From Mariana Minerals's posting. “We” and “our” refer to the employer.
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.
Mariana Minerals is a software-first, vertically integrated minerals company supplying the minerals critical to modern energy, AI, and defense technologies. Our ML systems don't live in a vacuum — they see and act in our plants through sensors and robotic systems, they run as agents inside the tools the business uses every day, and they run on an ML platform that has to serve all of it.
We're hiring a Machine Learning Engineering Manager to lead the MLEs working on everything outside the chemistry and process models: perception and vision, sensor and robotics initiatives, LLM-powered and agentic workflows, and the ML platform and MLOps infrastructure the whole applied AI/ML organization depends on. You'll manage the people, own the technical quality of what ships, and partner with both Technical Product Managers — ML & Robotics, and Data & Analytics Platform — on what gets built and why.
This is a player-coach role with a wide surface area. The problems range from a camera on a conveyor to an agent answering an operator's question to the training and deployment infrastructure underneath both. Your job is to build a team of strong generalists, keep the platform coherent as the use cases multiply, and give the TPMs a counterpart who can say what is technically possible and what it will take.
You spend most of your time on people, priorities, and quality — and enough time in the code and the systems to keep your judgment sharp.
Turn a loosely defined plant problem or internal-tool idea into scoped engineering work with clear success criteria, and align operators, MLEs, software engineers, and product behind it.
You're credible across perception, LLMs, and infrastructure, and you know when a problem needs a specialist.
Give the TPMs and the business honest estimates, visible tradeoffs, and early warning when something is slipping.
Understand the Mariana ML, perception, robotics, and data ecosystem as a whole — and where it sits relative to the current frontier of model capability — so the team's bets stay well-calibrated.
