Principal Software Engineer, Full Stack

Salesforce delivers world-class events, both in-person and virtually. As the Principal Engineer focused on architecture priorities for the Event Technology portfolio, you will play a crucial role in defining and driving the technical vision and strategy. You will oversee the architectural integrity of our platforms and ensure they align with our future state objectives, and will play a part in transforming how we work through helping define how we integrate AI tools into our daily workflows.

This leadership role requires a deep understanding of software development, architecture principles, AI fluency and a passion for innovation and excellence in scalability, performance, observability, and user experience. In addition to Events Technology, you will play a part in other public web experiences including www.tableau.com, www.mulesoft.com, and "role based" sites such as the developer, admin, and architect subdomains of Salesforce.com.

"You build it, you own it." Our engineering teams are responsible for the ongoing maintenance of our apps. Therefore this role will at times require active engagement on deployments, monitoring, incident management and response, vendor oversight, and general ongoing operational activities.

What You'll Be Doing

Build and ship high-quality, production-grade software using modern engineering practices, with AI as a core part of your development workflow — pushing the boundaries of AI development tools to deliver secure, optimized, and high-quality code.

Design and orchestrate complex systems where AI agents integrate seamlessly into human workflows, driving efficiency and innovation at scale.

Contribute to building and maintaining the shared system context, an explicit repository of system designs, constraints, and standards that enables AI to operate accurately and reliably.

Critically evaluate code (Human or AI-generated) for correctness, quality, security, and performance.

Lead the architectural strategy and direction for the Event Technology and websites portfolio, ensuring alignment with Marketing Technology's overall technology vision and business goals.

Strategically plan, design, and execute the implementation of highly scalable solutions that meet current and future business needs.

Collaborate with Architects, Lead Engineers, Product, UX, and cross-functional teams in the application design process, contributing innovative ideas and technical expertise.
