We bring together the best of Microsoft AI across content understanding, search relevance, and diverse knowledge sources to help developers build intelligent, enterprise-ready solutions.\nAs a Principal Software Engineer, you will shape the end-to-end customer and developer experience for FoundryIQ. This organization-level role sets technical direction across product and service boundaries, turns ambiguous opportunities into durable outcomes, and helps customers discover, adopt, and succeed with secure, reliable AI capabilities at global scale.\nWe are looking for a principled technical leader who thrives in ambiguity, exercises sound judgment with incomplete information, and adapts as customer needs, technology, and business priorities evolve. You will raise the engineering bar by creating clarity, building alignment, and enabling teams to move quickly without compromising security, reliability, or long-term maintainability.\nYou will be a trusted technical voice for the developers who use and build our platform, connecting customer and internal developer needs with product and engineering strategy. Your influence across organizational boundaries will improve how developers adopt and operate enterprise-ready AI workloads.\nYou will advance engineering excellence across the full product lifecycle, helping the organization deliver high-quality developer experiences with speed and confidence. Your impact will span UX flows, Agentic harnesses, samples, SDKs, and web services, with an emphasis on scalable practices and continuous learning.\nSuccess in this role will be measured by durable organization-level outcomes: faster developer onboarding and delivery, increased adoption of platform capabilities, improved engineering health, reduced operational risk, and stronger technical practices that enable teams to move quickly and safely.\nResponsibilities\nLead the principled adoption and continuous improvement of AI tools and Responsible AI practices across the software development lifecycle. Establish accountability for AI-generated assets, define scalable processes and tools, use engineering health metrics to measure progress, and share learnings across the organization.\nSet technical direction for production services and improve engineering quality through automation, analysis, debugging, telemetry, and retrospectives. Strengthen diagnosability, incident prevention, secure and privacy-preserving operations, least-privilege practices, and code quality.\nRaise the technical and engineering bar across the organization by defining and modeling principled practices, mentoring technical leaders, and creating reusable mechanisms that help teams improve quality, velocity, and operational discipline at scale.\nBuild an inclusive and safe engineering culture where people have the clarity, autonomy, and accountability to do their best work. Model constructive technical debate, encourage learning from outcomes, and create space for others to lead.\nCreate clarity as goals, customer needs, technologies, and constraints evolve. Reframe ambiguous problems, communicate changes in direction, and help teams learn, adapt, and maintain momentum through shifting priorities.\nLead cross-group planning and execution by translating long-term vision and ambiguous problems into clear decisions, milestones, and measurable outcomes. Drive estimation and capacity planning, negotiate scope and technical tradeoffs, resolve blockers, and adjust execution as goals and constraints change.\nBalance delivery speed with security, privacy, compliance, reliability, and operational readiness. Establish disciplined practices for validation, flighting, rollback, incident response, and disaster recovery, and use operational evidence to reduce risk.\nPartner with internal and external developers, customers, and stakeholders to validate requirements, technical feasibility, and product outcomes. Translate qualitative feedback, usage data, and success metrics into prioritized improvements, including accessibility, globalization, security, and privacy requirements.\nInfluence technical strategy and product direction across teams without relying on formal authority.
