Unexpected innovations from employees

Summary 
In this episode of the AI Engineering Podcast Niklas Gustavsson, Chief Architect at Spotify, talks about scaling AI across engineering and product. He explores how Spotify's highly distributed architecture was built to support rapid adoption of coding agents like Copilot, Cursor, and Claude Code, enabled by standardization and Backstage. The conversation covers the tension between bottoms-up experimentation and platform standardization, and how Spotify is moving toward monorepos and fleet management. Niklas discusses the emergence of "fleet-wide agents" that can execute complex code changes with robust testing and LLM-as-judge loops to ensure quality. He also touches on the shift in engineering workflows as code generation accelerates, the growing use of agents beyond coding, and the lessons learned in sandboxing, agent skills/rules, and shared evaluation frameworks. Niklas highlights Spotify's decade-long experience with ML product work and shares his vision for deeper end-to-end integration of agentic capabilities across the full product lifecycle and making collaborative "team-level memory" for agents a reality.

• Your host is Tobias Macey and today I'm interviewing Niklas Gustavsson about how Spotify is scaling AI usage in engineering and product work

Interview
 

• Introduction
• How did you get involved in machine learning?
• Can you start by giving an overview of your engineering practices independent of AI?
• What was your process for introducing AI into the developmer experience? (e.g. pioneers doing early work (bottom-up) vs. top-down)
• There are countless agentic coding tools on the market now. How do you balance organizational standardization vs. exploration?
• Beyond the toolchain, what are your methods for sharing best practices and upskilling engineers on use of agentic toolchains for software/product engineering?
• Spotify has been operationalizing ML/AI features since before the introduction of LLMs and transformer models. How has that history helped inform your adoption of generative AI in your overall engineering organization?
• As you use these generative and agentic AI utilities in your day-to-day, how have those lessons learned fed back into your AI-powered product features?
• What are some of the platform capabilities/developer experience investments that you have made to improve the overall effectiveness of agentic coding in your engineering organization?
• What are some examples of guardrails/speedbumps that you have introduced to avoid injecting unreliable or untested work into production?
• As the (time/money/cognitive) cost of writing code drops that increases the burden on reviewing that code. What are some of the ways that you are working to scale that side of the equation?
• What are some of the ways that agentic coding/CLI utilities have bled into other areas of engineering/opertions/product development beyond just writing code?
• What are the most interesting, innovative, or unexpected ways that you have seen your team applying AI/agentic engineering practices?
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on operationalizing and scaling agentic engineering patterns in your teams?
• When is agentic code generation the wrong choice?
• What do you have planned for the future of AI and agentic coding patterns and practices in your organization?
