We are searching for a high agency and highly experienced Lead Metallurgist / Mineral Processing Engineer to join our Technical Services team. We are looking for someone with familiarity of geometallurgy and some knowledge of resource modelling to oversee all aspects of mineral resource evaluation, including auditing of data analysis, geometallurgical block models and ensuring quality control. You will provide input into the development and implementation of the Stratum Machine Learning technology to ensure accurate and reliable geometallurgical models are generated.

The role requires a proficient understanding of geometallurgical concepts for a variety of block models. Much of your day-to-day work will be focused on evaluating the clients existing kriging models, the newly generated Stratum models as well as liaising with the Business Development team to determine how our technology can add value to a client's mining operations. You will collaborate closely with our co-founders, Chief Geologist and Lead Resource Geologist to ensure Stratum’s goals are aligned.

This is a remote-first position, with a preference for applicants based in Australia or Canada.

StratumAI & the ML/AI Technical Services team

StratumAI creates advanced geometallurgical and mineral resource block models that empower operating mining companies to make smarter, more efficient decisions for mine planning and ore control. We using proprietary algorithms adapted for neural networks, to produce 3D models that are significantly more accurate than traditional Kriging models. This enable enhanced target drilling, blast hole optimisation, ore type categorisation and mineral processing routing / blending to optimise added value opportunities for the client.

Our long-term vision is to build a ML/AI engine capable of modelling many of the critical decision within a mining operation. We are looking for highly competent resource geologist to help make this vision a reality.

About Stratum

We're Stratum, a mining software company with machine learning models as our core product. Our 3D maps predict how gold, silver, copper, etc. are distributed (and how much!) using only small amounts of data, unconventional data processing, and proprietary ML protocols. Our work directly affects how much money a mine is going to make next week/month/year while reducing waste/cost. We're supported by Founders Fund, Aramco, Builders VC, Y Combinator, and Ilya Sutskever, former Chief Scientist at OpenAI, who have recognized the potential of our industry-disrupting technology.

Our long-term vision is to build a massive AI engine capable of making every decision in a mining operation, down to moving individual rocks. If you’re an exceptional engineer interested to helping make this vision a reality we look forward to reviewing your application and working together.
