Staff Software Engineer (L6) - Developer Productivity — Platform Systems, AIMS Engineering

Netflix is an entertainment company developing technology that powers recommendations, search, and personalized experiences for its members. The Staff Software Engineer will own developer productivity for AIMS by building and operating developer environments, build and test infrastructure, CI/CD pipelines, internal platforms, and GenAI-powered tooling for ML researchers and engineers.

Responsibilities:

• Own the end-to-end developer experience for AIMS ML practitioners: local and remote dev environments, build and test infrastructure, CI/CD pipelines, and the tools researchers use to move from idea to production experiment
• Identify friction in day-to-day engineering and research workflows firsthand, and design tooling and abstractions that remove it at the root rather than patching around it
• Design, build, and operate large-scale build and CI/CD systems that keep build, test, and iteration times fast as the codebase, model count, and headcount grow
• Partner directly with ML researchers and engineers embedded across AIMS teams to understand real workflows, prioritize the highest-leverage productivity investments, and ship tools people actually adopt
• Build and maintain internal developer platforms and self-service tooling that reduce the operational burden on individual teams, so they can focus on ML work instead of infrastructure upkeep
• Instrument developer workflows to measure productivity — build times, iteration speed, time-to-first-experiment — and use that data to prioritize where to invest next
• Drive adoption of new tooling through documentation, migration support, and hands-on partnership with teams; treat launch as the start of the work, not the end
• Set technical standards for developer tooling across AIMS and raise the engineering bar through design reviews and architectural guidance
• Evaluate, integrate, and productionize GenAI-powered developer tooling — intelligent build/test selection, automated code review, triage automation — where it measurably improves velocity, and build the guardrails that make it safe to rely on

Requirements:

• Significant experience building and operating developer productivity infrastructure — build systems, CI/CD, developer environments, or internal platforms — at scale
• Strong software engineering fundamentals, with deep proficiency in Python and working proficiency in at least one JVM language (Scala, Java, or similar)
• Hands-on experience with distributed build systems (e.g., Bazel, Buck, Pants) and large-scale distributed data/compute frameworks (e.g., Spark, Beam)
• Working understanding of GenAI-powered developer tooling — AI coding assistants, automated code review, agentic coding workflows — and hands-on experience using these tools effectively in your own engineering practice, including judgment about where they help, where they don't, and how to validate their output
• Comfort with parallel and distributed computing, and experience operating systems at a scale where naive approaches stop working
• A track record of diagnosing developer friction from direct observation of how engineers actually work, not just from ticket queues, and shipping tooling that measurably improves it
• Ability to drive cross-team technical programs and earn adoption without formal authority — this role builds trust with ML researchers directly, not just with other infra engineers
• Comfortable moving between low-level systems work (build graphs, compilers, runtime performance) and higher-level platform and API design
• Experience with ML-specific developer tooling: experiment tracking, training pipeline orchestration, feature stores, or notebook-to-production workflows
• Experience designing or shipping GenAI-powered developer tooling as a product for other engineers — not just using it, but building it (e.g., internal coding assistants, automated review bots, agentic CI workflows)
• Contributions to open-source developer tooling, build systems, or distributed data processing projects
• Experience with compiler or language tooling, static analysis, or build graph/dependency optimization
• Experience operating high-performance computing environments or large-scale batch processing systems
