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.

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.

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 Impact
In this role, you will drive the strategy, architecture, design, and implementation of technology initiatives across AWS, Azure, and GCP, delivering cutting-edge technology solutions.

You will define enterprise architecture, covering both cloud-native and hybrid solutions across leading cloud platforms. Your work involves designing and leading the implementation of scalable, highly available, and resilient services to ensure optimal performance and reliability. You will act as a bridge between stakeholders and technical teams, gathering requirements, creating architectural designs, and providing expert guidance. Additionally, you will lead application modernization efforts, re-architecting applications to optimize cloud performance and efficiency. You will define enterprise strategies for containerization (Kubernetes, Docker), serverless computing, and API management. Furthermore, you will architect secure and efficient cloud networking and connectivity solutions to support hybrid and multi-cloud environments.

You will direct clients on their technology modernization journey using cutting-edge technologies to assist in large-scale digital transformations, often helping to shape the client's journey and upfront technical design decisions. You will have visibility at the highest level in an organization, working directly with CIO, CDO, and CEO, allowing you to make a real impact. You will look holistically at what is required to realize impact (e.g., tech, operating model, processes, people, change management, etc.). Serving clients across a wide variety of sectors, geographies, and industries, you will have the opportunity to broaden your knowledge within the technology sector and specialize in areas of particular interest. You will also have the chance to shape your own journey as you grow within a path developed for technologists. We offer opportunities to build your own learning path to grow and develop with the support of McKinsey & Company and its global tech community.

Given the diversity of our client work, we work with a variety of technologies. More than deep expertise in a particular technology, we are looking for colleagues with a broad technical background and proven ability to quickly learn new technologies. You'll be able to shape your own learning journey/areas of interest. Typically, a client project involves one of the three major public cloud platforms (AWS, Azure, GCP), use of a scripting language for automation (e.g., Python, NodeJS), Kubernetes-based container platform, a way to manage infrastructure-as-code (Pulumi, Terraform, CDK, etc.) and CI/CD tooling and monitoring/logging platforms. In addition to these technologies we have developed a variety of technologies, including open source, to accelerate our client's success (Iguazio, Kedro, CausalNex, etc.)

You'll join McKinsey Digital in Japan. We bring together the best minds in business and technology to help our clients use cutting-edge technologies to transform their business.

As part of this team, you'll typically work on projects across industries and business functions. You will work with other Architects and colleagues of different disciplines, including data scientists and engineers, designers, business strategists, etc. Within our diverse, inclusive and distinctive teams you will deliver our technology-enabled solutions of the future. In this role you will be a key part of driving AI transformations, building new business and modernizing core technology.

Professional & personal development and innovation are two big priorities for McKinsey Digital. You will have the freedom to try new ideas and experiment in your role and will be guaranteed significant dedicated time to continuously learn with the support of your team and global network.
