About the role

You'll operate at the intersection of measurement, engineering, and product impact, owning ambiguous problems that span the entire stack and translate directly into business outcomes for hundreds of millions of users.
There is no existing performance team at Dropbox - you'll define the discipline.

Drive performance improvement on the Dropbox web application as the first focus of the role - profiling React surfaces, producing flame graphs and heat maps, identifying the highest-impact opportunities, and shipping measurable improvements
Lead the performance initiative across iOS, Android, and desktop by coordinating with internal platform experts who own those clients - setting strategy, defining measurement standards, and driving execution rather than implementing every fix personally
Build and own the measurement, instrumentation, and regression-detection systems that engineering teams across Core depend on to ship performant code
Set engineering standards for performance work across Core Engineering, and mentor IC3 and IC4 engineers on profiling, measurement methodology, and performance-aware system design
Apply AI tooling to performance work and lead the optimization of AI-assisted engineering workflows across Core, raising engineering throughput and shaping how Dropbox engineers use AI to ship better software faster

Minimum of 12 years of experience as a software engineer with 3+ years serving as a Senior.
Demonstrated experience using AI tooling to accelerate performance work - applying LLMs and AI-assisted workflows to profiling analysis, root-cause investigation, refactoring, or shipping performance fixes
Experience optimizing AI-assisted engineering workflows to improve the productivity of other engineers - selecting tools, defining patterns and guardrails, and measuring the impact on engineering throughput
Production experience with modern backend services in Python or Go that support consumer-facing client surfaces

Experience profiling and improving native iOS applications (Swift), including startup time, scroll performance, and memory behavior
Experience profiling and improving native Android applications <span class=" author-d-1gg9uz65z1iz85zgdz68zmqkz84zo2qotv4kv2jz76zz80zvz68zz77zez73
