Do you want to work on complex and pressing challenges—the kind that bring together curious, ambitious, and determined leaders who strive to become better every day? If this sounds like you, you’ve come to the right place.

Your Impact

As a Tech Architect at McKinsey Digital, you will play a pivotal role in shaping the strategy, architecture, design, and implementation of technology initiatives across AWS, Azure, and GCP. Your expertise across industries will be highly valued as you deliver innovative, scalable, and resilient solutions for our clients.
You will be responsible for many different elements, including but not limited to: defining and implementing strategies for cloud-native and hybrid solutions tailored to meet the unique needs of clients across industries; re-architecting legacy systems to optimize performance, scalability, and efficiency in cloud environments and guiding clients through large-scale digital transformations, working with C-level executives to align IT and business priorities.
You will also design and implement secure, efficient, and scalable cloud networking and connectivity solutions for hybrid and multi-cloud environments; lead teams in the technical implementation and integration of on-premises, hybrid, and cloud platforms (SaaS, PaaS, IaaS), ensuring scalable, reliable, and cost-efficient solutions; and work with diverse teams, including data scientists, engineers, designers, and business strategists, to deliver impactful, technology-enabled solutions.
Your work will transform businesses and position you as a trusted advisor, helping clients navigate complex technical challenges and achieve their strategic goals.

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.
