Mariana Minerals is a software-first, vertically integrated minerals company building critical minerals supply chains for modern energy, AI, and defense technologies. You will join as Staff Product Manager owning two core domains of CapitalProjectOS (CPOS)—the operating system for designing, planning, and building capital projects.
You own end-to-end product strategy, roadmap, and execution for MarianaEngineer (centralized system for design basis, process, engineering data, and 3D models) and MarianaSuper (real-time command center for construction execution and plan-versus-actual tracking in the field). You are the single accountable owner working alongside PMs who own procurement and planning/knowledge within the same CPOS team.
Key responsibilities include: owning product vision and roadmap for both domains, including agentic tooling such as engineering automation, reality capture, and plan-versus-actual intelligence; serving as primary domain expert translating capital project engineering and construction workflows into software requirements; acting as bridge between project engineers, superintendents, project controls, software engineering, and executives; embedding directly with engineering and field teams to understand actual workflows and anticipate edge cases; writing clear requirements, user stories, acceptance criteria, and business rules; building and testing prototypes rapidly; establishing structured user engagement model (discovery sessions, workflow reviews, sprint reviews, UAT, adoption check-ins); developing rollout plans, training materials, adoption metrics, and feedback loops; defining and tracking success metrics (modeling/design turnaround time, adoption rates, plan-versus-actual accuracy, cycle time, project outcomes); participating in sprint planning, backlog grooming, and retrospectives; creating visibility into what is being built and how it performs; and helping build the PM function at an AI company by establishing processes and developing future PMs.
This is a high-impact role where you'll own something end-to-end with immediate operational impact. The engineering tools you build set the authoritative source of truth for every project; the command center you build is what superintendents use every morning to run the site. You'll help shape what a modern industrial company looks like from the inside out.
REQUIREMENTS:
Must Have:
- 5+ years of experience in capital project engineering (process, mechanical, or EPC design) and/or construction or field execution (superintendent, construction management, project controls)
- Strong understanding of the capital project lifecycle including design basis, engineering deliverables, procurement handoff, construction execution, and commissioning
- Ability to go deep on engineering and construction workflows and earn credibility with domain experts by understanding how the work actually happens
- Strong product judgment: ruthless prioritization, focus on highest-leverage work, resistance to building everything at once
- Ability to translate complex operational workflows into clear requirements, priorities, and product decisions, and to lead cross-functional teams through ambiguous, complex projects with competing stakeholder priorities
- Genuine interest in AI-powered tooling; ability to translate model capabilities into products that engineers and superintendents will trust and adopt; staying current on cutting-edge AI advancements
- Strong communication skills across a wide range of organizational contexts, from field superintendents and engineers to executives
Nice to Have:
- Direct experience with engineering software (P&ID, 3D/plant design, datasheet or equipment-sizing tools) or construction management software (scheduling, QA/QC, reality capture, command-center platforms)
- Experience shipping AI-powered enterprise tools: agentic engineering workflows, document intelligence, or process co-pilots
- Track record of digital transformation in capital-intensive industries (mining, energy, construction, or manufacturing)
- Prior product management experience, or genuine excitement to move into product management from an engineering or construction background
- AI-forward projects outside of work
