What are Contract Mining Engineers?

Contract Mining Engineers are professionals who are hired on a temporary or project basis to provide engineering expertise in the planning, development, and operation of mines. Their responsibilities may include designing mining methods, ensuring safety compliance, optimizing production processes, and solving technical problems on-site. Unlike permanent staff, contract mining engineers typically work for a specific duration or for the length of a particular project, offering flexibility for both employers and engineers. This role often requires strong analytical skills, practical mining experience, and adaptability to different mining environments. Contract mining engineers may work with mining companies, consulting firms, or as independent contractors.

What are the key skills and qualifications needed to thrive as a Contract Mining Engineer, and why are they important?

To thrive as a Contract Mining Engineer, you need a degree in mining engineering or a related field, solid knowledge of mining methods, and strong analytical skills. Familiarity with mining software such as Surpac, Vulcan, or MineSight, and certifications like a Professional Engineer (PE) license, are often required. Excellent problem-solving, project management, and communication skills help you excel in dynamic, project-based environments. These competencies are crucial for ensuring safe, efficient, and cost-effective mining operations while meeting project deadlines and client expectations.

How does a Contract Mining Engineer typically collaborate with site management and other contractors on a project?

As a Contract Mining Engineer, collaboration is key to ensuring project success. You'll regularly coordinate with site management to align engineering plans with operational goals, address safety standards, and respond to any on-site issues. Additionally, you'll work closely with other contractors and subcontractors, ensuring clear communication about timelines, resources, and technical requirements. This teamwork is essential to optimizing mine productivity and minimizing costly delays, so strong interpersonal and project management skills are highly valued in this role.

What is the difference between Contract Mining Engineer vs Mining Engineer?

AspectContract Mining EngineerMining Engineer
CredentialsEngineering degree, relevant certifications, often with contract-specific agreementsEngineering degree, professional licensure, often permanent employment
Work EnvironmentProject-based sites, temporary contracts, variable locationsCompany sites, permanent positions, consistent locations
Employer & Industry UsageMining contractors, consulting firms, project-based companiesMining companies, resource firms, permanent staff roles

Contract Mining Engineers typically work on a temporary basis at specific sites, focusing on project delivery, while Mining Engineers are usually employed full-time by mining companies, overseeing ongoing operations. Both roles require similar technical skills and certifications but differ mainly in employment type and work setting.

Job description

About Mariana Minerals
Mariana Minerals is a software-first, vertically integrated minerals company on a mission to supply the critical minerals powering modern energy, AI, and defense technologies. We're reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.
The Role
Mariana Minerals is building the critical minerals supply chain from the ground up-and we're looking for a Senior Data Engineer to help make it autonomous.
We're not a software company selling tools to mining operators. We are a mining company that builds software. Mariana designs, builds, commissions, and operates our own mines and refineries. We develop proprietary chemical processes and run them at lab, pilot, and commercial scale. Today, we're producing battery-grade lithium salts from real oil and gas wastewater in our facilities. Our first commercial-scale lithium production facility, Lithium One, is targeting initial production in Q1 of 2027.
As a Senior Data Engineer at Mariana, you'll own a data domain end-to-end-designing the pipelines, schemas, and contracts that make a whole class of plant data trustworthy and queryable. The systems you build are the foundation every model and every operational decision depends on.
The Tech
This is some of the most interesting applied data work happening today.
Our internal platform, PlantOS, uses the same reinforcement learning toolkits that power self-driving vehicles and humanoid robots-but applied to autonomous, short-interval control of mineral refining circuits. None of it works without data: every set point those models adjust, and every decision we make about a plant, rests on turning messy industrial reality into trustworthy, queryable, model-ready data.
The environment is noisy and non-stationary: sensors drift, lab results arrive late and malformed, wastewater compositions shift, equipment ages. The data backbone has to keep up. The end goal is fully autonomous refining operations-and the pipelines you build are the foundation everything else stands on.
What You'll Do
  • Work across domains-for example, all plant sensor and historian data, or all lab and analytical results-including schema design, orchestration, reliability, and the contract it exposes to everyone downstream.
  • Design and evolve our fleet of pipelines that pull from messy industrial sources-sensors, lab systems, historians, imagery, and more-into our databases and warehouse.
  • Model time-series and analytical plant data for both human analysis and machine learning training, validation, and monitoring; own data quality, observability, and lineage in your domain.
  • Build the data architecture that feeds production ML-the training and monitoring layer-in partnership with the ML engineers who own the model-specific semantics.
  • Mentor earlier-career engineers and define the data contracts other teams build against.
  • Work the boundary with machine learning deliberately: you own the platform and the interface it exposes; ML engineers own the features and models built on top of it. The training and monitoring layer is shared ground you design together.
Desired Qualifications
  • 4+ years in data engineering or a closely related role.
  • Strong Python and SQL, with deep experience designing database and warehouse schemas, including time-series and/or analytical data.
  • Proven experience building reliable, orchestrated data pipelines and operating them in the cloud with containers and CI/CD.
  • Experience with data quality, observability, and lineage, and comfort with messy real-world sources-drifting sensors, malformed exports, and the quirks of industrial systems.
  • A self-starter comfortable in high-ambiguity environments, working directly with process engineers, ML engineers, and operations teams.
  • Bonus: experience feeding data to ML systems-training datasets, feature pipelines, model monitoring-or working with industrial, sensor, or historian data.
Why This Role
We own the projects, generate the data, and close the loop. Every facility we build makes the software smarter-and the next facility faster and cheaper.
Mining is one of the last major industrial sectors that hasn't been rebuilt with modern software. The opportunity here isn't a feature gap-it's entire workflows and systems that don't exist yet.
Your work will directly shape how critical minerals are produced at scale in the coming decades.
Our culture is built on three principles:
Extreme Ownership - We take full responsibility for outcomes, relentlessly driving toward solutions.
Engineer Out Requirements, then Automate - We simplify, optimize, and then automate for scale.
Share Your Legos - We collaborate openly, share knowledge, and empower each other to build bigger, better solutions.
Join us as we build the future of responsible mineral sourcing and supply.
