About the Role
Unstructured is looking for a Senior Principal / Distinguished Engineer to define the architectural foundation for how enterprises process and transform unstructured data for large-language-model (LLM) applications.
This is a high-impact, hands-on role for someone who thrives in deep systems work—someone who could write the book on Kubernetes, lives and breathes Python, and understands Postgres at the index and transaction-log level. You’ll own the technical direction for our core platform, guiding how data moves through every layer—from ingestion to transformation to retrieval.
You’ll partner closely with the Head of Engineering, Head of Infrastructure, and product leaders to ensure Unstructured’s systems are performant, resilient, and ready to support the next generation of AI-driven workloads.
SF/Bay Area preferred - not required.
Responsibilities
Define and evolve the end-to-end architecture for Unstructured’s data transformation and retrieval platform.
Build and scale distributed systems that process massive volumes of unstructured data across diverse formats and sources.
Serve as the company-wide authority on Kubernetes orchestration, cluster design, performance tuning, and reliability.
Lead Python architecture and best practices—ensuring performance, modularity, and maintainability across services.
Design and optimize Postgres schemas, queries, and indexing strategies to support large-scale metadata and retrieval pipelines.
Mentor senior engineers through design reviews and code guidance, raising the bar for technical excellence across the org.
Partner with the infrastructure and product teams to translate research prototypes into production-grade systems.
Evaluate emerging technologies and open-source tools in LLM infrastructure, retrieval, and orchestration—deciding where and how to integrate them.
You Might Be a Fit If You
Have 15+ years of software engineering experience with a focus on distributed systems, infrastructure, or data architecture.
Are a Python expert—capable of building frameworks and performance-critical services from scratch.
Have deep Kubernetes expertise; you can design, deploy, and debug at scale and could teach others how to productionize it securely.
Are fluent in Postgres—you understand query planning, partitioning, and tuning for high-throughput environments.
Are obsessed with clean, scalable architecture and can lead design reviews that shape how entire systems evolve.
Have experience in high-performance data or AI/ML systems—especially those involving retrieval pipelines, embeddings, or hybrid workloads.
Thrive in fast-moving, ambiguous environments where technical depth and judgment matter more than process.
Bonus Points/Nice to Have
Experience building or scaling LLM-powered or RAG systems in production.
Familiarity with open-source orchestration frameworks, vector databases, or hybrid cloud infrastructure.
Contributions to open-source projects in Python, Kubernetes, or distributed systems.
Why This Role Matters
At Unstructured, we’re building the core infrastructure layer that powers enterprise-grade retrieval-augmented generation and unstructured data transformation. The systems you architect will define how data moves through every layer of that stack. You’ll shape the foundation that enables organizations, and the models that serve them, to reason over the world’s information.
Compensation
Competitive salary + equity + full benefits package. Level and title (Senior Principal vs. Distinguished) will be based on experience and scope of impact.

The Company
What We Do
At Unstructured, we're on a mission to give organizations access to all their data. We know the world runs on documents—from research reports and memos, to quarterly filings and plans of action. And yet, 80% of this information is trapped in inaccessible formats leading to inefficient decision-making and repetitive work. Until now.
Unstructured captures this unstructured data wherever it lives and transforms it into AI-friendly JSON files for companies who are eager to fold AI into their business.
