Product Manager, MineOS

About Mariana Minerals

Mariana Minerals is not a software company selling to mining companies. We are a mining company that builds software.

We design, build, commission, and operate our own mines and refineries. We develop our own chemical processes. We're producing battery-grade lithium salts from real oil and gas wastewater in our lab and pilot facilities today. Our first commercial-scale lithium production facility, Lithium One, is targeting production in the first half of 2027.

The software — what we call MarianaOS — exists to make our projects come online faster and run better. We don't sell it. We deploy it into our own operations and measure its impact in tons of metal produced, dollars of cost removed, and months shaved off construction timelines.

Role Overview

We're looking for a Product Manager to own MineOS — Mariana's platform for mining operations from planning through autonomous execution.

MineOS integrates geologic block models, short and long-range mine plans, fleet management systems, and industrial control systems into a single optimization layer. We're accelerating autonomous fleet deployment and working toward global optimal operations across the full mine-to-mill chain. The full scope and complexity of this problem is exceptional. Our goal is to build an accurate digital twin of the site that incorporates the uncertainty inherent in the operations and then use it to determine how to maximize the lifetime value of the mine.

This role spans the full mining value chain: from the geologists who model the orebody, to the engineers who plan extraction sequences, to the operators who run haul trucks and the mechanics who repair equipment. Mining is the last major industrial sector that hasn't been rebuilt with modern software. The opportunity set isn't a feature gap on an existing product — it's entire workflows and systems that don't exist yet. That's rare. Especially at this scale.

You'll work with people who understand the physics of what they're doing and can tell you exactly where the bottlenecks are. There's no translation layer between you and the domain experts. They're your direct collaborators. They'll push back on your designs with real constraints and tell you when your model is wrong and why.

The Product: MineOS

MineOS is Mariana's platform for mining operations—from planning through autonomous execution. It's the system that turns geologic models into mine plans, coordinates extraction activities, and moves toward fully autonomous operations.

What MineOS does:

• Connects long-range strategic planning to daily operational execution in a single loop

• Integrates data feeds from geologic block models, short and long-range mine plans, and drill/blast/haul/crush/stack operations

• Accelerates autonomous fleet deployment, minimizing human interaction with heavy machinery

• Coordinates decisions (and the information needed to make them) across the full mining value chain to maximize value generation

• Moves toward no-human-in-the-loop operations for routine mining tasks

Mining is a complex choreography—drilling, blasting, hauling, crushing, stacking—where each step affects the next. MineOS is how we run a mine as a single integrated system, from the orebody model to the autonomous haul truck.

What You'll Do

• Define what to build by looking at operational performance data and talking to geologists, mine planners, and equipment operators — including figuring out what metrics and instrumentation need to exist in the first place

• Spend 30%+ of your time at mine sites — as much as you want. Understand how decisions get made across the mining value chain, where information gaps exist, and where software can change outcomes

• Bridge very different stakeholders: geologists who think in block models and probability distributions, mine planners who think in sequences and constraints, and haul truck operators who know what's actually happening in the pit

• Ship software that works in the field — dusty, remote, connected to heavy machinery. This isn't a staging environment.

• Own the path toward increased autonomy — where can we remove humans from dangerous or repetitive tasks, and what needs to be true before we do?

• Connect historically siloed systems (block models, mine plans, fleet management, processing) into a single coordinated operation — and define what the interfaces between them should look like

What We're Looking For

Must Have

• 4-7 years in product management, with experience in industrial, mining, construction, or heavy industry software

• Intellectual curiosity about physical systems — you want to understand how blast patterns affect fragmentation and why haul cycle times matter, not just treat the domain as a black box

• Ability to communicate across a huge range of technical literacy — from geologists modeling orebody uncertainty to haul truck operators who've never used software on the job

• Experience working on complex systems with multiple integration points

• Demonstrated ability to ship products in technically challenging environments

Nice to Have

• Experience with fleet management, logistics optimization, or autonomous systems

• Familiarity with mine planning software, block modeling, or industrial control systems

• Background in mining engineering, geology, or heavy industry

Why This Role

Mining is one of the most operationally complex industries on earth — and one of the least digitized. Most mines run on disconnected systems, tribal knowledge, and decisions made by feel rather than data. Almost everything here is greenfield. We're not improving an existing product by 10%. We're building systems that didn't exist before.

At Mariana, you don't need to validate product-market fit because we are the market. If you identify a real problem and build a real solution, adoption is a conversation, not a sales cycle. The constraint is building the right thing, not convincing someone to buy it.

This role is for the PM who thinks in systems — who sees a mine as a single integrated operation from the geologic model to the crusher, not a collection of disconnected workflows. You'll connect the pieces that have never been connected: block models to mine plans to fleet management to processing. You'll work toward a digital twin that incorporates real operational uncertainty and uses it to maximize the lifetime value of the mine. Every project generates operational data that makes the software smarter, which makes the next project faster and cheaper. If you want to work on one of the most complex integration and optimization problems in any industry, this is it.

What It's Like to Work Here

Extreme Ownership – We take full responsibility for outcomes and drive relentlessly toward solutions.

Engineer Out, Then Automate – We simplify and optimize before we scale.

Share Your Legos – We collaborate openly, share knowledge freely, and help each other build better solutions.
