Bachelor's degree in Industrial Hygiene, Occupational Health, Environmental Health, Chemistry, Chemical Engineering, Toxicology, or a related technical discipline.
3+ years of professional industrial hygiene experience in manufacturing, aerospace, defense, chemical processing, energetics, or another technically complex industrial environment.
Demonstrated experience conducting occupational exposure assessments and developing sampling strategies.
Experience with industrial hygiene monitoring methods and equipment for chemical and physical hazards.
Working knowledge of OSHA occupational health requirements and recognized industrial hygiene practices.
Experience interpreting occupational exposure limits, toxicological information, sampling data, and technical process information.
Ability to evaluate workplace hazards and translate technical findings into practical exposure-control recommendations.
Strong technical writing, communication, analytical, and problem-solving skills.
Ability to work effectively with engineering, manufacturing, operations, and technical safety teams in a fast-paced environment.
Ability to periodically travel to support operations in Midland, Texas.

Nice To Haves

Master's degree in Industrial Hygiene, Occupational Health, Toxicology, Chemical Engineering, or a related technical discipline.
Certified Industrial Hygienist (CIH) credential or demonstrated progress toward certification.
Experience in aerospace, defense, propulsion, energetic materials, chemical manufacturing, or other high-hazard manufacturing environments.
Experience supporting new facility commissioning, manufacturing scale-up, or rapidly evolving operations.
Experience evaluating ventilation, containment, and other engineering controls.
Experience supporting respiratory protection, hearing conservation, and medical surveillance programs.
Familiarity with process safety and integration of industrial hygiene considerations into process and facility design.
Experience developing or scaling industrial hygiene programs within a growing organization.

Responsibilities

Develop and execute the site's industrial hygiene program, including exposure assessment strategies, sampling plans, monitoring, documentation, and periodic reassessment.
Conduct qualitative and quantitative assessments of chemical and physical hazards associated with manufacturing, energetic materials, testing, and supporting operations, including airborne contaminants, noise, and non-ionizing radiation.
Establish risk-based exposure monitoring strategies, including similar exposure groups, baseline characterization, monitoring frequencies, and reassessment criteria.
Evaluate occupational exposure risks associated with hazardous and energetic materials, manufacturing processes, testing activities, and emerging technologies.
Partner with Engineering, Manufacturing, Facilities, and Energetics Safety to identify and implement effective engineering and process controls using the hierarchy of controls.
Evaluate the effectiveness of ventilation, containment, and other exposure-control systems and provide technical recommendations for improvement.
Provide industrial hygiene input during facility design, commissioning, new equipment and process reviews, and operational changes to ensure occupational health considerations are incorporated early.
Serve as a technical resource for respiratory protection, PPE selection, occupational exposure limits, noise and hearing conservation, non-ionizing radiation, and medical surveillance requirements.
Apply and interpret applicable OSHA requirements and recognized industrial hygiene standards and guidance, including ACGIH, NIOSH, ANSI, and AIHA practices, to establish technically sound exposure assessment and control strategies.
Analyze and interpret exposure monitoring data, toxicological information, and occupational exposure limits to develop practical recommendations and communicate risk to employees and leadership.
Develop industrial hygiene procedures, technical guidance, training, and employee communications supporting occupational health programs.
Support investigations involving potential employee exposures, occupational health concerns, incidents, releases, or abnormal operating conditions.
Maintain industrial hygiene and employee exposure records in accordance with applicable regulatory and company requirements.
Periodically support industrial hygiene assessments and program needs at Castelion's Midland, Texas operations.
Support broader site EHS programs and initiatives where industrial hygiene expertise is required.
