Who You’ll Work With

Driving lasting impact and building long‑term capabilities with our clients is not easy work. You are the kind of person who thrives in a high‑performance/high‑reward culture—doing hard things, picking yourself up when you stumble, and having the resilience to try another way forward.

• Continuous learning: Our learning and apprenticeship culture, backed by structured programs, helps you grow while creating an environment where feedback is clear, actionable, and focused on your development. The real magic happens when you take the input from others to heart and embrace the fast‑paced learning experience, owning your journey.
• A voice that matters: From day one we value your ideas and contributions. You’ll make a tangible impact by offering innovative ideas and practical solutions, all while upholding our unwavering commitment to ethics and integrity. We encourage diverse perspectives, recognizing their critical role in driving us toward the best possible outcomes.
• Global community: With colleagues across 65+ countries and over 100 different nationalities, our firm’s diversity fuels creativity and helps us devise the best solutions for our clients. You’ll also have the opportunity to learn from exceptional colleagues with diverse backgrounds and experiences.
• World‑class benefits: In addition to a competitive salary (based on your location, experience, and skills), we provide a comprehensive benefits package to support your holistic well‑being and that of your family.

Your Impact

You will join a dynamic team at the forefront of technological innovation within the Metals & Mining practice. You will work in small, highly collaborative agile teams, using modern technologies to deliver high‑impact solutions. Your contributions will span rapid prototypes and full‑scale enterprise applications, letting you see the direct business impact from day one. Our teams combine open‑source technologies, enterprise platforms, and AI‑enabled capabilities to build scalable, cost‑effective systems.

You will collaborate closely with system architects, development managers, and consultants to deliver intelligent web‑based and mobile applications that meet business goals. You will play a leading role in shaping our technical direction and in integrating cutting‑edge Generative AI capabilities to create industry‑shaping products. You will join the team in the Wroclaw or Lisbon office. We are open to considering applications at different levels: Software Engineer, Senior SE, or Principal SE.

We are currently executing our MineSpans 2.0 vision, which aims to embed Generative AI across our data processes to completely transform how we ingest, transform, discover, consume, and provide clients with data and insights. We are also extending this vision to the entire Metals & Mining practice, aiming to rewire the practice by leveraging the latest AI developments.
