Senior Product Manager
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 how minerals are sourced, refined, and optimized by combining deep industrial expertise with software, automation, and data-driven decision-making. Join us as we build the future of responsible mineral sourcing and supply.
Role Overview
We're looking for a Senior Product Manager to help shape the future of MarianaOS.
This role is for a strong PM who's excited about the breadth of what we're building but isn't yet sure which part of the system is the best fit. We'll figure out together through the interview process which area—Capital ProjectOS, PlantOS, or MineOS—is the right match for your background and interests.
You'll work with an unusually diverse set of stakeholders: geologists, metallurgists, chemical engineers, construction managers, plant operators, ML engineers, and software developers. You'll need to build credibility across these disciplines, translate between their different worldviews, and ship software that works in high-stakes production environments.
This is a senior role. We're looking for someone who can operate independently, drive clarity in ambiguous situations, and own outcomes end-to-end.
The Platform: MarianaOS
MarianaOS is the digital nervous system for mineral projects. It spans the full lifecycle—from capital project execution through autonomous operations:
Capital ProjectOS coordinates engineering, procurement, construction, and commissioning for multi-hundred-million-dollar infrastructure projects. It breaks down silos, brings LLMs into engineering workflows, and enables smaller teams to deliver large-scale projects without the cost overruns that plague the industry.
PlantOS is our autonomy platform for fixed-plant mineral processing—lithium refining, SX-EW, flotation, and beyond. It uses reinforcement learning to dynamically optimize recovery, throughput, and efficiency in ways human-controlled facilities cannot.
MineOS covers mining operations from planning through autonomous execution—connecting geologic models to mine plans to drill/blast/haul/crush/stack operations, moving toward no-human-in-the-loop for routine mining tasks.
These aren't separate products—they're an integrated system that treats minerals production as a single coordinated operation.
What You'll Do
Shape product strategy: Work with leadership to define what we build, in what order, across the MarianaOS platform
Go deep on one area: After initial exposure across the platform, own the roadmap for Capital ProjectOS, PlantOS, or MineOS based on your interests and where you can add the most value
Stakeholder management: Build relationships across engineering, operations, and field teams—understand their workflows, translate their needs, and keep them aligned
Cross-functional delivery: Partner with software engineers, ML engineers, and domain experts to ship solutions that work in production
User research: Spend time at project sites, processing facilities, and mines to understand how work actually happens
-
Drive clarity: Break down complex problems, define scope, make tradeoffs explicit, and keep teams focused on what matters
What We're Looking For
Must Have
5-8+ years in product management, with a track record of shipping impactful products
Exceptional communication and stakeholder management skills
Experience leading cross-functional teams through ambiguous, complex projects
Demonstrated ability to go deep on technical domains and build credibility with engineers
Strong prioritization and tradeoff skills—you know when to say no
Comfort with fast-moving environments and willingness to travel to operating sites
Nice to Have
Background in chemical engineering, mining engineering, process engineering, or related technical field
Experience with industrial software, IoT, process control, or autonomous systems
Familiarity with ML-powered products or data-intensive systems
Experience in mining, energy, construction, chemicals, or heavy industry
Track record of digital transformation work in traditional industries
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'll work across a platform that spans capital project execution, mineral processing, and autonomous mining operations. You'll see software running in real facilities, making real decisions, producing real materials. You'll work on problems that matter—the critical minerals supply chain that powers EVs, grid storage, AI infrastructure, and national security.
If you're a strong PM looking for something more substantive than another enterprise SaaS product, we'd love to talk.
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.
Mariana is an Equal Opportunity Employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
