Principal Geotechnical Engineer (Open Pit & Underground)

This position puts you at the heart of one of South Africa's most respected mining groups, where your geotechnical expertise directly shapes how diamonds are extracted responsibly. You'll work on cutting-edge projects, lead smaller teams, and gain exposure to world-class mining operations. De Beers invests heavily in staff development, so you'll have access to continuous training, mentorship, and opportunities to specialise further. The role gives you practical experience managing real mining hazards, which strengthens your professional credentials and makes you highly marketable across the global mining sector. Within 1–2 years, you could progress to Senior Principal Geotechnical Engineer or move into a Geotechnical Manager role overseeing multiple sites. Some engineers transition into mining engineering leadership, resource management, or sustainability roles where geotechnical knowledge is critical. De Beers and other major operators offer NQF-aligned professional development programmes, and many engineers pursue ECSA Registration as a Professional Engineer, which opens doors to consulting or independent practice. A few years of solid experience here positions you for international mining roles across Africa and beyond. Tailor your CV to highlight specific geotechnical projects—include software you've used (FLAC, Slide, etc.), types of slopes or excavations you've designed, and any field experience. Mention your ECSA registration status clearly; if you're not yet registered, state your candidacy or timeline. Include references from previous employers who can speak to your technical competence and leadership. If you completed a WIL placement or learnership in mining, lead with that. Avoid generic statements; instead, describe one problem you solved and the outcome. Research De Beers' sustainability commitments and mention alignment with their purpose in your cover letter—they value engineers who think beyond compliance. You'll lead geotechnical engineering work across De Beers' open pit and underground mining operations, solving the technical challenges that keep mines safe and productive. This role involves designing and monitoring rock and soil stability, managing slope assessments, and collaborating with mining teams to implement innovative solutions that support responsible mining practices.
