Job description

At Spotify, the AiKA squad is pioneering the future of AI-powered code generation and developer productivity. We build scalable backend systems that integrate Generative AI (GenAI) into engineering workflows, with a focus on Honk — our autonomous coding agent for large-scale code modifications and technology migrations.

By joining us, you’ll help shape how developers worldwide work with AI-powered tools, streamlining workflows and enabling innovation at scale. You’ll work at the intersection of backend engineering, AI/ML, and developer tooling in a fast-moving, startup-like environment.

What You\'ll Do

• Build and own Honk, developing the backend infrastructure for our autonomous coding agent
• Integrate LLMs and agentic workflows into production systems
• Scale backend infrastructure with robust services in Python/TypeScript at enterprise level
• Design agentic workflows that understand, plan, and execute code changes across large codebases
• Enhance developer experience by integrating seamlessly with CI/CD pipelines and developer tools
• Ensure reliability and quality by delivering testable, observable, and maintainable backend code
• Drive innovation and leadership by experimenting with new AI models and contributing to technical direction

Who You Are

• You have backend expertise with Python, Java, or TypeScript/Node.js and cloud platforms
• You understand LLMs & agentic workflows (prompt engineering, orchestration, AI tools like Copilot/Claude)
• You design scalable systems that address reliability, latency, and cost challenges in AI-powered environments
• You are experienced in DevOps (Docker, Kubernetes, CI/CD, monitoring)
• You value code quality and own systems from design to production
• You collaborate effectively across diverse teams (AI researchers, PMs, engineers)
• You thrive in dynamic environments, learning and adapting as AI technologies evolve

Where You\'ll Be

• This role is based in London
• We offer you the flexibility to work where you work best. There will be some in person meetings, but still allows for flexibility to work from home.
