at Sixth Street

🏢 About Sixth Street

Sixth Street is a global investment firm that provides flexible, long-term capital solutions to enable sustainable growth for companies. What makes them unique is their focus on partnership-driven investments across multiple asset classes, offering stability and strategic support rather than short-term returns. Someone might want to work there to contribute to meaningful, long-term financial solutions while being part of an engineering organization that values platform thinking and AI innovation.

About This Role

This role involves building and evolving self-service platform capabilities ('Golden Paths') to accelerate engineering delivery through templates, libraries, and sample applications. You'll drive cross-team platform initiatives, facilitate alignment and migration plans, and evolve AI platform capabilities including AI gateway services and governance patterns. It's impactful because you'll directly reduce cognitive load for engineering teams and enable the firm's AI strategy through scalable platform solutions.

💡 A Day in the Life

A typical day might involve collaborating with engineering teams to understand their platform needs, designing and implementing self-service capabilities through templates and libraries, and working on AI platform components like gateway services. You'd spend time documenting 'Golden Paths,' partnering with teams on adoption, and refining instrumentation patterns for metrics, logs, and traces across the organization.
