Job ID: 108123

Johannesburg

Do you want to do work that matters, alongside supportive leaders who will help you grow faster than you ever thought possible? Are you a creative problem-solver who is energized by challenges? You’ve come to the right place.

YOUR IMPACT

At McKinsey’s CCN Analytics Graduate Program, you will work at the forefront of machine learning, generative AI, and emerging agentic AI technologies, helping leading organizations navigate into the age of Artificial Intelligence.

You will contribute across the full AI value chain, from shaping big-picture strategy to hands-on building and coding. You will help clients identify where AI can create value across their business, develop multi-year AI roadmaps, and define the operating models needed to deliver them. This includes thinking through team structures, required capabilities, technology stacks, and investment priorities.

You will also play a role in reimagining how business functions operate in an AI-native future. For example, you may help redesign functions such as fraud detection by integrating machine learning models, virtual AI agents, and generative AI co-pilots to enhance both efficiency and decision-making.

In addition, you will build and deploy AI solutions, developing and scaling components using modern technologies such as Python, PySpark, SQL, and cloud platforms including AWS, GCP, and Azure. You will work with advanced tools and frameworks to bring these solutions to life in real-world client environments.

Working closely with clients and McKinsey colleagues, you will combine research, expert interviews, and data analysis with collaborative problem-solving to generate insights and develop innovative models. You will then communicate your findings and recommendations clearly to client stakeholders.

You will have the opportunity to work with a diverse range of organizations, from large global enterprises to fast-growing startups, across multiple industries. Your work may span use cases such as optimizing pricing strategies, personalizing customer experiences, or supporting complex technological initiatives.

You will collaborate within cross-functional teams that bring together business and technical expertise. Your colleagues will come from a wide variety of professional and cultural backgrounds, creating a dynamic and enriching team environment.

Throughout the program, you will develop strong commercial thinking by focusing on how AI solutions drive tangible business outcomes such as revenue growth, cost reduction, and improved customer experience. You will gain hands-on experience with cutting-edge technologies while deepening your understanding of different industries and how they operate. You will also strengthen your problem-solving and communication skills, learning how to structure complex challenges and present insights in a clear and compelling way.

You will be supported by a global network of experts, comprehensive training programs, and ongoing mentorship. The program is designed to accelerate your development and equip you with skills that will support a wide range of future career paths.

YOUR GROWTH

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.

In return for your drive, determination, and curiosity, we'll provide the resources, mentorship, and opportunities you need to become a stronger leader faster than you ever thought possible. Your colleagues—at all levels—will invest deeply in your development, just as much as they invest in delivering exceptional results for clients. Every day, you'll receive apprenticeship, coaching, and exposure that will accelerate your growth in ways you won’t find anywhere else.

When you join us, you will have:

Continuous learning: Our learning and apprenticeship culture, backed by structured programs, is all about helping 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 not only encourage diverse perspectives, but they are critical 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 come up with the best solutions for our clients. Plus, you’ll have the opportunity to learn from exceptional colleagues with diverse backgrounds and experiences.
World-class benefits: On top of a competitive salary (based on your location, experience, and skills), we provide a comprehensive benefits package to enable holistic well-being for you and your family.

YOUR QUALIFICATIONS AND SKILLS

Bachelor's or master's degree in data analytics, computer science, machine learning, applied statistics, mathematics or artificial intelligence, with a strong academic track record

Experience (academic or professional) with data science tools and languages: Python (must), and possibly others like R, SPSS, SAS, or Hadoop

Willingness to work on high-stakes problems that shape industries, solving tough challenges and learning from the best

Entrepreneurial mindset with commercial instinct, and willingness to take initiative, and build the skills to lead teams, ventures, or products

Ability to take ownership of your workstream, plan your approach, and deliver results—while managing competing demands and tight deadlines

Please review the additional requirements regarding essential job functions of McKinsey colleagues.

Our unwavering commitment to integrity drives everything we do, guiding us to always act in the best interests of our clients, our people, and the communities we serve.
