Job Description & Summary

At PwC, our people in software and product innovation focus on developing cutting-edge software solutions and driving product innovation to meet the evolving needs of clients. These individuals combine technical experience with creative thinking to deliver innovative software products and solutions.
Those in software engineering at PwC will focus on developing innovative software solutions to drive digital transformation and enhance business performance. In this field, you will use your knowledge to design, code, and test cutting-edge applications that revolutionise industries and deliver exceptional user experiences.
Growing as a strategic advisor, you leverage your influence, expertise, and network to deliver quality results. You motivate and coach others, coming together to solve complex problems. As you increase in autonomy, you apply sound judgment, recognising when to take action and when to escalate. You are expected to solve through complexity, ask thoughtful questions, and clearly communicate how things fit together. Your ability to develop and sustain high performing, diverse, and inclusive teams, and your commitment to excellence, contributes to the success of our Firm.
Examples of the skills, knowledge, and experiences you need to lead and deliver value at this level include but are not limited to:
Craft and convey clear, impactful and engaging messages that tell a holistic story.
Apply systems thinking to identify underlying problems and/or opportunities.
Validate outcomes with clients, share alternative perspectives, and act on client feedback.
Direct the team through complexity, demonstrating composure through ambiguous, challenging and uncertain situations.
Deepen and evolve your expertise with a focus on staying relevant.
Initiate open and honest coaching conversations at all levels.
Make difficult decisions and take action to resolve issues hindering team effectiveness.
Model and reinforce professional and technical standards (e.g. refer to specific PwC tax and audit guidance), the Firm's code of conduct, and independence requirements.
The world runs on data. It flows between machines, platforms, clouds, and people - and the organizations that harness it intelligently win. At PwC's Digital Integration & Architecture practice, we're the architects of that future. We help the world's most ambitious companies reimagine how their technology talks, thinks, and acts - and we're looking for exceptional people to help us lead that charge.
What We Do:
We sit at the intersection of technology strategy and real-world execution. Our team designs and delivers the integration fabric and platform architectures that power modern enterprises - from cloud-native API ecosystems and event-driven architectures to AI-infused data pipelines and intelligent automation.
But this isn't just engineering. It's vision. We advise C-suite leaders and technology executives across every major industry on how to think differently about their architecture - how to move from legacy monoliths to composable, AI-ready platforms that can adapt at the speed of business.
We bring the latest thinking in Artificial Intelligence to every engagement. We challenge clients to ask bigger questions: How can AI reshape your integration strategy? How do you architect systems that don't just connect machines - but enable machines to think alongside humans? These are the conversations we live for.
The Role:
As a Senior Manager in our Digital Integration & Architecture practice, you'll be an enterprise-scale change agent - shaping vision with executives, governing complex delivery, and building the capabilities clients need to sustain change.
You'll lead multi-track programs end to end, orchestrating strategy, architecture, and execution across platforms, teams, and partners. You'll own key client relationships, collaborate with Partners on origination, and ensure our work delivers measurable business value, not just technical excellence.
