Description
The Microsoft Content team powers AI-driven experiences for more than 1 billion users across Copilot, Bing, Edge, Windows, and Xbox. We are seeking a Principal Software Engineer to define and lead the technical direction for the next generation of intelligent, large-scale content platforms.
In this role, you will be responsible for shaping multi-year technical strategy, driving architectural coherence across organisations, and building systems that serve as foundational platforms for multiple product surfaces. You will lead the design and evolution of distributed backend systems, cloud-native infrastructure, and data platforms that operate at global scale with strict requirements for availability, latency, security, and cost efficiency.
These systems form the backbone for intelligent user experiences and must be designed for long-term extensibility and operational excellence. Building on this foundation, you will guide the integration of LLM-powered capabilities into production systems,defining patterns for retrieval, orchestration, evaluation, and responsible AI. You will ensure these capabilities are not isolated features, but deeply embedded, reliable, and scalable parts of the platform.
This role requires exceptional technical judgment, the ability to operate in highly ambiguous spaces, and a track record of influencing across teams and organisations. You will work closely with engineering leaders, product leaders, and applied scientists to align technical investments with long-term business outcomes.
Microsoft’s mission is to empower every person and every organisation on the planet to achieve more. As employees, we come together with a growth mindset, innovate to empower others, and collaborate to realise our shared goals. Each day, we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
