Mariana Minerals is a software-first, vertically integrated minerals company focused on supplying critical minerals for modern energy, AI, and defense technologies. The company combines deep industry expertise with advanced software, automation, and data-driven decision-making to reimagine the minerals supply chain.
As Senior Safety Engineer, you will lead ISO 45001 implementation and help solve safety challenges in equipment and facility design. You will establish the management system at an initial site, build company policies and procedures for adoption across other locations, and support integration as Mariana develops new operations.
Key responsibilities include:
- Leading ISO 45001 gap assessments and implementation plans with clear priorities, owners, milestones, and completion evidence
- Developing practical OHS policies and procedures, involving workers and building consistent systems for future sites
- Coordinating internal audits, compliance evaluations, management reviews, corrective actions, and certification readiness
- Supporting new locations through design, construction, commissioning, and operations, adapting the framework to local hazards
- Leading or supporting equipment risk assessments and design reviews for fixed/mobile equipment, safeguarding, interlocks, and emergency stops
- Defining safety functions and requirements; performing and reviewing performance level or safety integrity level calculations
- Developing and executing verification and validation activities with full traceability
- Providing engineering input on facility, fire, and life safety questions with qualified design specialists
- Supporting incident investigations, field risk assessments, training, and H&S improvements with site teams
- Contributing to design and commissioning reviews, hazardous energy isolation, and practical improvements
The expected focus is approximately 50% ISO 45001 and OHS management systems, 30% functional safety engineering, and 20% general safety engineering support. You will spend time with operational teams and translate technical requirements into practical solutions.
QUALIFICATIONS:
- Typically 7+ years of relevant safety engineering, industrial engineering, or OHS experience, including substantial responsibility for ISO 45001 implementation in an industrial setting
- Approximately 3–5 years of hands-on functional safety or safety-related control-system experience, including risk assessments, safety requirements, calculations, and testing
- Applied knowledge of ISO 45001 and familiarity with other OHS management systems such as ANSI/ASSP Z10 or ILO-OSH 2001, plus relevant audit and implementation guidance
- Experience applying machinery risk assessment and functional safety methods, including ISO 12100 and ISO 13849 or IEC 62061; ability to read engineering drawings and control narratives and explain safety calculations
- Strong technical writing, facilitation, and project delivery skills; ability to work through design disagreements and coach teams
- Sound judgment about applicable safety requirements and limits of expertise, with ability to engage specialists and maintain momentum
PREFERRED QUALIFICATIONS:
- Bachelor's degree in mechanical, electrical, mechatronics, controls, systems, industrial, safety, or closely related engineering discipline; equivalent demonstrated engineering experience considered
- Experience taking a site through ISO 45001 certification, recognized lead-auditor training, or deployment of systems across multiple locations
- Experience in mining, mineral processing, chemicals, manufacturing, or comparable operations; familiarity with SISTEMA, safety PLCs, or automated equipment; relevant functional safety training or CSP credential
