An Optical Mineralogy job involves studying minerals using polarized light microscopy to identify and analyze their optical properties. Professionals in this field work in geology, mineral exploration, and material sciences to determine mineral composition and structure. They use techniques like thin-section analysis to identify minerals based on birefringence, pleochroism, and refractive indices. This work is crucial in fields such as petrology, mining, and environmental science. Optical mineralogists may work in laboratories, universities, or industries that require detailed mineral characterization.
A typical day for an Optical Mineralogist involves preparing thin sections of rock or mineral samples, conducting detailed analyses using petrographic microscopes, and documenting observations. You may spend time collaborating with other geoscientists or lab technicians to interpret findings and support research or exploration projects. Some days also include recording results, preparing reports, or teaching techniques to students and colleagues. Work environments are usually a mix of laboratory and office settings, with opportunities for fieldwork depending on the employer and project demands.
To excel in Optical Mineralogy, a strong background in geology, mineral identification, and petrography is typically required, often supported by a relevant degree in geosciences. Expertise with petrographic microscopes, polarized light equipment, and image analysis software is essential, and some roles may require specific laboratory safety certifications. Strong analytical thinking, attention to detail, and clear written and verbal communication are highly valued in this role. These skills are crucial for accurately analyzing mineral samples and effectively conveying findings to peers or clients in academic, industrial, or environmental settings.

WJE Austin is home to WJE's second-largest laboratory facility, and we are seeking an experienced Petrographer to join our local team. Bring your problem-solving mindset, insatiable curiosity, and developing technical expertise to a team that is genuinely excited about their work and invested in each other's success.
As a Petrographer at WJE, you will apply a principles-first, problem-solving approach to determine root causes of problems, characterize materials, and evaluate performance for a variety of cementitious materials applications across the architecture, engineering, and construction (AEC) industry.
Our industry-leading team of petrographers contributes to investigations involving concrete, mortar, aggregate, dimension stone, stucco, and other building materials, including problems such as alkali-aggregate reaction (AAR, including both ASR and ACR), mix design verification, low strength, cement-admixture interaction, efflorescence, delamination and other surface defects, fire-damaged concrete, cracking, sulfate attack, freeze-thaw damage, and delayed ettringite formation (DEF).
We leverage multiple state-of-the-art methods, such as optical microscopy, fluorescence microscopy, image analysis, laser-induced breakdown spectroscopy (LIBS), and electrical resistivity, and have access to additional capabilities and a broader team of materials scientists in WJE's Janney Technical Center.
In addition to managing projects for external clients, our petrographers collaborate with engineers and architects across WJE to solve interesting and complex problems in the built world, ranging from historic preservation and collapse investigations to new construction challenges.
Flexibility in Position Level:
Recognizing the unique combination of skills applicable to the niche practice of forensic petrographic analysis, we are open to considering candidates at a variety of experience levels for this position. Whether you are early in your career or an established expert, our team is ready and willing to provide commensurate support, mentorship, and training necessary to set you up for long-term success.
Typical Responsibilities of Early-Career Associates:
Contribute to the day-to-day success of multiple concurrent projects and complete work with limited oversight, under the guidance of experienced petrographers
Perform hands-on petrographic analyses, microscopy, field assessment, and physical testing, such as compressive strength and durability testing
Accurately record and organize data for analysis, while exercising good judgment in assessing the reasonableness of test results
Assume responsibility for key aspects of laboratory safety, maintenance, and quality assurance, including setting up, operating, and maintaining laboratory instruments; cleaning glassware; restocking laboratory supplies, reagents, and solutions
Qualifications / Key Competencies:
Bachelor's degree or higher in geology, materials science/engineering, geological engineering, or a related field with substantial coursework in mineralogy, petrology, and geochemistry; advanced degree preferred
Minimum two years of applied petrographic laboratory experience; industry experience preferred to experience gained solely in an academic setting
Strong foundation in optical mineralogy, petrology, and petrographic sample preparation, including the following methods: traditional petrographic microscopy; thin section analysis; immersion mount analysis; hand sample analysis with a stereomicroscope; point-count and modal analysis; and preparation of thin sections, polished sections, lapped hand samples, etc.
Excellent technical, written, verbal, and interpersonal communication skills
Ability to prioritize tasks and adapt to changing demands while maintaining a high standard of excellence, integrity, and attention to detail in a fast-paced environment
