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
We’re hiring a Staff Product Manager to own a critical domain within MarianaOS. This is a single posting because we recruit for the strongest PMs first and then place them where the fit is best. Through the interview process, we’ll figure out together which part of the system is the right match for your background and instincts.
The scope of what we can touch is enormous. 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. The problem space spans micron-scale chemistry to kilometer-scale infrastructure.
Ship a feature and you can watch the needle move — recovery rates, reagent consumption, construction timelines, equipment uptime. These aren’t proxy metrics. They’re the actual physics of making metal. This role is On-site and will require significant travel.
THE PLATFORM: MARIANAOS
MarianaOS is the digital nervous system for mineral projects. It spans the full lifecycle — from capital project execution through autonomous operations. The three domains make are staffing for right now are:
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 building an accurate digital twin of the site to maximize the lifetime value of the mine.
Our autonomy platform for fixed-plant mineral processing — lithium refining, SX-EW, flotation, and beyond. It uses the same reinforcement learning toolkit powering self-driving vehicles and humanoid robots, except we’re using it for autonomous control of minerals refining circuits.
The operating system for running the business — connecting fragmented tools, eliminating manual handoffs, and giving leadership real-time visibility into project economics and operational performance across the entire portfolio.
WHAT YOU’LL DO
WHO THRIVES HERE
We’ve seen two profiles excel in this kind of environment. You likely see yourself in one of these:
You’ve shipped products where hardware and software meet and where software failure has physical consequences. You think in fleet coordination, sensor fusion, and operational reliability. You may have started as an engineer and moved into product because you wanted to own the outcome, not just the component.
You’ve worked with ML and AI in production — reinforcement learning, process control, optimization. You know how to bridge the gap between what a model can do and what an operator will actually trust. You’ve translated research into shipped products in high-stakes environments.
We’re also drawn to people with strong PM fundamentals who’ve operated in complex, high-ambiguity environments — or people from industrial backgrounds (manufacturing, energy, construction, logistics) who have genuine product instincts even if “PM” has never been in your title.

WHY THIS ROLE
Most senior PM roles are narrowly scoped — you own one product, one feature set, one customer segment. This role is different.
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.
The number and diversity of problems is unusual: you might work across agentic LLM systems for engineering workflows, RL-based process control, and autonomous fleet optimization in the same quarter.
This is not SaaS. This is software that runs mines and refineries. If you’re a strong PM looking for something more substantive than another enterprise software product, we’d love to talk.
WHY JOIN US?
At Mariana Minerals, you’ll be part of a mission-driven team reshaping the way critical minerals are sourced and supplied globally. You’ll have the autonomy to make big decisions, the tools to innovate, and a culture that values ownership, smart automation, and collaboration.
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.
Mariana is an Equal Opportunity Employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. We do not discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, or any other protected status.
