Develop targeted searches, engage passive candidates, conduct talent mapping and market research, partner with engineering leaders, track sourcing metrics, improve recruiting processes, build diverse pipelines, and strengthen the employer brand and candidate experience.

Develop sourcing strategies for highly technical roles, identify and engage passive candidates, conduct talent mapping and market research, partner with engineering leaders, build specialized candidate pipelines, track sourcing metrics, improve recruiting processes, and strengthen the employer brand and candidate experience.

Designs and executes hydrometallurgical experiments at laboratory and pilot scale. Operates reactors, filtration, separation, and purification equipment; monitors process parameters; prepares reagents; collects and analyzes data; and optimizes extraction through DOE and statistical methods. The role also produces reports and visualizations, maintains laboratory documentation, troubleshoots and calibrates equipment, conducts hazard assessments, and follows chemical safety, PPE, MSHA, and OSHA protocols.

Leads instrumentation and controls engineering for mineral refining equipment and plant-wide systems from concept through commissioning and operations handover. Manages equipment providers, licensors, engineering firms, procurement, installation, calibration, inspections, QA/QC, startup, and troubleshooting. Drives scale-up of novel refining processes, supports machine learning and advanced control development, mentors junior engineers, and contributes to capital project execution and engineering team growth.

Lead controls and instrumentation engineering for novel mineral refining facilities from concept through commissioning, ramp, and handover. Manage equipment providers, licensors, engineering firms, and cross-functional technical teams. Oversee instrument, valve, analyzer, network, and control-system selection and installation; support industrial machine-learning optimization and workflow automation. Mentor junior engineers and contribute to medium-to-large capital project execution, plant-network security, and development of the internal engineering team.

Support the design, fabrication, installation, commissioning, maintenance, and troubleshooting of pilot plant equipment and refining systems. Translate process requirements into mechanical designs and equipment modifications, maintain engineering documentation, improve reliability and maintainability, and collaborate with process engineers and R&D scientists. Travel to company sites for project support, startup, commissioning, and troubleshooting.

Build and deploy full-stack software supporting engineering, construction, and operation of mineral processing facilities. Develop Autodesk integrations, internal web applications, software ecosystem evaluations, and LLM-powered experiences. Collaborate with ML engineers on data architecture and pipelines supporting model training and facility operations visibility. Partner directly with engineering, construction, operations, and other non-software stakeholders to identify needs, scope features, and drive implementation across the technology stack.

Owns systems administration, infrastructure implementation, networking, identity, device management, licensing, backup and disaster recovery across corporate, field, and industrial sites. The role builds IT processes, security controls, incident response, change management, help desk operations, and hardware lifecycle programs. It also coordinates managed service providers, supports complex user and site issues, mentors junior staff, and collaborates with engineering, HR, and on-site stakeholders. Approximately 25% travel is required.

Develop autonomy software for mining vehicles, including perception, SLAM, motion planning, control, sensor fusion, localization, and mapping. Integrate LiDAR, cameras, radar, IMU, and GNSS while building embedded real-time systems. Create simulation, logging, and data pipelines, and validate autonomy software through bench, rig, and field testing. Collaborate with hardware, controls, and systems engineers to deliver safe, reliable vehicle autonomy.

Lead Mariana Minerals’ creative execution and visual identity. Responsibilities include owning brand architecture, evolving visual identity, designing digital and physical materials, creating campaign and website assets, developing design systems, directing photography and video, maintaining brand guidelines, organizing asset libraries, establishing workflows, and managing external creative contractors.

Own end-to-end procurement of capital process equipment, including sourcing strategy, contract negotiation, supplier competition, purchase order conversion, change orders, and commercial risk management. Analyze spend to identify savings, improve procurement workflows, and build scalable, audit-ready systems supporting capital project schedules and efficiency.

Own end-to-end pre-operational procurement for new projects and sites: define specs with engineering, run RFQs, qualify vendors, negotiate contracts, execute purchases, manage first deliveries, consolidate sourcing for volume savings, and transition vendor relationships to on-site procurement.

Lead the planning and design for greenfield mining projects, including site selection, feasibility studies, and civil works design. Collaborate with multiple teams for optimal site infrastructure design and manage external engineering partners.

The Project Engineering Manager leads engineering teams, manages project workflows, coordinates reviews, and ensures timely deliverables for critical minerals supply chain projects.

Design, prototype, and validate electromechanical and robotic hardware for autonomous mining vehicles, including drive-by-wire actuation, motion and powertrain systems, manipulators, and end-effectors. Produce CAD, BOMs, select components, lead bench and field testing, and collaborate with controls and autonomy teams to integrate hardware, sensing, and compute for fully autonomous operation.

Design, implement, and validate autonomy software for mining vehicles including perception, localization, mapping, motion planning, and control. Integrate and calibrate LiDAR, camera, radar, IMU/GNSS sensors; build embedded real-time software; develop simulation and data pipelines; and lead bench, rig, and field validation while collaborating with hardware and controls teams.

Lead end-to-end execution of Mariana's capital project programs from development through construction, owning schedules, budgets, risk management, and cross-functional coordination. Manage and grow a team of Technical Program Managers, drive deployment of capital-project software tools, standardize project development and execution, and partner with finance and business development on capital allocation and project economics.

The Staff Product Manager will own a product domain at Mariana Minerals, focusing on software development for physical systems in mining and minerals processing, requires significant on-site experience and cross-functional leadership.

The Senior Full Stack Software Engineer will lead software architecture and implementation, mentor team members, and integrate complex systems for minerals supply chain management.
