We are looking for a Principal Engineer to lead the architecture and evolution of a large-scale distributed data platform that powers real-time and batch data use cases across the company.

This is a director-level IC role focused on building foundational platform systems that enable teams to produce, manage, and consume data reliably at scale. You will operate across multiple domains, setting technical direction, driving key architectural decisions, and partnering broadly to deliver platform capabilities used by a wide range of internal consumers.

In addition to strong distributed systems expertise, this role will help shape how automation and AI-assisted workflows are incorporated into the platform—improving system operability, developer productivity, and platform intelligence—while maintaining strong guardrails and reliability.

What You’ll Do

Define and drive architecture for a distributed data platform supporting real-time, streaming, and batch workloads

Lead design of core platform capabilities such as data lifecycle management, metadata systems, orchestration, and developer-facing APIs

Build systems that improve data reliability, consistency, discoverability, and ease of use across diverse internal consumers

Drive platform scalability, performance, and cost efficiency across high-throughput, low-latency systems

Introduce automation and AI-assisted workflows (e.g., intelligent diagnostics, validation, safe remediation) to reduce operational overhead and improve system resilience

Establish strong operational foundations: observability, SLOs, failure handling, and production excellence

Partner with engineering teams across the company to influence adoption, standardization, and platform evolution

Mentor senior engineers and contribute to raising engineering and architectural standards

What You Bring

~15+ years of experience building large-scale distributed systems, infrastructure, or data platforms

Experience operating at Staff+ or Principal level, leading complex, cross-team technical initiatives

Strong fundamentals in distributed systems (scalability, fault tolerance, data consistency, performance)

Experience with high-scale streaming systems, event-driven architectures, or real-time data processing

Hands-on experience building platform services that support both real-time and offline workloads

Proficiency in systems programming (e.g., Java, Python, Go) with the ability to go deep when needed

Experience running production systems with strong focus on reliability, observability, and operational excellence

Familiarity with automation or AI-assisted systems (e.g., agentic workflows, intelligent tooling) and sound judgment on where they add value

Strong communication and ability to influence across a broad engineering organization
