Senior In-Situ Recovery Engineer

About Hades Hades is a modern mining company on a mission to transform how the world accesses critical resources and energy. Founded in 2025, we’re developing ultra-deep drilling technologies that push the limits of what’s possible underground. Based in Munich, we’ve raised €20M in pre-seed and seed funding from leading European resilience investors. We’re now building a world-class team to bring this vision to life. Why Join Hades? At Hades, you'll be part of a high-growth, high-impact deep-tech startup making a tangible difference. Our mission is critical: to secure sovereignty for Europe through the responsible and efficient extraction of vital materials and energy. We offer: Impactful Work: Contribute directly to solving global challenges related to resource scarcity and energy independence. Cutting-Edge Technology: Work at the forefront of ultra-deep drilling, leveraging advanced engineering and innovative approaches. Growth Potential: Join a rapidly expanding company with significant opportunities for personal and professional development. Dynamic Environment: Thrive in a fast-paced, collaborative, and entrepreneurial setting in the heart of Munich. Purpose-Driven Mission: Be part of a team dedicated to a sustainable and secure future for Europe. The Role As a Senior In-Situ Recovery Engineer at Hades, you will build and lead the technical foundation of our In-Situ Recovery (ISR / ISL) business line. You'll bring proven ISR expertise - most likely earned in uranium or copper - and apply it to recovering critical minerals from European deposits, including geologies that conventional ISR has not been able to reach. Part of your remit is to work with our founding team on how Hades' ultra-deep drilling technology can extend ISR into deeper and harder host rock than the sandstone-hosted operations the industry knows today. Responsibilities Evaluate deposits for ISR amenability — ore-body delineation, host-rock permeability, hydrogeology, and geochemistry Design wellfield layouts: injection, production, and monitoring wells, including patterns, spacing, and surface infrastructure Build hydrogeological and reactive-transport models (e.g. MODFLOW, FEFLOW, PHREEQC) to forecast flow, recovery, and excursion risk Develop leaching strategies and lixiviant chemistry in coordination with the downstream process plant Plan and engineer pilot wellfields end-to-end, from well construction through commissioning Define monitoring, excursion-control, and environmental-risk strategies; support permitting and stakeholder engagement Work with the founding team to integrate Hades' drilling technology into ISR and extend its reach into new geologies Qualifications 5+ years of hands-on experience in In-Situ Recovery / In-Situ Leaching (uranium, copper, or other commodity) Solid grasp of hydrogeological modelling and groundwater flow analysis (MODFLOW, FEFLOW, or equivalent) Experience designing leaching strategies and wellfield-to-plant integration Familiarity with wellfield planning, well design, and mechanical integrity Understanding of environmental and regulatory risk for ISR projects Excellent written and oral communication skills in English Willingness to relocate to the greater Munich area (we provide relocation and visa support) What sets ​you apart Field experience commissioning or operating an ISR wellfield Familiarity with reactive-transport and geochemical codes (PHREEQC, GoldSim, TOUGHREACT) Exposure to ion exchange, solvent extraction, or precipitation processes Experience adapting ISR methods to non-sandstone or unconventional host rock Experiment-driven, systems-level thinking across geology and process engineering Interest in emerging extraction technologies and novel drilling methods Why Hades? We offer An opportunity to make a huge impact on the future of Europe by increasing resilience and providing a path to resource and energy sovereignty A human-centered company culture with super nice and supportive colleagues A great sense of community through team events and fun in and outside the office Highly competitive compensation and benefits package If you are passionate about pushing the boundaries of technology and contributing to a more sustainable future, we encourage you to apply now.
