## Description

As a Principal Engineer at Dropbox, you will own company-critical, loosely defined technical problems with multi-year impact, operating at the intersection of technology, product, business strategy, and applied AI.

You will define long-term technical direction for customer-facing experiences used by millions, identifying where AI meaningfully improves customer value and translating evolving business context and industry advances into durable, multi-area strategies and roadmaps that shape how Dropbox builds, scales, and innovates, while remaining hands-on in software development where it provides the greatest leverage.

Your influence will span organizations, setting foundational architecture, driving execution standards, and aligning senior technical and product leaders across boundaries.

## Responsibilities

- Own and drive technical outcomes across multiple teams and organizations, delivering company-critical customer and business impact at scale.

- Define long-term technical strategy and partner with senior Product and Engineering leaders as the technical owner for the most important company objectives.

- Tackle the most ambiguous and far-reaching technical and product problems, shaping what the company builds as much as how it builds it.

- Remain deeply hands-on in software development, owning and implementing the most critical, complex, and foundational parts of the system where leverage is highest.

- Influence and align roadmaps across organizations, resolving structural bottlenecks and changing how Dropbox builds and operates.

- Architect and evolve foundational systems and platforms that enable new product capabilities and operate reliably at the scale of hundreds of millions of users.

- Model exceptional technical judgment and execution rigor, setting and sustaining high engineering standards across a distributed, virtual environment.

- Drive AI adoption both to increase productivity and to produce AI-based features.

## Requirements

- Advanced degree in Computer Science or a related technical field involving substantial software development, or equivalent industry experience demonstrating deep technical mastery.

- 15+ years of experience designing, building, and evolving large-scale software systems with sustained impact across multiple teams or organizations.

- Demonstrated success operating at a Principal level, owning company-critical technical problems and influencing long-term technical direction.

- Strong experience building consumer-facing products at scale, with a deep understanding of user experience, performance, reliability, and operational excellence.

- Broad and deep technical expertise across multiple domains, including several of frontend, mobile, search, databases, storage systems, concurrency, and distributed systems.

- Practical experience applying modern ML, LLM-based APIs, and agentic frameworks in production systems, with sound judgment around quality, cost, and risk.

- Ability to communicate complex technical concepts clearly and persuasively to senior engineering, product, and executive audiences.

## Preferred Qualifications

- Experience defining and scaling company-wide platforms or architectural standards that are adopted across multiple organizations.

- Proven track record of leading the introduction of new technologies such as AI or ML into core products or engineering workflows with durable impact.

- Experience operating in highly distributed, virtual-first engineering organizations at global scale.
