore produced by KoBold.
  • Develop technoeconomic models from first principles to compare mineral processing technologies.
  • Collaborate with KoBold's exploration teams, metallurgists, and mine engineers to understand process technology tradeoffs.
  • Model and simulate process flows from mine to product.
  • Help develop KoBold’s proprietary process modeling tools, building a deep understanding of mining and mineral processing sufficient to identify and execute on technology development opportunities.
  • Build partnerships, source, and contract with vendors to develop and customize chemical processing that solves KoBold’s mineral processing needs.
  • Design and evaluate results of lab tests to understand performance implications of bench scale results extended to plant scale.
  • Present to and collaborate with our external partners and stakeholders.
Qualifications

A great Chemical/Process Engineer candidate will have:

  • A successful track record of scaling a chemical process from the bench into production.
  • Excellent communication skills for a highly interdisciplinary workplace.

Technical skills, including extensive experience with:

  • First principle thinking and technoeconomic modeling.
  • Applying scientific knowledge to identify and evaluate emerging technologies.
  • Laboratory analytical and process control methods.
  • Experimental design and analysis.

Training and work experience:

  • Experience as a chemist, chemical or process engineer.

Work practices and motivation:

  • Ability to take ownership and responsibility of large projects
  • 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 chemical or processing experts
  • Excitement about joining a fast-growing early-stage company, comfort with a dynamic work environment, and eagerness to take on a range of responsibilities
  • Ability to independently prioritize multiple tasks effectively

It is also helpful but not required to have experience with:

  • Geochemical and mineralogical data
  • Pyro and hydrometallurgy
  • Modelling in python
  • Kiloton to megaton per year plant design/build/operation
  • Commercial process modeling software such as Aspen HYSYS, HSC, METSIM, JKSimMet/JKSimFloat, etc.
  • Project management

Safe Remote Job Search Tips

Verify Employer Thoroughly

Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.

Never Pay to Get a Job

Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.

Safeguard Your Personal Information

Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.

Scrutinize Communication & Interviews

Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.

Beware of Unrealistic Offers

If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.

Insist on a Formal Contract

Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
